Challenges and Strategies

Presentation by Martha Davis, Executive Manager for Policy Development, at the CEC Water-Energy Relationship Workshop.

The California Energy Commission (CEC) is examining the state’s “Water-Energy Relationship” through its 2005 Integrated Energy Policy Report (IEPR). Concurrently, the U.S. DOE National Laboratories are studying the "Water+Energy Nexus" at a national level.

Water-related energy consumption already accounts for more than 10% of the state's total energy consumption and peak demand. This energy use sector is expected to grow significantly over the next 5-10 years due to a combination of:

  • Continuing high urban growth;
  • Increasingly stringent water quality rules requiring multi-stage disinfection with high energy technologies such as UV and ozonation;
  • Increasingly stringent wastewater discharge regulations requiring upgrade to tertiary treatment; and
  • Increased reliance on energy intensive drought mitigation measures such as desalination.

On Aprith 8th, 2005 at the Water-Energy Relationship Workshop Martha Davis informed the CEC and concerned stakeholders about IEUA's considerable energy challenges, and the comprehensive energy self sufficiency strategies it is deploying through CALeep and other programs to reduce the impacts of its Water+Energy Nexus on the California electric grid and other ratepayers.

On May 4th, 2005 another presentation was given on the “California Local Energy Efficiency Program (CALeep) Pilot: Inland Empire Utilities Agency."  Learn more about CALeep's approach towards IEUA's pilot project from IEUA's Energy Strategy Best Practices Gap Assessment.
