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.
