Project Spotlight
Colbun
8 MW / 32 MWh
Stability and flexibility in the Chilean desert
Energy storage solutions for accelerated decarbonisation
Stability and flexibility for one of the largest power generation companies in Chile
Wärtsilä is providing Colbun, one of the largest power generation companies in Chile, with an 8 MW / 32 MWh energy storage system to accelerate decarbonisation in the region. The battery system will be co-located with Colbun’s 230 MWp Diego De Almagro solar PV facility in the Atacama Desert, an area well-known for its solar radiation.
As Colbun’s first energy storage system, the project will allow the power generation company to integrate additional renewable energy capacity and achieve net-zero emissions. This is also Wärtsilä’s first energy storage project in South America.

Chile has become a leader in renewable energy and the country has one of the most ambitious and economical decarbonisation plans in the world. We are excited to enter the Chilean market to assist Colbun and others to capitalise on the opportunity to realise a 100 percent carbon neutral energy system with market-leading energy storage technologies within the next few decades.
Optimised energy assets with energy management system
Increasing the value of the solar-plus-storage facility
By incorporating energy storage, Colbun can contribute to renewable energy intermittency, or fluctuations in power production, while capturing the full value of its growing portfolio of renewable energy sources.
The Diego De Almagro storage facility includes Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system managed by Wärtsilä’s GEMS Digital Energy Platform.
GEMS is a sophisticated energy management system that co-optimises the utilisation of the energy storage system and the solar PV facility. Through machine learning and data analytics, GEMS determines the most economical periods to dispatch energy to and from the energy storage system, increasing the value of both assets.
