1.0 Introduction and PurposeAll DNOs are required to comply with a common Competition in Connections Code of Practice (CoP). The requirements of the CoP is for each DNO to enter into arrangements that will enable ICPs to determine the Point of Connection (POC) in prescribed circumstances, Self-Approve Designs, Self-Inspect and carry out Self-Connection Operational activities.

This document is to set out arrangements that will allow an ICP to carry out all of the above functions to deliver a Small Service metered demand connection (up to 70kVA).

UK Power Networks have facilitated this by using a simple Excel spreadsheet which is called the Small Service Self-Service tool (CON 08 120a), and is explained later in this document.

2.0 ScopeThe scope described below is intended to help ICPs to successfully self determine the POC for single and three phase loads of up to 70kVA from a matrix, produce a construction plan using the templates provided within the tool, and be used in conjunction with Self-Connect activity for LV metered connections.

Benefits of the Small Service Self-Service (SSSS) process are:

The ICP using the SSSS tool does not need to have the NERS scope for Design The SSSS tool is set up in a way where ‘no technical’ input is needed. Simplifies and reduces the ‘touch points’ from UK Power Networks and aids the ICP to

fully ‘Self-Serve’. Aids the ICP to be able to compete in the small service connection market.

The SSSS tool can be used for, but not restricted to, the following scenarios:

Single or Three phase connections to a dwelling Multiple connections from one service joint to multiple dwellings (up to six connections

from one joint as long as the demand does not exceed 70kVA and longest service length doesn’t exceed 43m)

Single or Three phase connections for a TBS supply (no disturbing loads) Single or Three phase supplies for Electric Vehicle charging points

The process can only be used for pure ICP metered demand service connections. IDNO service connections, any associated G83 DG and disturbing loads are out of scope. However, the scope and process will be kept under review during implementation and may be subject to change as experience is gained.

2.1 Low Voltage Points of Connection up to 70kVAThese arrangements will apply for LV POCs and only if all the following conditions are met, as applicable:

The Requested capacity for the site/premise is no greater than 70kVA

The existing network is a three phase network (for three phase supplies)

The Point of Connection (POC) will be to an existing underground mains cable

The proposed network is an underground network

The minimum existing mains cable size at the Point of Connection (POC) is 120mm² Al or equivalent

The maximum length of LV main between substation and end of main does not exceed 300 metres (Not from substation to the new POC location)

The service cable length does not exceed 43m



The arrangements will not apply for the following circumstances:

Any connections within a ‘development area’ (i.e. where other new connections to same network are expected within next 12 month period)

Any connection for Distributed Generation (G83 single premises included)

Any connection where demand characteristics are likely to cause disruption to other customers (disturbing loads)

Any connection where reinforcement is required

3.0 ObjectiveTo allow an ICP to compete in the small service market by using the SSSS tool to determine the point of connection (POC), for projects at LV up to 70kVA, Self-Approve a Design, Self Inspect their contestable works and Self-Connect. The first two elements of this (Self-Determination of PoC and produce a construction plan using the templates provided within the tool) are captured in one excel document that will be explained in later in this procedure (SSSS tool).

6.0 ResponsibilitiesThe use of this procedure is conditional on ICP compliance with the requirements which should be read carefully. If the procedure is not followed correctly, there is a risk of incorrect network operation that could potentially lead to interruption of electricity supply for both existing and new customers.

The ICP accepts that this procedure may only be used for so long as it:

Has appropriate NERS accreditation for the task to be undertaken.1. Network Connections – Jointing, LV Mains & Services2. Network Connections – Operational, LV (not mandatory)3. Jointing – LV Dead & LV Live4. Cable Laying LV

Uses suitably experienced staff to carry out the interrogation of UKPN cable records

Accepts liability for the costs of any remedial works that become necessary as a result of failing to operate the procedure as documented

Accepts that UK Power Networks will provide information to the same level of accuracy as is provided to its own connections teams.

UK Power Networks reserves the right to withdraw use of this procedure from any ICP that does not comply with its terms.

Any information that UK Power Networks is to provide under this procedure will be to a comparable level of accuracy as is provided to its own connections teams.

7.0 RecordsUK Power Networks

To monitor performance of ICP’s using the SSSS tool, data will be captured and held by the Competition in Connections Commercial Analyst team. This data will be used to highlight any deficiencies in the process; regardless whether it is a UK Power Networks or an ICP deficiency. The data captured should also be able to provide sufficient evidence in respect to an ICP’s ability to use the SSSS tool and deliver the expected customer service to the end customer, by way of time it takes to populate the SSSS tool and deliver the connection.



The Competition in Connections Commercial Analyst team will be responsible for the control of a list detailing the performance of each ICP. This list will be regarded as ‘confidential information’ but may be disclosed to Lloyds NERS upon request.

For customer applications a project file will be created within UK Power Networks systems, all records created during the life of the project will be kept in this common file.

Independent Connection Provider

The ICP shall maintain a full and comprehensive record of information and drawings supplied to UK Power Networks, and these shall be made available at the earliest opportunity if they are required for inspection by UK Power Networks.

8.0 Process DetailGeneral Provisions

The ICP will be provided with access to network cable records via the RDS link to Netmap.

The ICP will not be permitted to access UK Power Networks substations, feeder pillars or link boxes without the appropriate UK Power Networks competency. This will not be required for using the SSSS tool.

