Tennessee Energy Storage Policy and Market Overview

The energy storage market in Tennessee is nascent as regulators and utilities navigate ways to stimulate market competition. Tennessee’s current market and policy actions aim to reduce stress on utility-generating facilities as they incorporate renewables into their resource portfolios.

Tennessee offers various umbrella policies that incentivize clean energy and storage technologies broadly. The state has instituted two substantial clean energy tax credits for industries investing in alternative energy systems. The tax credits alleviate capital costs for certified new green energy production facilities and incentivize the adoption of innovative technology like battery storage systems.

Economic policies supporting energy storage are aiding initial deployment, but strings of community opposition have perforated development plans and conspired moratoriums. The Tennessee energy storage market has key policy components for growth but needs multilateral support from the state, utilities, and the public to encourage deployment and deliver affordable and reliable energy.
