Commission rejects
conservation funding settlement
A
settlement among a number of parties to approve an Idaho Power Company application
to shift about $20 million in expenses for conservation programs from the
Energy Efficiency Rider currently on customer bills to base rates and to the
annual Power Cost Adjustment has been rejected by state regulators.
The
Idaho Public Utilities Commission said the issues raised in the settlement are
more appropriately addressed in a general rate case, which is anticipated to be
filed later this year. The commission also expressed concern that shifting some
conservation program expense to other areas may result in a cost allocation to
some customer classes that is not equitable.
Commission
staff and conservation groups supported the settlement, while industrial
customers opposed it. The industrial customers said that while shifting conservation
program expenses from the 4.75 percent efficiency rider now paid by all
customers to other areas may stop further increases in the rider and perhaps
reduce the rider amount, customers would end up paying in other ways. The real
impact, the industrial customers argued, would be the same as increasing the
rider to 6.6 percent.
Parties
that supported the settlement included Idaho Power, commission staff, the Idaho
Conservation League, the Northwest Energy Coalition, the Snake River Alliance
and the Community Action Partnership Association of Idaho, which represents
primarily residential customers on lower and fixed incomes. A group
representing irrigators did not oppose the settlement, but still did not sign it.
Proponents
of the settlement contended that moving some conservation program expenses to
base rates and some to the yearly Power Cost Adjustment puts conservation on
the same level as acquiring generation from traditional supply-side resources
such as coal and natural gas. Including some of that expense in base rates
encourages Idaho Power to continue to pursue conservation programs by allowing
it to earn a rate of return on some investment, proponents argued.
Idaho
Power operates a number of demand-side management (DSM) programs that reduce
demand on the company’s generation needs during peak times of electrical use.
The company also has a number of energy efficiency programs that reduce energy
consumption through the use of more energy efficient lighting, appliances and
industrial equipment. The cost of the demand-side and energy efficiency
programs is recovered from customers through the Energy Efficiency Rider on
customer bills, now set at 4.75 percent.
However,
the revenue raised from the Energy Efficiency Rider is not keeping up with the
cost of demand-side and energy efficiency resources. If changes are not made,
the negative balance in the rider account will be $17 million by the end of
this year and $30 million by the end of 2012. To pay off that negative balance
in one year and continue funding programs at their current level, the rider
would have to be increased from the current 4.75 percent to 7.5 percent of
customer bills. To recover the balance in two years, the rider would have to be
increased to 6.6 percent. The proposed settlement would have reduced the
negative balance in the rider account to zero by early to mid-2012 and could
result later on in a reduction in the rider.
Commission
staff favored the settlement, stating that increasing the rider is “attracting
unwarranted attention and criticism,” resulting in Idaho Power not getting
timely recovery of demand-side costs needed to promote acquisition of
cost-effective conservation programs.
Parties
to the settlement proposed that the expense of three major demand-side programs,
including one for irrigators and one for residential customers with air
conditioners, be shifted to the annual Power Cost Adjustment. They proposed
that expenses related to energy efficiency programs for Idaho Power’s large
commercial and industrial customers be capitalized and included in base rates. Doing so would allow the company to earn a
rate of return on demand-side resources just as it does on supply-side
resources.
The
commission decision to reject the settlement will not mean an increase to the
rider at the present time. Today’s order does allow Idaho Power to include $10
million of the $17 million in the rider account be included in this year’s
Power Cost Adjustment, which the company will file on or about April 15. That $10 million has already been determined
by the commission to be prudently incurred expense. In order for conservation programs
to be found prudent, they must pass three tests showing that customers pay less
for energy than they would if the programs were not in place.
Despite
its rejection of the settlement, the commission said it “recognizes and
appreciates Idaho Power’s commitment in recent years to improve its DSM programs
…”
DSM
programs reduced peak demand by 290 MW in 2009. That’s almost as much reduction
as the power that will be generated by the 330-MW Langley Gulch natural gas
plant being built near New Plymouth. And energy efficiency programs saved 148,000
MWh in 2009, up from 19,000 MWh in 2004.
“Idaho
Power has properly responded to the commission’s directive to pursue all
cost-effective DSM programs, and the results have been significant and
measurable,” the commission said.
