PORTLAND, Ore. - PPM Energy, ScottishPower's (NYSE: SPI) competitive U.S. energy business, today announced its intention to expand its wind development activities to Canada through its affiliate PPM Energy Canada.

"We have enjoyed great success to date from our gas storage operations in Alberta," said Terry Hudgens, PPM Energy CEO. "We want to build on this success and leverage our impressive track record of wind development and operations from the US into the Canadian market."

PPM Energy Canada's objective is to build a development portfolio and convert this to operational assets. PPM Energy's initial focus will be on the provinces of Ontario, British Columbia and possibly Quebec. PPM sees this as a natural extension of its successful wind business, bringing its industry leading wind development skills and customer focus to Canada where renewable energy is gaining momentum among Canada's utility companies.
