Help me with industry sign banking colorado presentation safe
[Music] thank you all for having me and attending tonight I was speaking of some folks as we were gathering here including Blair and some other Cu students that I gave a similar presentation last week at an event called switch oh and this one's self advancing to switch is an event that there's five minutes to speak on what is it 20 slides in five minutes they move on their own and it's a lot to cram in in that time period hopefully with some more time here I don't know if that's gonna be easier or harder I'm gonna have to wrestle I think this self advancing that might be some results of the self advancing from last week's presentation but to that end definitely going to dive a little deeper expect some questions feel free to interrupt as I go along here and think about that these timings maybe we'll see if it sticks otherwise I'm gonna have to race through there's only 15 seconds per slide so I am the team lead for Excel energies Colorado solar programs as mentioned run on-site solar solar Gardens and also increasingly battery interconnections but I do want to start off with just some introduction to Xcel Energy for those that don't know and also just a bigger picture of some of our ambitions when it comes to clean energy customer programs are certainly a piece of that equation but also large investments in other clean energy alternatives our piece of it as well so with that I'm just an overview and introduction Xcel Energy is in eight different states mostly kind of along the lines of the Midwest and West Region it's a great place for wind great place for solar and we serve three point six million electric customers and 2.2 million of natural gas customers as I think about the natural gas I'm reminded that today is actually PS goes public service of Colorado's one hundred and fiftieth anniversary on today was when the kind of first origins of Xcel Energy were born starting as a natural gas company providing basically Street lighting through natural gas eventually of course that lighting turned into electricity and things have evolved in innovation has occurred since then but 150 years today was when the the origins of Xcel Energy so there's a long history with energy continues to be important for our society and our economy I'm personally proud to work for Xcel Energy and all the innovative solutions that were working on to provide that clean affordable energy across these eight different states across the company as well we do have three strategic priorities lead the clean energy transition enhance customer experience and keep our bills low and in some cases there are tensions and in other cases increasingly they all kind of come together and that's a little bit what I'm going to talk about today is really how each of those three priorities we had to hit them all sometimes we have to prioritize one over the other but for the most part as we see costs of renewable energy coming down that helps to heat bills low but also to lead the clean energy transition while also offering customer programs to provide that positive customer experience so I alluded to some of the clean energy ambitions right now or have reduced 38% of our carbon emissions since 2005 and are on track to meet our goal of 80 percent lower carbon emissions by 2030 and then have our ambitions to reach 100 percent carbon free electricity by 2050 and one of the interesting pieces of this is the we do know how to get to 80 percent by 2030 we have some work really excel energy and also collaboratively have some work to do to get to that 100 percent carbon free goal it's going to take a lot of innovation of Technology some smart business minds and much much more so it's great to see a mix of folks in the room here that are entrepreneurial as we're all students kind of thinking about what the next big thing is those numbers were largely related to carbon emissions I do want to call out more kind of the the renewables for a minute we do have approval to proceed to 55 percent renewables by 2026 with 1,100 megawatts of wind 700 megawatts of solar 275 megawatts of battery storage and an early-retirement of to coal coal generating generators this is putting renewables across the service territory for the most part along the Front Range and a little bit into the mountains when it comes to some of these wind and solar projects as well as batteries again feel free to interrupt as we go along here Comanche is down in Pueblo as I speak to renewables I do want to caveat a little bit that there is a challenge of reaching 100% renewables and our goals are 100% carbon free and some of that's really related to keeping in line with our strategic goals of keeping bills low while also trying to continue to prove that clean energy transition which can incorporate and very much will incorporate a lot of wind and solar I think there's other solutions that can keep our grid reliable and safe in addition to that wind and solar that we're going to have to incorporate into the mix in a clean way just build on that a little more a meta-study was completed kind of just broadly looking at the analysis of what would it take to be a 100% renewable and really in order to accommodate the swings of wind and solar energy during different seasons in different during different times of day you'd have to over build the grid by about eight times and so that's something that certainly has some impacts on land use as well as costs and is something that we're have looked at and are taking into consideration as we do plan for some big goals to add a lot more renewables but want to do it in that cost-effective way so it I don't that one does not have storage necessarily and to your point of storage that also is absolutely a piece of equation for short-term but we do need new technologies to accommodate kind of the longer-term energy needs to fill the gaps on a seasonal basis so that I find ludicrous because that's what you're showing is no change in demand whatsoever and having just a very static profile and then what we're building it traditionally as any fossil fuels we would like I look at that and I just laugh so why would you even present that because it is a reality of kind of the potential bookmarks of what we're looking at and [Music] absolutely yeah yeah no I think we absolutely no no there this is this is one of the bookends we're gonna bring it back to what the reality is and this is yeah and and also just gonna set the stage and create that bookend is batteries are absolutely a piece of the equation and whether that's battery storage today of batteries and homes their short term duration for the most part of a couple of hours also we do not absolutely need longer-term storage batteries mechanical storage maybe chemical storage that will help for the longer-term seasonal variation of wind and solar weight murders as opposed to battery surges battery pumping all our batteries of the cars for surveying we're not making them fast enough on the screws to supply the demand so utility companies got would be on electrochemical batteries and lift weight yeah captain Creek is one of the hydro pumped hydro plants that