The Federal Energy Regulatory Commission recently released its 2023 common metrics report tied to the performance of regional transmission organization and independent system operator markets.
The report is part of an initiative FERC undertook following a 2008 Government Accountability Office report “recommending that the Commission do more to track the performance and benefits of RTO/ISO [regional transmission organization/independent system operator] markets.”
It follows the July 2021 report, which established a set of common performance metrics for evaluating the performance of RTO/ISO markets and individual utilities in regions outside of RTO/ISOs in areas where these entities perform identical functions.
Key findings from the 2023 report include:
- RTOs/ISOs managed the dispatch of energy from a diverse set of generating fuel types from 2019 to 2022.
- RTOs/ISOs regions experienced varying levels of demand response implementation during 2019 to 2022.
- Load-weighted, fuel-adjusted locational marginal prices have varied across time and region.
- Among the four RTOs/ISOs with capacity markets, the net number of generating capacity units added to service varies significantly. The net number of additions within those RTOs/ISOs also changed over time.
- The net increase in megawatt capacity supply obligations also varies significantly across the four RTOs/ISOs with capacity markets, as well as within those RTOs/ISOs over time.
