The technology-neutral tender excludes coal and other high-emission fuels while allowing solar, wind, hydro and battery storage projects to participate individually or in hybrid configurations.
Chile’s National Energy Commission (CNE) has approved the final terms of the 2026/01 Supply Tender, which will contract energy and capacity to serve regulated customers of distribution companies. The tender includes two blocks totaling 2,835 GWh per year once fully implemented and establishes conditions that facilitate participation from renewable energy projects and storage systems.
The tender does not require awarded energy to come exclusively from renewable sources and does not set technology-specific quotas. However, all bids must 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 under the tender rules.
Backup facilities must be connected to Chile’s National Electric System (SEN), have sufficient capacity to meet contracted energy obligations, and be authorized to participate in the short-term electricity market. Bidders may rely on existing facilities, new projects, or a combination of both.
The tender explicitly recognizes energy storage systems as eligible assets for backing supply commitments. Bidders may nominate existing or planned storage facilities, provided they are connected to the SEN and have sufficient annual injection capacity to cover the contracted volume.
