The joint venture, SA Grid Solutions, owns Great Kiskadee, a utility-scale battery project under construction in Texas, and anticipates purchasing and advancing additional Apex storage projects in the future. The joint venture is funded 60% by SK and 40% by Apex, which will manage the construction and subsequent operations and optimization of the facility and any to come.
