Data centres chase power
Data-centre operators are increasingly buying or building their own power systems because grid queues and interconnection delays are slowing deployments. A CBS-cited report says data centres could drive as much as $1.4 trillion of grid investment, and operators are turning to behind‑the‑meter generation, microgrids and on‑site fuel cells to move faster than utilities can upgrade lines and substations. Vendors and investors are starting to treat batteries, fuel cells and grid‑services as part of the AI infrastructure stack rather than peripheral suppliers.

Data-center developers are increasingly lining up power before they line up land, because utility hookups are taking too long for new artificial-intelligence campuses. (cbsnews.com) U.S. investor-owned utilities now plan to spend at least $1.4 trillion on capital projects through 2030, up more than 21% from the five-year outlook they gave a year earlier, according to a PowerLines review of 51 utility earnings calls released on April 14. PowerLines said data centers were a top driver of that spending. (powerlines.org) A data center cannot open without a firm power connection, and the queue to connect new generation to the grid has become a bottleneck of its own. Lawrence Berkeley National Laboratory said projects seeking interconnection totaled about 2.6 terawatts at the end of 2023, roughly twice installed U.S. generating capacity. (emp.lbl.gov) That is why operators are building “behind-the-meter” systems, which means power equipment placed on the customer side of the utility meter so a site can run without waiting for every transmission and substation upgrade. Data Center Knowledge reported on April 15 that developers are turning to microgrids, on-site generation and flexible power systems to shorten deployment timelines. (datacenterknowledge.com) A microgrid is a small local network that can draw from gas turbines, fuel cells, batteries, solar panels or wind turbines and keep operating even if the wider grid is strained. Ramboll said data-center owners are using microgrids to control capacity and improve reliability as facility loads climb. (ramboll.com) The load is climbing because newer artificial-intelligence servers pack more chips into each rack and pull far more electricity than older cloud hardware. CoreSite said average density is around 15 kilowatts per rack today, while artificial-intelligence deployments can require 60 to 120 kilowatts per rack. (coresite.com) Fuel cells are getting attention because they make electricity on site from fuel rather than by burning it in a conventional turbine, and vendors say they can be installed faster than major grid upgrades. Bloom Energy said one data center’s load can swing by 50 to 100 megawatts and argued that fuel cells paired with batteries or supercapacitors can respond to those spikes. (bloomenergy.com) The politics are shifting with the engineering. On March 4, seven technology companies accepted a White House “Ratepayer Protection Pledge” saying they would build, bring or buy the energy needed for their data centers and pay the full cost of related infrastructure. (whitehouse.gov) That pledge did not settle the fight over who ultimately pays. CBS reported that analysts expect utilities to recover much of their grid spending through customer bills, while consumer advocates and some lawmakers are pushing for data-center operators to cover more of the cost directly. (cbsnews.com) The result is that power gear once treated as backup equipment is moving into the center of data-center planning. In the current buildout, batteries, fuel cells and microgrids are being bought as core infrastructure, because a server hall without electricity is just an empty shell. (datacenterknowledge.com)
