The latest industry study from Siemens shows that digital technologies are now central to efforts to strengthen power-grid resilience and accelerate decarbonisation. The Siemens Infrastructure Transition Monitor 2025 canvassed 1,400 senior executives worldwide and distilled three priorities shaping the energy transition: rising clean-energy investment, regulatory and legacy-infrastructure hurdles, and an expanding role for digital tools such as AI, grid software and smart meters.
What the survey found
Respondents reported a shift in policy attention: securing reliable power supplies has overtaken the mere expansion of renewables as a top governmental priority. At the same time, efforts to scale renewable capacity remain high on agendas. The research highlights a paradox familiar to utilities and regulators — while capital is flowing into clean energy, existing networks and uncertain rules are constraining progress.
- Scale of the survey: 1,400 senior executives across industries
- Investment trend: Clean-energy spending has continued to grow
- Technology focus: AI, grid software, smart meters, and emerging tools such as digital twins and autonomous grids
Why digital tools matter
According to the report, improvements in grid resilience will increasingly rely on digitalisation. Technologies that model and manage network behaviour — notably digital twins, which create virtual replicas of physical systems — are identified as key to enhancing operational efficiency, security and sustainability. Similarly, autonomous grid technologies could reduce response times to faults and balance intermittent generation from renewables more effectively.
Siemens points to a broader industry trend: utilities and infrastructure owners are investing not solely in generation capacity but in the software and sensors that make networks smarter. This shift reflects the practical reality that adding more wind and solar projects does not, by itself, guarantee a stable supply unless the grid can integrate and manage them.
Investment context
The report references wider market figures to frame its findings. The International Energy Agency's World Energy Investment report estimated global clean-energy investment reached US$2.2 trillion in 2025, roughly double spending on fossil fuels, underlining where capital is flowing despite persistent operational barriers.
| Metric | Value |
|---|---|
| Executives surveyed | 1,400 |
| Global clean-energy investment (2025) | US$2.2 trillion |
Policy and industry implications
The monitor urges stronger public–private collaboration to overcome regulatory uncertainty and the inertia of ageing infrastructure. For policymakers, the finding that energy security now tops many agendas suggests a potential recalibration of support mechanisms: from subsidies that focus purely on generation to frameworks that also fund grid upgrades and digital systems.
For industry leaders, the message is practical: deploying renewables remains essential, but so is investing in the digital systems that enable those resources to be used reliably. The report signals that technologies such as AI-driven grid management, smart metering and digital twins will be decisive tools in the coming phase of the energy transition.
As governments weigh ambition against the realities of ageing networks, the study offers a clear verdict: expanding clean energy must go hand in hand with digital investment and regulatory clarity if grids are to become both greener and more resilient.
