KONTAN.CO.ID - US natural gas futures edged up about 1% to a fresh 13 year high on Wednesday on forecasts for hotter weather and higher demand next week than previously expected, a decline in output, low wind power and record power demand in Texas.

Power demand in Texas broke the June record on Monday and Tuesday and will keep rising this week until it tops the all-time high as economic growth boosts usage and hot weather causes homes and businesses to crank up their air conditioners.

Low wind power forces generators, including those in Texas - the state with the most wind power - to burn more gas to keep the lights on.
