Platts proposes to use reported US NYISO electric behind-the-meter solar generation RPI data

Platts, part of S&P Global Commodity Insights, proposes to start using actual behind-the-meter solar data for the calculation of its Renewable Penetration Index for the US New York Independent System Operator (NYISO).

The change would be implemented starting on Sept. 15, 2023.

Platts is proposing this change to provide increased transparency of the solar penetration in the NYISO generation mix.

The change would allow Platts to publish solar RPI calculations for peak and off-peak, as well as data as reported by the ISO for daily hours 1-24.

The change would affect the daily calculations published in Megawatt Daily, Energy Trader, on Platts real-time fixed pages PEA 904, AGP 2904, on Platts Dimensions Pro, and in the Platts price database under the following codes:
