Key Takeaways

Massachusetts electricity choice depends on your utility, town, and current supply arrangement. These points will help you identify your options before you sign anything.

• You may choose an individual supplier in some utility service areas.
• A municipal light plant town may limit or block outside supplier sales.
• Your utility still delivers power and handles the electric bill after a switch.
• A low advertised rate can change after a short introductory period.
• The full contract and Electricity Facts Label matter more than the headline rate.

How electricity supply works in Massachusetts

If you are asking, "can i choose my electricity supplier in massachusetts," start with your address and current bill. Massachusetts separates the electricity supply charge from delivery. Your town and utility determine whether individual supplier choice is available.

The answer is not the same for every household. You may have utility Basic Service, municipal aggregation, an individual supplier contract, or service from a municipal light plant. Check that status before comparing rates.

The difference between a supplier and your local utility

A supplier provides the electricity supply portion of your service. Your local utility owns or manages the delivery system that brings power to your home. The utility also handles outages, meters, and much of the billing process.

Your bill should help you tell these charges apart. The supply section names the current supply source or rate. The delivery section covers the local wires and related utility service.

What the utility still handles after you switch suppliers

Switching suppliers does not mean a new company sends separate wires to your home. Your utility still delivers electricity, reads the meter, and responds to delivery problems. You usually continue receiving one electric bill from that utility.

The utility also remains the place to report a power outage. A supplier change affects the supply charge, not the physical delivery of electricity.

How deregulation gives customers a choice

Massachusetts opened parts of its electricity market to competitive suppliers. That allows some customers to select a supply contract instead of staying with utility Basic Service. The choice is limited by local rules and service territory.

The Massachusetts Attorney General reported that residential customers who individually chose competitive supply paid over $738.7 million more collectively over the last decade, in its 31 March 2026 report. Those figures concern individual competitive supply contracts, not municipal aggregation.

Why electricity delivery does not change when your supplier does

The wires, meter, and local repair system stay connected to the same utility. A supplier change changes who provides the supply portion of your bill. It does not change the route electricity takes to your home.

That separation is useful when you compare offers. Look at the supply rate and contract terms while treating delivery as a separate utility charge.

Who can choose an electricity supplier

Eligibility comes before price. Your utility territory, municipality, and current enrollment decide whether you can shop for an individual supplier. A general statement that every Massachusetts resident can switch is wrong.

You can identify your situation by reading the supply section of your bill and checking your town’s electric service. If the bill shows a group municipal supply or a municipal light plant, the usual shopping rules may not apply.

Residents in areas with competitive electricity markets

Residents served by participating investor-owned utilities may be able to choose an individual competitive supplier. The available offers can depend on the address and the utility territory.

Some households are already in municipal aggregation. In that case, the town bought supply collectively and enrolled customers unless they opted out. You may still have a choice to leave, but the process and terms differ from an individual contract.

Customers served by investor-owned utilities

Eversource, National Grid, and Unitil serve many Massachusetts customers. Their customers generally see a utility Basic Service option, although a customer may also have municipal aggregation or an individual supplier contract.

The Massachusetts Department of Public Utilities publishes utility electric rates and tariffs. Use the rate for your own utility and service territory, not a statewide average.

Renters, homeowners, and people moving into a new address

Renters and homeowners can both encounter supplier choice. The account holder usually controls enrollment, but a lease or building arrangement can affect who receives and pays the bill.

When you move, ask which supply arrangement is active at the new address. Do not assume your old contract transfers. A new address may have Basic Service, aggregation, a supplier contract, or a municipal light plant.

Situations where supplier choice may not be available

Massachusetts has 41 municipal light plants serving all or part of 50 municipalities, according to the approved state information. Under Massachusetts General Laws chapter 164 section 47A, a municipal lighting plant may prohibit outside suppliers from making retail sales in its territory.

That means you may not be able to shop for an individual supplier at your address. A utility or town notice can clarify the rule before you share personal information with a salesperson.

How to compare Massachusetts electricity suppliers

Once you know that shopping is allowed, compare the whole offer. A supply rate is only one part of the contract. Term length, renewal language, credits, fees, and renewable content can change the practical value of a plan.

Your current bill gives you the starting point. Compare a new offer with the supply rate you actually pay, and use recent usage if the offer includes a credit or usage band.

