Arizona Public Service Co. plans to buy 100 megawatts of electricity beginning next year from the High Lonesome Wind Ranch being built 55 miles southwest of Albuquerque, the company said.

The purchase will give APS 190 megawatts of wind capacity. That is enough electricity for about 47,500 houses in APS territory, when the wind is blowing at both the power plants.

The other 90 megawatts of wind energy under contract to APS also come from New Mexico.

The High Lonesome will be owned by a subsidiary of Edison International and is being developed by Foresight Wind Energy LLC, according to APS.

APS does not usually disclose the price of electricity it acquires through contracts, but officials said the cost from High Lonesome was "competitive."

"We believe we have gotten a very good deal for our customers," spokesman Steven Gotfried said.
