* Contract to build solar power plant in Arizona
* Says plant to be fully operational in 2011
Dec 9 (Reuters) - Solar power firm SunPower Corp SPWRA.O agreed with Iberdrola Renewables to design and build a 20 megawatt photovoltaic plant in Arizona, taking their U.S. collaboration to 50 megawatts within two months.
Iberdrola Renewables -- a unit of Spain's top power utility Iberdrola (IBE.MC) -- is the second largest wind company in the United States, and is now moving aggressively towards the country's solar market.
The Arizona plant is in Pinal county and construction on it began this month, the San Jose, California-based SunPower said in a statement.
The plant, which is expected to create about 200 jobs during construction, will be fully operational in 2011.
Portland, Oregon-based Iberdrola Renewables will own and operate the plant, named Copper Crossing.
SunPower agreed last month to build a 30 MW solar plant for Iberdrola Renewables in Alamosa county, Colorado.
Shares of SunPower, which have risen 11 percent in the last three months, closed at $12.86 on Wednesday on Nasdaq. (Reporting by Krishna N Das in Bangalore; Editing by Roshni Menon)
