Brookfield-owned renewable energy developer and operator X-ELIO has partnered with another infrastructure investor NIC to invest in German battery storage developer and system integrator Eco Stor.

Spain-headquartered X-ELIO and Natural Infrastructure Capital (NIC) have struck an agreement with Eco Stor’s existing shareholders, notably the venture capital arm of Norwegian utility A Energi, to invest in the company.

Eco Stor is a battery storage project developer and battery energy storage system (BESS) integrator. After this deal, X-ELIO, NIC, company management and ‘certain existing shareholders’ will continue to invest in progressing the company’s BESS project pipeline in Germany, which totals 6GW.

This does not appear to be a full sell-down by A Energy (through Agder Energi Venture), however, with Eco Stor CEO Trygve Burchardt commenting: “We are very pleased to now announce that X-ELIO and NIC will be investing in ECO STOR together with the continued support from Å Energy.”
