  2. Agenda • Executive summary • Customer approach • Case studies • Keele University • St Pancras Cemetery • Samlesbury Brewery • Phase one results • Phase two

  3. Executive Summary • RIIO commitment to declare ‘off risk’ to all sub deduct networks • National Grid aim to complete project in 3 years due to associated risk • 962 known sub deduct networks were identified at GDPCR1 • Following surveys in 2008/9 each sub deduct network was assigned a qualitative risk score • Sites have been sub divided into three groups • Group 1 - 178 sites where during the 2008/9 survey no sub deduct meter was identified • Group 2 – 742 sites where during the 2008/9 survey a sub deduct network was identified • Group 3 – 42 complex sites which consist of high relative risk scoring sites or sites owned by a National Body, e.g. HM Prison, Ministry of Defence, Royal palaces

  4. Customer Approach Our approach to engage customers and provide them with ongoing service is: • A National Grid engineer will conduct a survey of each sub deduct network • Packs put together to provide the customer with further information and reference material • Central point of contact for all customer queries • Engagement with xoserve to ensure suppliers are kept up to date for billing reasons • Enduring process with xoserve implemented for sub deduct queries

  5. Case Study – Keele University This is an example of a site where the situation has changed since the installation of the sub deduct network, it effects a number of customers and further engagement is required. • 22 sub deduct meters located in a residential area within Keele University • Residential area is no longer part of Keele University and owned by housing association • Engagement has been ongoing with Keele University to discuss options that are available, further engagement with the housing association is underway • Preferred option for National Grid and Keele is to engineer out sub deduct network as per the attached picture

  6. Case Study – St Pancras Cemetery This is an example of where engineering work was required but the approach needed changing due to challenges. • Existing sub deduct meter was 500m from the primary meter • Customer did not want to formally adopt the network • Due to operational requirements the site could not be without gas • Proposed solution was to run a new service to the sub deduct meter • Work would have been disruptive and only able to be undertaken on a Sunday • Further engagement with the customer revealed that there was no longer a requirement for the sub deduct network, therefore the meter was removed and pipework bridged saving time, money and disturbance

  7. Case Study – Samlesbury Brewery This is an example of a site that have been maintaining their sub deduct network as their own and have decided to formally adopted the network • Meeting with customer onsite revealed that they had been maintaining the sub deduct network as they believed it was their responsibility • One redundant sub deduct meter has been removed since our site survey in 2008/09 • Further secondary meters had been added and the sub deduct network was still required • Customer decided to formally adopt the pipework and no engineering work was required

  8. Phase One Results • The focus for year one was to concentrate on 619 sub deduct networks. This included all of Group 1 and Group 3 with the addition of the less complex sites in Group 2. These were identified by the risk score assigned following 2008/9 surveys • 71% of planned workload was declared ‘off risk’ • 183 sub deduct networks remain at risk due to: • Access issues • Awaiting customer decision • Deferred due to site uncertainty • Re-engineering required by GDSP • Other e.g. Easement or consent to lay • 49% of total population of sub deduct networks declared ‘off risk’ in year one

  9. Phase Two • Phase two of the project commenced in April 2014 • There are 518 sites made up of the more complex sub deduct networks of group 2 and the 183 sites carried over from 2013 • ‘No access’ issues to be addressed by consulting Land Registry for proprietor information • Further engagement required with customers who are yet to make a decision
