Unseasonably high temperatures during parts of April and May saw summer demand drop below seasonal normal. Since then NTS demand returned to expected levels and stayed consistent compared to levels

  • f demand seen

last year.

NTS Demand

slide-17
SLIDE 17

17 National Grid

With gas year 2017- 18 now concluded, demand profiles for the summer remained largely consistent compared to last year The exception to this was IUK exports, which were lower than last year, particularly during the first half of Summer.

Whilst most sources

  • f supply remained

consistent compared to last year, supplies from LNG reduced significantly. Relatively high gas prices in the Asian markets could be a key driver for this change.

Proportionally, there has been less gas supplied to the NTS in the North, when compared to last Summer.
