Article 42
1. The forecasting party shall provide the transmission system operator with forecasts of network user’s non daily metered off-takes and subsequent allocations consistent with the information requirements set out in Articles 36 and 37. This information shall be provided to the transmission system operator within the time sufficient for the transmission system operator to provide the information to network users and for day ahead and within day forecasts of a network user’s non daily metered off-takes no later than one hour before the deadlines referred to in Article 36(1)(a) and (b), unless a later time sufficient for the transmission system operator to provide this information to the network users is agreed by the transmission system operator and the forecasting party. 2. The methodology for the forecast of a network user’s non daily metered off-takes shall be based on a statistical demand model, with each non daily metered off-take assigned with a load profile, consisting of a formula of the variation in gas demand versus variables such as temperature, day of week, customer type and holiday seasons. The methodology shall be subject to consultation before its adoption. 3. A report on the accuracy of the forecast of a network user’s non daily metered off-takes shall be published by the forecasting party at least every two years. 4. Where relevant, transmission system operators shall provide the data regarding gas flows within the time sufficient for the forecasting party to comply with its obligations under this Article. 5. Paragraphs 2 to 4 shall, mutatis mutandis , apply to variant 1.
