GIGA Storage Reaches RTB for 1.4-GWh Albatross BESS

Dutch developer GIGA Storage has achieved a major milestone in the German energy storage market by securing Ready-to-Build (RTB) status for its Albatross battery energy storage project in Lower Saxony. The massive 350 MW / 1,400 MWh (4-hour duration) facility will comprise 264 battery units and connect directly to Amprion's 380 kV Merzen high-voltage substation.

GIGA Storage and transmission system operator Amprion have officially signed the grid connection agreement, marking Amprion's first such agreement for a large-scale battery storage project. Final investment decision is planned for Q4 2026, with construction set to begin in H1 2027 and commissioning targeted for 2028. Albatross is one of three 350 MW / 1,400 MWh projects acquired from Isenau Projects, bringing GIGA Storage's total German portfolio to 1.05 GW and 4.2 GWh.

Construction Begins on 840-MWh Bertikow BESS

In another significant development, Enlight Renewable Energy and ENERTRAG have begun construction on the 200 MW / 840 MWh Bertikow BESS in Brandenburg. The facility will connect to the 50Hertz transmission network and incorporate advanced grid-forming capabilities to support network stability and renewable energy integration.

Enlight Renewable Energy holds a 50% ownership interest in the project, with estimated investment costs ranging between $187 million and $197 million. Commissioning is projected for the first half of 2028.

Accelerating Germany's Storage Pipeline

These developments highlight the immense momentum in Germany's utility-scale BESS sector. With a pipeline of massive projects securing grid connections and breaking ground, Germany is rapidly expanding its long-duration storage capacity. The integration of grid-forming technologies and direct high-voltage connections demonstrates the industry's commitment to building infrastructure that actively supports and stabilizes the national transmission grid.