Fixed-rate and variable-rate plans

A fixed-rate plan keeps the stated supply rate in place for the contract term, subject to the contract rules. A variable-rate plan can change under the supplier’s terms. A lower variable rate today can rise later.

For example, National Grid’s variable option was 15.615 cents per kWh in September 2026, while its fixed option was 17.185 cents per kWh, according to the Massachusetts Attorney General’s competitive supply information. The comparison is a snapshot, not a promise about future rates.

Contract length and renewal terms

Check how long the initial term lasts and what happens when it ends. Some contracts renew automatically. Others move you to a different rate or require a new choice.

Look for the notice period and the date by which you must cancel. A contract that looks simple on the first page may contain the key rules in a later section.

Promotional rates, introductory offers, and rate changes

A promotional rate may apply only for an opening period. It may also depend on monthly usage, paperless billing, autopay, or a bill credit. Read what happens after the promotion ends.

The EFL Decoder and the Teaser Test are useful ways to slow down a quick sales pitch. Ask what rate applies to your expected usage after every credit and introductory period is over.

Renewable energy content and other plan features

Some offers include renewable energy content or other features. Treat those details as separate from the price. Confirm how the feature is defined and whether it changes the supply rate or contract terms.

Do not let a feature distract you from the basic questions. You still need the rate, term, renewal rule, cancellation fee, and deposit requirement in writing.

How to read an electricity supply offer

A supply offer should let you find the main cost and the rules without guessing. Start with the rate, then read the conditions attached to it. The Electricity Facts Label can organize much of this information.

The Massachusetts Attorney General’s consumer page explains that customers should examine competitive supply contracts carefully. A clear offer names the supplier, term, rate type, fees, and cancellation process.

The supply rate and how it is measured

Electricity supply rates are commonly shown in cents per kilowatt-hour. Your monthly supply charge depends on the rate and the amount of electricity used. Delivery charges are separate.

As a reference, Basic Service residential rates from August 1, 2026, through January 31, 2027, were 17.323 cents per kWh for Eversource East, 15.934 for Eversource West, 17.185 for National Grid’s fixed option, and 18.921 for Unitil, according to the Massachusetts Department of Public Utilities rate information. Use the figure for your own territory.

Early termination fees and cancellation rules

Find the early termination fee before enrolling. Check whether the fee applies when you move, whether any exceptions exist, and how you must submit a cancellation.

Massachusetts residential contracts carry a three day right to cancel after signing. Keep the enrollment date and the cancellation instructions where you can find them.

Deposit requirements and enrollment conditions

Ask whether the supplier requires a deposit or credit check. Confirm which documents or account details are needed for enrollment. A sales pitch that skips these conditions is incomplete.

Also check whether the quoted rate requires autopay, electronic billing, or a minimum usage level. Those conditions can affect the rate you actually receive.

What the Electricity Facts Label can reveal

The Electricity Facts Label can show the supply rate, contract term, renewable content, fees, and other conditions. Read it beside your current bill instead of reading the headline alone.

This is where the full contract matters. A low starting number may not describe the rate after a credit ends or the term renews.

What happens when you switch suppliers

Enrollment is usually handled through the supplier, while your utility continues to deliver power. The change is administrative, so you should not need new wires or a new meter. Your service should continue during the change.

The timing and first bill depend on the utility’s billing schedule. Keep your old bill until the first bill showing the new supply rate arrives.

How enrollment is submitted

You generally provide the account information requested by the supplier and agree to the contract terms. Review the final rate and term before you submit the enrollment.

Do not rely only on a salesperson’s summary. Save the EFL, contract, confirmation email, and enrollment date.

When the new supply rate takes effect

A switch can take up to two billing cycles. The new rate may not appear on the next bill if the utility has already closed its enrollment window for that cycle.

Watch the supply section of the bill rather than assuming the change happened on the day you enrolled. Contact the supplier if the timing does not match the written confirmation.

What stays the same on your electric bill

Your utility generally continues to send the bill and collect the delivery charge. The meter, delivery system, and outage contact remain the same. The supply line is the part most likely to change.

This makes it easier to compare before and after. Put the old and new supply lines side by side and check the rate, usage, and any credit.

How to return to the utility’s basic service

You can ask the supplier about cancellation and contact the utility about returning to Basic Service. The effective date depends on the contract and the utility’s processing schedule.

Check for an early termination fee first. Keep written confirmation of the request and review later bills until the supply source changes.

