BostonCAN is a member of the Municipal Aggregation Working Group that the City’s Environment Department has formed to help ensure that Boston’s Community Choice Energy (CCE) program reflects community priorities. (Note: Municipal aggregation is the legal term for CCE.) Working group members represent City departments and other stakeholder organizations. Monthly meetings began last December and have served to educate the group about different aspects of aggregation design. The February 28 meeting addressed alternative ways that a program can acquire green energy. Guest speakers Megan Shaw from the Cambridge Energy Alliance and Ann Berwick from the City of Newton each described the option that her municipality chose.
Newton’s program goes live this month with a 22-month contract. The program gets green energy by purchasing Class I RECs. A REC (Renewable Energy Certificate) is earned by a renewable energy producer (for example, a solar or wind farm) for each 1,000 kilowatt hours that it generates. RECs are sold on an open market. When people (including aggregations) buy RECs, they help to repay up-front costs for existing renewable projects and to encourage investment in new ones. Class I RECs are for energy produced in New England, New York, or parts of Canada, where they help to green our regional grid and to create local jobs. Newton’s default offering is 60% green (46% more than the current state requirement, or RPS, of 14%). Newton customers may also opt up to 100% green or down to the RPS level.
Cambridge’s second CCE contract started last November. The previous 18-month contract relied on RECs, prioritizing new-vintage solar RECs (SRECs) in order to incentivize local solar development. When the incentive fell short of its goal, Cambridge designed its current, 24-month contract with an “operational adder” (customer surcharge) that will be used to finance a new, City-owned solar project. Cambridge’s program has an opt-up to 100%; these customers pay for Class I RECs in addition to the adder. The program is currently collecting more money than it can use, and the City is considering different options, such as adding battery storage.
Because recent market prices for electricity have been low, Newton and Cambridge now offer their customers both greener energy and lower prices compared to Eversource. However, prices fluctuate, and Berwick said that Newton was careful never to promise its customers cost savings. Alternative ways to set prices for an aggregation will be the topic of the next working group meeting.
In later meetings, the working group will set priorities for Boston’s CCE program and discuss what design alternatives support those priorities best. To help members prepare, the City provided the following questions about green energy sourcing alternatives:
- Do we want to use RECS, direct investment in new renewables, or some combination of both?
- If RECs, do we want to buy a fixed percentage above RPS or a varying percentage based on energy prices? In either case, what’s our target amount of renewables?
- What types of RECs and/or renewable projects do we want to prioritize?
- How might we want to change the aggregation over time and in response to new circumstances?
- Do we want opt-up or opt-down options, and if so, what should these entail?
