Project Overview

Brookfield proposes to repower the existing Alta Mesa Wind Project. Alta Mesa is an existing 27 megawatt (MW) wind project with 159 turbines located in Riverside County, 11 miles northwest of the City of Palm Springs, on land zoned as Wind Energy (W-E). W-E zoning allows the development of wind energy subject to the approval of a Commercial WECS application. The original project was approved in 1986 and was installed in three phases between 1987 and 1997. Alta Mesa plans to repower the project for up to 39 MW.

What's new

The Alta Mesa repower would remove the legacy turbines and install up to 14 new wind turbine generators. The new wind turbine generators would have a maximum tip height (top of foundation to blade tip at apex) of up to 500 feet. The repower would remain within the existing project boundaries. The transmission line that ties into Southern California Edison’s Substation can accommodate the repowered project therefore would not need to be upgraded. The Alta Mesa Project Repower will undergo environmental review by Riverside County in the fall 2019 and spring of 2020. This will include a review of visual effects, noise effects, road work and a joint project review by the Coachella Valley Conservation Commission for the Coachella Valley Multi-Species Habitat Conservation Plan.
