Concord New Energy Output Slides 9.24% in July as Wind and Solar Both Retreat
Steeper than the declines seen in spring, the July figure points to deteriorating wind conditions and a grid-absorption problem squeezing Chinese renewable operators.
Concord New Energy Group's total attributable power generation fell 9.24% year-on-year in July 2026, with both wind and solar assets recording declines — the steepest the company has reported this year, exceeding the 5.28% and 5.43% year-on-year drops recorded in April and May 2026.5
The spring numbers were already weak. Concord generated 733.77 gigawatt-hours in May 2026, down 5.43% from 775.89 GWh a year earlier, following a 5.28% fall in April 2026. Wind power specifically declined 3.4% in May, according to the company's monthly filing.5 The deterioration to 9.24% in July suggests conditions worsened rather than stabilised as summer progressed.
For investors in Chinese renewable operators, the distinction between a capacity problem and a resource problem is commercially significant. Concord's installed base has not contracted. The declines reflect weaker wind speeds, lower solar irradiation, or grid constraints that limit how much output can be delivered, all of which compress revenue without reducing fixed costs.
Weak wind has been a national issue in China this year. Centre for Research on Energy and Clean Air data estimated total Chinese power generation rose 6.6% year-on-year in April 2026, but growth was thermal-led: weak wind, subdued solar, and extended nuclear refuelling outages pushed coal generation higher for the fourth consecutive period.1 Coal and gas output rose 3.1% year-on-year in April 2026, oilprice.com reported, even as domestic coal production fell 1%.2
Grid absorption compounds the picture. Carbon Brief analysis found China's CO2 emissions climbed 2% in early 2026, attributing part of that increase to curtailed wind and solar generation, power produced but not absorbed because transmission capacity or real-time demand was insufficient.4 For operators like Concord, curtailment reduces reported output regardless of what assets can physically generate.
Hormuz Strait shipping disruptions earlier in 2026 weighed on Chinese energy imports and reinforced coal's competitive position, contributing to coal power rebounding after its 2025 decline, CREA data showed.1
The curtailment constraint extends across Asia. In India, solar generation crossed 10% of the power mix for the first time, reaching a record 10.9% share in the first quarter of fiscal year 2026-27, yet grid limits were constraining absorption as peak demand hit 271 GW on 21 May 2026 (2026-05-21), a record 12% above the prior year's seasonal peak, according to a CREA quarterly snapshot reported by Asian Power on Tuesday (2026-08-04). India's installed solar capacity stood at 162 GW by June 2026, within a total installed power base of 549 GW.6
Australia offered a cleaner result. Rystad Energy senior analyst David Dixon reported utility-scale solar and wind assets generated a combined 4.6 TWh in May 2026, up 10% from 4.2 TWh in May 2025, with no equivalent curtailment drag in that data.3
Concord's August monthly filing, typically published in early September, will be the first indication of whether July was a weather-driven outlier or the start of a prolonged deterioration. China's renewable capacity additions have outpaced grid integration, and until transmission infrastructure catches up, operator output will remain subject to curtailment regardless of how much wind and sun assets actually receive.
