The flow of Norwegian gas to northern England via the Langeled pipeline resumed on Friday, live data from Britain's system operator National Gas showed following a June 2 outage that triggered renewed concerns over energy security in Europe.

Britain's Easington import terminal received gas from Langeled at a rate of 44.5 million cubic meters (mcm) per day at 0446 GMT, up from zero on Thursday, according to data from National Gas.

Sunday's interruption of gas flows from Norway's onshore Nyhamna plant via Langeled to Easington drove Europe's benchmark gas price on Monday to 38.56 euros per megawatt-hour (MWh), its highest since December.

The outage was caused by a crack in a two-inch pipeline onboard Equinor's offshore Sleipner Riser platform, which acts as a connection between Langeled North and Langeled South.
