British wholesale gas prices surged to a seven-year high on Friday after one of the country’s main import gas pipelines was temporarily shut due to a technical fault.
The halt in production added to concerns over the UK’s gas stores, which are already running low due to the continued cold weather and few cargoes of liquefied natural gas.
Gas prices for within-day delivery rose to 150p a term, more than 50 per cent above Thursday’s closing price, after the UK-Belgium Interconnector was shut. A water pump failure forced the shutdown of the pipeline at about 7am, the operator said, adding that it “places the highest emphasis on safety and gas supply and is taking immediate action to correct the issue”.
The Interconnector announced it had resumed flowing after midday but at a reduced rate. Within-day gas prices fell back to 102 pence a therm.
The pipeline provides one of the main sources of imported gas for the UK whose domestic supplies are dwindling given the cold weather. An analysis by Reuters showed the country could run out of stored gas by April 8 based on the fall in reserves seen since the cold spell began at the start of March.
The Met Office is forecasting that the cold weather will last until April, fuelling concerns over the UK’s gas supplies.
SSE, one of the largest electricity suppliers, said on Thursday that the government was underestimating the risk of a power shortage in coming years.
“The government is significantly underestimating the scale of the capacity crunch facing the UK in the next three years,” said Ian Marchant, SSE’s chief executive. “There is a very real risk of the lights going out as a result.”
Britain’s heyday as a significant producer of oil and gas from the North Sea is long gone. Energy imports exceeded UK production in 2011 for the first time since 1974, according to government figures. LNG imports, mainly from Qatar, became an increasingly important source of supply. In 2011, they made up nearly half of British gas imports, from 2.25 per cent four years previously in 2007.
However, they dropped sharply in the past year, accounting for 27.7 per cent of total gas imports compared with 46.8 per cent in 2011. The decline was partly due to lower demand because of the recession, but the overriding factor was seen to be LNG cargoes heading east because Asian buyers are prepared to pay more.
Less LNG means the UK has become heavily dependent on imports from Belgium and Norway. Gas prices already spiked to similar levels earlier this month when a power cut at a Norwegian gas processing plant earlier cut production and exports to the UK.
The Department of Energy and Climate Change said it took “gas security and the risk of harmful price spikes seriously”.
“We are working with Ofgem to review our market arrangements to ensure they continue to provide secure supplies to consumers,” it added.
