Ørsted, a global leader in renewable energy, has made a final investment decision to construct a massive battery energy storage system (BESS) in the UK.
The system, powered by Tesla batteries, will bolster the UK’s energy supply stability and mitigate price volatility.
Strategic Location for Minimal Disruption
The Tesla BESS will be strategically located alongside the onshore converter station for Ørsted’s Hornsea 3 Offshore Wind Farm in Swardeston, Norfolk. This co-location minimizes disruptions for nearby residents and businesses while optimizing construction and operational efficiency.
Significant Capacity and Grid-Balancing Benefits
With a capacity of 600 MWh (and a 300 MW power rating), the BESS can store enough energy to power 80,000 UK homes for a day. During periods of high renewable energy generation, the battery will store excess electricity, releasing it back into the grid during peak demand. This will effectively reduce price volatility for consumers and enhance grid stability.
Ørsted’s Strategic Investment in Energy Storage
The investment in this BESS aligns with Ørsted’s broader strategy to expand its energy storage portfolio alongside its renewable generation assets. The UK, as one of the world’s largest offshore wind markets and home to 12 of Ørsted’s wind farms, presents a prime location for this investment.
One of Europe’s Largest Battery Storage Systems
Upon completion, which is expected by the end of 2026, the Swardeston BESS will be one of the largest in Europe. It represents a significant step forward in the integration of renewable energy sources and the stabilization of the UK’s power grid.
Executive Perspectives
Duncan Clark, Head of UK & Ireland at Ørsted, emphasized the project’s importance in maximizing the potential of renewable energy while providing energy security and value to consumers. Mike Snyder, Senior Director of Megapack at Tesla, expressed excitement about the collaboration and highlighted the value of Tesla’s power electronics in enhancing grid stability.
Expanding Energy Storage Portfolio
Ørsted’s commitment to energy storage is evident in its growing portfolio, with 660 MW (1850 MWh) of storage projects already in operation or under construction in the UK and US. The company is also actively developing a pipeline of over 2 GW of storage opportunities across the UK, Ireland, and the US.
