Electricity Costs in Tennessee

Tennessee residents love their electricity, ranking 13th in the county for direct use, according to the U.S. Energy Information Administration. Despite being among the highest users of electricity in the nation, Tennesseans spend close to the U.S. average thanks to low residential electricity prices of less than $0.11 per kWh. Nevertheless, households are still spending a great deal of their earnings on electricity. High electric bills can be a helpful factor in drawing in potential solar buyers, as the power that solar panels in Tennessee produce will help lower costs and provide a great deal of savings over the system’s lifetime.

Tennessee Solar Policies & Incentives

A 5 kW solar system can cost about $20,000. Tennessee offers incentives that can help lower the price by up to $8,000. Although Tennessee lacks strong solar policy and implementation, there are still resources for potential solar buyers to save money. The Tennessee Valley Authority offers a $1,000 rebate upon install, instantly lowering the cost of the system. Apart from this rebate, the state also offers performance payments and property tax exemptions. Without a state income tax, there are no solar tax credits offered. But with other money-saving options, a solar system can still provide a return on investment.
