Terasen also submits that the energy savings from the EEC expenditures will result in savings with a
present value of almost 10 million gigajoules (“GJs”) over the lives of the various measures
proposed, while fuel switching activity is estimated to result in approximately 2.3 million GJs of
additional load. The anticipated present value of net energy savings is approximately 7.7 million
GJs, not including potential savings arising from Conservation Education and Outreach, Joint
Initiatives or Innovative Technologies, NGV and Measurement program areas. (Exhibit B‐1, p. 10)
Terasen further states that DSM expenditures at current levels would result in cumulative annual
savings of 1.3 million (nominal, rather than present value) GJs by 2016, whereas the proposed
expenditures would result in cumulative annual savings of approximately 6.4 million nominal GJs in
the same time period. (Exhibit B‐1, p. 11)
2.1 Residential and Commercial Energy Efficiency
Terasen developed its budget estimates for Residential Energy Efficiency, Commercial Energy
Efficiency and Residential Fuel Switching based on work done in 2006 in its Conservation Potential
Review (“CPR”). Those estimates were refined by Habart and Associates Consulting Inc. (“Habart”)
as described in Habart’s September 2007 Report (“Habart Report”) provided in Appendix 9 of the
Application. (Exhibit B‐1, p. 52) The Habart Report concluded that total DSM funding of
approximately $35 million over the three‐year period would be required. (Exhibit B‐1, Appendix 9,
p. 23)
Terasen states that “[t]he key finding of the CPR was the Achievable Potential” which is a measure
of savings which could realistically be achieved within the study period. (Exhibit B‐1, p. 45) The
Achievable Potential from the CPR is outlined in the table below:
