Wireless Solution adoption rates are growing in providing communications infrastructure across industries that increases flexibility and opportunity to provide/improve services. Along with increasing take-up rates comes with the challenge of more cyber threats to gain access to data and control assets. National Grid wants to explore the capabilities of wireless technology within a substation environment to identify/support innovative opportunities. While exploring these opportunities, utilities need to be aware of the levels of threat to the transmission network depending on the types of wireless solutions identified. This project will investigate opportunities of using wireless applications and develop the associated cyber threat models to understand impacts on substation security.
To explore how wireless communication, especially considering the emerging technologies, within the substations could realise operational and commercial benefits while also ensuing that the required levels of security are met or surpassed.

  • The current and emerging wireless technology choices that could be suitable for electricity substation needs of today and the future;
  • The relative, technical merits of each option;
  • The security, commercial and operational requirements that need to be achieved;
  • The most appropriate Threat Model;
  • The alignment of the solution with the programmes being undertaken by the Centre for Protection of National Infrastructure (CPNI), including their work with the National Cyber Security Centre (NCSC), Cabinet Offices and lead Government departments and agencies.
