Platts proposes new solar capture price indexes for ERCOT electricity market effective July 19

Platts, part of S&P Global Commodity Insights, proposes to launch new daily weighted average LMP solar capture prices, effective July 19, in the Electric Reliability Council of Texas (ERCOT) footprint to provide further transparency about the value of solar energy in the 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 the already tracked daily ERCOT solar hub price indexes, Platts proposes to publish the following daily weighted average LMP solar capture price indexes:

ERCOT North Zn Weighted Average LMP Solar Capture Price Index

ERCOT South Zn Weighted Average LMP Solar Capture Price Index

ERCOT West Zn Weighted Average LMP Solar Capture Price Index

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

Proposed prices will be published in Megawatt Daily, Energy Trader, Platts Dimension 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.
