Mansfield Municipal Electric Department to Participate in Flow Rights Agreement, Power Deal with Hydro-Québec

Mansfield, Mass. – November 6, 2020 – The Mansfield Municipal Electric Department (MMED) is participating in a flow rights agreement and hydro power deal which will increase the amount of carbon-free generation in its power portfolio.

MMED is participating in a five-year power flow rights agreement its joint action agency, the Massachusetts Municipal Wholesale Electric Company (MMWEC), and the Connecticut Municipal Electric Energy Cooperative (CMEEC) have signed with Hydro-Québec (HQ), a Canadian utility. The power is flowing on existing transmission lines, to which MMWEC and CMEEC have contractual rights to transmit power from Canada. It began flowing on November 1, 2020.

Under the deal, in exchange for monthly payments from HQ, the MMWEC and CMEEC contractual transmission rights are transferred to HQ, and HQ will flow clean hydro- power from northern Quebec to a delivery terminal just outside of Boston. In addition to other benefits, the arrangement brings clean, carbon-free hydro-power for use in New England. As one of MMWEC’s members, MMED will benefit from this agreement.

The flow rights agreement is the result of a joint solicitation by MMWEC and CMEEC, which also included a solicitation for carbon-free power. On October 29, 2020, MMWEC signed a power agreement with HQ. Under the power deal, MMWEC will reserve a portion of its flow rights and purchase carbon-free power flowed over that portion of the line. The cost of the power will be reduced by the value of the forgone flow rights revenue.

The five-year power purchase transaction will allow MMED to flow clean power down the transmission line, without the premium cost of some carbon-free generation. It is a firm power transaction, guaranteeing that the light department receives the power. Under the power deal agreement, MMED will receive .75 megawatts (MW) of power per hour, or enough generation to power 1,095 homes per year.

MMED’s power portfolio was 54% carbon-free in 2019; this transaction increases their carbon-free generation by approximately 3.2%.

“Mansfield Electric always seeks affordable renewable power supply options to our portfolio,” said MMED General Manager Joe Sollecito. “This agreement through MMWEC is a great addition to our non-carbon emitting resources and will greatly benefit Mansfield customers for the next five years.”

MMED is one of 19 MMWEC member utilities purchasing a total of 15 megawatts through this contract, which represents 131,400 megawatt hours annually.
