The Role of Thermal Technologies in ERCOT

Key takeaways from the session include the following:

  • Growing load, renewable deployment, and an aging thermal fleet call for more flexible dispatchable capacity; over 8 GW of peakers are in the interconnection queue as Texas incentivizes firm and dispatchable technologies.
  • The wholesale market, Non-Spin, and ECRS are major revenue streams for peakers; the top-performing peakers achieved $200-250/kW gross margins in 2023 with optimized operating strategies.
  • Peaker (CT) margins can vary significantly in different weather years. Allocating Texas Energy Fund (TEF) awards to all 10 GW of thermal assets decreases the short-term gross margins of peakers, but plants awarded with TEF show improved financials.
