4 3. Operational and Safety Matters 3.1. Contacts A list of contacts, addresses and telephone numbers for Northern Powergrid s distribution systems are given in Appendix Distribution Safety It is the responsibility of the Meter Operators to ensure that all work on or in the vicinity of electrical equipment undertaken by the Meter Operator is carried out in a safe and competent manner to a level complying with or exceeding the requirements of health & safety and electricity related legislation and, in particular, relevant requirements of the Electricity Act 1989 (as amended), the Utilities Act 2000, Electricity At Work Regulations 1989 (as amended) and the Electricity Safety, Quality and Continuity of Supply Regulations It is the responsibility of the Meter Operator to take note of distribution business information provided by Northern Powergrid and to circulate all relevant aspects to their operatives including, not exhaustively, such aspects as Northern Powergrid s emergency contact phone numbers, equipment risk assessments and notices of equipment defects and notifications of unsafe areas where special access arrangements through Northern Powergrid may apply Contact details for advisory support, in relation to distribution asset related matters only, are listed in Appendix Northern Powergrid s responsibilities as asset owner, having no contractual client relationship with Meter Operators who have separate licensed rights of access in fulfilling electricity supplier activities, are broadly limited to the provision of appropriate safety information relating to distribution equipment in relation to electrical, physical or other risks of which Meter Operators should be aware so as to ensure the safety of their operatives. As such, Northern Powergrid will: Provide emergency contact information for reporting of dangerous occurrences and for reporting of defective distribution equipment. Provide safety information, defect information and risk assessment information so far as deemed relevant and appropriate to the service termination assets upon which Meter Operators are entitled to work. Relevant Defect Information and Risk Assessment information is contained in Appendices 2 and 3 of this document. Reserve the right to audit Meter Operator organisations, including management, safety officers, competency appointing officers and meter operatives As asset owner and distribution meter point administrator, Northern Powergrid will also: Provide contact information for essential site commissioning information. Provide contact information for return of Northern Powergrid s meters from Northern Powergrid s distribution systems. Page 4 of 21

5 3.3. Competent Persons UK Legislation requires that all persons put to work on electrical equipment must be Competent Persons. The nationally accepted definition related to work control is that: No person shall be engaged in any work activity where technical knowledge or experience or supervision is necessary to prevent a danger or where appropriate, injury, unless he possesses such knowledge or experience or is under such supervision as may be appropriate having regard to the nature of the work The Meter Operator has a duty to its employees of ensuring their competence for particular tasks they may be instructed to undertake As the employing organisation it is the responsibility of the Meter Operator to assess competence of their employees and sub-contractors, including initial and refresher assessments and any other form of validation and supervision that the Meter Operator deems necessary to ensure compliance with legislative requirements Northern Powergrid has no client responsibility for un-contracted Meter Operator organisations, no responsibility towards training of meter operatives but Northern Powergrid will retain the right for assessing competence of meter operatives associated with providing a valid authorisation certificate appropriate to the requirements of each operative The Meter Operator s prime client contractual relationship is with the contractually appointing electricity supplier. It is through the existence of a contract with an electricity supplier that a Meter Operator may undertake activities on Northern Powergrid s distribution network. The responsibility for assuring competence of meter operatives and subcontractors resides fully with the relevant Meter Operator and with their contracting electricity supplier client Subcontracted Meter Operators shall require the same level of authorisation as the principle meter operator but the subcontractors authorisation will be restricted to work only for the principle meter operator Northern Powergrid does, however, fully reserve distribution network operator rights to suspend or prohibit any activities of registered Meter Operators and any other parties with legitimate rights/licence to work upon Northern Powergrid s distribution system equipment and to eject such persons from site in such cases that dangerous activities, unacceptable condition of completed works or evidence of serious deficiency in competence are observed, assessed or reported by, or to, Northern Powergrid. The implicated party(parties) will not be allowed to complete any further work on Northern Powergrid s distribution systems unless exonerated by a formal inquiry undertaken jointly by Northern Powergrid and the Meter Operator and / or following satisfactory further training / retraining and assessment to the satisfaction of Northern Powergrid Meter Operator Authorisation & Assessment Process Northern Powergrid Distribution Safety Rules define a competent or authorised person. In general these are individuals with adequate training, experience and knowledge who has been assessed and authorised in writing to undertake specific tasks on electrical plant or equipment Northern Powergrid expect the Meter Operator to provide evidence on skills assessment / accreditation prior to issuing any authority code certificate and reserve the right to require individuals to undertake a trade test to audit the skills and accreditation of Meter Operator staff Where a Meter Operator nominates an individual for system authority codes the nomination form detailed in appendix 8 will be used. The Meter Operator should provide Page 5 of 21

6 sufficient evidence to support the nomination for the appropriate Northern Powergrid system authority code(s) as detailed in appendix 7 (or reference the web site) The Northern Powergrid Authorising assessor shall be provided with the candidate s assessment request, which must include the signed recommendation for authorisation from the Meter Operator s own Authorising assessor The Northern Powergrid Authorising Officer will satisfy himself that the candidate has the necessary skills and ability to work safely on or near the relevant distribution networks and that the candidate understands the limitation of the authorisation being given prior to issuing an authorisation certificate Northern Powergrid will define the limit of the authorisation and validation period which will be a maximum of 3 years. The Meter Operator is required to undertake an annual review of each individual s system authority codes to ensure that the duties and activities performed within the review period are commensurate with the assigned authorisation/competence The Meter Operator shall carry out regular audits on its operatives to ensure they are compliant with the requirements of their Northern Powergrid authorisation. The audit finding shall be made available to Northern Powergrid to review if requested In the event that the authorised person has not performed the responsibilities for which he has gained the authorisation within the review period, Northern Powergrid will withdraw authorisation until additional test/assessment is undertaken in order to reinstate the authorisation level Access to Northern Powergrid s Distribution Substations Unsupervised access to Northern Powergrid s Distribution Substations by parties not undertaking contracted works on behalf of Northern Powergrid will not be granted under any circumstances Distribution keys shall not be issued to any party other than for the purposes of allowing a party to conduct distribution network activity being undertaken under contract to Northern Powergrid Where access is required by the Meter Operator requests for supervised access should be made to Northern Powergrid. The points of contact and telephone numbers are given in Appendix Where service termination and metering equipment are housed in customer buildings access should be made by arrangement with the customer, as controller of the premises, and with supervision provided by the customer as appropriate according to the nature of their property and their installation. In such cases Northern Powergrid will generally not provide supervised access Reporting of Defects, Incidents and Dangerous Occurrences Any equipment owned by Northern Powergrid found to be defective, such as to present the possibility of danger or any part of the site or situations which are, or which might reasonably be, believed may become hazardous should be reported immediately by the Meter Operative. The points of contact and telephone numbers are given in Appendix A list of known defects on service termination equipment for which the Meter Operator should make their operatives aware is provided in Appendix 2. Are we sure Appendix 2 covers this sufficiently (metal clad cutouts / asbestos etc) In addition, it is also a requirement under relevant safety legislation to report accidents and dangerous occurrences to the relevant reporting authority and such accidents and dangerous occurrences that relate to Northern Powergrid distribution Page 6 of 21

7 systems must also be reported to Northern Powergrid at the earliest possible opportunity. The points of contact and telephone numbers are given in Appendix Removal and Replacement of Cut-out Fuses Where the work to be done on behalf of the appointed electricity supplier, by their registered meter operator, requires the removal and subsequent replacement of the main supply fuses then this may take place without reference to Northern Powergrid provided the meter operator is suitably authorised to carry out the task, other than the requirement for any incident or accident to be reported immediately in accordance with Paragraph 3.5 above and for the Meter Operator to reseal all distribution service termination equipment in accordance with the Meter Operators Code of Practice and relevant codes of practice Persons removing or replacing main supply fuses must: Be assessed and certified as competent by the Meter Operator Be appointed in writing to carry out this activity at the property concerned on behalf of the Meter Operator on behalf of their appointing supplier. Be authorised by Northern Powergrid to carry out the task Be in receipt of formal work instructions from, or arising from, instructions from the property s appointed electricity supplier to undertake activity that necessitates the operation of the main supply fuse Operation of Northern Powergrid s Service Termination Switchgear/Isolators Whilst the majority of Northern Powergrid s service terminations are cut-out fused, there are other types of service termination at low voltage, high voltage and extra-high voltage that have switchgear or isolators as the exit point s means of energisation and deenergisation of the main current carrying electrical circuit to the customer s installation Where the meter operator is instructed to conduct works that require the deenergisation or re-energisation of a Northern Powergrid service termination, whose isolation device for the main current carrying electrical circuit is a distributor locked switchgear or isolator, the meter operator should refer the request back to their supplier and not proceed with their works. The appointed electricity supplier must arrange for Northern Powergrid to effect the de-energisation or energisation of service terminations with these types of isolation equipment Testing of customer electrical installations prior to connection or energisation Where the work to be done by the Meter Operator, on behalf of the appointed electricity supplier, involves the connection, energisation, or re-energisation of customer s electrical installations the safety of the installation must be assured prior to such connection, energisation, or re-energisation as detailed in F, I, K, L & M of the MOCOPA rules (see Appendix 2) Under regulation 25 of the Electricity Safety, Quality and Continuity Regulations 2002 (ESQC Regulations), Northern Powergrid does not give consent to make or alter connections of customer installations where we have reasonable grounds that the customer s installation does not comply with the British Standard Requirements 1 and the ESQC Regulations themselves Accordingly, Northern Powergrid requires that all Appointed Electricity Suppliers and all appointed Meter Operators ensure, given the nature of installation being connected, energised or re-energised, that the installation is safe to connect and complies with the British Standard Requirements and the ESQC Regulations. Page 7 of 21