are up in Georgetown one has been a great asset just for clean energy for for many decades it is undergoing an upgrade right now to provide more capacity it'll be really important for accommodating more renewables as we proceed more kind of mechanical and lift type products I think is something that we're exploring but is not something that's put in the ground today I think to get to that last 20% pretty much I mean all options are on the table we need to explore them and kind of prioritize them a bit but that may be a piece of the equation and as I do mention the hundred percent challenges of a hundred percent renewable energy as we worked for 100 percent of carbon free energy that doesn't mean that individual customers can't make their moves and I think market themselves as being 100% renewable or kind of speed along the transition and so these are four different solar for different renewable energy programs are available today that include renewable energy credits in some cases that from my marketing perspective or otherwise incrementally adding new renewables to the system helped us along this transition so this is really my day-to-day is the solar rewards program which is largely on-site solar there's more than 50,000 installations here in Colorado now ranging from on-site installations for homes to two of the largest solar installations that were just completed here earlier this year that are on-site for the largest rooftop solar installation and Amazon facility which is nine nine acres of rooftop space filled with solar and then also 54 acres of solar at IBM up in North Boulder so that's absolutely one method is putting that on-site solar that's putting the electrons into the building and if there is excess generation putting it out onto the grid solar rewards community as a solar garden program and is something that really Colorado was pioneering in and was one of the first to offer solar Gardens which is a up to two megawatts next year will be up to five megawatt solar facility and that's something that customers can subscribe to so they don't need to put it on the roof that can benefit from some of the bill credits any cost advantages from these solar installations there right now I figure if I included it but there are we're about to double the installation capacity so I think we're at about 80 megawatts of installations right now and about our early 2021 it'll be at about 200 megawatts so it'll double and capacity and then kind of well and there's a little bit of lag there's awarding the projects and then the projects take two years to build once they're built then the customers are receiving the bill credits and subscribing to it and so usually once there and kind of a subscription level hopefully the developers really would like to have those line up perfectly but there ya will be both confirm a capacity install perspective as well as participation will more than double in the next year and a half know their their third-party installed there's a mechanism set up that customers get bill credits of about six or seven cents depending on their depending on the rate class and then it is sold and offered by third parties that are installing and constructing the projects we do have renewable connect which is offered by Xcel Energy and that is fully subscribed today that's a 50 megawatt solar plant out in deer trail and does include the renewable energy credits for those that want to kind of be true to the ownership of the renewable energy credits and the renewable energy claims it also does have both a bill credit and also a bill charge for the renewable energy production and then there's wind source has been around for 20 plus years now I think and is a premium price program but is something that helps to contribute to the renewable energy the reset the Renewable Energy standard adjustment budget that funds a lot of the incentives for these programs to help getting get projects going it's big myah as i mentioned before i think is 1,100 megawatts of solar where have we in Colorado and Wyoming and really long the Midwest have been endowed with some great great wind sources Britain wind resources so there's a lot of opportunity there we're fortunate to be able to soak up a lot of that as energy users here in Colorado as far as the in that 11 I think it's 1,100 megawatts will be installed by 2026 maybe a little bit earlier than that there was 600 of that was at Rush Creek that was completed at the end of last year if I believe correctly that was 600 megawatts of solar Arab wind could change the new darkness to be of type gigawatts and science is that kind of retroactively applied to ones that are already set up [Music] so this background for others there was legislation that was passed earlier this year that increased there was the maximum solar garden size from 2 megawatts up to 5 megawatts and with that there's some other regulatory processes that follow from the legislation up to the Public Utilities Commission and then ultimately to our programs transfer question there are of that what I say 80 plus megawatts of projects that have been awarded today through a competitive bidding process those will need to be 2 megawatts for the equity of the competitive bidding process but for projects in the future if you want to add 3 megawatts to that then 5 megawatts is definitely something that they can kind of happen to megawatts my previous year correct and really where the the one of the big drawing lines is a parcel of land and so yeah you can have a 5 megawatts including say two plus three megawatt garden on one piece of one parcel legal parcel for projects that you're combining from a 2000 pending 20-20-20 award with a current award with source and removal do you know if C bowler is enrolled in those programs I don't know and one of the reasons for that is for me personally in kind of looking at these four different programs the top two are marketed and mostly sold by third parties the bottom two are sold and marketed by Xcel Energy and so there is a line that's drawn and organizationally that I'm not involved in the bottom two I'm in the top two and so I'm not as well-versed in in the bottom two as far as who's subscribing to it okay so see has a cute third reading ownership contracts on some buildings including the UFC and and I think there's a solar carcass over here anyway someone else has ownership with that they sell electricity see you certain amount and I think it's on like the EastEnders website yes there's some on-site solar here don't you like PBA's parties but just taking a place for you know organizational artists this for us to be a leader and to move towards it 100% you know procurement for renewables it seems like renewable connected wind source would be viable options without having to do huge on-site installation or PPP a something else we could just enroll in like this if it was buying so again with those bookends of kind of the extreme of over building by eight times and bringing it back to customer programs will contribute to that there's also energy efficiency programs that have been offered for for at least a decade largely one I mean there's 150 different programs from