Senate targets grid costs

Rising power demand from AI data centers, hyperscalers and other large new customers is intensifying pressure on the U.S. electric grid and on who pays for expansion. New legislation from Senator Martin Heinrich seeks to shift those connection and upgrade costs to the biggest new users while adding incentives for transmission investment.

Highlights

  • The GRID Savings Act would require large new electricity users to follow the same grid upgrade cost-allocation rules as new power plants, shifting costs away from households and small businesses.
  • Under the bill, the Federal Energy Regulatory Commission must establish rules on required facilities, cost assignments, and customer payment obligations for major new grid connections.
  • Large electricity users could voluntarily fund backbone transmission upgrades in exchange for transmission service, encouraging private investment in grid capacity expansion.

Bill would align large loads with generator rules

As reported by Senate Energy Committee, citing the Senate Committee on Energy and Natural Resources Democratic News, Heinrich introduces the GRID Savings Act to require very large new electricity users to follow cost-allocation principles that have long applied to new power plants.

Under the proposal, companies seeking major new grid connections would face a review process, pay for upgrades needed to connect safely and reliably, and provide financial commitments showing their projects are moving forward. The bill directs the Federal Energy Regulatory Commission to establish clear rules on what facilities are required, how costs are assigned and what each customer must cover.

Heinrich says the measure is designed to prevent households and smaller businesses from subsidizing infrastructure built mainly for high-demand customers. The legislation also aims to improve transparency and protect grid reliability as electricity demand continues to grow across the country.

Transmission incentives and broader grid strategy

The measure also allows large electricity users to voluntarily fund certain transmission facilities and receive transmission service in return for supporting backbone transmission upgrades. That provision is intended to encourage private capital to help expand capacity on the broader network, not just local connections.

Heinrich has for years backed transmission expansion, interregional planning reform and efforts to reduce interconnection delays in the U.S. power system. The announcement also points to his support for the SunZia project in New Mexico, now fully operational and delivering up to 3,650 megawatts of energy across the Southwest, as part of his broader push to modernize the grid and support economic growth.

Our earlier coverage of July’s ISM manufacturing report noted that U.S. factory activity strengthened, with production and new orders improving and the sector’s employment gauge returning to expansion. We also pointed out that persistent supply constraints, tariffs and geopolitical disruptions were keeping input costs elevated, complicating the inflation outlook ahead of the Fed’s September policy meeting.
