Sectors

Who we work for

Our work spans substations, grid connections and transmission and distribution networks. These are the environments and clients we serve, and the problems we solve in each.

Electricity networks and utilities

Transmission and distribution network operators delivering substation, network and connection projects under regulatory, safety and programme pressure.

Typical challenges

Design capacity that flexes with investment cycles without losing quality
Strict conformance with NGTS, ENA and company-specific specifications
Ageing assets requiring extension, replacement or reconfiguration designs
Connection volumes growing faster than internal engineering resource

What these projects need

Designs that pass operator review first time
Full documentation for adoption, operation and maintenance
Engineers who already know the governing specifications

Relevant services

Renewable energy

Generation developers and operators, including hydropower, connecting projects to distribution and transmission networks.

Typical challenges

Securing a viable grid connection on a programme investors can rely on
G99 compliance from application through to witness testing
Substation and network design that matches the generation technology
Balancing connection cost against long-term operability

What these projects need

Connection applications and studies that stand up to operator review
Substation, cable and protection design for the connection works
Compliance evidence delivered alongside the design, not after it

Relevant services

Battery energy storage (BESS)

Storage developers and operators delivering grid-scale and co-located BESS projects in a fast-moving connection landscape.

Typical challenges

Connection dates that drive the whole investment case
Fault level, protection and compliance questions specific to inverter-based plant
HV infrastructure designed around evolving supplier equipment
Earthing and protection designs for compact, high-energy sites

What these projects need

G99 compliance and connection support for storage
Substation, network and earthing design for BESS sites
Studies that answer operator queries about inverter-based generation

Relevant services

Data centres

Data centre developers and operators whose facilities depend on secure, high-capacity power infrastructure delivered to demanding programmes.

Typical challenges

Large demand connections in constrained network areas
Security of supply as a design requirement, not an aspiration
HV infrastructure that must be maintainable without service interruption
Coordinating utility works with private network design

What these projects need

Demand connection applications and supporting studies
Private HV network and substation design, LV to EHV
Resilient network architectures with documented security of supply

Relevant services

Industrial power systems

Manufacturers and process operators running private HV networks where power quality, capacity and continuity directly affect production.

Typical challenges

Legacy networks carrying loads they were never designed for
Fault levels and protection settings that have drifted from records
Capacity for electrification and expansion projects
Outage windows too short for poorly planned works

What these projects need

Network assessment, studies and reinforcement design
Protection review and coordination across the site
Earthing assessment for changing fault conditions

Relevant services

Independent network operators

IDNOs building and adopting networks where design quality determines adoption value and long-term operating cost.

Typical challenges

Designs that must satisfy both the IDNO and the upstream DNO
Adoption standards applied across varied developer-led projects
Connection programmes driven by development milestones

What these projects need

Network and substation designs ready for adoption review
Studies and records that support the regulatory model
Consistent design standards across a growing asset base

Relevant services

Developers

Property, energy and infrastructure developers for whom the electrical connection is a critical path item with direct commercial consequences.

Typical challenges

Connection feasibility and cost certainty early enough to shape the scheme
Applications and studies the network operator will accept without cycles of rework
Choosing between DNO, IDNO and private wire routes with confidence

What these projects need

Feasibility advice grounded in current network operator practice
Connection applications, studies and design packages from one team
A design counterpart who answers quickly as the scheme evolves

Relevant services

EPC contractors

Engineering, procurement and construction contractors delivering substation and connection works who need dependable design support under contract conditions.

Typical challenges

Design packages that must be right before procurement and mobilisation
Client and operator design reviews on unforgiving programmes
Interface risk between electrical, civil and protection scopes

What these projects need

Construction-ready design with electrical, civil and structural coordinated
Responsive engineering support through construction and commissioning
Documentation that survives contractual scrutiny

Relevant services

Asset owners and operators

Owners and operators of existing HV assets who need senior engineering judgement on the systems they already run.

Typical challenges

Assets outliving their records, settings and original designers
Confidence in protection, earthing and ratings before life extension
Independent scrutiny of third-party designs and modifications

What these projects need

Assessment and studies of existing networks and substations
Independent design review and technical assurance
Remediation and upgrade designs that respect operational constraints
