Aquila Capital is pleased to announce the signing of the Balance of Plant (BOP) contract with TEOS Energy GmbH and the supply agreement with Sungrow for the 56 MW / 112 MWh Ohlensehlen battery energy storage system (BESS) in Germany.
This milestone represents a cornerstone step in the delivery of the Aquila Capital Energy Transition Fund I’s first investment and confirms the project’s transition into the execution phase. Commercial operation is targeted for early 2027.
Under the agreements, TEOS Energy will be responsible for the engineering and execution of the high-voltage scope and overall Balance of Plant works, while Sungrow will supply the battery storage technology. Together, these partnerships ensure strong technical capabilities, bankable counterparties and high-quality project delivery standards.
The Ohlensehlen project, with a power capacity of 56 MW and an energy capacity of 112 MWh, is designed to enhance grid stability and enable further integration of renewable energy into the German power system. The project reflects ETF I’s value-add infrastructure strategy, targeting grid-scale flexibility assets that support Europe’s decarbonisation pathway. The project will feature Sungrow’s PowerTitan 2.0 Liquid Cooled BESS, a benchmark solution for large-scale grid support and renewable integration.
As the inaugural investment of the targeted EUR 600 million Aquila Capital Energy Transition Fund I, backed by CommerzReal and disclosed in accordance with Article 9 of the EU Sustainable Finance Disclosure Regulation (SFDR), Ohlensehlen demonstrates the Fund’s ability to originate, structure and advance high-quality energy transition assets through to construction and operation.
Nienke Vledder, Senior Investment Director of Aquila Capital Energy Transition Fund I, highlights:
“The signing of the BOP and supply agreements marks a decisive execution milestone for our first ETF I investment. Securing experienced and technically strong partners such as TEOS Energy and Sungrow underlines our disciplined approach to project delivery and risk management. With Ohlensehlen, we are advancing a strategically located flexibility asset that contributes to grid stability while aligning with the Fund’s value-add infrastructure strategy.”
Christian Welz, Country manager DACH of Sungrow Europe, responsible for ESS, emphasises:
“We are truly honored to collaborate with Aquila Capital on this milestone project. Our team remains fully committed to providing customer support at every stage ensuring long-term project success and energy security for our partners.”
Ceyhun Tankir, Business Development Manager of Teos Energy, states:
“Project Ohlensehlen reflects our core strength: combining high-voltage expertise with agile execution to deliver assets that support grid stability. We are proud to partner with Aquila Capital on their first ETF I investment and value the strong alignment in our approach to disciplined project delivery. Together, we look forward to bringing this project into operation and to contributing to the development of future flexibility assets.”
