Compare to Eversource's Basic Service price

Eversource’s most recent 12-month average prices: While the program offers a long-term fixed price, Eversource’s Basic Service prices change every 6 months or less. As a result, comparing the program prices with the most recent 12-month average of Eversource’s prices can provide a more accurate comparison than comparing with only Eversource’s current price.

Savings cannot be guaranteed

Please note that, while Valley Green Energy offers the potential for savings when compared with Eversource’s Basic Service price, there is no guarantee of savings. This is because Eversource’s prices change every 6 months for residential and small business customers and every 3 months for large business customers, and future Eversource prices are unknown.