insulation for your home which may help a little bit on air conditioning as well as your natural gas consumption to large-scale process and custom programs for more manufacturing facilities to date that has helped to avoid the installation of 2420 power plants and six hundred and twenty eight thousand tons of carbon one of the things about this is we kind of look at some of those metrics is largely about the energy and bring overall kilowatt hours down but as time goes on one of the things I know we'll be looking at in addition to being more efficient with our energy usage is being more efficient at specific points in time and so that's really where integrating renewables with the load can help to reduce that need for eight times over building and a piece of that as we look at the portfolio of energy resources definitely includes kind of there's more variable renewables solar wind some of the hydro facilities we have more of the Fast Burst balancing from energy storage the Navy in homes might be midsize business installations and then also a larger scale demand response which is curtailing for the most part curtailing whether it's an air conditioner in your home through our saver switch program or larger scale mechanic our commercial and industrial facilities that are able to curtail some of their bigger equipment the bottom piece do you want to call out is the Ferb low low carbon resources and all of this as a whole is really going to be important but that piece in particular as we do get away from coal and other traditionally more form form resources that's a big important piece to both having a reliable grid and keeping it cost-effective if you take that piece out it gets real expensive real fast and so that's something where the innovation really needs to happen for geothermal solutions perhaps nuclear maybe the carbon sequestration hydrogen storage and more so I believe there's one biomass facility yeah I can only guess I ha
e to look that up for you I think and I think there is also a biogas as well more from farming and or waste so with this talked a little bit about kind of some of the scenarios of our system the other scenario is really the interaction with our environment and we worked with D you to analyze all the different scenarios of sorry of potential scenarios of keeping and limiting global warming below two degrees Celsius and so in this scenario I'm kind of the gray area is all those different scenarios of where everything is above two degrees Celsius you'll see the trajectory that we're on continues to stay below two degrees Celsius we're also in attracting with the one point five that I think we also increasingly hear about as well so overall when I talk about some of these big installations the 80 percent carbon reduction by a 2030 100 percent by 2050 that's something that customers really don't need to lift a finger to do it's something that Excel energy will be banking investments on large scale for the most part you'll still flip on your lights hopefully play an informal electricity bill and it will continue to be more reliable but again for those that want to move faster or maybe take things into their own hands there are options today and so just to dive a little bit deeper into those programs I one thing I did not mention is net metering and this is just a basically is the same as solar rewards in that you get net metering which is retail rate compensation for on-site solar but it does not include the renewable the purchase of the renewable energy credit and so traditionally in the past that purchase of the renewable energy credit was really needed to help make the the costs of the on-site solar installation work but as on-site solar installations have come down and the net metering credit stays the same it is possible and many more installations are occurring them through a net metering interconnection where's that are going to reward roughly over the past three years really roughly I want to say about one fifth of them are solo rewards residential and and the other four fist is net metering for residential installations they do yeah it's kind of net metering solar Pisani air but net metering plus solar rewards and sometimes how we put it together and then net metering on its own I mean you do you'll get net metering is kind of a baseline it's just do you want the incentive on top of that with solar rewards my understanding is that one of the drivers is that for in this kind of new ones but for residential installations for solar rewards you have to pay for the production meter which is a dollar fifty and depending on how large your system is that dollar 50 may or may not offset the payments that you're gonna get from the renewable energy credits just because the incentive has gotten so low as the cost of solar has come down so there's other than that there's a deposit that's required for solar rewards and a time frame of 12 months to get it installed versus net metering it's it's more open I mean I would suspect the customers want it they don't want to wait 12 months but there might be something there that that just yeah there's others are either selling or not taking advantage of but for our purposes were agnostic to it wind source you can go up to 100 percent of your usage it is kind of a nice program that it can kind of pancake on top of any of these other programs when it comes to solar rewards or net metering or solar rewards community there is a cap of participation of not subscribing or installing more than 120 percent of your historic usage but otherwise source and Renewable connect both can only go up to 200% sourcing that you just pay it an extra an extra small fee per a long hour or it doesn't work differently it's kind of I mean it's a it's another program and and all of these really are just an offer another choice some really wanted on on-site if so great you have solar rewards and net metering if others really looking for the financial advantage certainly in solar rewards and net metering and solar rewards community can be a piece of that but wind source is not going to offer that financial advantage it's always a premium and it's a dollar fifty per a hundred kilowatt hour Bock or 1.5 cents per kilowatt hour premium meanwhile renewable connect basically takes out the energy cost and your bills so takes out kind of the system mix cost called the more or less it's the energy cost adjustment and then puts in the cost of the solar power purchase agreement and in that depending on the energy costs of the system you may or may not save but it is a bit of a pre hedge because that PPA cost is fixed yeah wondering how the main source is priced because if the cost of your simple energy credits is coming down why is it is something that we dropped and had to get PUC approval to decrease in 2000 basically you know finally in 2017 that led to 2000 2016 into 2017 and beyond so it was dropped but it is kind of the structure of it and what we have been approved to do is through market-based pricing as opposed to kind of more what the cost causation so there are some it's not directly tied to specific wind farms but it is helping to fund wind farms that have been around