In the aftermath of Winter Storm Uri, the Texas Legislature passed SB 3, which among other things required the PUC to adopt certain market-related rules. A key component of the law required the commission to adopt weatherization rules no later than Dec. 1. This new rule will require both power generation companies and transmission service providers to quickly assess a company’s ability to comply with the new rule or navigate the potentially treacherous waters of a good cause exception for noncompliance. But it also means GCs at Texas energy companies have some decisions to make.
