How Duke Energy Ohio sets its Price to Compare

Duke Energy Ohio doesn't set the PTC arbitrarily. The rate reflects actual costs of procuring electricity for default service customers through a process overseen by the Public Utilities Commission of Ohio.

Duke Energy Ohio runs competitive auctions to buy wholesale electricity. These auctions secure supply from generators at market prices. The utility then passes these costs directly to customers — no markup, no profit on the supply side.

The PTC includes generation costs, transmission charges, and regulatory compliance costs. When wholesale electricity prices rise — as they have with recent capacity market increases — the PTC rises accordingly.

Rate changes occur periodically. The PUCO publishes upcoming rates before they take effect.
