300 Lakeside Drive, the landmark office building in Oakland, California that is the headquarters of Pacific Gas & Electric Company (PG&E), has secured $172 million in Commercial Property Assessed Clean Energy (C-PACE) financing. The loan was provided by GreenRock Capital, a leading participant in the C-PACE sector, in conjunction with KeyBanc Capital Markets.
