Springfield business energy: Eversource

Eversource delivers, through the company the city's plan calls WMECo

The delivery utility is the first fact to pin down in Massachusetts, because the Eversource and National Grid companies file separate tariffs and the rate class on the bill follows whichever company serves the address. Boston's delivery comes from the company the utility still files as NSTAR Electric; Worcester's comes from National Grid. Springfield's comes from Eversource's Western Massachusetts company, and the city's own aggregation plan names it in language a reader can check: an eligible consumer may decline the programme and remain with the Local Distributor, Eversource Energy, which the plan glosses as formerly WMECo. Eversource's own service list pairs that Western Massachusetts electric company with Eversource Gas of Massachusetts, the gas affiliate for the same region, so a Springfield site can take two fuels from two Eversource entities under two tariffs. None of that widens the eligibility boundary: competitive supply depends on the service address, the meter and the utility territory, and municipal utilities, cooperatives and some jurisdictions have no choice at all. In Massachusetts the municipal light plants are the standing example of an address where nothing can be shopped.

• Springfield electric delivery comes from Eversource's Western Massachusetts company, the one the city's plan calls WMECo.
• Boston's Eversource company files as NSTAR Electric and Worcester's distributor is National Grid, so the class ladder differs from city to city.
• Eversource's own service list pairs Western Massachusetts electric service with Eversource Gas of Massachusetts.
• Delivery, metering, outage response and billing stay with the utility in every case; only the supply line can be bought elsewhere.
• Confirm the service address, the meter and the territory before comparing anything: competitive supply is not available at every address.

Order 7109, the plan, and the supply start

Springfield's programme has a dated paper trail, and the dates are the part a business can use. The City Council approved Order 7109 in December 2022, and the city then developed and published an aggregation plan under the Massachusetts statute that lets a municipality aggregate the electric load inside its borders, G.L. c. 164, section 134, working with the consultant Colonial Power Group and the state Department of Energy Resources. The Council approved the plan in June 2024, and the power supply agreement took effect in December 2025. The programme, which had been publicised as the Green Municipal Aggregation Programme, now trades as the Community Choice Power Supply Program, and the city describes it as aggregating the buying power of more than 155,000 consumers. Its supplier, First Point Power, serves the accounts that were on Eversource Basic Service in Springfield, and the offer is split in two: a standard product that eligible consumers are enrolled in unless they opt out, and an optional premium product carrying renewable content above the state's minimum requirement. The premium product is entered only when a consumer asks for it.

• Order 7109 cleared the City Council in December 2022; the plan was approved in June 2024 and supply took effect in December 2025.
• The plan was built under G.L. c. 164, section 134, with Colonial Power Group as consultant and the Department of Energy Resources involved.
• The programme aggregates the buying power of more than 155,000 consumers.
• First Point Power supplies the accounts that had been on Eversource Basic Service.
• The standard product is opt-out; the premium product, with renewable content above the state minimum, is entered only by affirmative selection.

The notice arithmetic: thirty-seven days, thirty-six days, one meter read

An opt-out aggregation runs on a deadline structure, and Springfield's plan sets it out in a way an account can plan around. Eligible consumers receive a written opt-out notice, and the opt-out period runs a full thirty days plus six days for mailing, so it ends thirty-six days after the notice is mailed. The supplier's enrolment transaction cannot be submitted until at least thirty-seven days after mailing, and it must arrive two full business days before the meter read. Enrolment then takes effect at the account's next meter read, which is why the switch date is a meter-read date rather than the date a reply card was posted. A notice returned as undeliverable does not produce an automatic enrolment at all. The plan's own estimate is that the city, the supplier and the utility need about two months to complete notification and enrolment for the accounts being moved, and it states that the mechanics follow the utility's filed terms and conditions for competitive suppliers.

• The opt-out period ends thirty-six days after the notice is mailed: thirty days plus three days each way for mail.
• An enrolment transaction goes in no fewer than thirty-seven days after mailing and two full business days before the meter read.
• The change takes effect at the account's next meter read.
• A notice returned as undeliverable does not create an automatic enrolment.
• The plan estimates about two months for the whole notification and enrolment process.

