Platts launches new solar capture price indexes for ERCOT electricity market effective Aug. 2

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

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

These new solar capture price indexes 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 launches 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

New ERCOT weighed average LMP solar capture indexes are measured in $/MWh.

These prices are 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, ISO's pricing data and plants' capacity, where applicable.
