Avista Utilities' vista is the Pacific Northwest and the Intermountain West. The utility, a subsidiary of integrated production, transmission, and distribution powerhouse Avista Corporation, provides regulated electricity and natural gas services to residential, commercial, and industrial customers in Idaho, Oregon, and Washington. Avista Utilities provides power and gas services to about 678,000 customers (359,000 electric, and 319,000 gas). It serves power customers with a mix of hydro, natural gas, coal, and biomass generation (with a total capacity of more than 1,790 MW in 2010), and serves gas customers through purchased wholesale gas supply. The company sells excess electricity to wholesale customers.
The utility delivers its services over more than 2,200 miles of transmission line, 18,200 miles of distribution line, and about 7,650 miles of natural gas distribution mains.
Avista Utilities' power generation resources include eight hydroelectric generating plants, and coal, natural gas, and wood-waste combustion plants in Idaho, Montana, Oregon, and Washington. An advocate of green power, in 2010 the company generated 56% of its power capacity from hydroelectric sources. An early pioneer in the use of biomass, in 2008 Avista Utilities celebrated the 25th anniversary of the Kettle Falls biomass power plant, the first facility in the US built by a utility for the sole purpose of generating electric power through the burning wood waste.
Despite the economic downturn the company was able to report a growth in its net income in 2009, thanks largely to a rate increase.
An electric rate increase lifted overall revenues and income in 2010, despite a drop in gas demand and revenues due to a warmer-than-usual winter.
