Senators introduce GRID Act targeting data center electricity costs

Senators Hawley (R-MO) and Blumenthal (D-CT) introduced the Guaranteeing Rate Insulation from Data Centers Act (GRID Act), proposing strict obligations and penalties for large data centers to prevent alleged increases in residential electricity rates.

• Main action: The GRID Act would require data centers with demand of 20 megawatts or more to either fully supply their own electricity (on-site generation/microgrids) or pay “rate effect credits” equal to any measured increase in local residential rates as determined by an annual DOE study; facilities that fail to comply face civil penalties up to $1 million per day.
• Background and context: The article is an opinion/analysis piece arguing the bill misattributes market-design failures to hyperscalers; it contrasts the GRID Act with Texas SB 6 (2025), which conditions access for loads above 75 megawatts on automated curtailment, offers faster interconnection priority, and provides capacity-style payments; the piece cites an example where utilities might otherwise wait to build $500M+ in transmission upgrades.
