Sunotec Expands German Footprint with New Construction

Sunotec is actively expanding its storage activities in the German market, having commenced construction on a 100 MW / 441 MWh standalone battery energy storage system in Stendal, Saxony-Anhalt. The project reached Ready-to-Build status in the second quarter of 2026, with commissioning targeted for the first quarter of 2027. Sunotec acts as the turnkey provider, covering engineering, installation, and long-term operations and maintenance. The grid connection infrastructure includes a new 110 kV substation being built by WT Energiesysteme GmbH. This project was developed under the SECURSUN framework, a joint venture between Sunotec and securenergy, and adds to Sunotec's impressive portfolio of approximately 6.1 GWh of installed battery storage capacity across Europe.

This expansion is bolstered by significant financial backing. In April 2026, investment firm Blackstone acquired a stake in Sunotec for €250 million to accelerate its European expansion, with the company’s founders remaining majority shareholders.

SPIE Secures Belgian BESS Infrastructure Contract

In Belgium, SPIE Belgium has secured a major contract from HybriX Energy to deliver electrical infrastructure for two significant battery storage projects: Volta in Geel-Heze and Franklin in Massenhoven. Together, these projects feature a combined capacity of 300MWh and a power rating of 70MW, with each project boasting a 35MW rating and a four-hour duration. The facilities will connect to Elia's 150kV transmission network.

Commercial commissioning for the Belgian projects is scheduled for 2027. In addition to the construction and electrical infrastructure delivery, SPIE has secured a comprehensive maintenance agreement lasting up to 20 years, ensuring long-term operational reliability and performance for HybriX Energy's assets. These developments in Germany and Belgium highlight the continued robust pipeline of standalone BESS projects across the European continent.
