Division F1

Provide a brief description of the gas system of F2the United Kingdom, covering:

1. (a)

   the main gas consumption figures: annual final gas consumption (bcm) and breakdown by type of customers, peak demand (mcm/d);

2. (b)

   a description of the functioning of the gas system at national level, including infrastructure (to the extent not covered by point 1.1(b)). If applicable, include L-gas system;

3. (c)

   the identification of the key infrastructure relevant for the security of gas supply;

4. (d)

   a breakdown, to the extent possible, at national level of gas import sources per country of origin;

5. (e)

   a description of the role of storage and include:

   1. (i)

      the storage capacity (total and working) compared to heating season demand;

   2. (ii)

      the maximal daily withdrawal capacity at different filling levels (ideally with full storages and end-of-season levels);

6. (f)

   a description of the role of domestic production and include:

   1. (i)

      the volume of production with regard to the annual final gas consumption;

   2. (ii)

      the maximal daily production capacity;

7. (g)

   a description of the role of gas in the electricity production (e.g. importance, role as a back-up for renewables), including gas-fired generating capacity (total (MWe) and as percentage of the total generating capacity) and cogeneration (total (MWe) and as percentage of the total generating capacity).