for for many years and so that is yeah but the reality is they're they're relatively separate that it's kind of the pricing that we've come up with the stakeholders and the Commission has approved is really what is that market price to buy basically renewable energy credits in other forums that can similarly questions so with that if it wasn't implied we can kind of bucket those two things these different programs into two buckets one is on-site and one is more of a subscription that is whether it's in your community in the past and and to date the solar Gardens are in adjacent counties to where you you live or for your businesses where the business servers are located moving forward those solar Gardens don't have to be in adjacent counties but with that those subscription-based programs are something that aren't on-site but are for the most part they're they're all in Colorado there are the on-site programs as well that I mentioned the nuances of solar rewards and net metering and the one thing that's not necessarily a program and also isn't directly renewable but is battery storage and we're seeing more of that perhaps not surprising if you're tracking some of the energy news there are now roughly about 375 bat residential battery installations in our territory with another hundred or so in the hopper to be installed in the next 12 months or so and that's up from a lot of behind the meter batteries that were really only for backup in 2016 and before one of the big changes there is that we worked with stakeholders to figure out a way to allow the batteries to operate in parallel with a grid traditionally and this goes for solar too if the bat the grid goes down the solar actually won't keep the lights on and so in the past before 2017 if you had batteries in your home you could really only use them when the grid went down which is a great time to use them so you can still have lights on you in your own home but what that doesn't provide is an opportunity for any rate arbitrage or maybe utilizing that solar power through the batteries and then into the home as the solar production fluctuates and maybe you want to use those solar electrons in evening when you otherwise would be pumping it back on or basically pulling energy from the grid we do have a bad battery pilot in the works that is more of a program it is like I said less from a renewable perspective and more from an energy efficiency demand response perspective where we're looking to manage that battery and call on it to either reduce or curtail usage in the home when when it's needed and so that is something that will be coming out soon same thing with an electric vehicle demand side management demand response program so then you drive with this pilot program to put that power up and use it when needed so do not be you know hard to send backup for the user would be kind of the benefit of the grid and community and yes and there is an incentive associated with that so I don't know off the top my head of exactly what they are but there's both it and it's sentient to participate in the pilot and also basically for kind of allowing access to pull energy from that battery and put it into the home or at least reduce the impact of the grid there's an incentive for me calling those events it's a good question I mean that's something I know there are product developments where developers were kind of working through to to figure out how to justify it I mean I know the idea is to have it be really compensating for the value that it's providing but to simplify it and sometimes there's a balance of of art and science there that's residential focus today surprisingly surprising to me a lot of the batteries that have been installed are residential and that's I guess surprising to me in part because for the most part our million-plus customers residential customers here in Colorado pay I don't know 11 or sent the so cents per kilowatt hour no matter the time of day there is a rate pilot and a rate trial that are going on for more time of use rates that have different costs per hour with that as you mentioned of like two to six on peak time period is higher costs and that's where maybe there is some value of pulling from the grid at certain times fill your battery and letting it out at different times but yeah and that's why I think it's somewhat surprising that I mean I think there is an opportunity for batteries to provide for the individual customers which then reflects on the grid as well but at least for customers that demand charge reduction or curtailing so I don't know if I name exactly Twp from the beginning but I think I alluded to these many and this is a ni chart for sure the fact that third a lot of different customers that want different things some of them don't want to deal with programs they just want to turn the lights on and pay their bill each month and as simple as that others when it comes to renewables may want the financial benefit they may want the renewable energy credits for marketing purposes they may want to work with Xcel Energy they may not want to work with Xcel Energy and so from these different programs this is a table we put together there's also a rate advisor that's more interactive and that you can kind of go through a couple of questions that helps guide you to one of these programs but it is something I think as we've thought about the renewable portfolio and renewable program portfolio is trying to have a mix of all these different offerings to meet the needs of different customers I'm gonna shift gears a little bit no pun intended with electric vehicles but anymore I mean I can come back to two renewables but did want to talk a little bit about electric vehicles as well as a emerging opportunity for clean energy so with this I think this needs to be updated again there are well more than 525 models that are available in the US you can see some of the different pricing I think some of this may be with this room don't need to spell too many myths about electric vehicles but there are absolutely some expensive ones that are six figures plus but there are also some more affordable ones that are in the $20,000 range certainly when it comes to the including the federal tax incentive and also Colorado has one of the most generous state incentives and $5,000 yeah but I think yeah and and the electric transportation certainly is expanding whether it's from bikes certainly kind of things started out with the Tesla Roadster but also Nissan Leaf and a Nissan volt there were more sedans I think for those in Colorado that like to pack up their gear and head to the mountains it's good to see some more SUVs that can hold that capacity and I think that will provide just more access for folks that need or desire different modes of transportation and different vehicle types and so there are a handful more to add to this list but this is something that does also show there are all electric vehicles so when you see the for example that outie 8 3 there's emails plus the 550 miles of range total that is a plug-in hybrid and it will operate for 31 miles on pure electricity and then kick over to a basically a hybrid kind of working more