Oklahoma

Why is it like this in Oklahoma?

Oklahoma has historically had some of the cheapest electricity and gasoline in the country — and both remain relatively cheap, but the electricity cost trajectory is changing. At least 18 data center projects are planned in Oklahoma, with OG&E projecting a 38% generation shortfall by 2035 and PSO already seeking a 15% rate increase on top of a $119.5 million hike approved in early 2025. At the January 2026 baseline, electricity is still the cheaper per-mile option for Oklahoma PHEVs — though Oklahoma's low gas prices and rising electricity costs from data center load growth are steadily narrowing that advantage.

• Oklahoma Corporation Commission approves PSO rate increase

  KOSU / StateImpact Oklahoma · Jan 17, 2025

  The OCC approved a $119.5 million PSO rate increase (reduced from the utility's $218 million ask), raising residential bills for customers in eastern and southeastern Oklahoma — even a partial rate increase narrows the electricity cost advantage for PHEV drivers in PSO territory.

• As electricity demand and investments grow, what's being done to shield Oklahomans from higher monthly bills?

  KOSU / StateImpact Oklahoma · Feb 12, 2026

  PSO is seeking an additional 15% rate increase driven by AI data center load growth, with OG&E also under pressure; sustained upward rate pressure from industrial demand is the key structural risk to Oklahoma's historically low electricity costs for home PHEV charging.

  Oklahoma's data center boom is about to hit the grid — and your power bill

  At least 18 data center projects are planned in Oklahoma, with OG&E projecting a 38% generation shortfall by 2035 and both major utilities planning to pass infrastructure costs to residential ratepayers — the underlying driver of rate increases in a state where cheap electricity has historically made EV charging attractive.
