Calgary‑based TransAlta disclosed a $1 billion purchase of two natural‑gas peaking plants near Denver owned by Blackstone. The assets, Mountain Peak Power and Canyon Peak Power, together supply 318 MW of capacity and are designed to meet peak‑demand spikes. They link to the Colorado grid, enabling rapid dispatch during demand spikes and supporting battery storage projects.

Mountain Peak Power began operations in September 2025, while Canyon Peak Power is slated for commercial in‑service in Q3 2026. The transaction is expected to close in early Q4 2026, giving TransAlta time to integrate the plants before they reach full output. Recent Colorado rules raise capacity credits, boosting revenue potential significantly. The deal strengthens the Canadian utility’s position in the fast‑growing western U.S. power market.

For investors, the acquisition represents a sizable capital outlay but promises stable cash flows from peaking contracts that command premium rates during electricity shortages. With the United States tightening reserve margins, assets that can ramp quickly command higher valuations. TransAlta’s move signals confidence in gas‑backed peaking as a bridge to a lower‑carbon grid.
