Reductions in size of
credits mean increases for Avista customers
A
reduction in the size of two rate credits that customers of Avista Utilities receive
will mean a net increase for both electric and gas customers effective Nov. 1.
Neither of the adjustments increases Avista’s net earnings.
The
Idaho Public Utilities Commission has approved a reduction in the size of the
annual Purchased Gas Cost Adjustment (PGA) credit that will increase gas rates
by an average 4.5 percent, or about $2.53 a month for a customer who uses the
company average of 63 therms per month.
Avista’s
weighted average cost of gas is decreasing from about 49.1 cents per therm to 45.8
cents because of a continued decline in wholesale gas prices. However, the
credit customers got last year – 22 percent – is substantially larger than the
reduced WACOG this year, resulting in a net increase for customers. Avista’s
annual Purchase Gas Cost Adjustment (PGA) goes up or down each year depending
on the year’s wholesale gas and transportation prices.
The
second adjustment is the result of a settlement between the Bonneville Power
Administration and Avista regarding the size of a credit the BPA gives to
residential and small-farm customers of investor-owned utilities in four
Northwest states. The commission has no role in determining the size of the
credit.
Effective
Nov. 1, the credit is reduced from 0.289 cents per kWh to 0.147 cents per kWh.
For a residential customer whose electrical consumption is the company’s
average, the result of the reduced credit is about a $1.42 per month increase.
A 2007 federal court decision reallocated much
of the credit to customers of publicly owned utilities, after the court
determined that customers of investor-owned utilities, like Avista, have been
overpaid during the most recent years the credit had been in place. The settlement
reduces the credit to comply with that ruling and also to settle some
outstanding accounts Avista had with BPA.
BPA
is a not-for-profit federal agency that markets power from 31 federal
hydroelectric dams and a nuclear plant in the Northwest. The 1980 Northwest
Power Act required that residential and small-farm customers in the Northwest
share in the benefits of the federal hydroelectric projects located in the
region. Avista applies the benefits it receives, which usually fluctuate
annually, to customers as a credit on their monthly electric bill.
