Billions chasing megawatts
AI demand has brought billions of dollars in financing to a small group of little-known data centre developers, NBC News reported, while pushing those companies into fights over electricity, pollution and land.
The reason is load. A single AI-focused data centre can draw 50 to 100 megawatts on a sustained basis, comparable to a small city. Brookings notes that Anthropic has estimated training one frontier model will need five gigawatts by 2027, and that the US AI sector could require 50 gigawatts of new electric capacity by 2028 — roughly twice the peak demand of New York City.
Forecasts point the same way. The IEA's base case has global data centre electricity consumption reaching 945 terawatt-hours by 2030 and 1,200 TWh by 2035, while Goldman Sachs Research projects a 160 to 165 per cent rise in power demand by 2030 compared with 2023.
Protests over land and water
Communities are pushing back. Demonstrators protested against AI data centre expansion in Imperial, California, in July. In Louisiana, regulators approved plans for three new gas power plants to serve a Meta AI campus.
Data centres also consume water for cooling and occupy large parcels of land, which puts them in competition with farms and housing. The chips at the centre of the boom — AI accelerators and the semiconductor supply chain behind them — set much of the pace, because each generation of hardware raises the power density a site has to handle.
Who pays for the grid
The policy question is who covers the cost of new transmission lines and generation. Utilities and regulators are debating special tariffs for very large customers, so that households do not absorb the bill for infrastructure built for a handful of corporate campuses.
