Rising Power Costs Push Data Centers to Track Energy Use at Granular Level

Wholesale electricity costs in the PJM Interconnection region rose 76 percent year over year in Q1 2026, intensifying pressure on data center operators to manage power more carefully. While multiple factors including gas prices, weather, and market design contributed to the increase, the spike underscores that power is no longer a routine background expense for data centers. Operators are being urged to move beyond facility-level utility bills and track energy consumption down to individual racks, servers, and GPU clusters. AI infrastructure compounds the challenge, as large GPU deployments can rapidly shift both power and cooling demand, making idle or underutilized accelerators especially costly. Identifying and reclaiming stranded accelerator capacity can effectively expand usable supply within existing facilities, potentially delaying the need for costly new infrastructure.
