Comprehensive High Voltage Design and Consultancy
DSSR offers a complete suite of HV services, including network design, load assessments, substation design, cable routing, protection coordination and system studies. Each project is carefully assessed to develop optimised infrastructure solutions that balance capital cost with operational efficiency and long-term maintainability.
We also support clients with grid connections, capacity applications and liaison with statutory authorities, helping to streamline approvals and reduce programme risks. Our experience across complex, multi-phase developments allows us to anticipate challenges early and design solutions that integrate seamlessly with wider building systems.
On the Northumbria project, this holistic approach extended to advanced control systems, including a bespoke energy management and PLC-based control solution to monitor HV and LV distribution and automatically respond to faults or power failures. This level of integration ensures that systems are not only compliant, but intelligent and responsive in operation.
Supporting Decarbonisation and Future Energy Demands
As the built environment evolves, high voltage infrastructure is playing a critical role in enabling decarbonisation. Electrification of heat, electric vehicle infrastructure and renewable energy integration are placing increasing demands on electrical networks.
DSSR supports clients in responding to these challenges by designing scalable HV systems that can adapt to future load increases while maintaining resilience. Our approach considers not only current demand but long-term asset performance, ensuring infrastructure can support Net Zero strategies and emerging technologies.
On large-scale healthcare developments such as Northumbria, this included evaluating energy and carbon reduction strategies alongside HV system design, ensuring that resilience and sustainability are delivered in parallel.
A Trusted Partner for Critical Infrastructure
DSSR has delivered HV solutions across a wide range of sectors, with particular strength in healthcare estates requiring uninterrupted power and complex system integration. Our collaborative working style ensures close alignment with design teams, contractors and stakeholders throughout delivery.
Our work at the Northumbria Specialist Emergency Care Centre highlights our ability to design and deliver highly resilient HV infrastructure within complex, mission-critical environments, overcoming architectural and spatial challenges to achieve a fully integrated solution.
By combining technical excellence with a practical, delivery-focused mindset, we ensure that high voltage systems are not only well-designed but successfully implemented on site.
At DSSR, our High Voltage specialism is about more than compliance—it is about enabling performance, resilience and long-term value for our clients.
Delivering Safe, Resilient and Future-Ready High Voltage Infrastructure
At DSSR, our High Voltage (HV) expertise is centred on delivering robust, efficient and future-proof electrical infrastructure that underpins critical operations across healthcare, education, industrial and commercial sectors. From feasibility through to detailed design and delivery, we provide a fully integrated HV service that ensures reliability, compliance and long-term resilience for our clients’ assets.
Our engineers recognise that HV systems are fundamental to operational continuity, particularly within critical environments such as hospitals where power resilience is essential. We work closely with clients, Distribution Network Operators (DNOs), and Independent Network Providers (IDNOs) to develop tailored solutions that align with project constraints, regulatory requirements and long-term energy strategies.
A key example of this is our work on the Northumbria Specialist Emergency Care Centre, where DSSR delivered full M&E design for a major acute healthcare facility. The scheme incorporated a highly resilient 11kV private network configured as an open ring, distributing power to twin transformer substations across the site, alongside N+1 standby generation connected at HV level to maintain continuity of critical services. This approach demonstrates our capability to design fail-safe, high-performance infrastructure for environments where downtime is not an option.
