The report discusses infrastructure resilience in a digital world, specifically looking at energy and communications. The case study and references show the importance of wider infrastructure issues, whole systems thinking, societal impact, interdependencies in planning and managing change, and the impacts on legacy infrastructure (particularly hidden services and uses).
Operational communications for energy utilities presents a real challenge. With currently no alternative commercial solutions available to address the industry’s bespoke requirements, there is a need to approach the sign-off and verification from a whole system perspective.
The experience of the gas network operators in overcoming the challenges of losing the ‘hidden uses’ such as local mains power of the PSTN in the digital switchover, has provided clear lessons on risk management when implementing change across systems in isolation.
We have outlined ways to avoid the many issues being experienced by the gas networks and encourage the application of the lessons learned across other legacy infrastructure, systems, and sectors.
