2008 National Town Meeting on Demand Response
June 3, 2008
California Energy Action Plan
The “loading order” identifies energy efficiency and demand
response as the State’s preferred means of meeting growing
energy needs.
The 2008 Energy Action Plan update lists several key DR related
action items:
• Adopt load-management standards to achieve a demand response
infrastructure.
• Utilize advanced metering, tariffs and automated DR infrastructure in
the development of DR programs.
• More progress on dynamic pricing rate design reform for all
customer types.
• Develop DR load impact and cost-effectiveness protocols.
• Modify retail programs to more fully participate in the CAISO’s
wholesale market structure.

 Explore and consider any rate tariffs, equipment,
software, automatic technologies, and other
measures and regulations that would be
appropriate to achieve a price-responsive
electricity market
 Explore the coordination of regulatory authority
of demand response efforts across investor
owned and publicly owned utilities in the state
