Power resilience & UPS solutions for critical infrastructure
For critical environments, a resilient power supply is a baseline requirement for safety and continuity. In line with the Government’s Clean Power 2030 Action Plan, the UK’s energy infrastructure is moving toward decentralised, renewable generation. This means securing reliable supply is becoming more complex.
Secure a reliable power supply
We secure power resilience for critical infrastructure, including healthcare, defence, and transport hubs. Our integrated services span high-voltage grid connections, UPS maintenance and standby generator systems for absolute operational uptime.
Mitie provides the technical expertise to manage this transition. By bringing together specialists in high-voltage engineering, battery storage, and predictive maintenance, we help organisations secure critical energy infrastructure against grid volatility and rising costs.
Mitie’s approach uses a combination of traditional and AI-driven predictive analytics, plus 24/7 remote monitoring through our Technical Services Operations Centre (TSOC). Working together, these to identify and resolve potential faults before they lead to outages.
How we support power resilience for critical infrastructure
Grid connections and high-voltage engineering
Securing power starts at the point of connection. Mitie is a NERS-accredited Independent Connections Provider (ICP). This means we engineer, procure and construct grid connections that were traditionally handled only by Distribution Network Operators (DNOs). Mitie’s expert approach typically results in shorter lead times.
Through our specialised divisions, such as ESM Power and G2 Energy, we design and maintain the high-voltage networks required for large-scale sites. This includes substation design, replacing ageing assets or adding capacity, upgrading transformers to high-efficiency units, and lifecycle management of privately owned on-site networks.

Sustainable energy security through sophisticated storage solutions
On-site generation works best when it isn’t restricted by the time of day.
Solar PV provides the power, while battery backups for critical infrastructure provide the safety net. This allows you to store surplus energy for when it’s needed most.
By reducing your dependency on the National Grid, you have a buffer against sudden price spikes. Your critical energy infrastructure becomes a self-sustaining asset that supports your net-zero goals and your bottom line.
Find new efficiencies through an integrated service offering
Experience the added value of an end-to-end service partner who takes the time to understand your strategic objectives and helps you achieve them. We provide a unified service for critical facilities, from technical engineering and security to power resilience and large-scale decarbonisation.
Our demand-led approach is powered by bespoke technology and AI. This ensures your energy infrastructure remains resilient and compliant 24/7, while allowing you to make budgets go further and focus on your organisation’s core purpose.
Frequently Asked Questions
Helpful information about power resilience for critical infrastructure and how we can help your organisation.
Power resilience is an organisation’s ability to maintain a continuous electricity supply to ensure its critical load is always met, even during grid disruptions.
For critical environments like hospitals, transport hubs and power plants, as well as for large commercial organisations, energy is an invisible but essential utility that keeps everything running. Without it, safety and operations collapse.
Mitie ensures uninterrupted energy supply through integrated engineering, redundancy, and continuous monitoring with the latest technologies. This protects organisations from the significant risks and costs of downtime.
The UK’s energy system is evolving rapidly, with more renewable and distributed sources. While this transformation is critical for sustainability, it also increases complexity in how energy is managed and delivered. Alongside ageing infrastructure and rising demand, this makes resilience more important than ever. Mitie enables organisations to stay in control with on-site generation and storage that smooths variability and protects operations.
Yes. Mitie provides the engineering, maintenance, real-time monitoring and battery lifecycle management that keep UPS and backup power systems for critical infrastructure running.
Critical infrastructure typically requires multiple systems to ensure power resilience. This usually starts with a secure, well-designed grid connection, supported by uninterruptible power supply (UPS) systems. In addition, standby generators provide backup power during extended outages. Increasingly, organisations are adding on-site generation and battery storage to reduce reliance on the grid.
Continuous monitoring and predictive maintenance identify faults before they cause downtime, while regular testing of UPS systems, generators and fuel infrastructure ensures backup power performs reliably.
Mitie provides an end-to-end engineering framework for critical infrastructure. The organisation handles high-voltage grid connections as a NERS-accredited provider and also maintains complex UPS and standby generator systems. Mitie’s Technical Services Operations Centre (TSOC) uses AI to predict equipment failure before it happens. Integrated solar PV and battery storage is offered through Plan Zero, an end-to-end approach to decarbonisation. This helps sites generate their own power while reducing carbon emissions and ensuring long-term energy security.
Yes. Mitie offers high-voltage engineering expertise through the Mitie businesses, ESM Power and G2 Energy. The organisation prioritises hard engineering and data-led intelligence. This protects uptime across critical environments.
