Questions homeowners ask
What is the announced 2026 one-time transfer window?

Is there a minimum balance or unlimited transfer requests?

What does the utility recommend reviewing before a request?
Review and update applicable Schedule Z or AOBC credit allocations as needed. The notice says transfer requests must follow the relevant incentive program rules.

Where does the one-time request go?
The notice links a transfer form and worksheet for submission through its Contact Us feature. A Solar Specialist reviews the request; submission alone is not confirmation of processing.

Which net metering provision was reviewed for this guide?
MDPU 1625, effective March 1, 2026, replaces MDPU 1598. Retain the provision applicable to your account and the utility’s written classification.

Does every solar facility receive the same credit calculation?
No. The provision distinguishes Standard, Market and other credit calculations by facility classification. Its appendices map categories to calculation components. Confirm yours instead of assuming a universal retail-value credit.

What record supports an allocation question?
Section 1.07(9) assigns the utility responsibility for accurately allocating net metering credits consistent with the host customer’s Schedule Z designation. Retain that designation and affected bills.

Does the utility tariff resolve every disagreement between people receiving credits?
No. Section 1.11 addresses tariff disputes between the utility and host customer, including allocation accuracy. It excludes utility responsibility for disputes between the host and credit recipients.

How should I build a private credit-transfer record?
Record the starting balance, intended accounts, submitted documents, submission date, reference number and written response. Compare later bills with that response and record any discrepancy. Keep account numbers and bills private. Ask the utility to explain missing or rejected items before assuming that a balance moved. This worksheet is editorial organization advice, not a substitute for the official forms.
How does Solar Survey AI help frame a homeowner decision?
Our education and evidence methodology help separate observations, assumptions and unresolved questions. Contact us to confirm an available survey scope for the property. A survey does not process utility credit transfers, classify your tariff or guarantee an incentive. Homeowner provider connections and free remote diagnosis remain coming soon.

Trace the balance from request to bill
| Record | What to retain |
|---|---|
| Account and program | Electric utility, accepted program and tariff classification |
| Opening balance | Bill date, units and balance before the request |
| Allocation record | Current designation and any requested revision |
| Submission | Completed official documents, date and reference number |
| Utility response | Reviewed arrangement, decision and expected processing |
| Reconciliation | Later bill entries, unresolved difference and responsible contact |
Example: an owner preparing to sell a home has an accumulated balance. Keep the proposed account arrangement separate from the property-sale documents. Ask the utility to review eligibility and processing before representing the balance as transferred. A buyer’s expectation is not written utility confirmation.
Example: an installer’s forecast combines several anticipated benefits into one annual dollar total. Ask for separate program assumptions, an applicable credit calculation and a version showing unconfirmed benefits separately. Keep forecast figures apart from actual billed credits and payments.
This selected guide concerns National Grid Massachusetts electric accounts. It does not establish rules for Eversource, Unitil, municipal utilities or National Grid in other states. The one-time exception is dated 2026; do not assume it continues in a later year. Confirm current account applicability and program restrictions directly with National Grid. We do not provide a complete tariff calculation or legal advice. Continue with electricity bill comparisons, buying and selling solar homes and proposal and finance records. Explore Solar Survey AI’s evidence methodology and confirm relevant survey scope. No credit transfer, financial outcome or utility approval is guaranteed.
