The Turbine Bottleneck

When historians of the American power system look back on this decade, they may conclude that the defining constraint was not a shortage of fuel, capital, or political will, but a shortage of machines. The clearest evidence arrived this week in the form of a quarterly earnings report. GE Vernova, the largest supplier of heavy-duty gas turbines in the United States, told investors that its reservations for new gas equipment had climbed to 116 gigawatts, up from 100 gigawatts only three months earlier, and that its total order backlog across all businesses had swelled to $176 billion. The company is now booking factory slots for turbines that will not be delivered until 2031. In a sector accustomed to measuring project timelines in months, a six-year wait for the single most important piece of equipment has become the new baseline, and it is quietly reshaping every assumption utilities, developers, and regulators bring to the table.
