Mariah del Norte
BHE Renewables · Parmer County · ERCOT
Mariah del Norte is a 230.4 MW wind facility in Parmer County, Texas. EIA's May 2026 inventory lists one operating aggregate generator under Plant ID 59005, with service beginning in November 2016 and BHE Renewables as the registered operator. BHE's current project page reports 230 MW, 96 turbines and 25,024 acres. BHE's page labels 2022 as its 'year operational,' which conflicts with the 2016 EIA service record and is not used as the commissioning date here.
