Power Continuity for
Infrastructure & Utilities

In infrastructure and utilities, power failure isn’t just disruptive it can halt essential services, breach regulatory compliance, and impact thousands of customers. Shenton Group delivers standby generators from 300kVA to 3200kVA, CHP systems, and 24/7 emergency response, engineered for the demands of water, gas, telecoms, and critical national infrastructure. 

Whether you’re managing pumping stations, treatment plants, gas networks, or remote unmanned sites, our systems keep operations running, protect compliance, and keep communities connected. 

What’s at Risk Without Reliable Power?

Utility and infrastructure providers face unique challenges when power fails:

  • Regulatory Breaches – Missed compliance targets and costly penalties.
  • Remote Site Vulnerability – Unplanned outages in hard-to-reach areas disrupt essential services.
  • Service Interruption – Pumping stations, treatment plants, and critical networks go offline.
  • Customer Impact – Loss of water, energy, or connectivity leads to complaints and reputational damage.
  • Environmental Pressure – Missed sustainability and emissions targets without CHP optimisation.
  • Operational Downtime – Delays to maintenance, upgrades, and emergency response.

Tailored Power Solutions for Utilities & Infrastructure

We engineer and maintain power systems that meet the demands of this sector:

  • Single & Three Phase Generators from 300kVA to 3200kVA.
  • Generator Hire: Ideal for temporary works, upgrades, and emergency response.
  • CHP Systems: Comprehensive maintenance that ensures ultimate uptime, greener energy with reduced heat and electricity costs.
  • Powercall: 24/7 emergency generator rental
  • Prime Power Installations: Long-term solutions for remote or off-grid sites.
  • Full Compliance Support: Designed to meet emissions reduction schemes and regulatory standards, including DEFRA fuel storage requirements.

Power for Water, Gas & Telecoms Networks 

Infrastructure and utility sites each carry distinct risk profiles and your existing case studies already prove this. Making the sub-sector split explicit helps both search relevance and AI extraction:

  • Water & Wastewater — Pumping stations and treatment works can’t tolerate downtime without risking service interruption or environmental breach. We’ve delivered turnkey generator systems for major water utilities, including a solution that removed the need for rental generators entirely and cut cabling costs by a quarter of a million pounds. 
  • Gas Networks — Remote and unmanned gas sites need power systems that run reliably with minimal on-site intervention. We provide ongoing national maintenance support and have installed natural gas generators at remote network sites to keep critical infrastructure operating. 
  • Telecoms & Fibre — Network uptime is the product. We’ve delivered uninterrupted power solutions across 150 fibre network sites, supporting connectivity at scale.