The ICP proposals must comply with all UK Power Networks design and engineering standards.

Notification of Point of Connection

The ICP shall notify UK Power Networks with the following when undertaking a SSSS application:

Notification of intent to self-determine POC (Using the SSSS tool)

Submission of SSSS tool

Both of the above to be sent in one email.

At the initial stage of confirming the intent to self-determine a POC using the SSSS tool, the ICP shall complete the UK Power Networks application form titled ‘Application for Electricity Connection Request Form’ and send to [email protected]

To populate the form:

Populate Section A. Section B, tick box F (Intending to Self-Determine a Point of Connection – No Quotation

required) On Page 3 tick box D Section G (Additional Info) state in BOLD TYPE, that you INTEND TO USE THE SMALL

SERVICE SELF-SERVICE TOOL FOR THIS PROJECT. (please state EV, before the word PROJECT, if the connection is for an Electric Vehicle Charging Point)

Once the Application Form (and SSSS tool explained on the next page) has been received by UK Power Networks a project reference number will be generated and an acknowledgement email sent to the ICP. The ICP will communicate any further progress or changes via email to UK Power Networks via the [email protected] mailbox.

When using the SSSS tool, the ICP will navigate through the tabs on the excel spreadsheet.


mailto:[email protected]



Tab 1: Tick Sheet

A tick sheet to check if the small service project falls into scope (example of tab one below).

Tab 2: Relevant Documents

A reference page with links to our G81.



Tab 3: EXAMPLE POC Location

An example for the ICP to refer to when populating the SSSS tool for their site location. The ICP shall annotate a UK Power Networks’ 1-500 cable record to identity the proposed POC and site boundary. It must be clear what cable has been selected for the POC from the LV schematic.



Tab 4: EXAMPLE Design

An example for the ICP to refer to when populating the SSSS tool for the design. The ICP shall populate the Plan View box with a snap shot of the area, from Google Maps or an architectural drawing, which will be used for the final connection arrangement. This must show the existing LV main and proposed service cable route to the indicative cut out location. This can be drawn on excel using the ‘insert shapes’ function.

If the proposal is for multiple services from one service joint (not exceeding 70kVA), the service cable routes need to be clearly shown.

The meter housing box will be populated by cutting and pasting from the Meter Housing tab 9. The Sections on the public highway box can be populated using the relevant sections (cable installed in footpath or carriageway) from the Sections Tab 8.



Tab 5: INFO

The Point of Connection Criteria will be populated by inputting all the relevant information in the ‘Info’ tab. This will only need to be inputted once as the information will be duplicated into the ICP POC Location and ICP POC Design tabs.

When populating the Proposed underground low Voltage main size (from the drop down list), if the cable chosen is smaller than 120Al or equivalent then the cell will turn red to highlight that the POC will need network modelling.

When populating the Size of feeding transformer (from the drop down list), if the transformer chosen is smaller than 300kVA then the cell will turn red to highlight that the POC will need network modelling.

When populating the LV distributed circuit length, if the figure is greater than 300m then the cell will turn red to highlight that the POC will need network modelling.



Tab 6 and 7: ICP POC Location and ICP Design

These two tabs are the tabs to be populated for the small service project the ICP is intending to use the SSSS tool for. Tab 6 and 7 are blank versions of tabs 3 and 4. Under the Material List column the ICP will use the drop boxes to choose the equipment they are proposing to install. By clicking on the item (cut out, Service Cable etc.), this will cause a dropdown arrow to appear on the right hand side of the box for the ICP to choose the correct equipment.

The ‘Earthing System’ box will be populated by UK Power Networks to inform the ICP which type of earthing system is expected to be installed.

Tab 8: Sections

This tab is where the ICP will copy the relevant sections applicable to the service cable install and paste them into the ‘Sections’ on public highway box in tab 7.

Tab 9: Meter housing

This tab is where the ICP will copy the relevant meter housing arrangement applicable to the service cable install connection position and paste them into the ‘Meter housing’ box in tab 7.



Inspection of SSSS tool

UKPN will inspect every SSSS submission, and where the SSSS inspection process highlights that the SSSS tool has been completed incorrectly or an element of the matrix is out of scope (i.e. Cable smaller than 120Al, TX smaller than 300kVA or LV main length greater than 300m), UK Power Networks shall make the corrections or carry out LV network assessment. UK Power Networks shall confirm back to the ICP, once the POC passes a network assessment, that the proposed POC is now acceptable. UK Power Networks will also state on the ICP Design tab of the SSSS tool the type of earthing system UK Power Networks would expect to be installed with the type of connection, i.e. for a TBS/EV charging point a TT earthing system should be installed.

If the proposed POC fails a network assessment, and will need network extension, reinforcement or cable overlay, the ICP shall be informed of this and the ICP will need to send an application for a LC15 non-contestable offer to the following email address: [email protected]

It however should be noted that any inspection completed by UK Power Networks shall be regarded as an integrity check only, i.e. the POC design is suitable to facilitate the electricity connection. Checks such as minimum cost scheme will not be inspected.

Regulation

The ICP must be certified under the Lloyds Register NERS scheme as accredited to carry out the specified work on UK Power Networks distribution system. This will include one or many of the following Lloyds NERS scopes, or as modified by Lloyds NERS:
