Calpine, NRG post report that seeks changes in ERCOT pricing, settlement rules

5.10.2017

Calpine and NRG Energy filed Wednesday a commissioned report with the Texas Public Utility Commission that recommends changes to the Electric Reliability Council of Texas' pricing and settlement rules.

The commissioned report, titled "Priorities for the Evolution of an Energy-Only Electricity Market Design in ERCOT," was prepared by William Hogan of Harvard and Susan Pope of FTI Consulting.

Calpine and NRG, which are both big power generators in Texas, said they requested the report in the hopes of drawing attention to the difficulties the two are facing with subsidized renewables.

Texas has seen its wind generation reach roughly 21,000 MW of installed capacity, roughly one-fourth of the state's total generating capacity of about 84,000 MW.
