Utility Sales May Drop by Half as Homes Make Their Own Power

Updated on

Utilities in the U.S. Northeast stand to lose as much as half of residential sales by 2030 as customers install solar and battery-storage systems and generate their own power, according to a report by the Rocky Mountain Institute.

Residential and commercial customers who opt for alternatives to traditional, utility-supplied electricity could erode power sales in the region by as much as $34.8 billion, the Snowmass, Colorado-based energy consultant said in the report released Tuesday. Fewer kilowatt-hours sold to customers also will affect utilities’ abilities to raise the estimated $2 trillion that needs to be spent to maintain power grids between 2010 and 2030.
