As a Europe-wide municipal utility cooperation, Trianel taps the potential of liberalized energy markets by bundling complementary interests in the municipal environment with the aim of strengthening municipal utilities in their competitiveness and thus their independence.

More than 100 municipal utilities are linked to Trianel via subsidiaries and associated companies as well as partnership agreements. The Trianel Group currently has around 15 subsidiaries and associated companies. Founded in 2018, Trianel Energieprojekte GmbH & Co. KG ("TEP"), as a wholly owned subsidiary, consolidates Trianel GmbH"s project development activities in the areas of onshore wind and photovoltaics. The subject of this tender is a framework agreement with up to partners as suitable suppliers for the supply of the core components consisting in particular of battery storage, battery inverter, transformer station and battery management system (BMS) and power plant controller. The actual demand-or the scale of the framework agreements to be awarded-is difficult to forecast, particularly due to the unpredictability of the required battery storage capacity. Based on the estimated demand volumes, the total volume under the framework agreement is estimated to be approximately 8 GWh over the contract term of up to eight years. The maximum volume applicable under the framework agreement is 10 GWh.
