Climate Action Plan - Measure E-2.4

 On-Site Renewable Electricity Generation

County operations powered from on-site renewable energy systems will result in energy cost savings, decreased reliance on public utilities, and cleaner air. 
  • 2020 Target: Generate 10% electricity with renewables on-site
  • 2030 Target: Generate 20% electricity with renewables on-site

Renewable Electricity Generated On-Site

Footnote: Data for 2015 - 2017 were extrapolated based on 2014 baseline and 2018 actual data.

How are we doing?

In 2018, renewable energy systems at County sites produced 6,083 megawatt-hours (MWh) of electricity, reaching over half of the 2020 target. This is enough electricity to power 5.5% of the County’s operations and is equivalent to powering 750 homes or removing 913 gasoline-powered vehicles from the road for one year. Producing power onsite has made it possible for the Alpine and Borrego Springs libraries to be certified as zero net energy (ZNE) buildings, meaning they will produce as much energy as they consume! This past year, additional construction of renewable energy systems began at two County facilities including the South Bay Regional Center and the County Operations Center (COC) campus, and more renewable energy projects are slated for development over the next 5 years.

How is this measured?

The Department of General Services tracks the total amount of megawatt hours of electricity generated (MWh) by renewable energy systems at County facilities.

Why is this important?

Electricity generated by renewable sources for use in County operations results in the lowered greenhouse gas emissions. It decreases reliance on utility companies, reduces air pollution, and leads the County toward greater energy independence.

Where are we going?

The County aims to produce 10% of its electricity from on-site renewables by 2020 and 20% by 2030. In 2018, 6,083 MWh were produced on-site at County facilities. Per the County's Zero Net Energy Portfolio Plan, an additional 6 MWh is scheduled for installation on-site at County facilities in the second phase of development by 2030. In addition, every new County building or major alteration must undergo a zero net energy (ZNE) feasibility study, which has led to ZNE designs for the Santa Ysabel Nature Center and the Santee Assessor’s office. ZNE buildings incorporate solar photovoltaic installations and energy efficient design to allow the building to operate completely within the total amount of energy it produces.
