Dr Alastair Martin, chief strategy officer at demand response provider Flexitricity, said: “What we’re seeing is a warning from National Grid that they are unsure there is enough supply to meet demand. In other words, things are looking tight.
“National Grid has engaged demand-side response services such as ours to fill the gap, by turning down industrial and commercial energy usage at this critical time. Although we’ve been doing this regularly for seven years, this is the first time National Grid has used the pool of contingency reserve which we created in response to the tight winter supply margins.
We have responded by lowering consumption at commercial energy users across our connected network. For this event, we’ve engaged 46 sites, most of which have delivered by turning down building ventilation. We have several hundred megawatts across the portfolio which is ready in case things get worse. In short, we’re meeting the shortfall and keeping the lights on.”
On the possible reason for the Notification of Inadequate System Margin (NISM), Dr Martin said: “At this time of year, there are often problems at power stations because of the end of the summer maintenance season. The last time National Grid issued a NISM, seven power stations failed on the same day. This time it’s unlikely to be as serious as that. But at this time of year, we also get regular demand spikes, which can make things worse if the power stations are having trouble.”
“What we do know is that the capacity margin is tighter than it’s been for decades. It is therefore reassuring to know that services such as ours have been able to respond successfully at such short notice.”
