Utility Rates and Ratemaking Amendment Act of 2026

This bill requires D.C. utilities to base multiyear rate plans on actual historical costs (not projected future costs) and prohibits mechanisms that let companies later raise rates to cover shortfalls. It mandates refunds for excess profits to customers and requires clear, quantifiable evidence of customer benefits for all rate changes. For major gas infrastructure projects (like pipe replacements), utilities must prove cost-effective alternatives were considered before approving surcharges. These changes aim to prevent further bill increases for D.C. residents and businesses, who have seen average annual costs rise by nearly $600 despite existing protections.
