Helion announces world’s first fusion energy purchase agreement with Microsoft
Fusion energy just took a big step from lab to grid: Helion Energy has signed the world’s first commercial fusion power purchase agreement, promising Microsoft at least 50 megawatts of electricity from a plant targeted to come online in 2028. That timeline is roughly a decade ahead of most expert projections for commercial fusion. Helion has already built six prototypes and reached the 100-million-degree plasma temperatures considered necessary for self-sustaining reactions, with Constellation handling the grid-side logistics. The engineering road ahead is steep, and nothing is guaranteed. But moving fusion from research aspiration onto a real buyer’s procurement list is a meaningful shift, hinting at a future where zero-carbon baseload power becomes a practical piece of the climate puzzle.
