Altius Minerals Corporation announced that Great Bay Royalties has closed an approximately US$73 million royalty investment with Apex Clean Energy for the 311 MW Coles Wind project in Illinois. Construction of the project began in January 2026 with an expected Commercial Operations Date in H2 2027. The investment represents Great Bay Royalties' largest single asset royalty acquisition to date, diversifying its portfolio of 14 operating royalties.
Brian Dalton, CEO of Altius, highlighted the strong 20-year Power Purchase Agreement (PPA) anchoring the project, noting it reflects the unprecedented demand for new, near-term deployable electricity sources. The royalty structure features higher rates during the initial 10 years to meet base return objectives, stepping down to a lower perpetual gross revenue rate to minimize disincentives for future life extension or production enhancements.
The investment was funded through a combination of GBR cash on hand and new capital contributions from Altius Renewable Royalties Corporation and Apollo. Altius provided approximately US$12.4 million (C$17 million) to ARR to support its share of the GBR capital call contribution. GBR is owned by a joint venture between ARR and funds managed by Apollo Global Management, with an effective 29% interest attributable to Altius.
