Chile’s Environmental Impact Assessment System has approved a 762 MWh standalone, grid-connected battery energy storage system (BESS) in the commune of Pozo Almonte in Tamarugal province, Tarapacá region.

Project documents indicate the site will require a 475 m, 220 kV power transmission line to connect to the Nueva Pozo Almonte electricity substation.

The 6.5 ha site will feature 152 containerized ST5015kWh-UX-4H lithium iron phosphate (LFP) batteries from Chinese manufacturer Sungrow, each with bidirectional direct current to alternating current (AC) converters.

Some 38 MVS5140-LS containers will house 5140 kVA power transformers to raise voltage from 690 V (AC) to 33 kV. Each of those containers will connect to the underground medium voltage network within the project area.

The estimated start date for the $157.5 million site is on March 2, 2026 and environmental permitting documents indicate an expected project lifespan of 22 years and four months.

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.

Battery energy storage container

Opinion & Analysis

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?
