The price of coal is the lowest it has been in 12 years, according to npower’s daily market report.

It is currently trading at $53.2 a tonne (£33/tonne).

The weakness is due to an increase in supply and a reduction in demand from China and the US, the report claims.

The UK gas system is well supplied again this morning due to high LNG flows. The linepack is currently forecast to close 6mcm long.

Sarah Astley from npower’s optimisation desk said: “Langeled flows remain subdued at 18mcm with the unplanned outage at Troll gas field continuing however this is currently expected to be rectified by tomorrow.”

LNG flows from South Hook remain high at 60mcm with four tankers expected to dock at the port next week.

Ms Astley added: “There is little change to the power system today with the forecast peak margin remaining above 10GW.”

Wind generation has reduced back to below 1GW however it is forecast to increase through the day to a peak of more than 4GW this evening.

Oil is trading below $49 a barrel (£31/Bbl).
