The maximum volume applicable under the framework agreement is 10 GWh.

Lot LOT-0001: Framework agreement for delivery and service of battery storage projects in Germany for Trianel Energieprojekte GmbH & Co. KG
TEP is looking for up to six framework agreement 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 supplier is also responsible for the commissioning of the components it supplies. In addition, a long-term service contract is to be awarded, which includes warranty extensions and is intended to ensure the performance of the system. After successful participation in the participant competition, selected companies will be invited to submit bids on the basis of a project profile including performance requirements and a term sheet. During the bidding phase (following the conclusion of the prequalification process), bidders are required to provide cost estimates for two specific projects. TEP intends to award these specific projects directly to the best bidder(s) upon awarding the framework agreement. However, TEP also reserves the right not to award the projects to be costed, but rather to use them solely as a basis for selection when awarding up to six framework agreements, based on the award criteria. Consequently, there is no entitlement to be awarded a contract. Project No. 1 is located in Mecklenburg-Western Pomerania with a volume of 100 MW / 400 MWh. Project No. 2 is located in North Rhine-Westphalia with a volume of 20 MW / 40 MWh. TEP reserves the right to transfer call-offs or individual orders placed under the framework agreements to affiliated legal entities. This means that TEP will not necessarily be the contracting party for the individual orders placed under the framework agreements. This applies to subsidiaries of Trianel GmbH, of Trianel Flexibilitätsprojekte GmbH & Co. KG or Trianel Energieprojekte GmbH & Co. KG that are yet to be established, as well as the following companies affiliated with TEP: - TEP Amphitrite GmbH & Co. KG - TEP Arkas GmbH & Co. KG - TEP AT GmbH - TEP Bellona GmbH & Co. KG - TEP Epsilon GmbH & Co. KG - TEP Eunomia GmbH & Co. KG - TEP Fortuna GmbH & Co. KG - TEP Irene GmbH & Co. KG - TEP Kalliope GmbH & Co. KG - TEP Lutetia GmbH & Co. KG - TEP Massalia GmbH & Co. KG - TEP Netze GmbH & Co. KG - TEP Thalia GmbH & Co. KG - TEP Themis GmbH & Co. KG - TEP Vesta GmbH & Co. KG - TEP Victoria GmbH & Co. KG - Infrastruktur Kamerland GmbH & Co. KG - TAP Windprojekte GmbH & Co. KG Further information can be found in the procurement documents that will be issued after the conclusion of the participation competition. 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.
