MISO asks to delay tariff start

If you live or do business in the Midcontinent Independent System Operator (MISO) region (Midwest), new rules about how electricity is shared and managed were scheduled to start on June 1, 2025. MISO asked the Federal Energy Regulatory Commission to delay that start so the rules would begin 30 days after the Commission accepts MISO's compliance filing, which means the old rules could stay in place for about a month longer than planned.
