Black Diamond Power Co Electricity Rate per kWh (2024 EIA Data)
Investor Owned|EIA utility 1764|West Virginia|Bundled
In 2024, Black Diamond Power Co's residential customers paid an average of 15.35 cents per kWh: $5.0 million of revenue over 32,418 MWh of sales across 3,479 bundled residential customers, as reported to EIA on Form 861.
How the 15.35c figure is calculated
15.35c/kWh = $4,976k revenue / 32,418 MWh x 100. This is EIA's average realised price for 2024: everything Black Diamond Power Co billed its residential customers (energy, delivery, fuel and rider charges, fixed charges) divided by the kilowatt-hours it sold. It is not a tariff rate, and a 2024 annual average will differ from a current bill. For a 1,000 kWh month at this average, the energy cost works out to about $154 before taxes.

Method: cents per kWh = revenue (thousand dollars) divided by sales (megawatthours), times 100. Customer counts, sales and revenue are the utility's own annual survey responses by state and sector. Bundled = energy plus delivery from one utility; delivery-only = the wires charge for customers who buy energy from a competitive supplier; energy-only = a competitive supplier's energy charge without delivery. County lists come from the EIA-861 Service Territory file; territory centroids used for "nearby utilities" are unweighted means of Census 2023 county centroids.
