Frontier Power Acquires 2.8 GWh of Long-Duration Energy Storage Projects in Scotland
UK-based energy developer Frontier Power has acquired a portfolio of long-duration energy storage (LDES) projects totaling 2.8 GWh from Scottish renewable energy developer Apatura. The acquisition significantly expands Frontier Power’s energy storage pipeline and strengthens its position in the UK’s rapidly growing flexibility and storage market. The portfolio comprises four advanced-stage projects located across Scotland, designed to provide large-scale energy storage capacity capable of supporting the integration of increasing amounts of renewable energy. Long-duration storage systems are expected to play a critical role in balancing the grid by storing surplus electricity generated from wind and solar resources and releasing it during periods of high demand or low renewable generation. The acquisition aligns with the UK government’s focus on developing long-duration storage technologies to support net-zero targets, improve energy security, and enhance grid resilience. Once developed, the projects will contribute significantly to reducing renewable energy curtailment, strengthening system flexibility, and enabling a more reliable and sustainable electricity network across the United Kingdom.
Siemens Energy, Neptun Smulders Win Major 2-GW Offshore Converter Contract
A consortium comprising Siemens Energy and Neptun Smulders Offshore Renewables (NSORe) has secured a contract from German transmission system operator 50Hertz to deliver a 2-GW offshore converter system for the North Sea Connector 2 project. The project will connect offshore wind farms in the German North Sea to the national electricity grid and marks the first time offshore converter platforms built to the new 2-GW standard will be manufactured primarily in Germany. The contract covers the construction of one offshore converter platform and one onshore converter station, with discussions ongoing for a second converter system. If fully implemented, the total value of the project for NSORe alone could reach approximately EUR 2.5 billion and create more than 500 long-term jobs, mainly in Germany’s Mecklenburg-Vorpommern region. The project represents a significant step in Germany’s offshore wind expansion strategy. The 2-GW converter technology will enable more efficient transmission of large volumes of renewable electricity from offshore wind farms to consumers, supporting the country’s energy transition, grid modernization efforts, and long-term decarbonization goals
Gresham House Energy Storage Fund and AMPYR Energy Close Financing for Carno 3 Battery Project The Gresham House Energy Storage Fund (GRID) and AMPYR Energy have successfully reached financial close for the Carno 3 battery energy storage project in Wales, marking another significant investment in the UK’s rapidly expanding energy storage sector. The project will deliver 99 MW of power capacity and 198 MWh of energy storage, making it one of the larger operational battery developments in the region. Located in Powys, Wales, Carno 3 is designed to provide critical grid-balancing services, support renewable energy integration, and enhance electricity network reliability. The battery system will store excess renewable electricity during periods of high generation and discharge power during peak demand, helping reduce grid congestion and improve system flexibility. The financing demonstrates continued investor confidence in the UK battery storage market, driven by growing renewable energy deployment and increasing demand for grid flexibility. Once operational, Carno 3 will contribute to the UK’s net-zero ambitions, strengthen energy security, and support the transition to a cleaner and more resilient electricity system.
