On 30 September, Britain paid £30 million to wind and gas generators, Octopus Energy's Wasted Wind tracker showed. Some of that money bought silence from turbines with nowhere to send their power. The rest bought gas plants that fired up to cover the gap. September alone cost £404.3 million in wind-related constraint payments, according to Octopus.
That is the problem in miniature. Wind, solar and storage are going up faster than the wires and firming capacity that deliver them, and the gap is now a line item on someone's bill. This week's developments in Britain, India, Turkey and the Congolese copper belt each put money into transmission or batteries, because generation alone has stopped being enough.
Scotland's wind, England's bill
Britain shows the cost of building first and wiring later. Briefs Finance, in a Nov. 12, 2026 piece linking to a Bloomberg report, says the National Energy System Operator expects the cost of managing the grid to top £3.9 billion next year. Constraint payments reached a record £2.7 billion through October, as NESO pays some generators to turn off and others to fire up.
Octopus says Britain had already passed last year's entire £1.47 billion bill for switching off wind farms and firing up gas plants, with three months of 2026 still to go. "We've already blown past last year's entire bill, and customers are paying every pound of that waste.," said Greg Jackson, Octopus's founder and chief executive. Rebecca Beresford, NESO's director of market, was blunter about the trend: "Constraint costs are extremely high, and they have increased since last year."
The geography explains it. Briefs Finance notes the best wind sites sit in remote parts of Scotland while most demand lies farther south, so NESO pays plants to curtail or ramp, and consumers pick up the charges. Octopus adds that some Scottish transmission boundaries, including B4, were running at just 40% of capacity because temporary upgrade works made existing bottlenecks worse. The fix itself clogs the pipe.
Relief is scheduled but not guaranteed. NESO anticipates a sharp drop after 2030 as major reinforcements move more electricity from north to south. By 2035, though, costs could surge again if generation outpaces the network. Its scenarios put the bill at up to £7.7 billion per year by 2030 at the upper end, Briefs Finance reports, and the government has warned of £10 billion by 2030, per Octopus. Octopus cites FTI analysis it commissioned showing that wholesale pricing reflecting where power is generated would let a typical household save up to £114 a year.
India builds the road
India is trying to avoid the British sequence. Reuters, as carried by Business Standard, reported that the country has approved a high-capacity corridor to carry clean power from western generation hubs to demand centres in the east. The estimated cost is nearly ₹68,800 crore ($7.34 billion), with about six years to build. The 1,150-kV system would be India's highest-voltage power network, able to dispatch far larger volumes than present 765-kV lines. Its first phase links Chhattisgarh, Odisha and West Bengal and connects to a 6,000-megawatt system carrying power from Rajasthan's Bhadla solar region.
The urgency is visible in the curtailment data. OilPrice.com, citing JMK Research & Analytics, reported that grid, flexibility and transmission constraints, plus limited battery storage, forced India to curtail as much as 118.6 GW of solar and wind capacity in September. Grid-India data put 96.9 GW of that in solar and 21.7 GW in wind. The curtailed energy equalled 1.28% of India's renewable generation that month, a small slice for now. But JMK found curtailments rose sharply between May and August versus last year, while 44.6 GW of new solar went in.
India still wants more. Reuters says it targets 500 GW of non-fossil capacity by 2030, from more than 300 GW now. OilPrice.com reports that a senior official said New Delhi plans to soon mandate state-owned utilities to add energy storage.
