Networks Compliance

ESB Networks LCT Register Compliance

Acting as ESB Networks’ LCT Compliance Agency, getting the technologies of the energy transition assessed, registered and cleared to connect.

Heat pumps, EV chargers and inverter-connected generation must be registered with ESB Networks before they can be connected. Threepwood acts as the LCT Compliance Agency, taking manufacturers and installers through registration.

The challenge

Under ESB Networks requirements, low carbon technology devices — heat pumps, EV chargers and inverter-connected generation such as PV, wind and battery — must be registered on the LCT Register before they can be connected.

For manufacturers and installers the submission process and evidence requirements are not always clear, and a device that is not registered cannot be connected to the network.

As ESB Networks’ LCT Compliance Agency, Threepwood provides the route for devices to be assessed against the standards and registered.
Threepwood’s role in the LCT registration process

Our approach

Threepwood assesses device documentation against the relevant standards (EN 50549-1 and EN 50549-10), prepares the submission and manages it through to registration.

Registration typically takes up to four weeks, and templates and guidance are provided directly to manufacturers and installers so future submissions are quicker.

Illustrative growth in low carbon technology connections on the network: heat pumps, EV chargers and inverter-connected generation, each of which must be registered before it can connect.

The outcome

The results

01

A clear route to compliance

Devices are assessed and registered against the correct standards, removing uncertainty for manufacturers and installers.

02

Faster connections

A managed submission process helps registered devices reach the point of connection without avoidable delay.

03

Confidence for installers

Installers can specify registered devices knowing they meet ESB Networks’ requirements.

Internal Arc Integrity for Cable Transits

An internal arc fault turns a switchgear enclosure into a pressure vessel in milliseconds. Threepwood’s white paper assessed how a Roxtec cable transit system maintains that enclosure’s tested arc classification, giving operators an evidence base to specify it with confidence.

Overhead Line Enhanced Ratings

Static seasonal ratings treat every hour as the worst hour. Threepwood built the method and the tooling to rate overhead lines against the conditions they are actually experiencing, releasing capacity that is already there, safely within thermal and clearance limits.

HV Switchgear Enhanced Ratings

No published standard tells an operator how far high-voltage switchgear can safely be pushed above its normal rating, or for how long. Threepwood built the guidance and the calculator that provide the justification.