like a traditional Prius after that - with gas a gasoline generator to take you 500 plus miles beyond that I think so the timings uncertain it may be something that starts with bigger vehicles first just from whether it's from a cost-effectiveness perspective or being able to leverage that because there are 25,000 electric vehicles in Colorado today trying to connect those all in a way that you can really call on them for a lot of energy is I think coming but is some of the thing to work out yeah yeah a true I think the I forget what the the ratio is off the top of my hand of kind of kilowatt hours to range but I think that old older Nissan Leaf that I have is a 107 miles I think that's a 16 kilowatt hour battery so that's silly yeah that's a Reno son the French government has on the first generation that really adaptors of the leaf and said all right you got the cheap battery now we need batteries much better who buy your old battery so that they created a market for youth batteries and they partnered with the base of windmills all over the place and because it might not drive car as good as the new generation of batteries do but they're perfectly usable perfectly you know and it's going to be playing so that everybody wins yep now they're gonna be a lot of batteries out there from the cars that will still have a lot of value in them absolutely you expect it once while you'll be blue balls you go too far off injury too much energy he's excited to success and you sentence they give me user Eve you owner for that energy the batteries for that you can get into the actual charger and control that so when was a 2013 so one thing is for air conditioning is a relatively large load during our peak times and those that don't know there's a saver switch and now a smart thermostat program to help to curtail some of that usage and there's an incentive to provide that just to send a signal to the air conditioner and turn it off or throttle it on and off during peak periods and that's kind of just one-way communication and it even to that end the saver switch is literally one way communication to the air conditioner in the box that's controlling it smart thermostats give one-way communication to the thermostat and then we also know is it actually being turned off so that's kind of I don't know related to vehicles I would call that for vehicles is v1g is one-way communication between the vehicle in the grid then there's v2g which is whether it's communication or also that flow of energy going both ways and right now from technology perspective we did trial kind of that throttling on-and-off thermos are startling off on and off smart Chargers and about 2014 and 15 we are embarking on kind of a new evolution of that to communicate directly with the car as opposed to the electric vehicle charger to do that just one way v1g communication with incentives to charge at different times in charge later in the evening I do think at one point there's yeah I need an opportunity to youtube to both communicate and pull from the car and I think it's coming me the technology they a little bit might be some kind of increased collaboration both with consumers utilities and the vehicle manufacturers because it's in some cases I think they have a an even though they sell the car to the homeowner they want to make sure that that battery can live up to its warranty so there's some things to work out there but it's it's gonna yes that's I think I think that's a big piece in my mind if they're more comfortable with that helps the consumers get on board with it as well I mean conceptually it at least seems like you're pulling and adding to the battery all day long while you're driving and charging so what's the difference but there I don't know it may increase the amount of of charging and discharging in addition to your driving bu
I think we're getting larger batteries 200-plus miles of range is I know if I call it standard yet but certainly more affordable and many consumer vehicles and so that longer range may provide some more flexibility both to get to work but also maybe leverage it for the grid we can anticipate that your dad we get renewables forecast might be available to your customers that's out of my scope of yeah I think of when that's coming and I couldn't tell you what the barriers are to that I know I mean hourly in real time there's some kind of market transparency tech things there that I think maybe some issues with but I mean most people United States yeah I don't know but I'm at I think I've at least thought of it before from I don't know I think as we think about traditionally I mean economics certainly drive quite a bit of either individual decisions or business decisions and so a lot of it has been kind of decisions have been based on what's the cost of the energy at different times a day or in a broader perspective but as we do look forward I know we'll be driving to more carbon carbon free solutions and kind of aligning carbon free with the cost to consumers I would anticipate more of that to help kind of line those up and head together in the right direction so as I mentioned a lot more electric vehicle models available and then also many many more chargers that are available for the most part today most charging happens at home 80% plus but on at the same time there are 750 plus public chargers in our territory those green dots on the map this is from plug share but there are other maps are level I think mostly level 2 but some level one chargers that'll charge at about 3 to 6 miles of range per hour the orange dots are faster chargers that'll take about a half hour an hour to charge your vehicle depending on how much range you have in your vehicle don't you think hotels and restaurants are gonna gate religions and they're just gonna start everywhere yeah I mean there and there I mean some of this is to show that they're there in more places than you know if they're just kind of hidden but I think one of the questions for us as utility is is one is how fast our electric vehicle is gonna come in general and then the other is our most people gonna charge slowly at home for the most part evening and then or is it going to become more of a gas station type scenario and kind of in between there is I don't know destination charging at hotels or more convenience locations I mean I know that yeah yeah there there sure and some of that I mean is a function of as we know I mean Tesla was was sold out 24 hundred plus thousand cars before they even made a handful of them I think they've caught up for the most part of this overall I'm supers he's cost the cost it's just the cars there's only so many people that buy a new car period no matter the price but no chops off a certain percentage of probably a big percentage then there's a chunk that don't have cars at all but then there are some folks that maybe you're gonna buy used cars because they're just more affordable and more in their price range and as I mean V's have been around for the mass market for five plus years now some of those are turning over and becoming more accessible to that other market of abused car buyers that I think will help get more and more on the