What does Texas SB1789 do?
SB1789 fundamentally shifts regulatory oversight from passive reporting to active financial penalization, authorizing the Public Utility Commission (PUC) to reduce an electric utility’s Return on Equity (ROE) if infrastructure fails standards during weather events. The law significantly tightens the threshold for reliability enforcement actions (lowering the trigger from 300% to 200% above system average) and mandates strict structural integrity standards for all Investor-Owned Utilities, Municipally Owned Utilities (MOUs), and Electric Cooperatives.
