The Retail Energy Market Consumer Protection Amendment Act of 2026 aims to strengthen consumer protections in the retail electric and natural gas supply markets in the District of Columbia. Key provisions include a price cap for residential electricity and natural gas, set at no more than 110% of the standard offer service, and the ability for residential customers to terminate supply contracts without incurring fees. The bill also holds market participants accountable for compliance with legal requirements and consumer protections, making them liable for violations by their agents or contractors.

Additionally, the legislation revises definitions and introduces new consumer protection measures in existing laws, emphasizing transparency by requiring market participants to disclose standard contract terms on a Commission-approved comparison website. It also imposes new reporting requirements for natural gas suppliers regarding rates, customer subscriptions, and sales volumes, while allowing the Commission to modify or revoke exemptions if they are no longer in the public interest. Contracts exceeding the price cap will be null and void unless amended within 60 days, and certain natural gas supplies are exempt from these new requirements. The Commission is tasked with implementing these changes within 270 days of the act's effective date.
