According to the statement, the companies are targeting May 2026 COD for the asset, which will be owned by Fuyo General Lease.
RS Asset Advisors has been in charge of development, including site selection and acquisition, grid connection processing, business plan preparation. It will also handle operation and management after commissioning. Fuyo General Lease will select equipment manufacturer and aggregator and be responsible for the commercial operation of the facility.
