What is an ICP?

Read more

In the electricity industry, ICP stands for Independent Connection Provider.

  • An ICP is an accredited company that can design and build new electricity connections outside the traditional Distribution Network Operators (DNOs)
  • They operate in competitive parts of the utilities market, giving customers more choice when securing new connections
Dunamis is a leading ICP specialising in the design and build of High Voltage (HV) grid connections and networks.
  • One of only a few ICPs in the UK on the LRQA NERS register, able to deliver projects up to 132kV
  • Successfully energised over 200 projects across the UK

What do ICPs (Independent Connection Providers) do?

Read more

ICPs manage the entire journey of a new electricity connection—from design to adoption.

  • Design the network: Fully coordinated from day one to deliver best value
  • Build the infrastructure: Joined-up installation to avoid clashes and minimise delays
  • Manage adoption: Handle the process of transferring the network to a utility owner, whether a regional incumbent or an Independent Network Owner

In brief: We design it. We build it. We connect it. We manage adoption.

Dunamis is one of only a few ICPs on the LRQA NERS register, capable of delivering HV projects up to 132kV, with over 200 successful energisations across the UK.

What is a High Voltage (HV) connection?

Read more

A High Voltage (HV) connection supplies electricity at higher voltages—typically 11kV, 33kV, 66kv or 132kV—for large-scale developments, commercial sites, or industrial facilities.

HV connections are needed when standard low-voltage supplies (400V / 230V) cannot provide enough power.

Why a site might need an HV connection:

  • To supply large amounts of electricity reliably
  • To reduce energy losses compared with multiple low-voltage connections
  • To future-proof developments for growth or higher electricity demand
Dunamis specialises in HV grid connections up to 132kV and has successfully delivered 200+ projects across the UK.

What is a POC?

Read more

A Point Of Connection (POC) is the specific location where a development or property connects to an existing utility network, such as electricity, water, or gas.

  • The POC is where your services join the wider network—e.g., a new cable connecting to the electricity grid, or pipework linking to a water main.
  • It is a critical part of design and approvals, as it determines how the site will access essential services and what works are required.

Establishing a POC ensures:

  • Safe and compliant integration with existing networks
  • Clear ownership and maintenance responsibilities
  • Accurate design and construction planning
  • Efficient coordination between developers and utility providers
Dunamis can help determine and secure the optimal POC for your project.

What is value engineering?

Read more

Value engineering is designing an electricity network with cost and time efficiencies in mind, while still meeting safety and regulatory requirements.

It focuses on smarter, more flexible solutions to deliver projects efficiently, without compromising quality or compliance.

Why it matters:

  • Delivers projects on time and within budget
  • Identifies efficient solutions for materials, layout, or construction
  • Provides flexibility compared to standard DNO requirements
  • Ensures full compliance with regulations and safety standards

Typical activities:

  • Optimising cable routes and substation layouts
  • Selecting cost-effective equipment or materials
  • Streamlining construction or installation methods
  • Reviewing designs to reduce unnecessary complexity

Benefits:

  • Saves time and money without compromising safety
  • Supports innovative, flexible project delivery
  • Ensures a high-quality, compliant network
Dunamis uses value engineering to deliver efficient, flexible, and compliant HV projects.

What do 11kV, 33kV, 66kv and 132kV mean?

Read more

These numbers represent standard voltage levels in the UK electricity network:

  • 132kV – High-Voltage Distribution
    • Transfers bulk power across regions
    • Connects Grid Supply Points (GSPs) to primary substations
    • Typically via overhead lines or major underground cables
  • 66kV – Sub-Transmission Distribution
    • Transfers power from Grid Supply Points (GSPs) to primary substations where 132kV is not used
    • Common in regional, rural, and legacy networks, via overhead lines or underground cables
  • 33kV – Intermediate Distribution
    • Moves electricity from primary to secondary substations
    • Common in urban, rural, and industrial networks
  • 11kV – Local Primary Distribution
    • Supplies local substations, stepping down to 400V / 230V for homes and small businesses
    • Can supply larger commercial and industrial sites directly

Why multiple voltage levels?

  • Reduces energy losses over distance
  • Ensures safe supply for end users
  • Enables smooth integration between generation, substations, and local networks
Dunamis delivers HV connections and infrastructure up to 132kV, with over 200 successful projects.

What is meant by future-proofed electrical infrastructure?

Read more

Future-proofed electrical infrastructure is designed to meet both current and future needs.

  • Handles growing energy demand and integration of new low carbon technologies (like EVs, battery storage, or renewables) without costly upgrades.

Why it matters:

  • Supports long-term growth in electricity demand
  • Accommodates new low carbon technologies and developments
  • Reduces future upgrade costs
  • It supports developers to decarbonise and achieve net zero
Dunamis helps ensure your electrical infrastructure is future-proofed, flexible, and reliable.

What is commissioning in new electricity infrastructure?

Read more

Commissioning is the process of testing, inspecting, and verifying new electrical systems before full operation.

  • Ensures all equipment, connections, and safety systems work correctly and meet standards

Typical activities:

  • Testing cables, transformers, and switchgear
  • Verification of protection systems and safety devices
  • Functional testing of control and monitoring equipment
  • Coordination with the Distribution Network Operator (DNO) before energising
Dunamis provides complete commissioning services as part of HV connections.
Contact us to find out how.

What is NERS accreditation?

Read more

NERS accreditation (National Electricity Registration Scheme) is a formal certification for contractors and companies working on HV and LV electricity networks in the UK.

  • Confirms that a company or individual has the skills, experience, and safety standards to work safely and professionally.

Why it matters:

  • Confirms a contractor is qualified and competent to work on live networks
  • Ensures compliance with regulations and safety standards
Dunamis is one of only a few ICPs on the LRQA NERS register, capable of delivering HV projects up to 132kV, with a strong track record of successful project delivery.

What is Contestable works and what is Non-Contestable works in electricity infrastructure?

Read more

In utilities, “contestable” refers to work that can be done by an Independent Connection Provider (ICP), while “non-contestable” work is restricted to the regional, large network operator.

  • Contestable works Include the more practical aspects of a new connection, such as installing cables and substations, and can be carried out by Independent Connection Providers (ICPs)
  • Non-Contestable works Include elements, such as the final connection to the existing network in the electricity sector, which must be performed by the network owner
As an Independent Connection Provider (ICP), Dunamis can package and coordinate both Contestable and non-contestable elements. So even if the work is “Non-Contestable”, we can help.
