Electricity

Data centers are a major new load. Your bill is still a local rate-design question.

AI-contributing11.8%LBNL reference-case share of U.S. electricity in 2030

What the evidence supports

LBNL’s 2026 update puts the 2030 data-center share at 11.8% in its reference case, with a 9.5%–15.3% scenario range. EIA says data-center growth is a major driver of rising U.S. load.

Mechanism: Large, flat loads require generation, transmission and distribution investment. Whether those costs reach households depends on tariffs, utility regulation, fuel prices and who funds dedicated upgrades.
Who pays—or gains: Data centers pay direct energy and interconnection charges. Ratepayers can pay when approved system costs are socialized; they can also benefit when large-load revenue spreads fixed costs.
Binding constraint: Speed to power: generation additions, transmission, substations, interconnection studies and consumer-protection rules.
Strongest caveat: National electricity-price movements are not an AI counterfactual. EIA found 2025 wholesale increases were largely driven by natural-gas prices.
What would change the grade: A bill-impact grade must be calculated utility by utility from approved tariffs and cost-allocation orders.
