Watts Happening?

August 18, 2026
Please find below our latest issue of Watts Happening?, a market update highlighting key developments across power markets. Our analysis is based on public data and reflects our current views.

Market Update: Retail Power Prices Are Rising and Households Are Paying the Price
Power prices are climbing nationwide, and residential customers are bearing the brunt of the increase.

By the Numbers (Over the Past Three Years):
  • 43 of 49: US markets with higher residential prices
  • 41 of 49: US markets where the residential premium increased
  • 13 of 14: PJM states with higher residential prices
  • Residential Rate +30%: Illinois residential rate increase (+40% increase in premium for residential vs. industrial power prices)
The Big Picture
Power prices are up across the board, but homes are taking the biggest hit — and state officials are taking notice.
  • National Trend (Widespread Retail Rate Surges): Over the past three years, residential electricity rates rose across nearly every contiguous US market, with D.C., New Jersey, Massachusetts, Vermont, and Illinois recording the sharpest absolute increases.
  • PJM Footprint: 13 of 14 PJM states recorded both higher residential prices and a wider rate gap between households and industrial users.
  • Illinois Outlier: Illinois costs surged past national averages. Residential rates jumped from 16.3¢/kWh (July 2023) to 21.2¢/kWh (July 2026) — a 30.1% increase.
In response, lawmakers in Illinois and across the country are drafting policies to protect households from power inflation and expand local supply.

Households vs. Industry: The Gap Is Widening
This is not a case of industrial power prices dropping.

Nationally, both residential and industrial prices rose by roughly 15%. However, in absolute terms, the residential hike was more than double:
  • Residential Increase: +2.29¢/kWh
  • Industrial Increase: +1.04¢/kWh
Across the Lower 48 and D.C., the household premium over industrial rates climbed 14.7%, moving from 8.54¢/kWh (May 2023) to 9.79¢/kWh (May 2026).

How Battery Storage Helps
Batteries absorb cheap, abundant power during low-demand periods and discharge it back to the grid when demand peaks. This simple function relieves grid strain, improves reliability, and lowers long-term electricity costs for everyone.
