What you actually pay in Crystal City
Constellation's cheapest plan in Crystal City is 14.3¢/kWh all-in. That number is two parts: Constellation's energy charge, plus the Oncor delivery charge — the cost of the poles and wires, set by the PUCT and identical on every plan from every provider on this grid.
At a typical 1,000 kWh month, that's about $143 — including the ~$3.42 Oncor meter charge. Because delivery is fixed, the only lever between providers in Crystal City is the energy charge. Constellation's best rate ranks #12 of 18 providers on the Oncor grid.
