Calculator

The goal of Dunstable Community Power is to provide savings when compared with the average of National Grid’s changing prices. This calculator makes it easy to compare Dunstable Community Power prices with National Grid’s most recent 12-month average prices. For current prices, visit the Prices page.

The calculator also quantifies the environmental impact of participating in the Dunstable 100% Green option.

Dunstable Community Power impacts only your electricity supply price (the cost of the actual electricity). National Grid’s delivery charges (the cost to bring electricity to your home or business) are not impacted by the program.

Compare to National Grid's Basic Service price

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