America’s Record Clean Energy Buildout — and the Parallel System Emerging Beside It
The U.S. plans to add 86 GW of utility-scale power in 2026—the largest annual expansion in decades—led by solar and battery storage. But a parallel wave of privately built, gas-fired generation for AI data centers is emerging beyond traditional grid reporting.
Shadow Grid: The Grid Is Splitting in Two
Data center developers are building a parallel “shadow grid” to bypass delays and costs. With 47 GW emerging—rivaling grid builds—this system is largely invisible to planners. FERC’s response may unintentionally push more operators fully off-grid, deepening coordination and reliability risks.
