System integrator Intilion will provide 81MWh of its BESS technology for a project in North-Rhine Westphalia, Germany.

Intilion will deliver, install and commission the 81MWh battery energy storage system (BESS) project at the Essentho substation in the Sauerland region, North-Rhine Westphalia, in western Germany.

The BESS solution will comprise battery containers, medium-voltage transformer, switchgear and control units and Intilion will also provide long-term maintenance of the system.

The project is scheduled to go into operation in Q3 of 2026 and is being deployed for client Umspannwerk Himmelreich GbR.

There is next to no publicly available information about any company with that name, which directly translates as ‘Himmelreich substation’, though one of its executives was quoted in Intilion’s LinkedIn post announcing the project (with a picture, shown above).

“The partnership with Intilion ensures the high availability and long-term profitability of the project,” said Dr. Jan Lackmann, Managing Director of the operating consortium.

Umspannwerk Himmelreich appears to be related to the Himmelreich substation, which wind power plant technology firm Enercon is building for the Himmelreich Wind Park.

Intilion said an an experienced direct marketer will manage the project’s charge and discharge in the electricity market.

“The partnership with Intilion ensures the high availability and long-term profitability of the project,” says Dr. Jan Lackmann, Managing Director of the operating consortium.

Intilion is active in the grid-scale and commercial & industrial (C&I) segments in Germany and nearby markets. Its focus has tended to be the latter but the company has started to move into larger project sizes recently, announcing a 65MWh order from utility Primeo Energie in Switzerland around the turn of 2024/25.

Intilion has in the past planned to go public via an IPO but pulled those plans in mid-2023 in light of the weaker capital market environment.

Germany-based BESS integrator Intilion and its parent company Hoppecke have decided not to pursue a public listing because of the ‘current capital markets environment’.

Germany is the largest BESS market in Europe by deployments if you include residential and C&I segments, while its grid-scale market is behind the UK. A massive 215GW solar PV target by 2030 is helping drive deployments, and its grid-scale segment could overtake the UK’s. Recent pipelines have been revealed by owner-operators BW ESS and RheinEnergie.
