IESO asked to suspend surcharge on electricity exports to the U.S.
March 11, 2025
Following the Premier’s statement on March 11, 2025 and the receipt of the new letter from the Minister of Energy and Electrification, the IESO has immediately suspended the implementation of the new Tariff Response Charge on all exports of electricity from Ontario’s electricity market to US jurisdictions. The urgent Market Rule Amendments will remain in place, with the Tariff Response Charge set to $0, subject to further change at the Minister's direction.
The IESO will continue to engage with government and neighbouring system operators including those in the United States.
