This follow-on investment in TGE is the first investment made by Great Bay following the recently announced joint venture between certain funds managed by affiliates of Apollo Global Management, Inc.(NYSE: APO) and Altius Minerals Corporation (TSX:ALS) subsidiary Altius Renewable Royalties Corp.to accelerate the growth of Great Bay’s innovative renewable energy royalty business (see press release).The additional investment into TGE is an extension of the current US$30 million royalty investment that Great Bay made in TGE in early 2019, bringing the total royalty capital commitment to US$55 million. As TGE develops and sells individual projects, Great Bay receives a gross revenue royalty on each project for the full life of the project. To date, TGE has sold nearly 1 GW of renewable energy projects subject to the Great Bay royalty program and currently has over 2.5 GW in its development pipeline.

Frank Getman, President and CEO of Great Bay, commented, “We are excited to provide this extension of our current royalty investment based on TGE’s continued success in selling projects and expanding its development portfolio. The Great Bay royalty capital is helping TGE expand and diversify into developing solar energy as well as additional wind energy projects in new regions. We value our partnership with TGE and are thrilled to continue the advancement of a clean energy future through our renewable royalty financing.” “Today Tri Global Energy is one of the top five developers of wind energy in the U.S. because of our commitment to growth and notable partnerships, like that with Great Bay,” said John Billingsley, Chairman and CEO of Tri Global Energy. “We also really believe the future of this country and around the world is renewable energy. And it’s not a question of whether or when we’re going to get there. We’re already here,” Billingsley said.
