LONDON (Reuters) - Britain’s National Grid warned on Monday the country’s electricity supply margins are expected to be tight this week.

“We’re forecasting tight margins on the electricity system this week (from tomorrow onwards) owing to a combination of weather-related factors and unavailability of power sources over periods of the day with higher demand,” National Grid Electricity System Operator (ESO) said via twitter.

Several of the country’s nuclear power plants are currently offline, while there are also forecasts for low output from Britain’s wind farms over the coming days.
