Data centers that don’t exist yet are already haunting the grid

illuminem summarises for you the essential news of the day. Read the full piece on The Wall Street Journal or enjoy below:

🗞️ Driving the news: U.S. power utilities are being overwhelmed by requests for electricity from data centers — many of which may never be built — raising fears that "phantom demand" is distorting grid planning and investment decisions
• Developers have submitted interconnection requests totaling nearly 400 gigawatts (GW) — more than half of the U.S. grid’s peak summer demand — fueling concern among utilities and regulators

🔭 The context: The explosion in artificial intelligence and cloud computing is behind the surge in proposed data center projects, many seeking access to cheap, reliable electricity in regions like Texas and the Midwest
• However, utilities say many developers are flooding the system with multiple speculative applications, leading to unrealistic demand forecasts and costly overbuild risks
• American Electric Power has seen requests for up to 190 GW, compared to a current system size of 37 GW — five times more than it can serve
• CenterPoint Energy and Oncor have also reported skyrocketing requests, with individual cities like Houston seeing demand jump from 1 GW to 25 GW in just one year

🌍 Why it matters for the planet: Grid miscalculations could lead to overinvestment in fossil-fuel backup generation or underinvestment in renewable infrastructure, weakening progress toward clean energy targets
• As utilities struggle to separate real from speculative demand, climate-aligned grid expansion becomes more difficult — potentially delaying decarbonization efforts tied to AI and tech sector growth

⏭️ What's next: Utilities and regulators are calling for reform to the project request process, including higher financial commitments from developers to ensure only serious projects move forward
• Without intervention, grid operators warn of distorted investment, higher consumer costs, and slower clean energy transition timelines

💬 One quote: "A lot of it is real, but how much?" – Tom Falcone, President of the Large Public Power Council

📈 One stat: 400 gigawatts – The total capacity of data center energy requests submitted to U.S. utilities, equivalent to powering over 300 million homes
