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.
R.13-12-011 grants the Petition for Rulemaking of the Division of Ratepayer Advocates requesting that the Commission open a Rulemaking proceeding to develop a partnership framework between investor owned energy utilities and the water sector to co-fund programs that reduce energy consumption by the water sector in supplying, conveying, treating, and distributing water.

The Energy Division will be hosting a public workshop on Water-Energy avoided cost of marginal water supplies on July 1, 2014, from 9:00 am to 12:00 pm in the Commission’s Courtyard Room. The purpose of this workshop will be to present a staff proposal on avoided cost calculation methodology and tools. This workshop follows up on the project work discussed at the January and April 2014 workshops. Those wishing to gain more familiarity with this work are encouraged to review materials from the earlier workshops. The draft workshop Agenda and Presentation can be found at these links.

The Energy Division will be hosting a public workshop on Water-Energy marginal water supply and avoided costs on April 25. The purpose of this workshop will be to present a staff proposal on marginal supply and preview the avoided cost calculations methodology and tools. This workshop follows up on the project work discussed at the January 30, 2014 workshop. Those wishing to gain more familiarity with this work are encouraged to review materials from the earlier workshops.
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.