What moves, and what stays exactly where it is

An aggregation changes the supply line and nothing else, and the eligible set is defined narrowly enough to matter. The plan adopts the Department's definition from its municipal aggregation guidance at D.P.U. 16-10: eligible consumers are accounts on Basic Service, accounts on Basic Service that asked the utility not to share their contact details with suppliers for marketing, and accounts taking Basic Service alongside a green power product that allows concurrent enrolment. Excluded are accounts that asked the utility not to enrol them, accounts on a green power product that prohibits switching, and accounts already receiving competitive supply. That last exclusion is the commercially important one: a Springfield business under its own supply agreement sits outside the eligible set and has to opt in, which makes the existing contract the first document to read. Leaving the programme is free at any time. The route back to Basic Service differs by account type, because a commercial or industrial account that notifies Eversource directly is terminated at its next scheduled meter read, while a household account on the same route transfers within two business days. Both routes run through the utility's competitive-supplier terms and conditions rather than the city's plan alone.

• Eligible consumers are Basic Service accounts, including those whose contact details are withheld from supplier marketing.
• Accounts already on competitive supply are outside the eligible set and must opt in.
• Opting out is free, whether before supply starts or at any time afterwards.
• A commercial or industrial account returning to Basic Service is terminated at its next scheduled meter read.
• Enrolment and return mechanics follow the utility's filed competitive-supplier terms and conditions.

Why the city buys in bulk, and what it declines to promise

Springfield's programme exists for reasons the city states, and they are procurement reasons rather than a discount. The plan ties the programme to the city's climate agenda and to price stability, and it allows the standard product to carry renewable content beyond the state's minimum requirement; the premium option on offer is built from Massachusetts Class I renewable energy certificates. Supply is bought out of the wholesale market that ISO New England runs for the six New England states. The city is also explicit about the limit of the exercise: basic service prices move twice a year or more depending on the rate class, so a programme rate will not always sit below the default, and future savings cannot be guaranteed. That is the honest description of what an aggregation is, a bulk procurement method with renewable-content and price-stability arguments attached and a contract term a participant has to plan for. A Springfield business choosing how to buy supply is therefore weighing three things rather than two: the programme's product, the utility's Basic Service, and whatever a competitive supplier offers the account directly.

• The plan links the programme to the city's climate goals and to price stability rather than to a guaranteed discount.
• The premium option is built from Massachusetts Class I renewable energy certificates.
• Basic service prices change twice a year or more, depending on the rate class.
• The city states plainly that future savings cannot be guaranteed.
• The programme's product, Basic Service and a direct supplier offer are three separate options, not two.

Who pays for the programme, and who approves its notices

A municipal aggregation's economics are worth reading separately from its supply price, because the programme itself is not free to run. Springfield's plan says the programme's start-up costs are carried by the consultant, that initial funding comes from private capital the consultant supplies, and that ongoing costs are met from a consultant fee set out in the power supply agreement and paid by the competitive supplier rather than charged to participants as a separate line on the bill. The plan also draws the approval boundary around the programme's communications: any opt-out opportunity beyond the initial one, and the public education and outreach material that supports it, must be approved by the Department of Public Utilities. For a business reading the documents, that is a useful distinction. The supply price is a contract term between the city and its supplier, the programme's running costs are settled between the supplier and the consultant, and the customer-facing notices that determine when an account can leave are filed with a state regulator. Each of the three sits in a different document, and a question about the account usually belongs to the last one.

• The plan states that start-up costs are carried by the consultant and funded from private capital.
• Ongoing programme costs come from a consultant fee paid by the competitive supplier, not billed to participants separately.
• Additional opt-out opportunities and the outreach material supporting them require Department of Public Utilities approval.
• Supply price, programme costs and customer notices sit in three different documents.

What a Springfield account should have in hand

The paperwork that decides a Springfield supply question is mostly already on the bill and in the contract the account holds. The rate schedule and voltage class on the bill establish what the utility charges for delivery and what a supplier's offer is priced against. The account and meter numbers together with the meter-read date decide when an enrolment or a return can take effect, because both are timed to the read. Whether the account is currently on Basic Service or under a competitive contract decides whether the programme will enrol it automatically or whether it has to opt in, and an account that opts in should have read its existing agreement's end date and notice terms first, because those decide whether leaving costs anything. A business that wants renewable content above the state minimum should ask which product it is being offered, since only the optional one carries it and only by affirmative selection. Confirming that the service address is inside the city and inside the utility's territory comes before any of the rest.

• Rate class, voltage and delivery charges, read off the bill.
• Account and meter numbers, plus the next scheduled meter-read date.
• The supply arrangement in force and, where contracted, its end date and notice terms.
• Which product is offered, and whether the renewable content comes with the standard or the optional product.
• Confirmation that the address is inside the city and inside the utility's territory.
