​​On November 19, 2021, the Energy Facility Siting Council approved a Request for Amendment 1 of the Bakeoven Solar Project site certificate, which authorized allocation of previously approved facility components into an amended and two original site certificates for Bakeoven Solar Project, Daybreak Solar Project​, and Sunset Solar Project, respectively.  All three approved facilities now have separate site certificates and certificate holders, yet all share the related or supporting facilities originally approved in the Bakeoven Solar Project​ Final Order.
