06 May 2026, Aachen, Hamburg \u2013 In Gro\u00df Laasch, south of Schwerin, the Hamburg-based solar and storage specialist greentech has constructed a grey electricity battery energy storage system with a capacity of 27 MWh for municipal project developer Trianel over the past few months. The system was installed alongside a 16 MWp photovoltaic plant, which was also realised by greentech in 2025 and commissioned at the end of that year. The scope of services included engineering, mechanical and electrical installation and commissioning, as well as grid integration and certification \u2014 the latter being particularly complex due to the shared grid connection with an existing PV plant. <\/p>\n
\u201eDer Batteriespeicher in Gro\u00df Laasch ist die erste Graustrom-Anlage im Trianel-Portfolio. Wir sind \u00fcberzeugt, dass PV-Freifl\u00e4chenanlagen ihr volles Potenzial f\u00fcr die Energiewende erst dann entfalten, wenn sie mit einem Speicher kombiniert werden\u201c, erkl\u00e4rt Andreas Lemke, Abteilungsleiter Solar bei Trianel. \u201eDaher denken wir Speicherl\u00f6sungen bereits bei der Projektentwicklung mit und pr\u00fcfen auch bestehende Standorte auf Integrationsm\u00f6glichkeiten. Mit greentech haben wir seit Jahren einen erfahrenen Partner an unserer Seite, mit dem wir dieses Ziel in Gro\u00df Laasch erfolgreich umgesetzt haben.\u201c <\/p>\n
“The battery storage system in Gro\u00df Laasch is the first grey electricity asset in the Trianel portfolio. We are convinced that ground-mounted PV plants can only reach their full potential for the energy transition when combined with storage,” says Andreas Lemke, Head of Solar at Trianel. “Therefore, we factor in storage solutions from the project development stage and also assess existing sites for integration opportunities. With greentech, we have had an experienced partner by our side for years, and together we have successfully delivered on this goal in Gro\u00df Laasch.” <\/p>\n
“We have successfully built and commissioned the first large-scale battery storage system for Trianel \u2014 a true milestone for greentech. We are particularly pleased that, in addition to the turnkey construction, we were also awarded the O&M mandate for the battery system. This allows greentech to strategically expand its capabilities in the direction of BESS and co-location. The smooth construction process and seamless grid integration make me extremely proud of the team involved. We would like to thank Trianel for the collaborative partnership and their trust in working with us to deliver these pioneering projects,” says J\u00f6rn Carstensen, Chief Technical Officer for greentech.<\/p>\n
Beyond Gro\u00df Laasch, further joint PV and BESS projects between Trianel and greentech are already in preparation, with realisation planned over the course of the year.greentech Pressekontakt<\/p>\n
