Mitie expands battery energy storage and electrical engineering capabilities with addition of former G2 energy team

  • Mitie has welcomed the former G2 energy team, specialists in high voltage electrical and civil engineering, to its business
  • More than 40 members of the former G2 energy team will be joining Mitie, building on its existing energy, decarbonisation and high voltage electrical engineering services
  • Mitie has acquired various assets of the former G2 energy business (which went into liquidation on 3rd July)
  • The announcement follows Mitie’s previous acquisitions of Rock Power Connections and Custom Solar as it continues to grow its energy and decarbonisation capabilities

Mitie is expanding its high voltage electrical and civil engineering capabilities by welcoming the former G2 energy team to its business. Prior to its liquidation, G2 energy supported a wide variety of engineering projects across the UK, including battery energy storage solutions, renewable energy generation such as wind turbines and solar PV, and electric vehicle charging hubs, which capabilities will now be delivered by Mitie.

The addition of the former G2 energy team will also provide Mitie with the capability to provide Contestable Works at voltages up to and including 132kV as well as National Grid self-bay works up to 400kV.  In addition, the team will provide end to end project delivery, from design and installation, to project management and connection onto the grid, as well as proactive and reactive maintenance.

More than 40 members of the former G2 energy team, including its senior leadership, have joined the Mitie Projects business and will support Mitie’s existing capabilities in energy, decarbonisation and high voltage electrical engineering services, complimenting the work of its Rock Power Connections and Custom Solar businesses.

Matt Brailsford, Head of Projects Delivery and Development, Mitie, said:

“As specialists in high voltage electrical, battery energy storage and civil engineering, with experience working on a broad range of projects right across the UK, the former G2 energy team is a fantastic addition to Mitie. With our existing capabilities in energy, decarbonisation and electrical engineering, our new colleagues will add further services to support our customers with their decarbonisation ambitions.”

The joint liquidators are Lee Manning and Simon Jagger of ReSolve, an independent business advisory firm.
