D Square Energy LLC, a North Bend Wash.-based company that sells, services, and maintains electrical generators that provide backup power for the commercial and industrial markets, has opened an outlet in Spokane Valley.

The new shop occupies 1,400 square feet of leased space at 2224 N. Locust, says Don Dunavant, the company's president. It employs two office workers there now and hopes to add three service technicians and a salesperson to its staff as business ramps up, Dunavant says.

The Spokane Valley branch will serve Eastern Washington, North Idaho, and Eastern Oregon, he says. The company also has sales and service outlets at North Bend and Portland, Ore.

D Square carries a line of generators manufactured by Waukesha, Wis.-based Generac Power Systems Inc. and services all brands, he says.

The Spokane Valley outlet has sold eight 300-kilowatt, natural gas-powered generators that will be installed in the SGL automotive Carbon Fibers LLC plant under construction in Moses Lake, Dunavant says. Recent sales also include two 600-kilowatt, diesel-powered units installed at Lourdes Hospital, in Pasco, and three 150-kilowatt, propane-powered units installed at Eastern Washington University, in Cheney, he says.

Typically, D Square sells generators to electrical contractors who install them for their commercial and industrial customers, he says.

Dunavant says the 21-year-old company services some 4,000 generators annually, and is growing at a fast pace. In 2009, D Square Energy employed 16 people and had revenues totaling $3 million, and the company now employs 23 and is on pace to generate $5.5 million in revenues this year, he says.

Doug Byrd, of Byrd Real Estate Group, of Spokane, and Mark Lucas and Tracy Lucas, both of Spokane-based Kiemle & Hagood Co., handled D Square Energy's lease of the Spokane Valley location.
