Our Projects

Delivering real world solutions for the energy transition

Long‑duration energy storage and advanced grid stability services are vital to the UK’s clean energy future, making renewables more flexible, cutting waste, reducing reliance on imported gas, and helping meet net zero goals. Highview is a critical partner to NESO and the UK’s 2030 energy transition targets.

Our UK programme, with over 16 sites identified, has the potential to power 7.6 million homes, deliver more than £10 billion in infrastructure investment, add £2.7billion to the economy by 2035, and support around 6,200 jobs in construction and the wider supply chain.

Highview is setting a new benchmark for sustainable energy infrastructure, positioning the UK as a global leader in energy storage and flexibility.

Carrington, Manchester - GEN01X

Now under construction at Trafford Energy Park near Manchester, our Carrington facility will be the world’s largest, commercial-scale, liquid air, long-duration energy storage and grid stability platform. Phase 1 of the development, the grid stabilisation component or ‘stability island’, will be operational from 2026. Phase 2, delivering 300 megawatt‑hours of storage and an output of 50 megawatts for six hours, will ultimately enable enough clean, renewable energy storage to serve the needs of 480,000 homes, using existing substation and transmission infrastructure.

Carrington is designed to provide both long‑duration energy shifting and critical grid stability services from a single, zero‑carbon source. Alongside delivering clean power during periods of low renewable output, it will supply synchronous inertia, dynamic voltage support, short‑circuit strength and fast frequency response to strengthen the UK grid. With a 50‑year design life and a strategic location close to major demand centres, Carrington will play a pivotal role in reducing curtailment, improving system resilience, and enabling greater penetration of renewable energy.

Hunterston, North Ayrshire - Millennium Series

Hunterston, in North Ayrshire, Scotland, will be the site of Highview’s first ‘Millennium Series’ hybrid, grid stability and long duration energy storage  platform. Built in two phases, it will operate to provide stability services to the grid from 2027, before the development of its multi-technology storage capacity, combining liquid air storage and lithium-ion batteries for greater operational performance. Hunterston has been designed to provide 3.2 gigawatt‑hours of storage and deliver enough clean electricity to power approximately 650,000 homes for up to 12.5 hours.

Strategically located on the national transmission network, Hunterston will maximise the use of Scotland’s offshore wind resources and help remove grid bottlenecks that currently limit renewable generation. With its scale, strategic location and advanced capabilities, Hunterston will become a cornerstone of the UK’s clean energy infrastructure, unlocking greater value from renewables and supporting the transition to a fully decarbonised power system.

UK Pipeline

Highview now has a growing pipeline of projects, strategically located across the UK, to address key system needs. Future Millenium Series plants will maximise renewable integration, relieve grid constraints, and strengthen energy sovereignty and security. Together, they represent the next phase of our nationwide programme to deliver clean, reliable power at scale and accelerate the UK’s transition to a fully decarbonised grid.

Global Projects

The energy transition is a global challenge, with every nation facing similar needs. Highview is working around the world to address these shared challenges by applying our expertise to the specific requirements of each region, helping governments, grid operators and enterprises accelerate their own transition to net zero.

Australia

Highview is developing a series of base‑load renewable energy power stations in Australia, with planning now underway for three major programmes. In Gladstone, Central Queensland, and Townsville, North Queensland, we are progressing large scale projects combining LDES and short-term battery storage. On the Darwin–Katherine network in the Northern Territory, plans are advancing for an integrated scheme incorporating solar generation, LDES and battery. Together, these initial developments will help Australia meet its target of halving carbon emissions by 2030 and achieving net zero by 2050.

Japan

Our investment partner Sumitomo Heavy Industries (SHI), together with Hiroshima Gas, is developing a grid‑scale LAES demonstration plant in Hatsukaichi, Hiroshima. The 5 MW, four‑hour facility will use waste cold from an adjacent LNG terminal to enhance efficiency and sustainability, showcasing the flexibility of Highview’s modular LAES technology. The plant is scheduled to be operational in 2025.

Global Opportunity

Highview continues to explore opportunities in new markets, with further international projects in development. Our proprietary R2X analytics platform can be rapidly configured to model any grid system in the world, delivering unparalleled insight into its constraints, opportunities and optimal solutions. This enables us to design and deploy high‑impact, cost‑effective projects anywhere, helping customers worldwide unlock the full potential of their energy systems.
