PHOENIX and SAN JOSE, Calif., Jan. 2, 2013

PHOENIX and SAN JOSE, Calif., Jan. 2, 2013 /PRNewswire/ --Today, MidAmerican
Solar, a subsidiary of MidAmerican Renewables, and SunPower Corp. (NASDAQ:
SPWR) announced MidAmerican Solar's acquisition from SunPower of the
579-megawatt Antelope Valley Solar Projects (AVSP), two co-located projects in
Kern and Los Angeles Counties in Calif. Together, the two combined projects
will form the largest permitted solar photovoltaic power development in the
world and will create an estimated 650 jobs during construction.

"We are pleased to be working with SunPower on this project. MidAmerican
Renewables, a subsidiary of MidAmerican Energy Holdings Company, has a total
portfolio of more than 1,830 megawatts of owned assets, including wind,
geothermal, solar and hydro assets," said Bill Fehrman, president of
MidAmerican Renewables. "We are excited about these projects because they
support our core business principle of environmental respect. We are very
proud to add SunPower technology to our portfolio of projects."

The Antelope Valley Solar Projects will provide renewable energy to Southern
California Edison (SCE) under two long-term power purchase contracts approved
by the California Public Utilities Commission.

"The Antelope Valley Solar Projects mark a historic milestone for the energy
industry," said Howard Wenger, SunPower president, regions. "We are delivering
highly reliable low-cost renewable energy at a very large scale. SunPower is
proud to partner with MidAmerican Solar and SCE, recognized leaders in clean
energy development, bringing critically needed jobs and economic opportunity
to California and helping the state achieve its renewable portfolio

"SCE appreciates the opportunity to work with SunPower and MidAmerican
Renewables to meet California's renewable energy goals," said Nicole Neeman
Brady, SCE's director of contracts, renewable and alternative power.

SunPower developed the co-located Antelope Valley Solar Projects over the last
four years. At the 3,230-acre site, SunPower will install the SunPower^®
Oasis^® Power Plant product, fully integrated, modular solar technology that
is engineered to rapidly deploy utility-scale solar projects while minimizing
land use. The Oasis product uses high-efficiency SunPower solar panels mounted
on SunPower® T0 Trackers, which position the panels to track the sun during
the day, increasing energy capture by up to 25 percent. In addition, SunPower
will be the engineering, procurement and construction contractor and will
operate and maintain the facility via a multiyear services agreement.
Construction of the solar project is scheduled to begin in first quarter 2013,
with the plants expected to be complete by year-end 2015.

AVSP has secured final conditional use permits and has completed full
environmental review pursuant to the California Environmental Quality Act.

According to estimates provided by the U.S. Environmental Protection Agency,
the project is expected to offset more than 775,000 tons of carbon dioxide
emissions per year, which is equivalent to removing almostthree million cars
from California's highways over 20 years of the plant's operation.

MidAmerican Solar's projects also include the 550-megawatt Topaz Solar Farms
in San Luis Obispo County, Calif., and a 49 percent ownership interest in the
290-megawatt Agua Caliente solar project in Yuma County, Ariz.

"We are pleased to be working with SunPower on this development and look
forward to establishing a mutually beneficial relationship with Southern
California Edison as our customer for energy generated by this project. As we
have done at our other solar project locations, we will work hard to establish
positive and productive relationships with community and county neighbors and
stakeholders," said Paul Caudill, president, MidAmerican Solar.

SunPower has more than 1,000 megawatts of solar power plants operating
worldwide, including the first 130 megawatts of the 250-megawatt California
Valley Solar Ranch, which is under construction in San Luis Obispo County,
