How the market works
Massachusetts electricity has two main parts
Understanding the difference between supply and delivery makes electricity-rate comparisons much easier.
Electricity supply
Supply is the electricity you consume. Depending on your location and eligibility, it can come from utility Basic Service, municipal aggregation or a competitive supplier.
Electricity delivery
The local regulated electric utility delivers electricity, maintains the distribution system, handles outages and applies delivery charges.
Your electricity bill
Your total bill can include supply, delivery, transmission, distribution and other applicable charges. A supply-rate comparison is therefore not a complete bill comparison.
Massachusetts electricity rates
Compare utility and supply options
Massachusetts electricity rates vary by utility territory, rate period, supplier, contract and customer eligibility. Use this section as a directory rather than assuming one statewide rate.

How electricity shopping works in Massachusetts
Massachusetts separates electricity supply from electricity delivery. This means you may be able to choose your electricity supplier while the same local utility continues to deliver power to your home or business.
Check My ZIP Code
Step 1
Identify your utility
Your address is located within a particular electric utility territory. That utility handles delivery.
Step 2
Review the supply rate
Compare the electricity supply price expressed in cents per kilowatt-hour.
Step 3
Check the contract
Review the rate period, renewal provisions, cancellation terms and any applicable fees.
Step 4
Review renewable content
If renewable electricity matters to you, compare the renewable content and disclosures of each supply option.
Step 5
Compare the complete bill
Supply is only one component of the electric bill. Delivery and other regulated charges remain important.
