It is developed by the local developer Biwo Renovables (Biwo) in the Maule region.
The Environmental Assessment Service of the Chilean region of Maule has favorably assessed the Environmental Impact Statement submitted by local developer Biwo Renovables (Biwo) for the project called the Guallatiti Volcano Energy Storage System (ESA) of 20.64 MW / 82.56 MWh, to be located in the commune of Retiro, province of Linares, in the aforementioned region.
According to the documentation submitted, the project, which will cover a total area of ??1.28 ha, will entail an investment of 45 million dollars, with an estimated start date of construction in September 2025, with completion in March 2026, and an expected useful life of at least until September 2055.
The project is expected to involve the construction, installation, assembly and operation of an electric energy storage system, to be carried out using BESS (Battery Energy Storage System) type batteries with a maximum storage capacity of 40 MWh, a 23/66kV step-up electrical substation, a 66kV single-circuit transmission line and an area for temporary and permanent work facilities.
It is clarified that the batteries "are charged with surplus energy from the National Electric System (SEN), at times when there is greater energy availability, and then discharge the energy to the same SEN, based on the demand of the system."
On the technical side of the storage system, LFP (lithium iron phosphate) batteries, bidirectional converters and protection and control systems are described.
The proposed solution contains six 3.44 MW MT station units with PCS and 24 3.44 MWh Battery container units with a total power of 20.64 MW/ 82.56 MWh at start of life, as anticipated.
Each container has batteries with a capacity of 3440 kWh, a liquid cooling system plus air cooling and a fire extinguishing system.
Last August, Biwo announced an agreement with SUSI Partners to, through its SUSI Energy Transition Fund (SETF), finance the development of a battery energy storage portfolio in central-southern Chile , involving 22 projects with a total expected capacity of 860 MW and up to 3.5 GWh. |
