DOE’s cost-recovery proposal would roil U.S. wholesale power markets to keep uneconomic coal and nuclear generation operating. This report finds DOE’s proposal could cost customers up to $10.6 billion per year, with up to $7.3 billion borne by customers in PJM Interconnection. More than 80% of the coal generation subsidy would go to just five companies and nearly 90% of the nuclear generation subsidy costs would go to just five companies.
