Water/Energy Nexus Programs

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.
