Move reflects alignment in UK and EU cybersecurity requirements and the need to share and scale proven best practices across critical energy infrastructure
The Hague, The Netherlands – 10th June 2026: The European Network for Cyber Security (ENCS) today announces that SSEN Transmission has joined the organisation as an Information & Knowledge Sharing member.
Through its membership, SSEN Transmission will engage with ENCS’s network of European transmission and distribution system operators (TSOs and DSOs), accessing collaborative research, technical documentation and knowledge-sharing activities, including workshops and security roundtables. This will support its focus on areas such as testing and operational technology (OT) security operations, as ENCS works with its members to address shared cybersecurity challenges across critical grid infrastructure.
SSEN Transmission is responsible for the high-voltage electricity transmission network across the north of Scotland, playing a critical role in maintaining the reliability of the UK’s power system. Its new ENCS membership will strengthen collaboration between UK and European energy operators at a time when regulatory requirements across both regions place emphasis on cybersecurity best practices and the deployment of secure systems.
This reflects the scale of the threat landscape: in the UK, the National Cyber Security Centre reported 204 nationally significant cyber incidents in the 12 months to August 2025 in its latest annual review, a 130% increase on the previous year, including incidents affecting essential services and critical infrastructure.
“Cybersecurity is a shared challenge across Europe’s energy sector, and collaboration is fundamental to staying ahead of evolving threats,” said Anjos Nijk, Managing Director of ENCS. “Across both the UK and EU, regulatory frameworks place clear requirements on investment in robust security practices and secure systems. We are pleased to welcome SSEN Transmission to ENCS and strengthen cooperation across the sector.”
Iain Dougan, Head of Operational Technology and Cyber at SSEN Transmission added: “Joining ENCS provides an opportunity to collaborate with peers across Europe at a time when regulatory expectations around energy network cybersecurity continue to evolve. With the growth journey that SSEN Transmission are undertaking it is vital that we look beyond just our UK peers to ensure we are tapping into best practice across the continent to solve the shared problems and escalating cyber threats that we face as operators of essential services.”
About ENCS
The European Network for Cyber Security (ENCS) is a non-profit membership organisation that brings together critical infrastructure stakeholders and security experts to deploy secure European critical energy grids and infrastructure. Founded in 2012, ENCS has dedicated researchers and test specialists who work with members and partners on applied research, defining technical security requirements, component and end-to-end testing, as well as education & training. ENCS uses its network in academia, government and business to provide cyber security solutions and counsel dedicated to the needs of national Distribution System Operators (DSO), Transport System Operators (TSOs) and regulators.
About SSEN Transmission
SSEN Transmission is responsible for the electricity transmission network in the north of Scotland, maintaining and investing in the high voltage 132kV, 220kV, 275kV and 400kV electricity transmission network.
Their network consists of underground and subsea cables, overhead lines on wooden poles or steel towers, and electricity substations. It extends over a quarter of the UK’s land mass, crossing some of its most challenging terrain.
SSEN Transmission’s priority is to provide a safe and reliable supply of electricity to our communities. They do this by taking the electricity from generators and transporting it at high voltages over long distances through our transmission network for onwards distribution to homes and businesses in villages, towns and cities.
