Can an ISA be signed electronically?

Yes. Electronic signatures are generally enforceable under the federal ESIGN Act (15 U.S.C. ch. 96) and UETA in most states, provided intent, consent, attribution, and retention requirements are met.

When is notarization required?

Notarization depends on state and the specific exhibit. If state law or a recording requirement applies, notarize signatures as required by the relevant state recorder or utility regulation.

Who should sign on behalf of a company?

An officer or authorized representative with corporate authority should sign. If required, attach a corporate resolution or power of attorney proving signing authority.

How do you amend an executed ISA?

Amendments should be in writing, signed by authorized representatives of all parties, and reference the original ISA by date and parties to avoid ambiguity.

How long must records be kept?

Retain executed ISAs and supporting records for the term plus statutory retention periods; follow IRS rules (IRC §6501(a)) and industry-specific retention like HIPAA where applicable.

What if parties disagree after signing?

Use the dispute-resolution clause in the ISA (mediation, arbitration, or litigation), preserve evidence, and consult counsel to avoid waiving contractual or regulatory rights.

What an Interconnection Service Agreement Covers

An Interconnection Service Agreement (ISA) sets the technical, commercial and operational terms for connecting an electrical or communications facility to a host network. It establishes responsibilities for construction, testing, metering, protection, and ongoing operation, and allocates costs, revenue treatment, and liability between the connecting party and the network owner or operator. ISAs are used for distributed energy resources, utility-scale generation, telecom carrier handoffs, and other systems where two networks must exchange power or signals while protecting safety and reliability.

Why an ISA Matters for Connection Projects

A clearly drafted ISA reduces operational risk, defines who pays for upgrades, and documents timelines and performance standards. It creates enforceable expectations for commissioning, maintenance, and outage coordination while preserving remedies for nonperformance.

Typical parties and users of an ISA

Each signer should have authority to bind its organization and be prepared to accept technical and financial obligations described in the agreement.

Distributed resource owners and developers responsible for the new facility and interconnection work.
Utilities, independent system operators (ISOs), or network operators that receive the connection and manage grid/ network access.
Engineering, procurement and construction (EPC) contractors and vendors who execute equipment installation and testing.

Core sections to include in a professional ISA

A complete ISA addresses legal, technical, financial and operational topics so parties can connect safely and predictably.

Parties & Definitions

Names of contracting entities, defined terms, contact information, and any affiliate or billing party designations used throughout the agreement.

Technical Specifications

Detailed electrical or network connection requirements, interconnection point drawings, protection settings, metering requirements, and site equipment design standards.

Interconnection Facilities

Allocation of construction responsibility, ownership transfer points, testing procedures, commissioning criteria, and acceptance protocols for interconnection equipment.

Operational Procedures

Coordination on outages, switching, emergency operations, curtailment procedures, telemetry and data-sharing obligations between parties.

Financial Terms

Cost allocation, invoicing schedule, security deposits, payment terms, responsibility for upgrade costs, and any applicable tariffs or rate schedules.

Liability & Termination

Indemnity frameworks, limitation of liability, insurance requirements, events of default, termination rights, and post-termination obligations.

Essential data fields to collect

Legal Name: Full registered entity name

Contact Information: Street address and email

Interconnection Point: Specific physical or network connection location

Capacity Rating: Maximum MW or bandwidth

Metering Details: Meter ID and configuration

Insurance Limits: Policy types and minimum coverages

Step-by-step: Completing the Interconnection Service Agreement

Follow these steps to assemble required information, complete fields, obtain approvals, and execute the ISA with proper authentication.

01

Gather documents: Collect site plans, equipment specs, and permits
02

Populate agreement: Enter party details, technical data, and schedule
03

Internal review: Get legal and engineering sign-off before finalizing
04

Execution: Sign, notarize if required, and exchange fully executed copies

Configuring the online completion workflow

Set up a digital routing workflow that matches your approval and signing sequence before you send the ISA for signatures.

Field	Configuration
Authentication	Email link or SMS code for signer identity
Signature Type	Choose electronic signature or digital PKI signature
Routing Order	Specify signers and sequential or parallel flow
File Format	Use PDF/A for long-term preservation

Where to submit and what happens next

After execution, send the signed ISA to the network operator and retain copies per your records policy.

To the Utility: Submit executed agreement to the utility interconnection team
Permitting Agencies: Provide required copies to local permitting authorities
Internal Records: Store signed ISA in contract repository and project folder
Commissioning Team: Share executed technical exhibits with commissioning engineers

Digital signing and distribution considerations

Ensure the chosen platform can produce a tamper-evident, timestamped audit trail and meet any HIPAA or regulatory requirements applicable to your project.

Supported formats: PDF, Word DOCX, and printable PDFs
Integrations: Connect to Salesforce, NetSuite, and Google Workspace
Security: TLS in transit and AES-256 at rest

Common timelines and processing expectations

Typical ISAs include submission windows, technical review periods, and commissioning milestones—plan for administrative and engineering lead time.

Application Submission:

Submit all forms and exhibits before initial review begins

Technical Review Period:

Allow several weeks to months depending on system complexity

Construction Schedule:

Specify start and completion dates for interconnection work

Commissioning Window:

Provide dates for testing and acceptance activities

Operational Handover:

Deliver final documentation and meter data to utility

Common mistakes that delay interconnection

Incomplete technical exhibits or missing single-line diagrams cause engineering rework
Incorrect party names or signer authority lead to execution delays
Omitted metering or telemetry specifications create billing disputes
Unclear cost allocation for upgrades results in negotiation stalls

Key risks and contractual consequences

Delay Costs: Damages and extended construction costs

Operational Loss: Curtailment or lost revenue during disputes

Liability Exposure: Third-party claims for equipment damage

Termination Risk: Agreement may be ended for breach

Regulatory Sanctions: Fines for noncompliance with grid rules

Disconnection: Forced removal of equipment for safety

Practical tips for accurate and efficient completion

Follow these practices to reduce negotiation cycles and technical rework when preparing an ISA.

Prepare exhibits early

Complete technical exhibits and single-line diagrams before contract drafting to avoid scope changes.

Clarify cost allocation

State precisely who pays for upgrades, studies, and future modifications to prevent disputes.

Confirm signer authority

Obtain corporate resolutions or signing authority documentation for entities signing on behalf of organizations.

Use auditable eSignatures

Select a platform that provides tamper evidence, timestamps, and a downloadable certificate of completion.
