The new EPC contract follows the two earlier agreements signed by both companies in December 2010.
The first 18.5MW EPC agreement consists of a 10.5MW solar park in Napanee, home to First Light I and the second project is an 8.5MW solar park located on Thunder Bay International Airport Authority land.
SkyPower closed financing with Deutsche Bank on these projects late last year.
The construction of all three projects is expected to reach completion by third quarter 2011.
Once fully operational, the combined capacity of three power projects is approximately 30MW of nameplate capacity, and the projects are expected to generate approximately 28 million kWh in their first full year of operation and almost 600 million kWh total over the next 20 years.