road and and some of those folks that have purchased new ones are continuing to stay with electric vehicles but yeah I don't know if there is really a bottleneck I mean it's not a perfect kind of alignment of manufacturing customer demand prices but it's it's it's a whole lot better than it was actually varies per storage unit is yeah there is I mean we're about to embark on that federal tax credit that I mentioned is 75 up to seventy five hundred dollars based on the battery size it's a federal tax credit one also related to kind of cost and accessibility it you need a tax appetite to take advantage of that so that's not something everybody has but the other piece of it is that expires for manufacturers that have sold two hundred plus thousand vehicles Tesla's there or getting there really soon I think Nissan Chevy R as well and so that'll be interesting to see how that plays out with some of the laggards that maybe you have only sold ten thousand vehicles but have kind of followed and are trailing those as far as a technology perspective that may be able to leverage the lessons learned from the early manufacturers and accelerate things quite a bit there is a leaf incentive it is paid for by Nissan actually is the one that pays for it but it is for Xcel Energy customers that we are yeah hoping to get the word out about that so there's a I think it's thirty five hundred dollars for a new leaf so yeah so there are some decent incentives out there while the costs of the vehicles come down to we are yeah basically every sedan that's been retired or will be retired will be converted to a plug-in electric vehicle there's I think about thirty five electric vehicles in the fleet today we also have some bucket trucks that are electric power take-off modeled I think that's the other thing some of our fleet is larger trucks and so whether it's off the US or other utilities across the country or even municipalities that have larger trucks but decent sized fleets there's an opportunity there and I think we talk a lot about consumer vehicles but certainly those trucks are an opportunity buses and public transit as well can'tcan't free other bikes do yeah charging that takes place at home is that mostly level one just plugging into the wall or do you have any idea there's what the percent of use of level 2 charging is we do we've done some surveys ourselves and I think in the early days and just the response rate wasn't a huge number that we could be like okay this is really the trend but I mean it's really roughly about half and half probably with a little bit more biased towards level ones today I don't know if that'll change with longer range vehicles as I don't people maybe end up driving more because I mean for the most part those I don't know the the early leaf that was 84 miles of range you could charge that overnight 107 miles I know for mine depending on if I really drained a double the way down and I'm just putting charging on level one depending on when I start charging in it and and I might not charge all the way up in a level one and so there's there's some things that play there which i think is part of that big question of how fast do people really want to charge and and or a need to whether it is that's super fast or fast chargers in public or even the difference between level 1 and level 2 so so we installed our level 2 charger at home six six and a half years ago and at that time there was a rebate from the state highway that virtually covered the cost plus insulation you know this $800 and I think the total was a lot of effort to do that and we now have an S Plus and I'm getting two hundred and seventy miles of range or something that really I love and it takes six hours on the level tube to go from the up teamed so six hours per to 70 yeah that's right I mean he'd be a great 2:26 reliably getting even in this colder weather to 60 to 70 miles of range that's a 64 and that pilot that we're developing and launching soon is for level two Chargers only part of that I think is the level one is a relatively small drawn on our system certainly an aggregate it gets big but I think to provide that larger and incentive and benefit we're also looking to curtail more or at least shift more into the evenings level one is 120 the level two is 240 yeah yeah and roughly two times the speed and to that end I mean we talked about the cost of the vehicles what we're not most interested in but a big piece of the equation for us is the cost of electricity and as you can see here electricity has been pretty flat and stable over the past two decades almost that it's about $1 per gasoline gallon equivalent meanwhile wall gasoline goes up and down I actually don't know what we're at right now because I drive an electric vehicle and won't pay attention to it anymore but I think it's somewhere between two and three bucks but yeah it is interesting I think even thinking of that I think what do you think of energy and kilowatt hours many folks don't know what that is and sometimes in the past I've equated that to gasoline of many people are more versed in what a gallon of gasoline is as well as what the cost of gasoline is at that point in time you asked the public what the cost of kilowatt hour I think he'd you get a wide range of prices from from reality to too many dollars per kilowatt hour which isn't real and and I don't know I guess over time I've also I'm not paying as much attention to gasoline and have no idea I mentioned the residential rates so there is a pricing to pricing pilots the time-of-use pricing and peak demand pricing this is for residential this is something that we've been exploring for the past two or so years and the time-of-use pricing does have basically to 2:00 to 6:00 p.m. is during the weekdays is our peak period and that's a higher price than the off-peak periods which is outside of the windows of 9:00 p.m. and 9:00 a.m. and then in between there there are two shoulder prices that so there is more of a dynamic pricing based on when use that electricity the peak demand is a as the maybe name implies for those that are savvy to demand charges does have a demand charge and then also time of use more energy per kilowatt hour charge to it and so that's between 2:00 to 6:00 p.m. if you you really want to try to stagger your usage between I don't know your air conditioner and your refrigerate well air conditioner electric dryer and charging your electric vehicle try to stagger those and keep them kind of more flat line than the new plug in them all at once you're good ok and then otherwise we have the general default residential plan that's something I think we've been more trishla traditionally accustomed to is that more fixed price over the course of the day in this summertime there are tears and when you use more than 500 kilowatt hours per month that are higher in price for that increase above 500 kilowatt hours marketing this is a population you know the toriel has so much money they can save time on user peek if they are willing to charge their vehicle at night yeah it's just significant I should put it something like a neat user video device just not the way Drive and sure how much you know