8.2.3 DEMAND

As for demand throughout Europe, winter situations of one day and 14-day duration were taken into account. For the high daily demand the sum of demand from design case scenarios from TSOs constitutes the reference scenario. For the 14-day high demand scenarios, a similar approach is applied as for the one day peak situation, but starting from the so-called 14-day uniform risk 1) as defined in TYNDP 2013–2022. In addition to high demand also cases marked with an average daily demand are considered mainly to assess the level of market integration under different supply patterns. Variants on the reference scenario for daily peak demand are created by consider- ing peak demand in one Region and average winter demand in all other Regions (with Regions for this specific purpose defined as North West, CEE, and Mediterra- nean). This is a new “Regional” element introduced in GRIPs simulations, at this stage not considered in TYNDP, which takes a more general overall approach. The underlying rationale justifying this Regional approach is to assess infrastructure utilization should gas demand be highly differentiated across different European macro-areas for climatic or other (for example, economical linked) reasons. The table below lists the EU countries as they are grouped in the three macro-areas:

NORTH WEST

MEDITERRANEAN CENTRAL

EASTERN EUROPE

Belgium

Greece

Austria

France

Italy

Bulgaria

Germany

Portugal

Croatia

Ireland

Spain

Czech Republic

Luxembourg

Fyrom

Netherlands

Hungary

Switzerland

Poland

United Kingdom

Romania Serbia Slovakia Slovenia
