New publication by Muhammad Maladoh Bah in Energy Policy, Volume 182
Highlights
- Ex-post profitability of state subsidized nuclear plants is presented.
- Nuclear plants were able to rely on market revenues without the need for state support.
- No economic justification for the introduction of federal nuclear support schemes.
- State support schemes should be flexible and market linked.
«Abstract: Since 2017, several U.S. states have put in place out-of-market financial support schemes for nuclear power plants operating in deregulated electricity markets. In late 2021, the federal government announced the introduction of two new support schemes to secure the continued operation of nuclear power plants. This policy perspective evaluates the profitability of state subsidized nuclear power plants in the NYISO and PJM markets over a five-year period between 2017 and 2021. Results indicate that apart from 2019, nuclear power plants were financially robust, relying solely on market revenues without the need for state support schemes. More importantly, the recent upswing in competitive electricity market prices suggests that additional federal support schemes are not economically justified in current market conditions. I provide several suggestions to reconfigure the support schemes to reflect dynamic market conditions and ensure only vulnerable plants are granted out-of-market support.»
