One of the state’s largest end uses of electricity is in the treatment, heating, and conveyance of water in California. This is known to many as the “Water/Energy Nexus.” The IOUs currently offer many incentive programs in the areas of energy efficiency, demand response, and distributed generation related to the water/energy nexus.
The CPUC recently authorized a series of pilot programs exploring whether energy savings may be realized through water conservation measures. Implicit in this approach is the concept that saving water saves energy. The Energy Division is currently analyzing whether an increase in energy efficiency portfolio emphasis on measures that maximize energy savings in the water sector – such as through leak loss detection and enhancement of water systems efficiency – may be warranted. The Energy Division is also currently considering how cost effectiveness should be analyzed for water/energy nexus programs.
The Energy Division will be hosting a public workshop on Water-Energy Cost Effectiveness on January 30th. The purpose of this workshop will be to present an overview of the Water-Energy Cost-Effectiveness project being conducted for the CPUC by Navigant Consulting in 2014. This project is a result of the Cost Effectiveness Framework proposed by Staff at the Water-Energy public workshop in March 2013. Those who are unfamiliar with this work are encouraged to review materials from the March 2013 workshop.

- The Energy Division hosted a workshop on programs and cost-effectiveness related to the Water/Energy Nexus on March 20-21, 2013, at the CPUC in San Francisco. These workshops were held in response to the most recent Energy Efficiency Guidance Decision, 12-05-015, which gave direction on programs related to the Water/Energy nexus.
