27,253-47,693 homes' annual electricity
ⓘ Arithmetic and sources
27,253-47,693 homes' annual electricity (at 40%-70% load factor)
- Uses biggest size stated for this site = 21 MW.
- Assumed average load = nameplate × 40%-70%.
- Home use = 2700 kilowatt-hours/year.
- No operator discloses load factor; this is a bound, not a measurement.
