- The US power grid runs at about 50% capacity on average nationally, built to handle worst-case peak demand (hottest summer day, coldest winter morning) but grossly underutilized most days
- Ian Magruder heads the newly formed Utilize Coalition, an industry-backed consortium including Google and Tesla, making the case that better utilizing existing grid capacity is faster and cheaper than building new power plants, transformers, substations, and wires
- US electricity costs have risen about 25% over the last six years, per host David Roberts, even as the cost of actually generating power has fallen thanks to renewables — the spending pressure comes from transmission and distribution infrastructure
- Grid utilization has been falling for 40 to 50 years, and Magruder said there is no state in America that has perfectly optimized its grid, calling spare capacity an opportunity 'now and everywhere'
- Brattle authored a report for the coalition defining system utilization as total energy delivered or produced over available system capacity over the same time period, noting utilization varies dramatically by geography
- Data center demand and electrification are driving utilities to plan major new builds, and the coalition argues that exploiting existing capacity is 'almost by definition' cheaper than building new
Why it matters: US electricity costs have risen roughly 25% over the last six years despite falling generation costs, per the host, because infrastructure spending flows to ratepayer bills. If exploiting existing capacity is cheaper than building new, ratepayers and data center customers could see lower costs and faster connection times — but the coalition is still in report-and-coalition-building phase, not deployment.
