Start Service with National Grid in Massachusetts (2026)

The boxes are still stacked by the door, the WiFi isn't connected yet, and the landlord just texted asking if utilities are in your name. Signing up for electricity feels like a five-minute errand, so most people knock it out fast and move on.

That's fine. National Grid's online enrollment genuinely is quick. But buried inside that quick form is a default supply rate you'll stay on until you actively change it. Understanding what that rate is, and whether something better is available, takes about the same amount of time as making coffee. This guide covers both.

National Grid is one of two major electric utilities in Massachusetts. It serves a large portion of central and eastern Massachusetts, including Worcester, Lowell, Springfield, and a stretch of communities north and south of Boston. It also serves Nantucket under a separate rate structure.

Eversource is the other major utility and covers a different footprint, including Boston proper and the western part of the state. Your utility is determined by your address, not by choice. If you're moving to a new address and aren't sure which company serves it, check the Massachusetts electricity guide or call National Grid directly. The address lookup on their website will confirm service territory instantly.

National Grid allows new customers to start service online, by phone, or, in some cases, through their mobile app. Online is the fastest path for most people.

What you'll need before you start:

Your new service address. The date you want service to begin (usually your move-in date or the day after your lease starts). Your Social Security number or ITIN for identity verification. A payment method, since National Grid may require a deposit from customers without an established credit history.

Steps to enroll:

1. Go to nationalgridus.com and select "Start Service" under the Massachusetts residential section.
2. Enter your service address to confirm it falls in their territory.
3. Provide your requested start date. National Grid typically needs at least one business day's notice, so plan accordingly if you're moving on a weekend.
4. Complete identity and contact information. If a deposit is required, you'll see the amount before you finalize.
5. Set up your online account for billing and future usage tracking.

Once the account is active, National Grid handles meter reading and delivery. You don't need to schedule an appointment for most standard activations. If the meter at your new address needs to be physically turned on (common in vacant units), they'll note that and arrange access.

When you start service with National Grid, your electricity supply automatically goes on Basic Service, the utility's default supply rate set by the Massachusetts Department of Public Utilities (DPU). As of July 2026, National Grid's Basic Service rate is approximately 15.4 cents per kWh.

Basic Service is not a penalty rate. It's a regulated, averaged rate the utility procures through competitive bidding on behalf of customers who haven't chosen a third-party supplier. It changes periodically, usually every six months.

For context, Eversource's Basic Service rate is approximately 15.6 cents per kWh as of July 2026. National Grid on Nantucket sits at approximately 15.4 cents per kWh as well. The supply charge is only one component of your total bill. Delivery charges, which cover the poles, wires, and infrastructure that physically bring power to your home, are separate and set by the DPU regardless of which supplier you use.

Massachusetts has a competitive electricity market, meaning you can choose a third-party supplier for the supply portion of your bill while National Grid continues to handle delivery. This is sometimes called "retail choice."

As of July 2026, the lowest competitive supplier rates available in Massachusetts are around 15.1 cents per kWh, depending on your utility territory and the specific offer. That's a modest but real difference from National Grid's 15.4 cent Basic Service rate. Whether it's worth switching depends on the contract terms, any fees, and how long you plan to stay.

The state's official comparison tool, Energy Switch Massachusetts, lists licensed competitive suppliers and their current offers. It's run by the state, not by a supplier, so the listings are neutral. You can also compare options at ElectricRates.org's Massachusetts page for current live rates.

A few things to watch when comparing: fixed-rate contracts lock your supply cost for a set term (often 6 or 12 months), while variable-rate offers can swing month to month. Some suppliers advertise renewable or green energy options at a slight premium. Always check whether an offer has an early-termination fee before signing.

National Grid, like most utilities, may run a credit check or request a deposit for new customers without an established payment history with them. The deposit amount varies based on your credit profile. If a deposit is required, you'll see it disclosed before you complete enrollment online.

Deposits are typically returned, with interest, after a set period of on-time payments. If you believe a deposit was incorrectly required or the amount seems disproportionate, the DPU is the regulatory body that handles complaints and disputes related to Massachusetts utilities.

Your first bill may cover a partial month if your service start date doesn't align with National Grid's billing cycle for that address. Don't be alarmed if the first statement looks different from what you expected. The account summary page in your online portal breaks down delivery and supply charges separately, which helps you verify that Basic Service rate is correctly applied.

If cost is a concern at move-in, Massachusetts has several programs that can reduce your electricity bill significantly.

LIHEAP (Low Income Home Energy Assistance Program) provides federally funded assistance for heating costs and, in some cases, electric bills. Eligibility and benefit amounts are based on household income and size. Applications typically open in the fall for the heating season, but emergency assistance may be available year-round. Check with your local community action agency or visit the state LIHEAP page for current eligibility thresholds.

National Grid's low-income discount program offers reduced delivery rates for qualifying customers. Enrollment details are available directly through National Grid or through community organizations.

Applying for these programs doesn't affect your ability to compare suppliers or change your supply source later.

Nantucket is served by National Grid under a separate rate tariff. The Basic Service supply rate as of July 2026 is approximately 15.4 cents per kWh, the same as the mainland rate. The enrollment process is the same: start online through nationalgridus.com, selecting the Massachusetts residential option.

Because Nantucket's grid has some unique infrastructure considerations, customers there may want to confirm any questions about outage response or specific rate riders directly with National Grid's Nantucket service team.

Start service at nationalgridus.com as soon as you have your move-in date, ideally a few days in advance. Set up your online account so you can track usage from day one. You'll land on Basic Service at approximately 15.4 cents per kWh, which is reasonable, but check Energy Switch Massachusetts or ElectricRats.org for current competitive offers before your first full bill cycle closes. If you qualify for assistance programs, apply early. And if anything looks off on your first statement, the DPU is your regulatory backstop for billing disputes.

That's it. The process isn't complicated, and making a deliberate choice now, rather than defaulting to inaction, puts you in control of one of the few recurring costs you can actually influence in a new home.