8 N.B. British Standard Requirements means the British Standard Requirements for Electrical Installations BS 7671 : [2008 IEE Wiring Regulations 17th Edition (ISBN )] as incorporated in the Electricity Safety, Quality and Continuity Regulations 2002 by the Electricity Safety, Quality and Continuity (Amendment) Regulations 2009 (SI 2009/639); Northern Powergrid - MOCOPA Distribution Business Information.doc Where the Meter Operator is fitting an isolating switch and customer accessible PME terminal block on the installation side of the metering system, to enable a third party to later connect wires into the fitted isolator and customer accessible PME terminal block, these items form part of the electrical installation Accordingly, Northern Powergrid requires that the Meter Operator shall conduct such tests as are necessary and sufficient to ensure that the fitted isolator switch and customer accessible PME terminal block is safe to connect and complies with the British Standard Requirements and the ESQC Regulations. The Meter Operator shall retain records of such tests and results For the avoidance of doubt, where customers installations at the time of requested connection comprise a very limited extent of electrical lines and plant that has been demonstrated through tests and certificates to comply with British Standard Requirements, then connection of the electrical installation should be made. For example, where a customer s initial installation comprises a double pole isolator with meter tails ready for connection to a metering system and a customer earth block with conductor ready for connection to a PME terminal and the customer s installation complies with British Standard Requirements then connection should not be refused Following the Meter Operator s connection of a customer s electrical installation demonstrated to be compliant with the ESQC Regulations the liability for subsequent modifications to the customer s installation resides fully with the customer. It is the customer s responsibility to liaise with their appointed electricity supplier and electricity distribution company if they plan to make changes to their electrical installation which are likely to affect, or exceed, the customer s previously agreed requirements of the distribution system or metering equipment. They must liaise with the relevant parties before any such material changes to their electrical installation are made. Page 8 of 21

9 4. Technical 4.1. Meter Operator Equipment Attachment The Meter Operator s meters and associated equipment must not obstruct or restrict access to Northern Powergrid s distribution equipment, or be attached to it without the prior written agreement of Northern Powergrid The Meter Operator s meters must not be fixed upon Northern Powergrid s equipment or property, such as metering panels, without the prior written agreement of Northern Powergrid For the avoidance of doubt meter boards are the property of the occupier and, unless ownership is declared by Northern Powergrid, no permission would be required from Northern Powergrid for the appointed Meter Operator to fit meters upon the meter board. The occupier provides meter boards with the intent to house both distribution and metering assets and consent is implicitly given for the fitting of such assets as a precondition of enabling a supply of electricity to be provided. Modern meter cabinets are provided by the customer for the fixing of the cut out termination and metering. Historically, Northern Powergrid may have installed meter boards at internal metering positions on behalf of the customer as part of the connection arrangement It is the responsibility of individual Meter Operators and/or their contractors, to satisfy themselves as to the wiring arrangements at any particular location, to ascertain the nature of the connections at the site and act accordingly. Northern Powergrid does not accept any liability whatsoever for independent Meter Operators actions on site and the Meter Operator and / or their contractors must bear entire responsibility in all respects Service Termination Access Meter Operator Obligations The Meter Operator shall not allow, nor do anything so as to allow, any third party access to the distributor s equipment, including, not exhaustively service fuse cut-outs, service isolator switches, multi-way service distribution panels and any associated distribution service termination equipment and conductors Where the Meter Operator is fitting an isolating switch on the installation side of the metering system, whereby a third party may connect wires into the fitted isolator, the Meter Operator shall ensure that all appropriate arrangements are made, including fitting a customer accessible PME terminal block to the distributor s neutral terminal, such that the third party can perform all his work without touching the distributor s equipment. The Meter Operator will have responsibility for any such occurrence unless the supplier has otherwise accepted it. Where the Meter Operator fits customer accessible isolating switches, or customer accessible PME terminal blocks, he shall leave a clear safety notice or label with the equipment describing the state in which it has been left Communications Links Any equipment which is required to be installed by the Meter Operator for communications must be installed in a proper manner and not obstruct or restrict access to Northern Powergrid s equipment or the customer s installation Under no circumstances shall Northern Powergrid s equipment or communications links, if present, be disconnected without permission. Any resultant costs incurred by Northern Powergrid from such unauthorised disconnections will be charged to the party responsible for the disconnection Under no circumstances shall Northern Powergrid s communication links be utilised by a Meter Operator without prior written agreement of Northern Powergrid. Page 9 of 21

