US bit barn boom sees energy needs grow 10x as fast as grid capacity
Howden's analysis of data from the US Energy Information Administration (EIA) and S&P Global found that since the year 2000, power being fed to data campuses has risen 19 percent a year on average, while the electricity grid expanded capacity by just 2 percent per annum over the same period.
Key points
- The graph makes it appear that the two lines are about to cross, but the chart uses different scales: 1,400 gigawatts on the left axis for grid capacity, versus just 80 on the right for datacenters.
- Datacenter power consumption in the US is growing roughly ten times faster than grid capacity, meaning facilities may soon need to find a large chunk of their own electricity from other sources.
- Insurance broker Howden calculates that datacenters would need to source up to 58 percent of their power off the grid by 2030 just to keep their share of grid capacity from growing.
Management consultancy Bain & Company issued a report two years ago warning that energy companies must switch gear and invest in building out grid capacity faster, as energy draw by server farms is expected to more than double by 2030.
Additional details
- Keeping datacenters at five percent of grid capacity requires 110 gigawatts of behind-the-meter capacity by 2030, Howden estimates – an expansion it considers unlikely.
- Surging demand for AI infrastructure is driving a wave of new server farms across America, but it is exposing long-term underinvestment in the grid networks required to deliver power where it's needed.
- Datacenters' share of US grid capacity was circa five percent in 2025, up from 0.1 percent in 2000 – a 50-fold increase.
- For the largest, most power-constrained projects, Howden warns that grid delays of two to six years could mean $800 million to $2.4 billion in forgone revenue.
- Instead, it expects a combination of greater reliance on the grid, slower development at power-constrained sites, and alternative supplies.
