Energy Infrastructure
Energy infrastructure underpins every part of the UK power system: the substations that step voltage up and down, the transmission lines that carry it across the country, the protection schemes that keep it stable, and the generation assets that feed it. We work with power generators, distribution network operators and asset owners to engineer and maintain the power infrastructure the grid depends on.

What sets us apart in energy infrastructure
We’ve worked on National Grid substation protection upgrades, UAV surveys for EDF Energy at Sizewell C and energy-from-waste plant design for assets exporting directly to the local grid. Power infrastructure projects rarely sit in one discipline. They run across electrical, civil, structural and digital engineering at the same time, and our teams are built to handle that without splitting the scope.
Our power engineering team holds TP144 and TP141 qualifications, which means we can survey, design, manufacture, test and commission protection systems on live National Grid assets without handing off to a third party. We own the work from feasibility through to Factory Acceptance Testing. On programmes with tight schedules, that single line of accountability is what keeps quality and compliance intact.
Grid connections and capacity
Engineering projects through NESO's reformed queue
The UK’s grid connection queue exceeded 700 GW at its peak, roughly four times the capacity the country needs for its Clean Power 2030 targets. Under NESO’s reformed system, a project’s position now depends on technical readiness, not just application date. We work across the full voltage range, from 11 kV distribution connections to 400 kV transmission, and understand what readiness means at each level.
Protection and compliance
Upgrading ageing assets before failure becomes the plan
Relays installed in the early 1990s are reaching the end of their serviceable life across the UK’s transmission network. Leaving key assets unprotected means outages, regulatory non-compliance and stranded capacity. We design, manufacture and commission replacement protection schemes in-house, working to UKBP standards, with our own TP144 site management and TP141 commissioning teams handling each stage.
Asset data and digital capture
Surveys that feed directly into engineering decisions
Accurate asset data is the foundation of any credible maintenance programme or grid connection study. Our digital capture teams use UAV survey, LiDAR and photogrammetry to produce geolocated point clouds, orthomosaics and topographic outputs for transmission corridors and substation sites. That data feeds directly into engineering workflows, giving asset owners a reliable picture of what they’re working with rather than assumptions built on records that are years out of date.
Energy infrastructure in practice
National Grid, Mechanically Switching Capacitor
Morson Praxis were appointed by National Grid to upgrade the out-of-balance protection systems on their Mechanically Switching Capacitor (MSC) units […]
View ProjectBiomass engineering asks more of a design team than most energy disciplines. Fuel handling, thermal conversion, steam generation, emissions control and electrical export all run through the same plant. And a decision in one area changes the constraints in the next. We work across the full lifecycle (feasibility, consenting, detailed design and commissioning). The work is specific and the margins for error are tight. We’ve been doing it long enough to know where both lie.
Energy from waste engineering covers more ground than most clients expect. It spans process design, structural engineering, emissions control and a regulatory landscape that’s changing faster than the technology. We work with clients across the full project lifecycle, designing waste to energy facilities that extract real value from residual waste, from early feasibility through to construction-ready detailed design.
Oil and gas engineering in the UK is operating in a sector that’s contracting at pace. Production from the UK Continental Shelf sits at roughly 20% of its 1999 peak, the government has ended new exploration licensing, and the NSTA projects an 89% fall in output by 2050. None of that makes the engineering easier. At Morson Praxis, we work with operators and Tier 1 contractors who need technical support across the productive life of existing assets and what comes after.
We provide solar energy consultancy in the UK for developers, landowners, investors and EPC contractors working on ground-mounted solar farms, commercial rooftop PV and co-located battery storage. Our teams span structural, civil, electrical and environmental engineering. On solar projects, that breadth matters. The disciplines that shape a viable scheme don’t sit in separate workstreams. They need to work as one.
Wind farm engineering is one of the most technically complex disciplines in the UK’s energy sector. Onshore capacity stands at 15.7 GW and offshore at 14.7 GW, with government targets requiring significant further build-out by 2030. We work with developers, investors and landowners, assessing sites, managing consent, designing turbine foundations and seeing projects through to grid connection and handover.
FAQs: Understanding energy infrastructure
Questions we’re often asked about energy infrastructure.
Energy infrastructure is the network of physical systems that generate, transmit and distribute electrical power. In the UK, it includes high-voltage substations, overhead transmission lines, underground cables, protection and control systems, and the generation assets feeding the network. It operates across two tiers: the high-voltage transmission system managed by National Grid, and the regional distribution networks run by the DNOs.
Energy infrastructure engineering in the UK is the technical discipline covering the design, construction, inspection and maintenance of the power system. It spans substation design, protection scheme engineering, transmission line assessment and grid connection studies. Engineers on National Grid’s transmission assets must hold TP qualifications, including TP144 for site management and TP141 for commissioning, as a condition of working on live infrastructure.
An energy infrastructure consultancy is a specialist engineering firm that provides technical support across the planning and delivery of power network projects. Services cover connection feasibility, protection engineering, substation design, asset surveys, Factory Acceptance Testing and commissioning. One with in-house TP-qualified commissioning teams can carry a project from survey through to energisation under one scope, removing handoff risks that come with multiple contractors.
Power infrastructure investment in the UK is increasing because the grid needs to handle a fundamentally different energy mix. Ofgem’s RIIO-3 determination approved £28 billion across electricity and gas networks from 2026 to 2031. National Grid’s Great Grid Upgrade covers 17 projects to nearly double transmission capacity, driven by the shift from centralised fossil-fuel generation to distributed renewables.
A substation upgrade is a project whose duration varies by scope, voltage level and operator requirements. Protection relay replacements across multiple sites can typically be delivered in months when design, manufacture, Factory Acceptance Testing and commissioning sit within one team. Larger upgrades requiring new switchgear or transformers operate on longer timescales, subject to National Grid or DNO approval.
