Platts to launch new solar capture price indexes for ERCOT electricity market effective Aug 2

Platts, part of S&P Global Commodity Insights, has decided to launch new daily weighted average LMP solar capture prices, effective Aug. 2, 2023, in the Electric Reliability Council of Texas (ERCOT) footprint to provide further transparency about the value of solar energy in this US regional electricity market.

These prices will be based on ERCOT wholesale electricity locational marginal pricing (LMP), solar power plants capacity, and zonal solar generation data.

These new solar capture price indexes will provide the market with increased transparency on how renewable revenues are changing through time as the energy transition accelerates and solar generation make up a greater share of the fuel mix.

In addition to already tracked daily ERCOT solar hub price indexes, Platts has decided to publish the following daily weighted average LMP solar capture price indexes:

AERCA00 ERCOT North Zn Weighted Average LMP Solar Capture Price Index

AERCC00 ERCOT South Zn Weighted Average LMP Solar Capture Price Index

AERCB00 ERCOT West Zn Weighted Average LMP Solar Capture Price Index

ERCOT weighed average LMP solar capture indexes will be measured in $/MWh.

Prices will be published in Megawatt Daily, Energy Trader, Platts Dimensions Pro and Alert Pages PEA1108.

Platts Renewable Capture Price Indexes track weighted average prices that renewable energy generators receive for the electricity they produce throughout the day, based on hourly generation, ISOs pricing data and plants capacity, where applicable.
