Washington Electric Cooperative

Washington Electric Cooperative serves customers in Calais, East Montpelier, Marshfield, Middlesex, Plainfield in Vermont with a residential electricity rate of $0.30 per kWh. This is 79% above the national average of $0.168/kWh, meaning solar savings are especially significant for customers looking to reduce their energy costs.

At current rates, a typical Washington Electric Cooperative household using 900 kWh per month spends approximately $3,241 per year on electricity. An 8 kW solar system can offset most or all of that usage, saving an estimated $2,881 annually and $105,038 over the 25-year life of the system. With Vermont incentives of $800, the net system cost drops to $24,192, with a payback period of just 8.4 years.

Washington Electric Cooperative offers net metering for solar customers. Third-party ownership through solar leases and power purchase agreements (PPAs) is available, which can qualify for the 30% commercial Investment Tax Credit under Section 48.

The federal residential solar tax credit (Section 25D) expired at the end of 2025. State and utility-level incentives are now the primary financial benefits for homeowners going solar.
