Alberta Regulator Rejects 1.4-GW Gas Plant Backing Data Center Campus
Alberta's AUC rejection signals tougher scrutiny of gas-fired power tied to AI data centers despite surging demand.
Alberta's utility regulator has rejected a proposed 1.4-GW gas-fired power plant that was designed to supply electricity to a data center campus. The decision marks a rare hard stop in a North American buildout that has seen planned gas capacity tied to data centers nearly double in the first half of 2026 alone.5
The rejection matters because it tests the assumption that soaring AI-driven power demand will clear regulatory hurdles for new gas generation. Traders and developers have been banking on rapid approvals for large-scale thermal plants to meet hyperscale demand, but Alberta's AUC just signaled that demonstrated need alone will not be sufficient.5
The scrapped project was intended to serve a data center complex that would have been among the largest in the province. Alberta has become a magnet for data center investment due to cheap natural gas and a deregulated power market, yet the AUC's ruling indicates the province is not prepared to rubber-stamp every large thermal asset that comes forward.5
The gas buildout for data centers has accelerated sharply this year. Planned gas-fired capacity tied to data centers nearly doubled in the first six months of 2026, according to industry tracking, as major technology companies signed long-term power agreements to secure supply for new AI campuses.5
That momentum has not been limited to Alberta. In the United States, Chevron and Engine No. 1 won a 20-year contract to supply natural gas-based electricity to a Microsoft data center project in West Texas, with the partners aiming to enable up to 4 GW behind the so-called Project Kilby development.1
But the approvals process is tightening in places. Wisconsin regulators are considering proposals for two new gas plants, and the debate there has centered on whether the state's review process can adequately protect the public interest in the rush to secure power for data centers. A University of Wisconsin-Madison study estimated particulate pollution from those plants over their 30-year lifespans could produce more than $1 billion in air quality damages.2
Backers of the projects argue the scale of new demand leaves little room for delay. A Microsoft campus and a Vantage project leased to OpenAI and Oracle are among the hyperscale tenants driving the Wisconsin proposals, and We Energies plans to acquire the plants outright if they are approved.2
Critics counter that the review process is structurally tilted toward approval. Maria Chavez, a senior energy analyst at the Union of Concerned Scientists, noted that by the time a utility reaches the point of demonstrating public need, a gas plant is already set for construction, leaving little opportunity to evaluate cost impacts or alternatives.2
The scale of the demand is hard to overstate. Clean energy forecasters have already had to revise expectations sharply upward, with one estimate showing projected data center load nearly double what analysts expected back in December. That figure exceeds what many grid operators believe the existing power system can accommodate.3
The Federal Energy Regulatory Commission is still waving through gas asset acquisitions. On Thursday (2026-08-13), FERC approved PowerTransitions' purchase of the 1,242-MW Roseton gas and oil-fired plant in Newburgh, New York, plus TransAlta's roughly $1 billion deal for two gas plants totaling 319 MW.4
TransAlta expects those new assets to generate about $33 million a year in cash flow, money the company plans to redeploy toward growth prospects including data centers in Centralia, Washington, and Alberta. That Alberta ambition now faces a more cautious regulator than TransAlta may have assumed.4
The divergence between federal approvals in the US and provincial opposition in Canada could reshape where new capacity actually gets built. Developers chasing data center load will weigh Alberta's regulatory risk against Texas and other US jurisdictions where approvals have moved faster.4
The question now is whether the AUC's rejection is an isolated call or the start of a broader pattern. Wisconsin's review, still pending, will offer the next signal on how much scrutiny gas plants tied to data centers can withstand in North America.2
