                    Definitions
• Demand-side management: energy conservation,
  load shifting, peak clipping, valley filling, strategic load
  growth
• Energy efficiency: measures or programs that
  reduce energy use (but provide the same amenity
  level) on a year round basis
• Demand response: measures or programs that shift
  the pattern of energy use from peak to off-peak
  periods




                                                                 3

  efficiency in Appalachia to enhance the
  Region’s economic competitiveness.”

Energy Efficiency Savings
and Spending in Virginia




                            12
    Virginia Utility Energy Efficiency and
            Conservation Savings
•   Virginia ranks low on energy
    efficiency savings originating from
    utility programs as % of total kWh
    sales.
•   In the past, the relatively low cost
    of electricity in Virginia increased
    the payback for efficiency
    programs and made them less
    financially attractive.
•   In 2005, VA utilities ranked no
    higher than 64. Western Mass.
    Electric ranks first.
•   We shouldn’t wait for even higher
    prices to promote addition
    efficiency and conservation efforts.


                                             13
Energy Efficiency and Conservation
             Spending
• On average, the Top 20 energy efficiency utilities in
  the US spend 2.75% of annual electric utility revenues
  on energy efficiency programs
• Virginia Electric Power Company and Appalachian
  Power spent about 0% on energy efficiency and
  conservation programs as a percent of 2005 annual
  retail revenues
• Utilities are now starting pilot energy efficiency
  programs

Recommendation from 2007 Virginia
         Energy Plan.
 • Subject to the outcome of the 2007 State Corporation
   Commission energy conservation and demand-control
   study, the Commonwealth, in cooperation with electric
   utilities and energy-efficiency service providers, should
   initiate an aggressive set of actions to expand use of
   energy efficiency, conservation, and demand
   management to offset electric demand and use. Energy-
   efficiency and conservation activities, or program
   portfolios, should address all customer classes and
   income levels.

The Call For Demand Response
 The Energy Policy Act of 2005, for the first time, makes it
    federal policy to endorse demand response and encourage
    states to pursue this technology. The legislation states:
  “It is the policy of the United States that time-based pricing
   and other forms of demand response, whereby electricity
   customers are provided with electricity price signals and the
   ability to benefit by responding to them, shall be
   encouraged, the deployment of such technology and devices
   that enable electricity customers to participate in such pricing
   and demand response shall be facilitated, and unnecessary
   barriers to demand response participation in energy capacity
   and ancillary service markets shall be eliminated.”




                                                                      26
      Demand Response

 Takes load off the grid during times of
  peak electrical demand
 Is becoming a popular program option in
  an evolving electricity market
 Programs are currently offered through
  PJM
 Programs provide cost savings
  opportunities to consumer
 Programs face regulatory and
  institutional challenges
 Technology challenges associated with
  deployment are being overcome

Role of Consumer Education

• Increase awareness of energy efficiency and Energy Star
  logo
   – TV, radio and newspaper advertising
   – Newsletters and bill stuffers
   – Web site information
• Provide information
   – Life-cycle costs, safety, where to purchase energy efficient
     equipment
• Change behaviors
   – Purchasing decisions (buy Energy Star)
   – Move closer to work


                                                                    29

       Energy Savings: approximately 15% of total energy use

                                                                                31
658 Schools in New York State
• 658 schools in 140 districts in New York participated in the New
  York Energy Smart Schools Program.
• Hundreds of building engineers and facilities staff were trained to
  maintain and improve school buildings, providing a safe, healthy,
  and energy-efficient environment for learning.
• More than 15 percent of New York State public schools have
  taken advantage of these benchmarking and modeling tools, and
  have achieved significant results by implementing recommended
  improvements.
• Participating schools have lowered their energy
  consumption by an average of 19 percent

                Summary
• Detailed evaluations show that government
  facilities can attain significant energy and
  money savings with energy efficiency programs
• Annual energy savings in the range of 10% to
  20% are common
• There are many programs available now to help
  government facilities save energy
• Utilities in Virginia are launching new pilots
• Rising energy prices have made energy
  efficiency programs much more imperative!
