East Bay Community Energy Local Development Business Plan Wind Siting Survey Overview
The East Bay Community Energy's Wind Siting Survey conducted in November 2017 aimed to identify properties in Alameda County suitable for wind energy development. The survey assessed wind speed, hosting potential, and capacity factors, resulting in 110 MW capacity distributed across public and agricultural lands. The report is available for public review with a deadline for comments on December 8, 2017. Explore the potential for wind energy in the East Bay area with this comprehensive survey.

East Bay Community Energy Local Development Business Plan Wind Siting Survey Overview Webinar November 30, 2017 LDBP Project Team: Thomas Yurysta, Optony Special Advisors: Betony Jones & Gary Calderon
Wind Siting Survey - Approach Method: Download and sort Alameda County parcel data Identify large municipal or county owned properties suitable for development Assess average wind speed and hosting potential of these sites Wind stats taken from AWS Truepower When available, expand the sites to include adjacent parcels that appear unused and suitable for development Place turbines in a realistic layout to determine site s hosting capacity 2 MW turbines modeled, a popular middle of the road choice for developers These turbines have typical dimensions of 300 ft rotor diameter and 260 ft hub height Limitations: Properties assessed using satellite imagery only; detailed information not obtained
Wind Siting Survey - Results 110 MW capacity on 19 properties 80 MW on public land / 30 MW on adjacent agricultural land that does not appear to be actively farmed 86 MW inland / 24 MW along bay 28 MW in Mountain House area (highest wind speeds) 21% average capacity factor, though yields from individual sites vary 30% capacity factor for Mountain House sites 12% capacity factor on properties near Livermore and the Fremont Foothills
19 parcels identified for wind development Parcel boundaries highlighted in red 11 distinct clusters, as some parcels are adjacent
Mountain House Cluster Detail 4 Properties. Property type, from top left: Exempt public agency Public utility Agricultural in transition to higher use Agricultural Average wind speed: 6.5 m/s Prevailing wind direction: west-southwest 14 turbines, 28 MW capacity Turbine spacing: 4D perpendicular to prevailing wind 6D parallel to prevailing wind 2D setback from property lines
Thank You The Draft EBCE LDBP Wind Siting Survey Report is posted for public review and comment at: http://ebce.org/local-development-business-plan/ The deadline for submitting comments is: December 8, 2017 LDBP Project Team: Special Advisors: Betony Jones & Gary Calderon
