The electrical systems will expand the capacity of the plant up to 102MW and the technical integration will also be used to connect new wind turbines to the grid.
The wind farm is owned by Brookfield Renewable Energy Group and Coram California Development.
Mortenson Construction vice president and general manager Kevin Deters said, "S&C stepped up as an integral team member working with Brookfield, Mortenson and Southern California Edison to efficiently integrate the Coram Wind farm into the windhub substation."
S&C Renewable Energy director Dan Girard said, "Completing interconnection properly and on time is crucial for renewable energy plant owners who otherwise face delays in getting plants up and running or production curtailments."
S&C also constructed two substations, installed 13 miles of 35kV electrical cable, three miles of 69kV underground cable, and two miles of 69kV overhead cable for the project.
S&C Electric Company is a renewable energy integration company.