how much your adoption is but you should be hundred percent right yeah there are some I mean I agree there are some folks that made me work from home that have a lot going on in the home during the day that maybe won't be offset with electric vehicles but for the most part it makes it really easy and encourages you to charge at night and and drive for that much cheaper I mentioned the renewable energy program advisor I think is about five questions that it guides you through on your personal preferences it is a little bit residential or it is residential focused help you think through your your renewable program options between wind source renewable connect solar rewards net metering and also the solar garden program we also do have a relatively new electric vehicle advisor and so that's at Xcel Energy calm /vv pretty easy and it's something that helps guide you to a different models and certainly some of those questions are about preferences about cost savings or your budget but even just lifestyle things and I think that gets to that portfolio of different vehicles that are available is there are different models some folks really need four doors or even a minivan and there are those options available today and then also energy efficiency rebate finder just makes it easier to find the plethora of options that are available for that 150 renewable energy programs so trying to make it easier I know my team customer calls and our kind of a not consider them then the Navy SEALs of customer care to really answer the most complex solar questions you might get but at the same time kind of for more than just an introduction and reading through information on our website these tools make it easy to look at your options did you make you have a commercial equivalent to the page she just showed us before like yeah just kind of being for the question don't ask about see you and the commercial one industrial users this is definitely thing here one segment of your breakers store and there are options for businesses I mean I think there are for the most part they go to the default options that are available but there are some different options with a solar PV solar or solar time of use rate specific for solar customers there is a low load factor rate SGL for those that maybe have more intermittent usage that spikes infrequently and so there are options there that I agree I think I don't know if we communicate as well as we could from California forward the midnight rate is four times cheaper than five yeah you're talking about the the time-of-use pricing yeah yeah so that's yeah it's about double the peak demand gets a little more complex because it does have a demand charge but the off-peak prices I think about three cents per kilowatt hour and then I don't want to guess at the the other kilowatt hour charge but it does have a fifteen dollar demand charge in the summers between the distribution and transmission charges but it kind of it's a little we from visually and some of the information our website's been hard to kind of compare apples to apples there because it does have kilowatt hours versus kilowatts but yeah I think for those that are more comfortable with the volumetric its yeah roughly eight cents to 18 on the time-of-use pricing roughly about 12,000 it's a voluntary pilot and it's voluntary so roughly 7,000 on the time of use and 5,000 on the peak demand really roughly kind of in that general direction also I tell every single one that customers don't abuse because the higher peak times are during the day and at night other analytics and I can design my systems at 80% actual actual offset and then on top typically consume consumption throughout the day I think the people would just make the change generally they're lunch options they dial into the fact that they're just not one more page on the planet now I'm interested in the capital picture so you talked about the early retirement of Comanche wanted to with that - the only strand assets that you see to meet the 80 percent by 2030 so I don't I don't know if I'd call them stranded but there definitely will be some fossil fuel retirements period and I think the ideal and as we look at the 80 percent reduction by 2030 it's in 10 years time relatively quick for a lot of energy a lot of capital and a lot of vestments that are out there I think the plan to get there is through a lot of renewables it may be through natural gas and other energy storage we don't have nuclear here in Colorado energy efficiency but there is also both retiring coal plants as well as kind of throttling and managed the usage of some of those fossil fuel plants as little as we can there is also the strategic electrification aspects of things when it comes to electric vehicles that may provide some benefit of balancing the system and then at the same time there's a lot needed to invest in the grid both from a communications perspective as well as from the equipment to be able to manage this either intermittent power flow or sometimes reverse power flow so to answer try to answer at least a little bit of your question over the next 10 years will be some retirements as well as just reduce use and operations of fossil facilities after that that lasts to 20% we really need to find some technology solutions to be able to turn them all the way off you'll see dramatic changes those next 10 years to build up the reading levels and/or retire existing generation early I mean they'll have to be capital outlays to build these wind and solar farms for sure I think some of the terminology and ideal is we're investing in steel for fuel ones so instead of investing in the the feel the natural gas or the coal it's investing in the the steel of end of t
e the solar facilities and also that wind turbines and so to that end money will have to be spent but as the costs come down I think that's really one of the biggest phenomenons that helped us make makes this work is that the renewable energy costs have come down that it becomes economic to to make these investments in and cleaner energy um so I want to look at that list the one guy resonates with me seasonal storage whatever that means whatever the costs are actually attendance is aspirational but that could sort of right by itself get rid of that 8 to 1 ratio sir yeah oh yeah no I mean absolutely like I said those are the bookends we got to bring it into reality and some of that yeah kind of what seasonal storage is today I don't know if current technology gets us all or a current technology does not get us all the way there and so that's where some innovation needs that to occur and certainly those smart minds of the folks here at CU we need your your help we need some collaboration with labs to continue to help find solutions to get to that last 20% versus decarbonizing your electricity supply sure I think that's what one this is really for the electric system as it is today as opposed to the natural gas system but I think that's coming as well and is another kind of piece of that strategic electrification it's gonna be a big lift for residential conversions but I think there's some probably specific targets target markets so you can hit to do