can supply 11,850 people/day

Sources: Based on information from the Energy Information Administration, National Energy Technology Laboratory, and U.S. Geological Survey. Annual emission offsets based on 265 MW wind project offsetting coal (0.90 ton/MWh) or natural gas-fired generation (0.50 ton/MWh), using the estimated annual generation from the Ocotillo Wind facility and accounting for regular turbine maintenance. Water conserved compared to coal-fired generation (541 gallon/MWh) or natural gas-fired generation (180 gallon/MWh) source American Wind Energy Association.
