Expanding Solar Energy Horizons: SUSI Partners Boosts Battery Storage Capacity in Central-Southern Chile

SUSI Partners, through its SUSI Energy Transition Fund (SETF), is making waves in the renewable energy sector with a groundbreaking investment in battery energy storage. The firm is funding the development of a substantial battery storage portfolio in central-southern Chile, a move that significantly enhances its collaboration with local developer BIWO Renovables (BIWO).

This new venture will see the SETF invest in 22 battery energy storage projects, targeting an impressive total capacity of 860 MW and up to 3.5 GWh. Most of these projects are in advanced stages, with the first expected to break ground in the first half of 2025. This initiative builds on SUSI’s existing partnership with BIWO, which already includes a range of distributed and utility-scale renewable energy projects across the region.

The strategic investment is poised to address Chile’s growing need for energy storage as renewable energy sources become a larger part of the country's power grid. With BIWO securing critical interconnection capacity in key locations, these standalone battery storage systems will provide a cost-effective and swiftly deployable solution to alleviate pressure on transmission networks. Recent updates to capacity market regulations further underscore the growing importance of energy storage solutions.

This milestone reinforces the ongoing synergy between SUSI and BIWO. The partnership has previously focused on distributed generation projects under Chile’s PMGD price stabilization regime and utility-scale hybrid solar PV and battery storage projects. The addition of standalone battery storage is a logical evolution, leveraging the combined expertise of both parties in the sector.

The SUSI Energy Transition Fund (SETF), an evergreen infrastructure equity fund, continues to maintain a diverse portfolio across various energy transition themes. These include clean energy generation, energy efficiency, battery storage, customer energy solutions, and electric vehicle charging, reflecting SUSI Partners' commitment to driving forward the global energy transition.