Important risks and consumer protections

Competitive supply can create useful choice, but the contract can also create confusion. The biggest risks are teaser rates, usage conditions, and unclear sales claims. A careful reading protects you better than a low opening number.

Use public information and your own bill as the evidence. If a claim cannot be matched to the written offer, pause before enrolling.

Teaser rates and usage assumptions

A teaser rate may apply only at one usage level or for a limited period. A credit can disappear when your usage falls outside a stated range. Your normal usage matters more than the example shown in an advertisement.

The Real-Bill Ranking starts with your actual bill rather than a made-up household profile. ChooseMyPower’s plan comparison tool is built to show a live plan table drawn from partner plan data and accepts a ZIP code, so a shopper can begin with an address rather than a slogan.

Door-to-door, phone, and mail solicitations

A salesperson should identify the company and explain the contract clearly. Do not share an account number until you understand why it is needed. You can end the conversation and verify the offer independently.

Be cautious when someone suggests they represent your utility without showing clear identification. Your utility does not need your permission to restore power during an outage, and a supplier switch is a separate transaction.

Recognizing misleading supplier claims

Watch for claims that promise a guaranteed lower bill or hide the difference between supply and delivery. A supplier cannot control every part of your electric bill. Ask for the rate in cents per kWh and the complete written terms.

The Massachusetts Attorney General reported a net loss of $87.4 million for residential customers in the twelve months from July 2024 through June 2025, tied to individually chosen competitive supply, according to its 2026 report, and it keeps its standing guidance for households on its competitive electric supply page. That figure is a warning to examine the contract, not a reason to confuse individual supply with municipal aggregation.

Where to check Massachusetts energy-shopping information

Start with your utility bill, your town’s notices, and state consumer information. The state’s Energy Switch Massachusetts site can help you review energy-shopping information. Verify the current rules and offer details before enrolling.

A supplier’s website and a sales flyer are not substitutes for the contract. Compare the written terms with what you were told.

How to decide whether a supplier switch fits your situation

A switch may fit if you can shop at your address and the written offer makes sense against your current supply arrangement. It may not fit if the rate depends on conditions you cannot meet or the contract is hard to understand.

There is no need to decide from a headline. Work through the bill, EFL, rate, term, and cancellation rules in that order.

Compare the offer with your current supply rate

Find the supply rate on your latest bill. Then compare it with the new rate using the same unit, usually cents per kWh. Keep delivery charges out of this first comparison because they usually do not change with the supplier.

ChooseMyPower’s plan comparison tool can help you view plan information after you enter a ZIP code. Use the displayed offer as a starting point, then confirm every detail in the supplier’s EFL and contract.

Check the plan against your expected usage

Typical Massachusetts household use is about 570 kWh a month. For a simple worked comparison, use 600 kWh and then replace that estimate with your own recent usage.

Check whether credits, minimums, or usage bands apply at your actual level. A plan that looks attractive at one usage amount may work differently at another.

Review the full contract before enrolling

Read the rate section, term, renewal language, fees, deposit rules, and cancellation process. Make sure the written offer matches the sales pitch. If a key condition is missing, ask the supplier to explain it in writing.

You have a three day residential right to cancel after signing. That short period is useful, but reading before enrollment is safer than relying on cancellation later.

Keep records of the rate, term, and cancellation rules

Save the EFL, contract, confirmation page, and first bill. Write down the enrollment date and the date the rate should begin. These records make a billing question easier to resolve.

The ChooseMyPower plan comparison tool can help you start with plan details, while your signed contract remains the controlling document for the enrollment. Use both the comparison view and the paperwork in front of you.

A Practical Next Step

Massachusetts also runs its own free comparison site, Energy Switch Massachusetts, which lists offers from licensed suppliers and takes no referral fee.

More on Massachusetts: the Basic Service rate for your utility and the four situations you could be in, should you opt out of municipal aggregation, are competitive suppliers worth it in Massachusetts.

If your address is eligible for shopping, compare plans by entering your ZIP code, then check the offer against your bill and EFL before enrolling.

Conclusion

You can choose an electricity supplier in some parts of Massachusetts, but eligibility comes first. Identify your utility, town, and current supply arrangement, then compare the full contract instead of the opening rate. Delivery stays with your utility, and careful records help you spot when the new supply terms take effect.
