DAY AFFECTED: July 1, 2014

LONG DESCRIPTION: As required by PUCT Substantive Rule 25.476, Renewable and Green Energy Verification, ERCOT has posted the 2013 Texas Renewable Content Calculator on ERCOT.com. This spreadsheet contains the following information:

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, 2014, so that its EFL displays the renewable energy percentages determined by using the 2013 Texas Renewable Content Calculator.

Another Market Notice will be sent at a later date requesting that Retail Electric Providers submit EFLs to ERCOT pursuant to Rule 25.476(h).

ADDITIONAL INFORMATION: The 2013 Texas Renewable Content Calculator is available on the Labeling of Electricity page of the ERCOT website.
