UK gas prices rise on undersupplied system
* UK gas system seen 15.5 mcm short
* Kollsnes maintenance, strike keep pressure on prices
* Forward gas prices supported by $100 oil
LONDON, July 4 (Reuters) - British prompt natural gas prices rose on Wednesday morning as an undersupplied system pushed up prices while contracts for later delivery remained firm on the back of oil prices hovering around the $100 a barrel marker.
Gas prices for within-day delivery were trading around 57.85 pence a therm at 0930 BST (0830 GMT) on Wednesday, up 1.05 pence since Tuesday morning.
The price rise was a result of an undersupplied system and supply concerns as a result of an offshore oil and gas strike in Norway.
UK gas demand was expected to be 190.6 million cubic metres (mcm) on Wednesday, some 15.5 mcm above supplies, according to National Grid data.

Despite this, Point Carbon said that it expected gas prices to move sideways around 57.60 pence a therm rather than rise further. Continued...
