Powersystems

Powersystems is a UK-based high-voltage electrical engineering company specialising in grid connections and electrical infrastructure for the energy sector. Founded in 1977 and structured as an employee-owned business, it delivers bespoke end-to-end solutions from initial design through installation, testing, commissioning and energisation, typically between 11 kV and 400 kV. As the first Lloyd’s National Electricity Registration Scheme accredited Independent Connection Provider, it has been delivering contestable grid connections at voltages up to 132 kV for nearly three decades. Its integrated capabilities span substations, transformers, switchgear, cable installation, protection panels, terminations and jointing, EPC procurement and project management across industrial, commercial and utility-scale projects. The company focuses heavily on renewable generation and grid infrastructure across the UK. Since 2000, Powersystems has connected over 6.1 GW of renewable energy to the electricity grid, including onshore and offshore wind farms, solar energy, tidal and hydroelectric schemes, as well as generation for short-term operating reserve and combined heat and power. It supports grid stability initiatives such as rotating stabilisers and battery energy storage systems and delivers high-voltage balance-of-plant and grid connections for solar and BESS projects, including the Tolldish Hall Solar Farm (25.2 MW) and transmission-level schemes such as the Coylton 50 MW BESS at 275 kV and the 49.9 MW Bustleholme BESS connected at transmission level. In collaboration with partners, it has connected around 30% of all onshore wind farms in the UK. Powersystems operates from its headquarters near Bristol with a growing presence in Scotland, including a larger Glasgow office that serves as a hub for regional operations and is intended to reduce travel-related emissions. The company underpins its work with ISO-accredited management systems and a strong health, safety and wellbeing culture, evidenced by multiple RoSPA Gold awards and its “Priority No.1” safety brand, and embeds Construction (Design and Management) Regulations 2015 principles from early design through to handover. It positions these practices as central to supporting the UK’s transition to a sustainable, Net Zero 2050 energy system.
