ENTSOG Implementation and Monitoring Report 2017 - Balancing Network Code

2.7.5 Establishing a Forecasting Party

The forecasting party is responsible for forecast- ing a network user’s non-daily metered off-takes and where appropriate its subsequent alloca- tion. After prior consultation with TSOs and DSOs concerned, BAL NC foresees designating a forecasting party by balancing zone. This may be a TSO, a DSO or a third party. Table 6 below illustrates that 19 countries reported designating a forecasting party.

The Netherlands reported that so-called EDSN serves as the forecasting party. In Romania and Estonia, it is still in progress while in four coun- tries (BG, EL, SE and SK) the designation of a forecasting party is not currently foreseen. In Sweden network users currently have agreed that they will forecast themselves. Bulgaria stated that, since they have variant 1, it does not require a forecasting party. Greece stated that there are no non-daily metered offtakes. 6 coun- tries (CZ, DK, FR, IE, NL, UK-GB) have a fore- casting party which has reported on the accuracy of the forecast of NDM-off takes.

4 countries have a third party for the forecasting of the NDM consumption.

In Austria the Third Party is the Distribution Area Manager (DAM). In Czech Republic the fore- casting task is fulfilled by the Market operator (OTE), which is an independent subject on the market. In Spain ENAGAS in its role of the Tech- nical Manager of the System must define the demand forecast in collaboration with the DSO and TSOs and their networks consumers.

2.7.6 Cooperation of DSO(s), Forecasting party (-ies) towards TSO

Each DSO associated to a balancing zone and each forecasting party shall provide the TSO in the respective balancing zone with the informa- tion necessary for the information provision to the network users. It includes inputs and off- takes on the distribution system.

20 countries (AT, BE/LU, CZ, DE, DK, ES, FR, HR, HU, IE, IT, LT, LV, NL, PL, PT, SE, SI, UK-GB and UK-NI).) reported that the TSO has cooper- ated with the DSO and forecasting party to define the information its format and the providing pro- cedure in order to ensure the due provision of information by the TSO to the network users. 5 countries have not done it: BG, EE, EL, RO and SK.
