Southern California Edison and ProLogis

  • Southern California
  • 90 MW Aggregate
  • Southern California Edison (SCE)

COMPLETED: Expected in 2012
CLIENT: ProLogis, Inc.

Project Summary

These unique solar projects are part of a 90MWp portfolio spread across 25 individual rooftops. Owned and operated by Southern California Edison, these rooftop solar electric systems feed the utility side of the meter. The rooftops and buildings are owned by ProLogis, the leading owner, operator and developer of industrial real estate globally. All 25 of these photovoltaic systems are among the largest rooftop solar systems in the world.

Blue Oak Energy Scope

Full scope engineering and overall project engineer of record for complete construction documents. Blue Oak Energy also performed construction administration and management for the project’s construction phases.

Project Goals

This project was made possible by the California Renewable Portfolio Standard (RPS) which was established in 2002 under Senate Bill (SB) 1078, accelerated in 2006 under SB 107 and expanded in 2011 under SB 2. The RPS program requires investor-owned utilities, electric service providers, and community choice aggregators to increase procurement from eligible renewable energy resources to 33% of total procurement by 2020.
