Data Center Power Needs to Jump 88%, Sparking $11.6B in Energy IPOs
CEG•US data centers’ power requirements are projected to rise from 41GW in 2025 to 77GW by 2030, fueling a record $11.6B raised by ten power infrastructure and clean-tech IPOs so far in 2026. This influx of capital into emerging energy solutions could heighten competition for Calpine’s natural gas generation assets.
1. Surge in Data Center Power Demand
Hyperscale data centers in the US are set to require over 77GW of capacity by 2030, up from 41GW in 2025. This anticipated 88% increase has driven ten power infrastructure and clean-tech companies to raise a combined $11.6B in IPO proceeds through mid-2026, with geothermal firm Fervo Energy securing $1.89B and debuting with a 35% share bump.
2. Implications for Calpine
As fresh capital floods into next-generation energy providers, Calpine may face intensified competition for long-term power contracts with data center operators. The shift toward novel renewable and geothermal technologies threatens to pressure pricing and margins on its traditional natural gas generation portfolio.
