A trade group says MidAmerican Energy Co. and subsidiary PacifiCorp rank first among U.S. electric utilities for ownership of wind farms.

The American Wind Energy Association says Des Moines, Iowa-based Mid?American and its western subsidiary own wind farms with a total of nearly 2,000 megawatts of capacity.

PacifiCorp, based in Portland, Ore., owns nearly half of that power.

PacifiCorp also scored third recently for green power programs recognized by the U.S. Department of Energy, which also named PacifiCorp its Energy Star Partner of 2009.

PacifiCorp operates in parts of California, Idaho, Oregon, Utah (as Rocky Mountain Power), Washington and Wyoming.

It also buys wind and biomass power from other operators and is an investor in a solar-energy project in the Mojave Desert.