some of the later even just new construction and start from electric begin with but retrofits are I didn't just think logistically are gonna be a challenge both for consumers and then certainly utilities adapting gas utilities adapting to that that decreased load or yeah yeah there and I think some of the analysis so far kind of is again one of those extremes and bookends but it would be if everybody went electric today would be doubling the electric load our electric from natural gas that is so that would be also a big lift too so there is kind of the shifting away from from natural gas for heating and then also building the electric system to be able to solve for that do you think the goal for Colorado should be added 20% 50% just because our resource is better than many of the adjacent states does excel has a pathway to actually become an energy exporter it's a good question I mean I think there might be market changes to make that happen I'm sure there would be had to be market changes to make that happen but I mean if the most part we're really working on the hundred percent carbon free today and our that's that's our eyes on the prize is the hundred percent carbon free as opposed to going further and exporting it more a big piece of a big piece of a small regulated business is our home smart program and that's something that provides maintenance and service on your your home appliances from many different things from your refrigerator to your your furnace and air conditioner that is something that we're looking to build up to provide some of that more in-home services because it is one thing for us to to make improvements to the grid and to the generation systems but it's another to kind of line that up with both renewable our energy efficiency programs as well as just efficient equipment with that just to wrap it up and again I'm happy to answer more questions I think there's a little bit of time but we are working on the carbon emissions is number one with that we have to keep in mind reliability the system and affordability and it will be important to get alignment with States and stakeholders when it comes to the constructive public policy to help make that happen and then also really that the technologies for 24/7 365 carbon free delivery of energy by 2050 is going to take a lot of work a lot of collaboration new ideas and some of it needs to start today and we don't have the answers today so welcome those ideas and continue to work thank you brought this up in one of them the use had a program that we call seeds of their creation program to lets areas of interest certainly for these values not a zone from the indifference art designer from the you know during of their power supply through contracts and so forth and then speaking with one of the people of the champion and they mentioned the Community Choice Energy legislative effort or something along a line in Colorado I was wondering could speak to either of those programs I can't speak to the the legislation or in just kind of the policy overall but I know we are increasingly engaging in conversations with with communities as a whole and one of those efforts is something called partners in energy and there's also a energy futures collaborative but one of the the partners in energy one piece of that is to sit down with the communities and those communities could be a city it could be a County but is to sit down with them and understand what their goals really are and what are some of the metrics that they're looking for it maybe is starting to head in the same direction but in some cases some communities have 100 percent renewables goals some of them have energy efficiency reduction goals some of them have kind of broader sustainability goals and trying to figure out we we operate in a world for the most part of kilowatt hours and and therms and increasingly carbon metrics but how does that line up with some of the other efforts that they're looking to for their goals and that's something we've helped to fund kind of collaborative projects from the consulting work and then also strategic planning to identify ok how does how do our existing energy efficiency programs line up to help with those goals of whatever they may be or renewables as well the other thing I think is with the energy futures collaboratives is really taking that even further and just continuing that conversation to understand is it are those goals just for citizens is it just for the buildings with that are served or owned by the community or a mix of all of it and how does that fit in how does a community influence its citizens it's one thing to influence their own and make their own building decisions but it's another to influence decisions so we're having those conversations I think to help understand a little bit how how do the programs we had today line up with that and how do we develop programs in the future that can align with them and a broader scale to serve many customers not just kind of one by one but but as a whole so another question a few months ago we had a presentation here by Byron Jackson garden that presentation is on the web it's under it's on the crash site under the video link so if that's of interest to you that's probably place you should go check it out maybe one more and then I'm happy to chat 101 thereafter but broadly and I'm not sure if you pass you think even a lot of color but how a regulated market versus a wholesale market like an earth cop or something like that do you see those structures like encouraging more build-out over noodles or do you think regulated utilities that that is which contributes more which Spurs more bills out or that's kind of affecting factor blazing-hot anything sure I think I mean one is I wish I knew a whole lot more about kind of the the unregulated markets but the just markets in general I personally wish I knew more about it so I'm not very well-versed I mean I think you'd hear from our executives and for myself I mean they vertically integrated regulated utility things can seem slow but you can make huge moves I mean this 1,100 megawatts of wind 700 megawatts of solar that's pretty big and pretty fast and so I think I'd argue for the advantages of of the regulated utility there's some transparency to it there's I think some some rigor to trying to balance all the different stakeholder input because we're serving all customers and need to balance all those interests and energy is critical to our society our economy and I think it's important to balance all that as you scroll backwards through your slides when you're very very ones you had an image of today and then the 80% view which years they do market our deficits yes one last plug I didn't stand up maybe should have but we are hiring and I'm specifically hiring for a mark to marketing assistance contractor roles for our solar rewards team they interact a lot with the solar developers both gardens and on-site solar great experience to to get a feel for the whole market here in Colorado or at least the Xcel Energy piece of the market so if you have any friends colleagues family is please send in my way with that you know the chat with you one-on-one
