Turntide Expands LFP Battery Plant in Sunderland for Hitachi
Turntide expands LFP battery output at its Sunderland plant to supply Hitachi Rail tri-mode trains for Grand Central fleet, cutting emissions about 30% by 2028.

SUNDERLAND, UNITED KINGDOM – Turntide Technologies will expand high-voltage LFP battery production at its Sunderland factory to meet growing demand from Hitachi Rail for hybrid and tri-mode trains. The expansion is tied to Arriva Grand Central’s tri-mode fleet, scheduled to enter service in 2028, which is expected to cut fuel consumption and emissions by around 30%. The related fleet investment is valued at approximately £300 million (Source: Hitachi Rail, 2025).
What Is the Full Scope of This Project?
Turntide Technologies confirmed that its Sunderland expansion will increase manufacturing capacity for high-voltage LFP rail battery systems. The high-voltage batteries enable hybrid and tri-mode trains to operate on both electrified and non-electrified lines, reducing fuel consumption, noise pollution, and air-quality impacts. The new battery systems will be manufactured exclusively at the Sunderland plant and fitted to the fleet ordered by Arriva Grand Central, with trains built by Hitachi Rail at Newton Aycliffe. Paul Turbitt, Senior Director of Strategic Operations at Turntide Technologies, will oversee the expansion. Turntide did not disclose the specific capacity increase, capital expenditure, or number of battery systems to be produced.

How Does This Compare to Similar Projects?
The Sunderland expansion proceeds amid a mixed outlook for UK battery manufacturing investment, according to a 2025 industry review that flagged a temporary dip or possible crisis in battery gigafactory projects (Source: BEST Magazine, 2025). For demand-side scale, Canada’s railways reported USD 4.5 billion in capital investment for 2025, with commuter ridership up 22.7% and intercity passengers up 8.6% (Source: Railway Association of Canada, 2025). The UK Battery Strategy also identifies transport electrification as a priority for domestic battery manufacturing capacity (Source: UK Battery Strategy, 2023).
Note: Independent verification of Turntide’s specific production capacity increase, investment amount, and battery unit count was not available at time of publication.
Editor’s Analysis
Localising LFP battery production in Sunderland strengthens the UK’s rail supply chain at a time when partial electrification is emerging as a practical route to lower emissions. The Grand Central tri-mode fleet’s expected 30% reduction in fuel use and emissions, alongside roughly 400,000 additional seats per year on the North East–London corridor, suggests that hybrid traction can deliver both environmental and capacity benefits without waiting for full electrification. Similar efficiency-driven investment in Canada (Source: Railway Association of Canada, 2025) indicates that this UK project is part of a broader global pattern of rail operators using hybrid and bi-mode technology to bridge electrification gaps.
