Bristol firm specialises in complex work for renewable energy and storage sectors
A Bristol high-voltage power specialist has been acquired by Cheshire engineering group RSK as it looks to grow its integrated services in the renewable energy and energy storage sectors.
HV Energy Systems (HVES) delivers high-voltage grid connection infrastructure projects across the UK, focusing on technically complex high voltage (33kV – 132kV) and extra high voltage (up to 400kV) connections. Its clients include leading UK renewable energy developers and engineering, procurement and construction businesses.
Its 24-strong team specialises in building modularised and containerised substation solutions, so key project elements can be built and tested off-site to help speed up construction projects.
HVES managing director Craig Steven and technical director Louis Wright founded the business and will continue to lead it. In a joint statement, they said: “We are excited to be joining RSK Group. This partnership will strengthen the service and support we deliver to clients, backed by increased scale and access to a wider network. For clients and colleagues, it is business as usual: you will continue to work with the same team and receive the same level of service, underpinned by the trusted relationships we have built.”
RSK Group chief executive officer Alan Ryder said: “The highly skilled HVES team will add significant value to RSK’s energy transition services and we are very pleased to have them join the group and work alongside some outstanding multidisciplinary colleagues on a range of important energy projects.
“HVES’s capability is particularly valued by renewable energy developers, for whom grid connection is both technically complex and schedule-critical. Delays to energisation can materially affect projects, increasing the importance of delivery certainty and proven technical capability. This makes the HVES team a crucial element in the success of projects that contribute greatly to UK energy security.”
HV Energy Systems was advised by FRP Advisory (corporate finance) and Osborne Clarke (legal).
In 2024, RSK acquired Kendall Kingscott, which has offices in Bristol, Exeter, Cardiff, St Austell, Ringwood and Teddington, and employs more than 200 staff.
