We’re proud to announce the successful completion of the Desert Bloom Storage Project in Maricopa County, Arizona.

With 600 MWh of standalone battery energy storage, Desert Bloom represents a significant milestone for Arizona’s energy infrastructure and is the state’s largest standalone energy storage facility.

The project has the capacity to store enough energy to supply the equivalent of 72,000 homes for up to four hours, while supporting the integration of renewable energy and helping strengthen grid reliability as energy demand continues to grow.

As Arizona progresses towards a cleaner and more resilient energy future, projects like Desert Bloom will play an important role in supporting the evolving energy landscape and delivering the infrastructure needed for a more sustainable grid.

A huge thank you to everyone who contributed to the successful delivery of this project — from our dedicated field teams and project managers to our engineers and support teams. Your commitment to safety, quality and excellence was instrumental in bringing this project to completion.

Delivered by Cooke Power Services, part of the H&MV Engineering Group, Desert Bloom demonstrates our continued commitment to delivering critical energy infrastructure across the US through technical expertise, innovation and a safety-first approach.

Another important milestone for our teams in North America — and a project we’re proud to have delivered.

Coalburn 1 is a flagship energy infrastructure project that, upon full delivery, will become the largest operational Battery Energy Storage System (BESS) facility in Europe—marking a major milestone in Scotland’s renewable energy journey and strengthening the resilience of its clean power network.

The project demonstrates engineering excellence at scale, incorporating Scotland’s first precast transformer bund system and closed-loop earthworks, which eliminated the need to import structural fill. Delivered through an ESG-led approach, the project has also protected local wildlife, enhanced biodiversity, and reduced carbon emissions by thousands of tonnes.

With a capacity of 500 MW / 1,000 MWh, Coalburn 1 will enable the safe absorption of surplus renewable generation while providing critical stability and flexibility to a rapidly decarbonising electricity grid. In doing so, it directly supports Scotland’s net-zero ambitions, reduces constraint losses, and strengthens long-duration grid support at a pivotal moment in the energy transition.

Coalburn 1 stands out as a sector-defining development—combining engineering complexity, environmental responsibility, and large-scale innovation to deliver an energy asset of international significance.

On completion, it will become Europe’s largest grid-connected battery energy storage facility, positioning H&MV at the forefront of delivering the infrastructure that underpins the global transition to a resilient, low-carbon energy system.

H&MV Engineering has been awarded the Design & Build contract for Fidra Energy's 𝐖𝐞𝐬𝐭 𝐁𝐮𝐫𝐭𝐨𝐧 𝐂 𝟓𝟎𝟎𝐌𝐖 𝐁𝐚𝐭𝐭𝐞𝐫𝐲 𝐄𝐧𝐞𝐫𝐠𝐲 𝐒𝐭𝐨𝐫𝐚𝐠𝐞 𝐒𝐲𝐬𝐭𝐞𝐦 (𝐁𝐄𝐒𝐒).

West Burton C is a strategically important 500MW (1GWh) battery storage project located in Nottinghamshire, adjacent to the existing West Burton B power station. The project forms part of Fidra's wider energy storage portfolio, supporting the UK's ambition for a decarbonised power system and strengthening energy security. This significant project marks another major milestone in our growing partnership with Fidra Energy and further reinforces our shared commitment to supporting the UK's energy transition.

This award builds on the successful relationship established through the Thorpe Marsh BESS project, one of the UK's largest battery storage developments at 1.45GW (2.9GWh). The continued confidence shown by Fidra in H&MV's capabilities is a testament to the strong collaboration, trust, and delivery focus demonstrated by both teams throughout our partnership. https://www.hmvengineering.com/hmv-engineering-appointed-to-deliver-uks-largest-battery-energy-storage-project-at-thorpe-marsh/

Adding to this success, Fidra recently announced that West Burton C reached financial close, securing £231 million of debt financing, alongside capital already committed by EIG and the National Wealth Fund, enabling the project to move into the construction phase.

We look forward to delivering another world-class energy storage project and contributing to a cleaner, more resilient energy future for the UK.

H&MV Engineering is proud to confirm our appointment as principal designer and contractor for the delivery of the 400 kV grid connection and electrical infrastructure for the Thorpe Marsh Battery Energy Storage System (BESS) – the largest of its kind in the UK and among the largest in Europe.

H&MV Engineering is proud to mark the successful first energisation of the Killonan 220 kV G.I.S Substation Upgrade, delivered in partnership with ESB Networks.

The successful energisation represents a significant milestone in the delivery of this complex high-voltage infrastructure project and reflects the close collaboration between H&MV Engineering, ESB Networks, ESB Engineering and Major Projects, project partners and key stakeholders throughout the project lifecycle.

As part of the project, H&MV Engineering was responsible for PSCS and PSDP responsibilities, alongside the full design and build of the civil and electrical works. The scope included the delivery of the 110 kV and 220 kV G.I.S substations, associated buildings and infrastructure, 22 bays of 110 kV G.I.S switchgear, 12 bays of 220 kV G.I.S switchgear, two 250 MVA transformers and 16 HV grid routes, as well as extensive remote-end works across the wider network.

The project required significant coordination across design, civil construction, electrical installation, commissioning and network interfaces, with teams working collaboratively to progress the works through to final commissioning and energisation.

The successful completion of Killonan represents an important achievement for everyone involved and further demonstrates H&MV Engineering’s capability in delivering complex high-voltage infrastructure projects safely and effectively. A huge thanks and well done to the whole project team for their hard work and dedication. A standout result from a standout team. Huge congratulations to everyone involved — your hard work and commitment are what make the difference.

We would like to thank ESB Networks, ESB Engineering and Major Projects, our project partners, supply chain partners and the wider H&MV team for their collaboration and commitment throughout the delivery of this project.

Congratulations to everyone involved in reaching this important milestone.
