New investors complete Stem's corporate Series D second close at $110M

MILLBRAE, Calif. – Stem, Inc., the global leader in artificial intelligence (AI)-powered energy storage, today announced that Ontario Teachers' Pension Plan (Ontario Teachers'), an original Series D investor, has provided the company with a C$200 million commitment to finance the acquisition of AI-driven energy storage projects in the Ontario market.

Stem also announced its second close of Series D financing with an additional US$26 million investment, led by BNP Paribas and Magnesium Capital among other investors. Today's second close brings Stem's total Series D round to nearly US$110 million.

With the expansion of corporate and project equity, Ontario Teachers' will help Stem deliver fully-financed energy storage systems for its customers in Ontario to lower their energy bills and reduce their Global Adjustment, or peak-demand costs. Stem and its partners anticipate the funds to be fully utilized within the next 12 months.

"Our project financing partnership with Ontario Teachers' enables us to further invest in Ontario and present customers with a stable, long-term offer to drive down energy consumption costs," said John Carrington, CEO of Stem, Inc. "Moreover, Stem continues to attract top-tier international asset management interest in our ability to transform electricity grids with vast energy storage networks and our superior artificial intelligence platform."