10 In all circumstances, where an existing communication link is not owned by Northern Powergrid, the Meter Operator should gain prior written agreement from the owner if utilisation of that communications link is desired Where a radio/wireless communication system needs to be fitted to a substation, the position is to be agreed with the owner of the substation prior to installation. The fitting of radio/wireless communication systems and associated cabling must be carried out with care to ensure that it does not impair the building structure or weatherproofing or proper functioning of existing distribution equipment or metering equipment in any way whatsoever.

11 5. Commercial 5.1. Removed Meters Any of Northern Powergrid s meters or other equipment removed from site shall be either reused at another premise or else returned to us within 30 days of its removal. Removed meters/equipment shall be transported in a way that avoids interference or damage and can be returned to the address given in Appendix 1. Meter Operators should contact Northern Powergrid by telephone before making arrangements to return any meters/equipment. The meters/equipment should be clearly marked with the name and address of the site from which they were removed Returned meters should be accompanied by a listing of the serial numbers so returned, preferably in electronic format (MS Excel) Provision of Information The Meter Operator shall send all relevant data flows in accordance with the MRA and with the balance and settlement code (BSC) diagrams within 10 working days Wherever one of Northern Powergrid s meters is installed or removed, or if the Supplier or Meter Operator at a premises containing one of Northern Powergrid s meters changes, the Meter Operator shall inform Northern Powergrid (as MAP) using the relevant Data Flows, including the D0303. Wherever the Meter Operator fits a meter at a premises, the Meter Operator shall send the relevant Data Flows to Northern Powergrid (as distributor), including the D Charges Where a Meter Operator requests the attendance of Northern Powergrid staff to provide technical support any chargeable element will be notified in advance of work being undertaken Site-Specific Information Site-specific information will be provided only where the request for information is received by Data Flow D The information will be provided using Data Flow D Essential Commissioning Information and Certificate of Completion This information should be sent to the address given in Appendix 1 within 5 working days after Page 11 of 21

13 Appendix 2 MOCOPA Version 2.9 new metering point rules. In the case of new Metering Points, the following principles shall be adopted: (A) the Distribution Business and the MOCOPA Operator shall liaise with each other to ensure that new metering work and Energisation is completed with the minimum delay; (B) the Distribution Business shall agree with the customer or developer the position and space for the metering, and ensure it remains reserved. The location must be accessible to the customer so he can read his meter, and the MOCOPA Operator (via the customer or his agent); (C) for HV and LV CT metered supplies, the interface test/isolating facilities shall be installed in an accessible position near to the location of the proposed Metering Equipment. A label must be fitted in accordance with MOCOPA Appendix 2 - A2.3. (D) for whole current supplies, a means of isolating voltage supplies (e.g. cut-out) shall be installed in an area to which the MOCOPA Operator has access (via the customer or his agent); (E) for cut-out controlled supplies, the Distribution Business is responsible for providing the fuse carriers and fuses. Where these cannot be left on site (e.g. risk of unlawful energisation), the Distribution Business shall be responsible for providing them to the MOCOPA Operator in a timely and acceptable manner, if the MOCOPA Operator is to perform the energisation. (F) it is the responsibility of the Distribution Business to determine the rating of the cut-out fuses. The Meter Operative shall check the tails being provided by the customer are suitably rated for the cut-out fuses provided before he connects them, or energises the supply (this is limited to checking at the point of connection without needing to take into account any de-rating for thermal conditions within the installation); (G) the Distribution Business is responsible for commissioning the service (e.g. checking voltage, earth loop impedance, phase rotation, polarity and any protection settings, etc at the cutout/switchgear); (H) the MOCOPA Operator shall confirm the voltage, phase rotation and polarity at the supply terminals (metering output terminals or isolator switch terminals); (I) for whole current supplies, the MOCOPA Operator is expected to connect the customer s tails to the metering, or install and connect an isolator switch as agreed with the supplier, Distribution Business or customer; (J) where the Distribution Business is to provide an earth terminal for the customer, the Distribution Business shall ensure the terminal is accessible to the customer or contractor, or take responsibility for making the earth connection. (Note: The customer should have ongoing access to the earth terminal in order to carry out routine tests of his installation); (K) for HV and bulk LV CT-metered supplies, the Distribution Business is responsible for connecting the customer s tails, whether directly, by using an agent or allowing the customer s contractor access to suitable terminals; (L) for whole current supplies and cut-out controlled LV CT metered supplies, the MOCOPA Operator can normally be expected to energise the supply (taking into account any published Distribution Business-specific requirements and required Authorisations); Page 13 of 21

