Question

A report called Electric Shock: Will The Christmas Lights Go Out Next Winter? has been published by the British Infrastructure Group (BIG) of MPs , which states that the UK could be facing nationwide blackouts next winter unless radical changes are made to the UK's electricity network. They say, prices have been allowed to shoot upwards and capacity margins slashed, which are now "so tight that National Grid's emergency power deals have become the norm". Are you satisfied about the security of London's electricity supply?

It is important to me that that London's electricity supplies remain secure. Recent reviews of power station generating capacity for winter 2017/18 forecast a historically low generation margin. National Grid is expected to call upon Supplemental Balancing Reserve, a service where generators are kept on standby outside the market, and demand side measures to secure the necessary electricity supplies. This situation is not expected to reoccur in future winters as new power generation capacity is being built as a result of National Grid's Capacity Market incentive. I have asked my officers to closely monitor the situation.
