Lowest effective rates at 1,000 kWh/month

Ranked across tariffs filed since 2020: 5 here, 8% of those on file. Older filings are excluded because they are systematically below what utilities now charge. Of the recent ones, 2 are left out because they price only part of a bill (delivery without the electricity itself, or a single appliance), are open only to some households (such as low-income or electric-vehicle rates), or carry a suspected data error. See methodology. Effective rate includes fixed charges, and availability restrictions may apply.
