Coverage %

How we calculate 94.88%

94.88%

Reflects the share of monitored US electricity customers — the customers served by the utilities we track — not the entire US population or every utility in the country.

Formula

coverage-formula.txt

Coverage % = (electricity customers tracked
              across all monitored utilities)
           ÷ (total US electricity customers,
              from EIA)
           × 100
