As required by PUCT Substantive Rule 25.476, Renewable and Green Energy Verification, ERCOT has posted the 2016 Texas Renewable Content Calculator on ERCOT.com.
This spreadsheet contains the following information:
• Percentage of total system MWh generated by fuel type from each Texas-based generator
• MWh-weighted average annual emissions rate for each Texas-based generator
• Statewide average fuel mix
• Statewide system average emission rates for each type of emission
• Default fuel mix and default emission rates
Rule 25.476(h) requires each REP to update the Electricity Facts Label (EFL) for each product currently offered or offered during the preceding calendar year no later than July 1, 2017, so that its EFL displays the renewable energy percentages determined by using the 2016 Texas Renewable Content Calculator.
