    AI Electricity Demand Diverges Between CEG Nuclear and VST Gas Fleets

    Question

    AI Electricity Demand Diverges Between CEG Nuclear and VST Gas Fleets

    Direct answer

    Tech hyperscalers continue to secure dedicated baseload electricity capacity to power expanding AI compute clusters. The divergence in asset profiles between Constellation Energy (22 GW nuclear fleet) and Vistra (62% natural gas capacity) offers two distinct operating exposures to power market pricing. While nuclear assets command clean-energy premia from corporate off-takers, gas-fired generation provides rapid dispatch flexibility during regional peak demand spikes across deregulated wholesale grids.