14 (M) for circuit breaker-controlled bulk LV and HV metered supplies, the Distribution Business is normally expected to energise the supply, in response to a request from the supplier; (N) the Distribution Business will not normally agree to Energise a supply until it is appropriately metered; (O) the MOCOPA Operator shall not carry out Energisation work unless and until authorised under MOCOPA Schedule 7 of the relevant Use of System Agreement; and (P) Conductors shall be coloured and marked in accordance with MOCOPA Appendix 11. Items (B) and (C) above shall be provided by the Distribution Business, chargeable to the Customer, and shall be capable of being sealed to prevent unauthorised access. MOCOPA Operators should take note of any requirements in the Distribution Business s Consent to Connect Statement. NOTE: Due regard shall be paid in siting meters to the requirements for overall Metering Equipment accuracy. These are affected by the burden imposed, which is related to the length of connections between current transformers and meters. Operational liaison between the MOCOPA Operator and the Distribution Business during commissioning of new Metering Equipment will be covered by the Distribution Safety Rules. Page 14 of 21

19 Appendix 7 Authorisation The supplier is responsible for making sure that their meter operators are suitably authorised to work on our system. Each individual meter operative MUST be authorised by Northern Powergrid to work on the Northern Powergrid distribution network BEFORE carrying out any metering work within the Northern Powergrid distribution services areas. The authorisation provided by Northern Powergrid enables the meter operative to remove and insert the main distribution service fuse in the cut-out ensuring that the meter is safe to work on. Individual meter operatives are nominated for authorisation by the MOCOPA Operator for whom they work. All approaches for authorisation MUST be via a MOCOPA operator; requests from individual meter operatives who are not working on behalf of a MOCOPA Operator will be declined by Northern Powergrid. Meter operatives can be trained by the MOCOPA Operator or may, on request, be trained by Northern Powergrid. Authorisation by Northern Powergrid takes the form of a technical assessment of the meter operative and an interview. If successful, the meter operative is issued with a certificate of authorisation and a copy of the Northern Powergrid distribution safety rules. Authorisations last for three years after which re-authorisation must be sought. CODE OPERATION ON LV SERVICE EQUIPMENT Single phase installations O1.2 O1.3 O1.4 O1.5 This covers all installations on domestic and commercial single phase installations on cut outs rated up to 100A. The code may be issued with a limitation excluding operations on rewireable and metal clad cut outs. Single phase of a multiphase supply This covers the removal of one fuse from a 3/2 phase cut out or one fuse from a multi way distribution board. Intended mainly for meter operators whose only requirement is to replace a single phase meter Multi phase installations This covers operations on all commercial and industrial installations, up to and including 500Amp cut-outs excluding ISU?s. Operation of main switches or LV CB?s is covered unless these are supplied directly from a S/S LV Board, in which case the LV mains operations code is required. Candidates issued with this code will normally receive code O1.2. The code may be issued with a limitation excluding operations on rewireable and metal clad cut outs. ISU installations with exposed LV This covers operations on industrial service units and multi way fuse boards. Candidates issued with this code will normally receive O1.2, 1.3 and O1.4 some ISUs are locked with a C /AX lock and the holder may also require code A1.1. Page 19 of 21
