Sustainability, Security, and Stability

We are strongly committed to providing competitive electricity prices and worry-free service to our customers through competitively-bid contracts. The Compact offers the security of a fixed-rate and stable power supply option for a specific time frame, typically six months, for residential and small commercial customers. The rate for large commercial customers changes every three months.

In 2017, we teamed up with our supplier, NextEra® Energy Services Massachusetts (NextEra Energy Services), to become a green aggregator, matching Compact customers' annual usage above the mandated state requirements with voluntary Renewable Energy Certificates (RECs) to provide a 100% renewable product. Read more about Green Aggregation.

While our standard supply products sources voluntary RECs from across the country, Customers can choose to opt-in to the CLC Local Green℠ program which matches either 50% or 100% of customer usage with Massachusetts Class I RECs from right here in New England.

Winter electric rates: expectations and mitigation

Cape Light Compact will set the electricity supply rates for its green aggregation power supply program for the winter of 2024 in late November 2023. These rates will cover the pricing term that begins with December 2023 meter read dates and ends on July 2024 meter read dates for residential and commercial customers. Once rates are set, the Compact will update its website, issue a press release, and post ads in local newspapers.

The Compact anticipates that power supply rates will increase this winter. Energy prices typically increase during the winter months in New England due to the region’s reliance on natural gas for both electricity generation and heating. Due to global increases in the demand for and price of natural gas, wholesale electricity prices in New England are expected to be higher. All retail and utility electricity suppliers are facing these high market prices.

Higher per kilowatt hour electricity rates reinforce the importance of participating in the Compact’s energy efficiency program to reduce kilowatt hour usage. You can learn more about steps you can take to minimize the impact of cost increases here.

Electric Power Suppliers are required by the Department of Public Utilities (DPU) to provide customers with a disclosure label. The label enables consumers to look at the energy sources, air emissions and information about the supplier in order to make a more informed choice of a power supplier. Consumers can compare energy labels to make the best choice based on their energy needs.
