Applications
Built for the most demanding energy applications
The energy transition is creating new classes of electricity infrastructure challenge — in storage, generation, and demand. Arcform's services are designed to address each one, with specialist EHV expertise that generalist consultants and contractors cannot match.
Energy Storage
Grid-scale battery and storage projects have unique network requirements. We provide connection strategy, ownership, and optimisation tailored to the storage asset class.
Read more 02Generation
Wind, solar, and conventional generation at scale demand complex EHV connections. We support developers from initial connection strategy through to energisation and ongoing network management.
Read more 03Demand
Data centres, EV infrastructure, and industrial facilities are driving a new wave of large-scale demand connections. We help high-demand users secure, structure, and optimise their grid connection.

Grid-scale battery energy storage systems are one of the most important and fastest-growing asset classes in the UK energy transition. They present a distinct and demanding set of network challenges — ones that Arcform is specifically equipped to address.

The storage connection challenge
Battery storage projects — particularly those over 50MW — require EHV connections that are fundamentally different in character from conventional generation or demand connections. They import and export power rapidly, often within seconds, and the connection must be designed to accommodate bidirectional power flows with precision. Grid code compliance for storage assets has evolved significantly in recent years and continues to change.
At the same time, the connection queue is long and competitive. Storage developers who do not understand the nuances of how to position their projects — technically and commercially — are at a significant disadvantage.
The challenge and our response
The challenge
Rapidly shifting power flows create demanding protection and control requirements that generic connection designs do not adequately address.
Our response
We design connection solutions specifically for storage profiles, with protection schemes tuned to the actual operating characteristics of the asset.
The challenge
Connection queue timelines are often misaligned with storage project development and financing milestones, creating investment uncertainty.
Our response
We provide realistic timeline assessments from the outset and manage the queue process actively to minimise delays and maximise predictability.
Co-location expertise. Increasingly, storage assets are co-located with generation — particularly solar — and the connection must serve both. We have experience structuring co-located connection arrangements that work technically and commercially for both asset types, including the complex metering and export management requirements these projects involve.
What we do for storage projects
Generation
Large-scale electricity generation — whether wind, solar, or other technologies — sits at the heart of the UK's energy transition. The network connections these assets require are among the most complex and consequential in the industry.

Generation at scale
The UK's clean energy targets require substantial additions of new generation capacity — primarily wind and solar, but also flexible generation that can provide system services. Each of these projects requires a bespoke, carefully structured connection to the transmission or distribution network. The connection is not a commodity: it is a critical part of the asset's value.
Developers who treat the connection as an afterthought — or who rely on generalist advisers without deep EHV expertise — often find themselves facing delays, cost overruns, and connection agreements that constrain the asset's operational performance for decades.
Our generation services
Protecting revenue at the connection. A poorly structured grid connection agreement can limit a generation asset's export capacity, impose unfair curtailment risk, or create commercial uncertainty that affects project financing. We review every connection offer with the asset's long-term revenue profile in mind — not just its technical compliance.
Technologies we support
Our generation connection expertise is technology-agnostic. We work with solar PV developers on distribution-connected subsidy-free projects, with onshore and offshore wind developers on transmission-connected assets, with developers of open-cycle and combined-cycle gas plant providing flexible capacity, and with emerging technologies including hydrogen-ready assets and advanced modular generation.
High Demand Users
The electrification of the economy — driven by AI infrastructure, EV charging, industrial decarbonisation, and digital growth — is creating a new class of high-demand electricity connection need. These are some of the most technically and commercially demanding connections in the system.

The new demand landscape
Demand for large-scale grid connections from non-generation users has grown dramatically. Data centres — particularly those supporting AI workloads — are seeking connections of 100MW, 200MW, and beyond. EV charging hubs for commercial and freight operators require significant dedicated infrastructure. Industrial facilities decarbonising their processes need new high-voltage connections where historically they may have relied on gas.
These demand-side projects create challenges that are materially different from those faced by generation developers. Network capacity, reliability, and commercial flexibility are paramount. The cost of connection — and the cost of getting it wrong — can be enormous.
What high-demand users need
Data centre expertise. We understand that a data centre's grid connection is not just a utility — it is a core component of operational resilience. We design and structure connections that reflect this: with the right level of redundancy, the right commercial protections, and the right technical standards for mission-critical load.
