Gas and power prices have again increased in the UK, as inflated oil prices push up curve contracts and the possibility of cold weather combined with supply interruptions increases short-term prices, according to Reuters.

Gas delivery prices reportedly surged to GBP0.66 from GBP0.61 per therm, as North Sea gas flows decreased due to a field outage. The prices later subsided to GBP0.64 as the supply situation improved.

The news source reported that in the future markets, gas contracts for winter 2008 increased by 3.8 pence to GBP0.82 per therm, while baseload power contracts for the same period consolidated at around GBP73.45 per MWh.
