Respondent Response National Grid The data National Grid Distribution (NGD) holds within their internal systems is received from Distribution the central Supply Point Register held by Xoserve. In addition to this, NGD holds further address information which has been derived from AddressBase and this complements the data we receive from the central Supply Point Register. Address data is used to carry out a multitude of business processes including but not restricted to emergency response, new connections, mains replacement, theft of gas and network planning. The data held within NGD systems is not used directly to assist in the customer switching process although any address errors which are found during our activities can be fed back to Xoserve via the address update process ensuring that such address amendments are reflected in the central Supply Point Register. SmartestEnergy Our systems hold a site address for pricing, a site address for billing and a customer/correspondence address for billing. We also have the MPRS address in our systems for registration purposes. Northern As a distribution business we hold the Meter Point Administration Number (MPAN) Address in Powergrid the Meter Point Administration System (MPAS). Updates to address information can be transferred over the Data Transfer Network (DTN) via formal data flows and in the agreed format as set out in the data transfer catalogue. Once captured within the Meter Point Administration Service (MPAS) system it then gets transferred to the Electricity Central Online Enquiry Services (ECOES) which is available to view by market participants. Our address data may be utilised by suppliers as part of the change of supplier process, potentially to select the Meter Point Administration Number (MPAN) or validate the address/MPAN provided by the customer. Failure to identify the correct MPAN or identification of an incorrect MPAN could result in delays to the customer switching process or erroneous transfers. Our address data (circa4.0m records) has undergone an initial data cleanse to validate our data in line with Postal Address Format data (using the Ordnance Survey product Address_Base_Premium). In addition, and where possible, we have applied the UPRN to our records. We are currently in the process of implementing a system to maintain our address data in this way on an enduring basis. In terms of supplier address amendment requests, to ensure we maintain the quality of our ADWG/02 v0.4 Page 3 of 144 22 September 2015 ADDRESS DATA QUALITY CONSULTATION RESPONSES address data each request is validated in line with Royal Mail and our existing MPAN data prior to accepting or rejecting the request. Power Data In our role as an unmetered Meter Administrator the address details are ‘virtual’ rather than Associates Ltd real. An address for the customer virtual exit point will typically be the authority office address who will be responsible for thousands possibly a few hundred thousand real exit points, which are not recorded with electricity industry systems. The real exit points are recorded in customer inventories, sometimes this is rather vague, or may be very precise. There are a number of metered street furniture supplies. These range from multiple historic street side cabinets to 50,000 recent new connections to telecoms equipment cabinets. Is not clear if or how these acquire a UPRN as they do not feature in the planning process or are perceived as properties. Therefore the local authority is unaware of their creation. As these locations have often been difficult to properly describe the ability to identify then fully on an accurate mapping product would be useful. The right hand [insecure] cabinet below is located on the Thames embankment and contains a metered electricity supply. This supply powers some lighting locally. The wooden cabinet below contains several metered supplies, which at the time of the photo had become redundant. Adjacent to the Thames again I am unclear how they would ever have an UPRN. Further along the road there are street cabinets supplying power to sump pumps and underpass lighting. ADWG/02 v0.4 Page 4 of 144 22 September 2015 ADDRESS DATA QUALITY CONSULTATION RESPONSES ESP Utilities We hold the Supply Point Address on a bespoke internal system. The address describes the Group location at which the ECV is found at the point of service termination, to aid any maintenance/replacement works required throughout its’ lifespan. It is held in PAF format and is updated as per information from Plot to Postal (P2P) documents received from the shipper, local authority or developer. New addresses are validated against the history of both the individual supply point and the CSEP as a whole. Addresses are not changed if they have previously been confirmed correct as per a P2P document. Addresses are shared with shippers at the point of registration for a new site. Once registered, the addresses are again shared with the shipper at the point a meter fit report is issued. Address data is shared with Xoserve in a SCOGES file to update their Data Enquiry service. This is a daily submission of address updates only, not a complete portfolio submission. The Change of Supply (CoS) file received from the incoming shipper mandates the inclusion of the Outcode which is validated against the information held in our system. If this does not match, the CoS is rejected. ESP Electricity The address describes the geographical location at which the meter point is located to enable Limited suppliers to identify the correct property for registration and to ensure the correct property is involved in the switching process. We hold the meter point address on our MPAS system and an internal bespoke system used for asset management purposes. MPAN addresses that are settled Half Hourly (HH) are also held in our billing system for site specific billing purposes. In MPAS and our assess management system, the address is held in Standard Address Format (SAF) and is updated as per information from Plot to Postal (P2P) documents received from the supplier, local authority, developer or Independent Connections Provider (ICP). In our billing system, the address is not held in either SAF or PAF as it is not used by the ADWG/02 v0.4 Page 5 of 144 22 September 2015 ADDRESS DATA QUALITY CONSULTATION RESPONSES industry to validate such processes as supplier switching, initial registration etc. It is only used on the HH invoices sent to Suppliers. In our experience, suppliers do not validate the addresses on HH DUoS invoices. New addresses (including address updates) are validated against the history of both the individual metering point and the distribution network as a whole. Addresses
