Chile’s National Energy Commission (CNE) has approved the final rules for its 2026/01 Supply Tender, which will procure 2,835 GWh per year of energy and capacity for regulated customers of distribution companies.
The technology-neutral tender does not impose renewable energy quotas but requires bids to be backed by new or existing generation assets using primary fuels other than coal, petcoke, diesel, or No. 6 fuel oil. Natural gas remains eligible.
Battery energy storage systems are explicitly included as eligible assets for meeting supply commitments. Developers can submit existing or planned storage projects, provided they are connected to Chile’s National Electric System (SEN) and have sufficient annual injection capacity.
The tender allows renewable generation and storage projects to participate separately or in hybrid configurations. For storage-backed bids, energy calculations must assume one daily charge-discharge cycle and cannot rely on optimized market dispatch assumptions.
Projects supporting winning bids must demonstrate development progress, including financial close and construction milestones. Suppliers that face delays in reaching commercial operation must secure temporary backup from existing generation or storage assets.
Bids are due by Dec. 4, 2026, with contract awards scheduled for Jan. 13, 2027.
