Wind generation has increased to 4.2GW, according to npower’s daily market report.
Gemma Bruce from npower’s optimisation desk said it is much healthier and stands at 13% of the stack.
Forecasts suggest wind levels will remain high tomorrow before tailing off at the start of next week.
Gas-fired generation has eased considerably, displaced by the high levels of wind and lower demand “which is typical for a Friday”, Ms Bruce added.
Imports from the continent continue to be at full capacity in the direction of the UK.
The gas system has opened in length with the linepack currently forecast to close more than 12mcm long.
Ms Bruce went on: “CCGT demand is considerably lower than earlier in the week driven largely by increased wind generation.
“However, forecasts indicate an increase on Monday which will result in a tighter system and means there is less gas available for injection.”
The euro has remained at its weakest point against the pound in eight years as there continues to be uncertainty surrounding Greece, she added.
The £1 is now worth €1.4 euros which is 3.45% higher than last week.
