Tennessee Valley Authority Rate Forecast

Client:

This report investigates various risk factors that could have an adverse effect on TVA’s costs and, thus, rates in the next 10 years. The purpose of this report is not to forecast future rates, as the probabilities of many uncertainties are unknown, but rather to examine the extent to which some factors could increase costs and rates above expectations. Synapse has reviewed extensive historical materials as well as forward‐looking public materials and statements about expectations and plans in order to quantify the potential impact from several cost categories. Synapse analyzed the five risk factors and roughly quantified the potential rate increases over the next 10 years. We also developed an overall estimate of the potential combined impacts for 2026 and 2031 for MLGW that represent a reasonable range of possible futures, taking into account the potential impacts for the five risk factors over the next 10 years. Our analysis concludes that there are potential rate increase risks for MLGW customers ranging from 9 percent to 34 percent per year by 2031, for a total increase of approximately $90 million to about $340 million by 2031.
