National Grid Winter Outlook 2015/16 report: maximum potential delivery of gas supplies significantly higher than the peak demand forecast

Electricity margins are manageable with a range of tools available to keep the system in balance.

LONDON, 16-10-2015 — /EuropaWire/ — National Grid has today published the Winter Outlook 2015/16 report, looking ahead at the picture of supply and demand for both the gas and electricity systems for the coming winter. It follows consultation with the energy industry during the summer.

The report is published by National Grid in its role as electricity system operator and as owner and operator of the gas transmission infrastructure in GB.

The peak transmission system demand forecast, used for calculating the winter margin for the coming winter is 54.2 Gigawatts, a slight increase from last year.  There has been no change in the position for generation since the Winter Review was published in July.   The de-rated margin figure for winter 2015/16 is 5.1% which equates to a loss of load expectation of 1.1 hours – well within the Reliability Standard set by the Government.

Additional balancing services of 2.4 GW have been contracted for the winter period to be available to manage periods of peak demand.   This includes 133MW coming from businesses who have signed up for reducing demand at peak periods if called on, in return for payment.

Cordi O’Hara, Director of UK Market Operations said:

”Electricity margins are manageable throughout the winter period and we believe we have the right tools in place to manage the system.   This includes using the 2.4 GW of additional balancing services that we have ready in place for times of highest demand.

“On the gas side, supplies are expected to be comfortable this year, thanks to good availability of liquefied natural gas on the global market and stable flows from the North Sea and Norway.

”Gas demand for the winter period is expected to be broadly in line with last year, showing a slight increase to 48.6 billion cubic meters (bcm).  Peak daily demand is forecast to be 465 million cubic metre (mcm).

The maximum potential delivery of gas supplies, including from storage is 613 mcm, which is significantly higher than the peak demand forecast.
