Moving Water More Efficiently
The conveyance, treatment, storage and distribution of water represent nearly a fifth of California's energy consumption, yet water related agencies historically have been underserved when it comes to energy efficiency programs.
The Energy Network is changing that. Four water-related agencies have already enrolled in the program and will bring significant energy savings.
"We have an opportunity to achieve energy savings that we otherwise would not have been able to do with our own resources," said Ryan Gross, General Manager of Running Springs Water District. "We are taking advantage now rather than continuing to defer energy efficiency projects."
The Energy Network is assisting Running Springs with a wide range of projects, from upgrading its headquarters building to mechanical retrofits at its wastewater treatment plant. The projects will improve energy efficiency and reduce operating costs. In total, Running Springs Water District is expected to realize about 400,000 kWh and 2,000 therms in annual savings.
The other three water-related agencies enrolled in The Energy Network are Western Municipal Water District, Western Riverside County Regional Wastewater Authority, and Eastern Municipal Water District.
For these and other water-related agencies in Southern California, energy efficiency is more relevant than ever. The recent shuttering of the San Onofre Nuclear Generating Station means supply will be constrained. Meanwhile, more stringent air quality regulations likely will limit many agencies' ability to use stationary engines as backup power generators in the event of power outages.
With aggressive energy management programs, water utilities can reduce their annual electricity costs by as much as 40 percent. Through the Water Energy Nexus pilot program, The Energy Network also is exploring the confluence of water and energy conservation efforts.
