Solution
To begin the process, we evaluated more than 10 bids for the wind turbine supply, consisting of more than 15 unique turbine generator models, and evaluated multiple balance-of-plant contractors. We also assisted with preparation of the engineerprocure-construct (EPC) request for proposal (RFP) and management of the bid process, helping to lay the groundwork for a cost-effective construction plan.
The project required a detailed wind resource assessment. Our scope also included turbine micrositing to minimize wake-induced losses, limit machine stresses and maximize energy yield; evaluating microwave beam path interference; and providing detailed technology assessments of a preferred wind turbine.
As the dedicated owner’s engineer service team, we developed and maintained the overarching project schedule, which spanned approximately five years, and served as a constant source of background knowledge and guidance for the client until project completion.
Results
The wind farm became operational in 2015, boasting 47 wind turbine generators with 155 megawatts of renewable wind energy capacity — capable of powering up to 65,000 homes. Fulfilling its goal to provide renewable energy to Southern California, Sempra International has a 20-year power purchase agreement with San Diego Gas & Electric. The client is also evaluating a second phase wind farm project, building off the specifications and standards set by this successful renewable project.
