The challenge of EHV connections

Extra-high voltage connections — typically 33kV and above — are among the most technically and commercially complex transactions in UK energy infrastructure. They sit at the intersection of Ofgem regulation, National Grid policy, DNO/TO commercial frameworks, and increasingly congested connection queues. A poorly structured application can cost years of delay.

Arcform's connections practice exists to prevent that. We bring together deep regulatory knowledge, hands-on technical expertise, and a commercial perspective that comes from having originated, invested in, and operated these assets — not just advised on them.

What we cover

Connection strategy and route-to-grid assessment for new generation, storage, and demand projects
Feasibility studies and load flow analysis to inform investment decisions ahead of formal application
Grid connection application management — from pre-application through to offer acceptance and agreement execution
Regulatory navigation across Ofgem, NESO, DNO, and IDNO frameworks
Connection offer review, negotiation support, and benchmarking
Technical due diligence for buyers, lenders, and equity investors
Coordination with NESO queue reform processes and the new connections framework

Queue reform expertise. The NESO connections reform programme is restructuring how projects enter and progress through the national queue. Arcform's team understands the new framework in detail and can advise on how to position your project for the best possible outcome under the revised rules.

Our approach

01

Project assessment

We start with a thorough review of your project parameters — location, technology, capacity, timeline, and commercial structure — to understand what you need and when.

02

Options analysis

We model available connection routes, network configurations, and commercial structures to identify the approach that best meets your technical and investment requirements.

03

Application and negotiation

We manage the formal process on your behalf — preparing applications, engaging with DNOs and National Grid, reviewing connection offers, and negotiating terms.

04

Handover and ongoing support

We support transition into construction and, where appropriate, into our ownership and operation services — ensuring continuity from development through to energisation.

Who this is for

Our connections support serves a broad range of clients: renewable energy developers at early-stage feasibility, infrastructure investors conducting technical due diligence, asset owners reviewing their existing connection arrangements, and contractors seeking specialist EHV input to live projects. If your project involves a significant electricity connection, we can help.

02

Network Ownership

Independent, specialist ownership of large-scale electricity networks — providing regulatory standing, long-term asset stewardship, and commercial discipline on behalf of developers and investors.

A different kind of network owner

Many energy projects — particularly large-scale renewables, industrial estates, and multi-tenant campuses — require a dedicated entity to own the on-site or connection network. The choice of who takes on that role has significant long-term commercial and regulatory consequences.

Arcform is built for this. We are an independent, specialist network owner. We are not a DNO with competing priorities, a construction contractor managing assets as a side business, or a fund deploying capital at arm's length. We are owners who take pride in how networks are structured — and who have the regulatory standing, technical capability, and commercial discipline to do it properly.

Ownership services

IDNO network ownership — licence application in progress with Ofgem; pipeline projects welcome ahead of award
Private wire network ownership for generation, storage, and demand-side assets
Asset acquisition and adoption — including adoption of newly constructed networks from developers
Balance sheet structuring and long-term asset management for network portfolios
Regulatory reporting, licence compliance, and stakeholder engagement on behalf of connected parties
Connection agreement management and interface with DNOs and National Grid

IDNO licence in progress. Arcform is actively pursuing its IDNO distribution licence with Ofgem, with a specific focus on EHV-connected industrial and commercial networks. We are engaging with prospective clients now — if you have an upcoming IDNO ownership requirement, early conversations are welcome and will position your project well for when the licence is awarded.

Long-term asset stewardship

Network ownership is a long-duration relationship. We approach every project accordingly — investing in the governance, systems, and processes needed to hold assets responsibly over their full operational life. Our clients choose Arcform because they want an owner who will still be doing this well in twenty years.

03

Network Operation

Reliable, safe, and compliant day-to-day operation of EHV electricity networks — so asset owners and connected parties can focus on what they do best.

Operations built around reliability

For high-demand industrial and commercial users, network reliability is not a nice-to-have — it is a commercial imperative. Downtime at a data centre, a manufacturing plant, or a generation asset can cost millions. The network operator bears direct responsibility for avoiding it.

Arcform's operational model is designed for the demands of EHV infrastructure. We bring together experienced engineers, rigorous safety processes, and modern monitoring capability to keep networks running — and to respond fast when they don't.

Operational services

24/7 network monitoring and emergency response for EHV assets
Planned and reactive maintenance across transformers, switchgear, protection systems, and civil infrastructure
Safety documentation, switching schedules, and network access management
Fault investigation, root cause analysis, and remediation
Capital investment planning and asset replacement programmes
Interface management with DNOs, National Grid, and contracted parties
Performance reporting and SLA management for connected customers

EHV-specialist operations. Most network operators deal primarily with low-voltage distribution. Arcform is focused exclusively on extra-high voltage — the technical standards, protection schemes, and regulatory requirements are different, and our operational team is built around that specialism.

Operational models

01

Fully managed operation

Arcform takes full operational responsibility for the network — monitoring, maintenance, emergency response, and regulatory compliance — under a long-term operations agreement.

02

Transitional operation

For networks moving between owners or undergoing significant change, we can provide interim operational management to maintain continuity and safety during the transition period.

03

Technical support services

Where clients have in-house operational resource, we can provide specialist EHV technical support, protection engineering, or emergency cover to complement existing capability.

04

Network Optimisation

Unlocking value from existing network assets through rigorous analysis, intelligent risk management, and targeted operational improvements.

The optimisation opportunity

Electricity networks are capital-intensive assets with long operational lives. Many were designed, built, or contracted under conditions that no longer reflect today's market — including changed load profiles, evolved regulatory frameworks, and new commercial structures in ancillary services and flexibility markets. The result is latent value that can be recovered with the right expertise.

Arcform's optimisation practice identifies and captures that value. We work with existing asset owners and operators to improve network performance, reduce costs, and position assets to benefit from evolving market opportunities.

What optimisation looks like in practice

Connection agreement review — identifying restrictive or commercially unfavourable terms and developing strategies to renegotiate
Demand and load profile analysis to identify flexibility and curtailment reduction opportunities
Ancillary service and flexibility market participation for connected assets
Protection and control system review to reduce unnecessary fault-driven disconnections
Maintenance regime benchmarking and cost reduction without compromising reliability
Power purchase and network charge optimisation for high-demand connected users
Technical loss reduction and power quality improvement

Risk management at the core. Optimisation without proper risk management is just cost-cutting. We build a complete picture of each asset's risk profile — technical, regulatory, and commercial — before recommending any changes. The goal is durable improvement, not short-term gains that create future problems.

Ongoing monitoring and reporting

For clients who retain us on an ongoing basis, we provide regular performance reporting against agreed benchmarks, early warning of emerging issues, and continuous identification of further improvement opportunities. Networks and markets evolve; our optimisation work evolves with them.

Who engages us for optimisation

Asset owners who suspect their network is underperforming. Infrastructure funds managing portfolios of energy assets. Developers who have built and now want to extract maximum long-term value. Industrial and commercial businesses with significant electricity costs who believe their network arrangements could be structured more favourably. If you have a large-scale electricity connection, there is almost certainly optimisation value to be found.
