Grid & HV Power for Data Centres
Commercial Governance from Grid Connection Strategy to Energisation.
We provide specialist cost and commercial leadership for HV power infrastructure serving data centres, covering contestable and non-contestable scope.
Our focus is simple: ensure power delivery remains buildable, affordable and programme-secure from Grid Offer through to Energisation.

Scope of Expertise
- Reinforcement works and upstream interface scope
- Statutory coordination with DNOs, IDNOs and network stakeholders
- HV cable routes, ducting, jointing and cable systems
- SEDs (Special Engineering Difficulties) and protection interface approvals
- Primary and Secondary Substations (400kV, 275kV/220kV, 132kV/66kV/33kV/11kV
- Site constraints (third-party assets, easements, crossings and access restrictions)
How We Protect Cost & Programme Certainty
- Define the commercial delivery model and procurement route
- Establish clear contestable / non-contestable demarcation
- Identify constraints, diversion requirements and third-party risks early
- Align energisation milestones with outage windows and SED approvals
- Integrate long-lead equipment and OFCI strategy into critical planning
- Maintain cost governance and structured change control
Key Deliverables
- Contestable / Non-Contestable scope split and diversion strategy
- Baseline HV cost model with risk, contingency and defined escalation
- Detailed cost plans for routes, substations, diversions and enabling civils
- Constraint and outage risk allowance clearly identified
- Tender evaluation and procurement recommendations with live benchmarking
- Ongoing cost reporting and cost-to-complete forecasting through to energisation
Value Delivered
- Early visibility of constraint and diversion cost exposure
- Reduced programme risk linked to outages and statutory approvals
- Smarter procurement decisions informed by market benchmarks
- Commercial discipline maintained through to energisation
