Project at a Glance
The National Renewable Energy Laboratory (NREL) has identified portions of eastern San Diego County, Imperial County and the northern Baja region as some of the top locations in the country to generate electricity from the sun, wind and steam heat from the earth (geothermal power).
To tap into wind resources, SDG&E is proposing infrastructure improvements in the Mountain Empire community located in eastern San Diego County.
These improvements will help deliver renewable energy to customers in SDG&E’s service area.
ECO Project Benefits:
Deliver renewable energy
Reduce emissions and fossil fuel dependence
Improve energy relilability
Facilitate the creation of jobs
Four Components That Comprise This Project:
Delivering renewable power
Constructing a new electric substation along SDG&E’s existing Southwest Powerlink 500 kilovolt transmission line to deliver energy generated from the wind, sun, and steam heat from the earth.
Rebuilding and modernizing the existing 50-year-old Boulevard substation on land adjacent to the current site off Highway 80.
Transferring clean energy
Connecting the two substations with a new 14-mile, lower voltage transmission line to improve reliability and transmit wind power to the Southwest Powerlink.
Linking ECO Substation with the Existing Southwest Powerlink
Connecting to the Southwest Powerlink will facilitate the transmission of renewable energy to SDG&E customers and provide a steady flow of reliable power to the local area.
