Title: Conservation and Energy Efficiency: Recent Performance, Future Potential


1
Conservation and Energy Efficiency Recent
Performance, Future Potential
  • Jeff Schlegel
  • Consultant to the
  • CT Energy Conservation Management Board
  • Connecticuts Energy Future
  • December 2, 2004

2
Background
  • Connecticut Conservation and Load Management Fund
    (CLM) was created by the State Legislature to
    provide cost-effective energy conservation
    programs
  • CLM programs are administered by the electric
    distribution utilities (CLP and UI)
  • Energy Conservation Management Board (ECMB) was
    created by the Legislature to advise and assist
    input review function
  • Department of Public Utility Control (DPUC) is
    responsible for final approval of the CLM
    programs

3
Energy Efficiency (or Energy Conservation)
  • Products, services, or practices aimed at
    reducing the energy used by specific end-use
    devices and systems, by substituting technically
    more advanced equipment or practices to produce
    the same or improved level of service with less
    energy use
  • Energy efficiency is NOT curtailment
  • Benefits customers, the electric system, the
    environment, and the economy
  • CLM also funds load management and supports load
    response (though not addressed in this
    presentation)

4
CLM Expenditures and Benefits
  • 89 million/yr collected from ratepayers
  • CLM expenditures range from about 89 million in
    full funding years (2000-01) to about 60 million
    in recent years (balance was allocated to deficit
    reduction, DPW)
  • 60 MW of energy efficiency resources provided in
    a full funding year
  • Reduces annual load growth by 50-80
  • Energy efficiency is the least cost resource
    .02 to .05 per lifetime kWh, delivered
  • Provides 3 in benefits per 1 invested

CLM Funding
6
Potential for Energy Efficiency
  • Study for the Connecticut ECMB
  • Estimate the achievable cost-effective potential
    for energy conservation and energy efficiency
    resources over the 2003-2012 period in three
    geographic areas
  • Connecticut statewide (CLP and UI)
  • The 52 towns in constrained SW CT
  • The 16 critical constrained towns in SW CT
    (Norwalk-Stamford area)

7
Focus and Scope of the Study
  • Maximum achievable, cost-effective potential (not
    the technical potential)
  • Energy efficiency only (not load management or
    load response)
  • Limited to cost-effective options that are
    commercially available now
  • Residential, commercial, industrial sectors

8
Study Findings
  • Very large energy efficiency potential remaining
    opportunities in all sectors
  • Capturing the achievable cost-effective potential
    for energy efficiency would reduce peak demand by
    13 (908 MW) and electric energy use by 13
    (4,466 GWh) by 2012
  • Would result in (approx.) zero growth in electric
    load from 2003 through 2012
  • Net benefits of 1.8 billion

Capturing Energy Efficiency Potential is Very
Cost-Effective
11
Conclusions
  • Energy efficiency benefits customers, the
    electric system, the environment, and the
    economy 3 in benefits per 1 invested
  • Very large energy efficiency potential remaining
    significant cost-effective opportunities in all
    sectors
  • ISE potential study found similar results
  • Connecticut should increase energy efficiency
    efforts to capture the benefits
