By Mark Jaffe, EUCI energy writer The Midcontinent Independent System Operator (MISO) expects its peak load will grow about 35% in the next 10 years to 163 gigawatts (GW), spurred primarily by data center development, the grid operator said in a draft long-term forecast. The forecast for data center load is now double the level…

By Mark Jaffe, EUCI energy writer Data center capital investment jumped nearly 30% year-over-year in 2025 to $770 billion, more than was invested for the year in the oil and gas sector, according to an analysis by industry consultant Rystad Energy. Investment in data centers surpassed solar photovoltaic (PV) spending – which has been the…

By Mark Jaffe, EUCI energy writer Global electricity demand is set to grow at its fastest pace in years for the rest of the decade spurred by rising industrial production, use of air conditioning, and the build-out of data centers, according to the International Energy Agency (IEA). Electricity demand rose 4.3% worldwide in 2024 and…

By Mark Jaffe, EUCI energy writer Electric utilities across the country are adopting “large load tariffs” aimed at data centers in a move to protect against the hefty costs that come with the facilities and speculative projects. At least 36 utilities – from Dominion Energy in Virginia to Wisconsin Electric Power to Arizona Public Service…

By Mark Jaffe, EUCI energy writer Winter electricity demand is outpacing new generation, but resources should still be adequate, although some regions with data center demands may be vulnerable in extreme weather, according to the North American Electric Reliability Corp. (NERC). Peak demand is projected to be 20 gigawatts (GW) higher this winter than last,…

By Mark Jaffe, EUCI energy writer The independent market monitor for the PJM Interconnection is calling on federal regulators to reject an agreement to provide power to a planned Pennsylvania Amazon data center until there is evidence it won’t impact retail energy costs. The PJM is the largest grid operator in the U.S. covering Midwestern…

By Mark Jaffe, EUCI energy writer Five state utility commissions opposed to paying for what they see as renewable energy projects for other states are seeking to change the financing for $22 billion in transmission projects planned by the Midcontinent Independent System Operator (MISO). In a complaint filed with the Federal Energy Regulatory Commission (FERC),…

By Mark Jaffe, EUCI energy writer Prices for guaranteed power in the PJM Interconnection – through a capacity auction – rose 22% from last year’s price to $329.17 a megawatt-day, the nation’s largest grid operator announced July 22. The jump would have been even sharper at $389 a megawatt-day, if the PJM had not agreed…

By Mark Jaffe, EUCI energy writer U.S utilities have been caught “flat-footed” in the face of the soaring demand for electricity from data centers and manufacturing plants, according to a Wood Mackenzie study. Wood Mackenzie is tracking 134 gigawatts (GW) of proposed data centers across the U.S., a 68% increase from the 50 GW in…

By Mark Jaffe, EUCI energy writer Wholesale electricity prices in the U.S. are projected to rise by an average 12% this summer, and while the margin between demand and generation capacity will be thinner, there should be adequate capacity, according to a Federal Energy Regulatory Commission (FERC) assessment. Electricity demand this summer is expected to…

By Mark Jaffe, EUCI energy writer The Southwest Power Pool (SPP) – serving all or part of 14 states from Texas to North Dakota – will need as much as $263 billion in new generation and transmission through 2050 to support a peak demand projected to rise 40% to 80%. Those investments can be made…

By Mark Jaffe, EUCI energy writer U.S. utility sector investment in electric, gas, and water projects are projected to rise to more than $780 billion between 2025 and 2028, according to a research report by consultant and market analyst S&P Global. Total U.S utility energy investments are projected to set a record at $202 billion…
