RTO Reckoning: White Paper Examines How Industry and Policy Trends Undermine RTOs, Cautions Against One-Size-Fits-All Mandates

Tuesday, July 13, 2021 - 12:00pm

This white paper examines whether the RTO model is well suited to handle demands that undermine the RTO paradigm itself.

Key Points: 
  • This white paper examines whether the RTO model is well suited to handle demands that undermine the RTO paradigm itself.
  • According to the white paper, RTOs are struggling under the weight of electricity industry changes that have occurred since the RTOs were designed more than two decades ago.
  • Especially troublesome are issues related to price formation which, under the RTO model, are misaligned with many of the public policies that seek to advance grid decarbonization.
  • These trends are chipping away at the foundation of the RTO model itself and call into question the commodification of electricity which is the principle underpinning how RTO markets buy, sell and deliver electricity.

State’s Grid Operator Asks Electric Customers Across California to Conserve Power Today from 4-9 p.m.
