The spring weather may be taking its time to arrive, but Pettigrew is already turning his mind to next winter, with plans afoot to expand the flexibility service. Those “products” were new technical tweaks that National Grid added to the formerly monolithic power system: a demand flexibility service, which paid consumers to shift their energy use away from periods of high usage, and contracts to keep coal plants on standby, at a cost of up to £420m. “The weather was relatively mild and when we did see cold periods, the products that we developed were very useful.”
“We came through the winter remarkably well,” Pettigrew says, in deep Welsh tones. The weather was relatively mildĪs it turned out, worries that Vladimir Putin would halt Russian gas supplies into Europe did not materialise and cold snaps were not prolonged, so the continent’s gas storage caverns could remain well stocked. We came through the winter remarkably well. Last autumn, National Grid voiced concerns that Britons could experience blackouts as well as wallet-busting bills during the coldest months.
Pettigrew has just ridden out a tense winter, marked by people having to choose between heating and eating and talk of power cuts.
