Regulating electricity spot markets during extreme events: The 2021 Texas case

Armen Danielian

Utilities Policy, 2025, vol. 93, issue C

Abstract: This paper discusses the economic and legal challenges of price regulation in spot electricity markets during extreme events, taking the 2021 Texas winter storm as an example. The dual role of spot electricity prices (resource allocation and overall system reliability) in ERCOT's energy-only market resulted in allocating system reliability costs to load-shed consumers and spot electricity buyers, implying that complementary tools for covering system reliability costs should be sought. Further nuances are highlighted through a comparative qualitative analysis of value-of-lost-load pricing and anti-gouging legislation in the event context.
