The cost of electricity in Nantucket, MA, is influenced by a complex interplay of factors including National Grid's supply rates, delivery charges, and your individual energy usage. As of late 2025 and projected for 2026, residents can anticipate continued upward pressure on electricity prices due to grid investments, wildfire mitigation efforts in states like California, and ongoing utility rate cases. However, the island's unique infrastructure – two undersea cables connecting it to the mainland – ensures a consistent, albeit potentially expensive, supply.
Supply Costs: The 'supply' portion of your bill represents the actual cost of the electricity you consume, typically measured in kilowatt-hours (kWh). The average rate in Nantucket currently sits around 28.10¢ per kWh, although this can vary depending on the provider and contract. Expect to pay roughly 477 kWh per month, resulting in a supply cost of around $133.27 (477 kWh * $0.2810/kWh). National Grid’s rates are subject to change, so it's vital to monitor your bills and compare plans.
Delivery Costs: In addition to supply, you’ll also pay a delivery charge. This covers the cost of transmitting the electricity to your home. Delivery rates can vary significantly based on location and infrastructure. Delivery charges average around $80-$100 per month.
