Savings cannot be guaranteed

Please note that, while Sharon Power Choice offers the potential for savings when compared with Eversource’s and National Grid’s Basic Service prices, there is no guarantee of savings. This is because the utilities’ Basic Service prices change seasonally, and their future Basic Service prices are unknown.
