Eku Energy launches a major 400MW BESS in Germany

July 5, 2026 — Eku Energy has officially entered the German market with its first battery energy storage system (BESS) project, signaling a significant expansion for the global storage specialist. The company announced the acquisition of the 400 MW / 1,600 MWh Dion BESS in Lamspringe, Lower Saxony, which is set to become the largest BESS in Germany.

This four-hour-duration project stands out for its direct transmission grid connection and advanced black-start capability, enabling faster grid recovery during outages. Eku Energy makes its first major move into Europe’s biggest energy market at a pivotal time, as Germany accelerates its shift toward renewable dominance and grapples with growing grid flexibility needs.

The development-stage project is scheduled for commissioning by the end of 2029. It underscores rising investor confidence in utility-scale battery storage across Europe.

Project Overview

The Dion BESS will deliver 400 MW of power capacity and 1,600 MWh of energy storage, making it one of the most substantial standalone battery projects in the country to date. Located in the municipality of Lamspringe in Lower Saxony, the site benefits from strong grid infrastructure.

Key project highlights include:

• Black-start capability allows the system to restart the grid independently after a blackout.
• Direct connection to the high-voltage transmission network for enhanced response times.
• Lithium iron phosphate (LFP) technology supplied by long-term partner Fluence.

These features position the Dion BESS not just as a storage asset but as a critical grid-forming resource capable of delivering multiple services, including frequency regulation, inertia, and energy arbitrage.

Strategic Significance for Germany

Germany’s energy transition has created urgent demand for flexible solutions to balance variable renewable generation. As coal and nuclear capacity retire, battery energy storage systems play an increasingly vital role in maintaining system stability.

The Dion BESS will enhance energy security by providing rapid-response grid services and supporting faster restoration during disturbances. Its black-start capability is particularly valuable in a system with high renewable penetration, where traditional synchronous generators are diminishing in number.

This project aligns with Germany’s broader goals of expanding utility-scale storage. Industry forecasts suggest the country could require tens of gigawatts of additional BESS capacity by 2035 to manage solar and wind variability effectively. Large, transmission-connected projects like Dion help address grid congestion and unlock greater integration of renewables.

Eku Energy’s Expansion Plans in Germany

Eku Energy is taking a deliberate, long-term approach to its German entry. The company has signed a Development Services Agreement with local developer NION, which will continue advancing the Dion BESS to the Ready-to-Build stage. Eku Energy will provide strategic leadership on design, technology, and overall development.

The company plans to open a dedicated office in Germany in 2027 as it builds a broader project pipeline. Ultimately, this move reflects confidence in the German market and a commitment to establishing deep local roots while leveraging global expertise.

Eku Energy will continue collaborating with Fluence for battery supply, drawing on a proven partnership track record across multiple markets.

Eku Energy’s Global Footprint

With the German entry, Germany becomes Eku Energy’s sixth operational market. The company already manages a robust portfolio, with over 25 GWh of projects in delivery or operation across Australia, Japan, New Zealand, the United Kingdom, and Italy.

Eku Energy distinguishes itself through a long-term infrastructure ownership model. Rather than developing assets solely for sale, the company typically retains projects in its portfolio, combining long-term offtake contracts with merchant market participation for revenue resilience.

This approach has attracted significant institutional capital and supports the company’s goal of mobilizing new investment for the energy transition.

Leadership Comment

Erin Lee, Chief Financial Officer of Eku Energy, said, “Eku Energy’s core strength lies in combining technological expertise with deep commercialisation experience. In our multi-use projects, we combine long-term offtake agreements with the participation of our battery assets in power exchange markets. This expertise in contracts and storage technology delivers greater revenue resilience and visibility for our projects.”

Ownership and Financial Backing

Eku Energy is backed by two major global investors. It is jointly owned by the British Columbia Investment Management Corporation (one of Canada’s largest institutional investors) and a fund managed by Macquarie Asset Management, which oversees A$722 billion in assets.

This high-caliber ownership provides the financial strength and long-term perspective needed for large-scale energy infrastructure development in competitive markets.

What This Means for the Future

The entry of Eku Energy into the German market enhances progress in an industry that is evolving quickly. Financially robust companies with strong tech partnerships are likely to thrive amidst grid connection backlogs. They can also benefit from new revenue models like inertia markets and capacity auctions.

The Dion BESS represents more than a single project; it signals growing international interest in Germany’s storage opportunity. As the country pushes toward ambitious renewable targets, projects like this will prove essential for a reliable, decarbonized power system.

For developers, investors, and policymakers, Eku Energy’s entry sets a benchmark for scale, technical capability, and long-term commitment. The coming years are expected to see increased activity in Germany’s battery energy storage sector, particularly for transmission-connected, multi-hour projects.
