PJM Capacity Costs Hit Record as Developer Freeze Clouds New Project Buildout
PJM cleared a record $16.4 billion across its last two capacity auctions; the queue is moving but the construction pipeline sat idle for years.
PJM's capacity market prices have spiked more than eightfold over the past several years, clearing a record $16.4 billion across its last two auctions and pushing utility rates higher across PJM states, according to a Canary Media analysis published Monday (2026-08-24). Projects are finally moving through the interconnection queue. But getting them built is a separate problem.4
Developers who applied for grid connection spent years immobilised. Canary Media reported Monday (2026-08-24) that those interviewed for a 2024 PJM interconnection study "effectively suspended all permitting and siting work and all equipment procurement work because they simply didn't know when it was going to come out of the queue." Equipment never ordered, permits never filed, and site agreements allowed to lapse; these are now the gap between regulatory clearance and megawatts actually reaching the grid.4
The demand side shows no such hesitation. Talen Energy cleared 10 GW in a PJM capacity auction, a position worth up to $2.2 billion, demonstrating the revenue available to generators already capable of meeting reliability standards. Constellation Energy, the largest U.S. nuclear operator, raised its 2026 EPS guidance to a range of $11.50 to $12.50 after Q2 adjusted EPS of $2.55 beat the consensus estimate by 9.5%, with revenue of $7.504 billion up 23% year over year. Nuclear output reached 44,160 GWh at a 93% capacity factor in the quarter.5
Yet Constellation shares have fallen 22.41% year to date. The stock was quoted at $272.88 in Yahoo Finance reporting published Monday (2026-08-24), with a forward P/E of 23 on a market cap near $96.7 billion. That gap between strong operational results and a falling share price suggests investors are pricing in slower-than-expected demand realisation, even as management raised guidance.5
The hyperscaler investment case remains aggressive. Microsoft, Meta, Amazon and Alphabet collectively plan more than $710 billion in 2026 capital expenditure, and the EIA's Annual Energy Outlook 2026 models data center electricity demand growing substantially, per reports from June 2026 (2026-06-12). Constellation already holds long-term power purchase agreements with Microsoft, Meta and CyrusOne, including a 380 MW contract signed at Freestone in February 2026 with exclusivity for an additional 380 MW.1
Bilateral contracts between data centers and generation developers could emerge as the dominant financing route for new capacity. Rutigliano and Hoos noted in Canary Media's July (2026-07-17) reporting that direct agreements between data centers and developers of generation, battery storage and demand-side resources could become an even larger channel than the capacity auction market itself. PJM's Reliability Backstop Procurement framework is designed to enable such contracting from March 2027 onward.2,1
Near-term supply is thin. PJM has roughly 5 GW of gas-fired plants approaching readiness and a comparable volume of batteries that could deploy relatively quickly.4 PJM Western Hub spot power stood at $73.72/MWh on Monday (2026-08-24), a price that tests whether developers consider the commercial case strong enough to fund a procurement restart after years of inaction.
The uranium fuel chain is positioning for a longer cycle. Cameco carries roughly 230 million pounds committed under long-term contracts and guides Westinghouse adjusted EBITDA at $370 million to $430 million (Cameco's share) for 2026, against revenue guidance of $3.13 billion to $3.37 billion.3 Uranium Energy Corp carried zero debt and $794 million in liquid assets in reporting published Monday (2026-08-24), operating what it describes as the largest new greenfield in-situ recovery uranium project launched in more than a decade.5 The URA uranium ETF fell 1.77% to $45.66 on Monday (2026-08-24), indicating fuel markets are not pricing an imminent build acceleration.
PJM's capacity auctions are generating record revenues for generators already online. The interconnection reform has begun clearing paper approvals across clean energy technologies. The harder test is whether the permitting, procurement and siting work abandoned during the queue paralysis can restart quickly enough — across solar, batteries and nuclear life extensions simultaneously — to prevent another auction cycle clearing at historically elevated prices.4
