Event Description

The Southwest Power Pool (SPP) Marketing Monitoring Unit (MMU) has released a report, “Self-committing in SPP markets: Overview, impacts, and recommendations”.  Highlights from the report include:

  • The volume of self-committed megawatts has declined over time, but remains nearly half of the recent megawatt volume.
  • In almost all cases, self-committed generators had lower revenues because of negative congestion prices; whereas, market-committed generators typically had both positive and negative congestion prices.
  • Resources with long lead times and/or high start-up costs tend to be self-committed instead of market-committed.
  • In order to improve price formation and market efficiency, we recommend SPP and stakeholders work to reduce the incidence of self-commitments.
