LONDON, March 15 (Reuters) - British wholesale gas prices fell on Friday as high output from the country’s wind farms curbed gas demand and the expectation of several deliveries of liquefied natural gas (LNG) weighed on the market.
* Within-day gas price down 0.85 pence at 38.30 p/therm by 0912 GMT.
* Day-ahead gas price down 0.05 pence at 38.75 pence per therm by 0906 GMT.
* Traders said low demand for gas from power stations had contributed to an oversupplied system, while low LNG prices in Asia had seen deliveries ramp up to Europe.
* Gas system oversupplied by 22.4 million cubic metres (mcm), with demand forecast at 224.6 mcm and flows at 247 mcm/day, National Grid data showed.
* Six LNG tankers are expected to arrive in Britain in the next 11 days.
* Asian spot prices for LNG hit a three-year low this week at $5.45 per million British thermal units.
* Peak wind power generation is forecast at 12.3 gigawatts (GW) on Friday and 10.4 on Saturday, National Grid data showed.
* Wind farms were providing 30 percent of Britain’s electricity on Friday morning, with gas-fired power plants contributing 28 percent.
* However, analysts at Refinitiv said wind power was expected to dip next week, leading to forecasts for higher gas demand from power stations on Monday.
* The analysts forecast day-ahead gas demand from power up 24 mcm/day at 67 mcm/day.
* Further out on the curve prices also slipped.
* April contract down 0.25 p at 38.65 p/therm.
* Summer 2019 contract down 0.50 at 39.05 p/therm
