Hitachi Energy and SP Energy Networks (SPEN) have signed a memorandum of understanding (MoU) aimed at supporting Scotland’s transition to a low-carbon energy system through the deployment of sustainable grid technologies.
Under the agreement, Hitachi Energy will supply high-voltage switchgear from its EconiQ portfolio, which avoids the use of sulfur hexafluoride (SF₆)—a greenhouse gas considered to be 24,300 times more harmful to the climate than carbon dioxide. The SF₆-free equipment will be used in two new substations planned for SPEN’s transmission network.
The move is intended to help SPEN contribute to Scotland’s legally binding goal of achieving net zero carbon emissions by 2045. According to the utility, the implementation of EconiQ 420 kV gas-insulated switchgear (GIS) will eliminate emissions equivalent to removing around 27,600 passenger vehicles from the road annually.
“This agreement will help power Scotland’s future and contribute to its net-zero ambitions,” said Andre Gargi, global head of marketing and sales for high-voltage products at Hitachi Energy. “We are at a critical point in the energy transition journey and decarbonising the transmission network is a priority.”
SPEN, which is responsible for transmitting electricity to homes and businesses across central and southern Scotland, said the partnership builds on a long-standing collaboration between the two companies. The deal also supports regulatory commitments made with UK energy regulator Ofgem.
“Decarbonising the grid as we build the transmission network needed for the energy system of the future is a vital step on the journey to net zero,” said Pearse Murray, transmission director at SPEN. “This agreement marks a milestone moment for SP Energy Networks as we continue to invest to upgrade our network while reducing our greenhouse gas emissions.”
The companies said the initiative forms part of broader efforts to modernise the UK’s energy infrastructure, enhance grid resilience, and support the integration of renewable energy sources.
