Sectors
Deep expertise across
the energy landscape
Arcform operates across the three primary sectors of complex electricity network infrastructure in the UK — private networks, transmission, and IDNO. Each brings distinct regulatory, technical, and commercial requirements. Our IDNO focus is deliberately EHV: large-scale industrial and commercial networks, not low-voltage housing estates.
IDNO Projects
Arcform is pursuing its IDNO distribution licence from Ofgem with a deliberate focus: EHV-connected infrastructure for large-scale industrial and commercial customers. This is not a conventional IDNO play — it is an extension of our core specialism into the regulated ownership of complex, high-voltage networks serving demanding users.

A different kind of IDNO
Most IDNOs focus on adopting low-voltage networks serving new housing estates — a well-established model that Arcform has no interest in competing in. Our focus is different: the EHV distribution networks that connect large energy users, generation assets, and complex commercial sites to the public distribution system at 11kV and above.
These are the networks that sit at the boundary between private infrastructure and regulated distribution — technically demanding, commercially significant, and poorly served by operators without genuine EHV expertise. That is precisely where Arcform operates.
Licence in progress. Arcform is actively pursuing its IDNO distribution licence with Ofgem. We are engaging with prospective clients now to ensure we can move quickly once licensed. If you have a large-scale EHV network that needs a long-term regulated owner, we would welcome an early conversation.
What we are building towards
Once licensed, our IDNO capability will be specifically designed for complex, high-voltage assets:
Who we are looking to work with
Developers and owners of large-scale generation assets whose connection infrastructure sits at EHV distribution voltage. Industrial and commercial sites with significant on-site networks that could benefit from regulated ownership structures. Investors acquiring energy assets who need a specialist regulated operator for the network component. Projects where the boundary between private network and regulated distribution creates complexity that requires expert navigation.
Private Networks
Private wire and behind-the-meter networks are growing rapidly in importance as large energy users seek to reduce costs, improve resilience, and access renewable generation directly. Getting the design, ownership, and operation right is critical to realising those benefits.
Talk about private networks
The private network landscape
Private electricity networks — those not regulated as part of the public distribution system — serve an enormous range of purposes. They might carry power from an on-site generation asset to a collocated load. They might connect multiple buildings on a campus under common ownership. They might serve an industrial estate or logistics hub where energy costs are a significant operational factor.
What these networks have in common is that their performance directly affects the economic outcomes of the people who depend on them. A poorly designed or operated private network is not just an inconvenience — it is a cost, a risk, and a constraint on the business it serves.
What we offer
The EHV difference. Most private network operators work at lower voltages. Arcform's specialism is extra-high voltage — the 33kV, 66kV, and 132kV connections that serve the largest, most complex sites. This is where the technical challenges are greatest and where the consequences of getting things wrong are most significant.
Typical private network clients
Data centres with significant on-site power infrastructure. Industrial estates seeking shared energy services. University and hospital campuses with complex internal networks. Logistics hubs and distribution centres with high-demand connections. Developers of integrated energy communities combining generation, storage, and demand.
Transmission
Transmission-connected projects represent the highest end of the complexity spectrum in UK electricity infrastructure. They require deep technical knowledge, extensive regulatory experience, and a strong understanding of how National Grid and NESO frameworks operate in practice.
Discuss transmission
Transmission in the UK context
The GB transmission system — operated by National Grid Electricity System Operator (NESO) — operates at voltages of 132kV and above and carries electricity over long distances from major generation assets to the distribution network. Connecting to it, or building assets that interface with it, involves some of the most demanding technical and regulatory processes in the industry.
The scale of the UK's clean energy transition means that transmission connections are increasingly in demand — from large-scale offshore wind, solar farms, and battery storage to major interconnectors and industrial facilities. Queue times are long. Requirements are exacting. The need for expert guidance has never been greater.
Our transmission capabilities
Navigating queue reform. The NESO connections reform programme is fundamentally changing how projects secure transmission capacity. Projects that understand the new framework and position themselves correctly will gain significant advantage over those that do not. Arcform's team is working with clients through this transition in real time.
Scale and complexity
Transmission projects are, by definition, large. The assets are significant, the regulatory obligations are extensive, and the consequences of errors — technical or commercial — are material. Our team has the depth of experience to operate at this scale: we have been involved in major infrastructure origination, development, and financing across the energy sector for a combined period of decades.
