Objectives The objective for Phase 1 of the project is to demonstrate the suitability and accuracy of ultrasonic meters for use on the UK distribution networks. The objective for Phases 2 to 4 of the project is to work collaboratively with the other GDNs to develop the existing network demand software model to provide accurate, calculated low flow data across the network. This will allow the networks to provide unconventional gas developers with robust, year round, demand data to allow investment decisions and de-risk entry connection contracts. Actual low flow (summer 2016/17) demand data will be monitored and recordedThe existing network flow modelling software will have been recalibrated, utilising actual demand data, to accurately predict demand during periods of low flow demandThe recalibrated software model will have been validated against actual flow conditionsThe suitability of ultrasonic meters for the measurement of low flows will have been established.
Abstract There has been an increase in potential production of on-shore unconventional gas sources GB in recent years. This brings potential benefits in terms of security of supply, facilitation of the transition to a low carbon economy and direct customer benefit from access to the wider energy market. However, there are significant challenges to address if these benefits are to be realised Key amongst these is how GB’s gas transportation system and the associated commercial and regulatory framework can be most efficiently utilised, developed and operated to support these developmentsOne major challenge that needs addressing is establishing accurate low flow demands across the UK distribution networks. This is needed to provide unconventional gas developers with robust gas demand data to help inform their investment decisions and network entry agreements. The "as is" position is that network analysis uses proprietary modelling software based on peak gas demand, which makes mathematical assumptions of both flow and pressure to calculate capacities at differing demand scenarios. Whilst the gas flow through the network has come entirely from the NTS, low flow conditions haven’t needed to be accurately established, as the main criteria for the network design is the high flow conditions. However, the onset of unconventional gas sources requires distribution network operators to provide developers with accurate, robust flow and pressure data for all operating scenarios. Distribution network operators need to develop their existing network analysis methodology to establish the true network capacity to determine the safe, efficient and acceptable profiles for injection rates from unconventional gas producers in advance of sanctioning applications for network entry agreements. In 2014 NGNs were unsuccessful in their NIC ‘T-Shale’ project bid. OFGEM requested that the original NIC bid should be broken down into smaller more manageable NIA projects. This project is the second of three smaller NIA projects. Northern Gas Networks will lead a phased programme of works to develop the existing flow modelling software to provide accurate, robust flow demand data for low flow (summer) operating conditions. This will be achieved by undertaking the following programme of works: Phase 1 - Trialling ultrasonic flowmeters to confirm accuracy and suitability for measuring low flow network operating conditionsPhase 2 - Identifying suitable locations within the NGN network to provide a representative cross section of the community architecture across the NGN networkPhase 3 - Installation of flow meters at the locations identified to provide actual flow data during summer (low flow) operating conditionsPhase 4 - Utilising the actual low flow data gained from the flow metering phase to develop the existing flow / demand modelling softwareDue to the scale and value of the project it is proposed that Northern Gas Networks undertake the delivery of Phase 1 and will then invite other GDNs to collaborate in delivery of phases 2 - 4 of the overall project scope.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
