Platts to launch new North American Renewable Capture Rates

Platts, part of S&P Global Commodity Insights, has decided to launch new daily renewable capture rates, effective June 4, to provide further transparency about the value of renewable energy across the US.

Capture rates are important because they measure the economic performance of renewable energy generation by indicating the revenue realized compared with the potential revenue at the baseload power price. High capture rates suggest effective market integration and profitability, while low rates may highlight challenges, influencing investment decisions and energy policy development.

For example, a 50% capture rate in the context of renewable energy indicates that half of the potential renewable energy resources available in a specific area or system are being effectively harnessed and converted into usable power. This shows potential challenges in market integration, pricing competitiveness, or demand for renewable energy, signaling that improvements may be needed to enhance profitability and market performance.

Platts will publish daily renewable capture rates in seven North American independent system operators: California Independent System Operator, Electric Reliability Council of Texas, ISO New England, Midcontinent Independent System Operator, New York Independent System Operator, PJM Interconnection and Southwest Power Pool.

Wind capture rates will be published for CAISO, ERCOT, ISONE, MISO, NYISO, PJM and SPP, and solar capture rates will be published for CAISO, ERCOT, ISONE, MISO and PJM.

Platts will utilize published capture prices from across the US and the wholesale electricity prices from ISOs for the corresponding hubs and zones. Renewable Capture Price Rates will be measured in %.

The new capture rates were proposed in a subscriber note published March 28.

The new prices will be published in Megawatt Daily, Energy Trader, Platts Connect and Alert Pages PEA1108 and AGP1518.
