How rates work: The per-kWh rate shown is the all-in price at 1,000 kWh of monthly usage — TDU delivery and base fees included. Many plans have bill-credit thresholds or minimum-usage fees that shift the effective rate by 1–3¢/kWh up or down. Run your real ZIP and usage through the compare-plans tool to see what you'll actually pay.
