Definition

What this measures

Total electric net summer capacity, all sectors, from the EIA Monthly Energy Review table 7.7a, series ELGBPUS through the EIA API v2 total-energy route. Net summer capacity is the maximum output a generator can supply during summer peak demand, net of station use. Monthly, million kilowatts.
