This RFP includes a broad range of potential generation sources, including nuclear, green gas, solar, storage, and wind, among others, and supports TVA's decarbonization initiative as TVA continues to explore carbon-free technologies, bring on additional renewable energy, and work to meet customer demand of renewable energy. 2023 Budget On July 28, 2022, the TVA Board notationally approved TVA’s budget for 2023.

In connection with approval of the budget, the TVA Board also authorized TVA to issue power bonds and enter into other financing arrangements in an aggregate amount not to exceed $2.0 billion during 2023.
