The District expended approximately $4.8 million for electricity in 2017, and $5.0 million in 2018. In order to mitigate power costs in the future, the Board requested District staff investigate cost-effective sources of renewable energy to provide long-term sustainable energy source(s) to help offset the cost of operations. After examining potential District owned water and wastewater sites and electricity usage throughout the District, TerraVerde prepared a basis of design report (BODR) for solar power systems at the Deer Creek and El Dorado Hills Wastewater Treatment Plants, and helped staff develop and solicit a request for proposal (RFP) to enter into a long-term power provider agreement (PPA) from multiple solar providers to construct and provide alternate power sources to the District.
