Objectives | To review the current billing and measurement arrangements and recommend potential alternative arrangements that would not be a barrier to alternative gas supplies and is fair to consumers. Inform an NIC bid Production and agreement of a study proposing alternative billing arrangements for further investigation. The basis for work to be included in an NIC submission | |
Abstract | The Flow Weighted Average Calorific Value (FWACV) billing regime was introduced in 1996/7 to reduce the quantity of unbilled energy in the networks. However, as a result of the requirement to average out the CVs of multiple entry points and the restriction that FWACV cannot be more than 1 MJ/m3 above the lowest CV entering the charging area, higher CV gases can be unbilled and lower CV providers are forced to enrich their gases to avoid the CV cap being imposed on the whole network. Bio-methane producers, for example, are enriching their small volumes of "green" and GS(M)R compliant gas with propane. Hence, the current FWACV billing regime is a potential barrier for the injection of volumes of gas with calorific values (CV) that are significantly higher or lower than the prevailing FWACV of the network. The FWACV regime also impacts on the control and movement of gas around the National Transmission System - an alternative regime may be beneficial for the Gas Transmission business and facilitate the introduction of shale gas in the high-pressure tier. Currently, measurements of CV and volume are made at network entry points and the FWACV applied to the whole network. In order to facilitate entry of new and different sources of compliant gas, an investigation into billing and measurement points closer to the point of use is required; the new billing system needs to identify all stakeholders and provide a mechanism of opening up the gas market to entry of all gas that complies with GS(M)R and network entry requirement. A feasibility study will be undertaken to investigate a different billing system. The work will involve novel network modelling from the NTS offtake to the point of use including within-day demand modelling. The results will inform the project on how variations in gas quality affect the customer at the point of use, where measurements of energy content need to be made and how accurate these measurements need to be. In parallel, work will be undertaken to survey the suitability of measurement equipment commercially available. A suitable network for a field trial will be identified and modelled. The feasibility study may subsequently be used for an NIC proposal for submission of funding in 2015.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
