The 405 MW, lithium-ion “Pueblo Hundido BESS energy storage system and transmission line” project has been submitted for environmental impact assessment (EIA) in Chile’s Atacama region.

No figure was given for the energy storage capacity of the facility.

The site, planned for the commune of Diego de Almagro, will require a 21 km, 220kV electricity transmission line and connection at the Cumbre substation, according to EIA documents.

The site is set to be operating from Oct. 5, 2026 and will have a 25-year project life. It is intended to store electricity generated by unspecified PV plants for reinjection into the grid when required.

The utility-scale BESS is expected to require 200 workers during peak construction and four to eight staff will be required once the site is operational.

Grid-scale

Banking on batteries in Chile The Chilean solar market is booming but as curtailment grows, a hybrid approach to generation is gaining ground. Storage project announcements are coming thick and fast as co-location with wind turbines offers cost efficiency and a smoother generation profile. Meanwhile, new capacity mechanism rules could take Chile one step closer to runaway battery growth.

Natron Energy to build gigawatt-scale sodium-ion battery plant in North Carolina The new planned manufacturing facility will produce 24 GW of Natron’s sodium-ion batteries annually. Natron says its batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable. The plant will be the first double-digit GW sodium-ion plant in the USA.
