ProLogis, a global provider of distribution facilities, has signed new leases for roof space totaling 4.8 million square feet and a system totaling approximately 25MW to mark the beginning of second phase of its 100MW solar project with Southern California Edison (SCE).

The lease agreement that covers 4.8 million square feet of roof space across eight buildings is part of a master agreement that ProLogis signed with SCE to provide up to 100MW of PV installations to the utility through its rooftop solar program.

As per the agreement, SCE will own and operate the system, and feed all the generated power directly into the utility’s electrical system to serve its customers, while ProLogis will act as the site host and provide development management services.

Construction on the project will commence this fall, increasing ProLogis’ total partnership with SCE to 38MW of solar energy, including installations from the first tranche of this master agreement and a pilot project completed in 2008.

ProLogis vice president of renewable energy Drew Torbin said that with these projects underway, the company has now doubled its global renewable energy portfolio from 25MW to approximately 50MW.

“As we approach our 100MW goal with SCE, we’d like to extend our appreciation to the utility for our longstanding partnership and for the joint synergies we have in advancing rooftop solar as one of the best ways to generate utility-scale, clean power,” Torbin said.
