An Independent Distribution Network Operator (IDNO) is a certified organisation with a broader role compared to an Independent Connection Provider (ICP). The ICP is responsible for constructing the electrical infrastructure and making the necessary connections. Once the IDNO takes over, it assumes ownership of the regional electricity network and is responsible for its ongoing maintenance, as well as handling fault repairs around the clock.
Yes – as a licensed IDNO, we are regulated by Ofgem, the UK’s energy regulator, to ensure we operate fairly, safely, and in your best interest.
You can reach us via our Contact Us page, where you’ll find phone numbers, email addresses, and an online enquiry form. We’re here to help Monday to Friday during business hours.
IDNOs commonly adopt:
• Residential, commercial, and industrial developments
• Battery storage facilities
• Data centres and large-scale industrial units
• Mixed-use developments
• EV Charging Hubs
Benefits include:
• Competitive asset value contributions
• Flexible design and construction standards
• Efficient project delivery timelines
• Nationwide operational capabilities
• Potential cost savings on network charges
IDNOs (Independent Distribution Network Operators) are licensed to own and operate electricity networks in the UK, typically serving new housing or commercial developments. At AEN, we operate as an IDNO, delivering power to local sites by connecting to a larger distribution or transmission network.
DNOs (Distribution Network Operators) manage the regional electricity infrastructure and cover much larger geographic areas.
Both IDNOs and DNOs are regulated by Ofgem (the Office of Gas and Electricity Markets). While DNOs oversee the main regional networks, IDNOs are responsible for maintaining the local networks they build and operate, including handling any faults or repairs.
A firm connection includes more than one path for delivering power. This means that if part of the network fails, there’s an alternative route to keep the supply running. It offers a higher level of reliability.
A non-firm connection has a single route for electricity to reach the site. If there’s a fault on the network, the supply is more likely to be interrupted and may take longer to restore. While this option is less resilient, it can be more cost-effective where constant supply isn’t critical.
A Statement of Works (SoW) is part of the process used to assess how a new generation project might affect the national transmission system. It’s sometimes called a transmission impact assessment.
If a project connects to the local distribution network but could still have an impact on the wider transmission system, it must go through this process before being approved for connection to the grid.
AEN adopts electricity networks across a wide range of developments, including:
Commercial sites
Industrial facilities
Residential housing schemes
EV charging infrastructure
Data centres
Battery storage installations
If your project requires a new network connection, we can support the adoption and ongoing operation of the infrastructure.
