Key facts
- China curtailed 360 TWh of solar and wind power in the first half of the year.
- This curtailment represents a 49% increase from the previous year.
- Grid constraints are a primary reason for renewable energy curtailments.
- Rising coal-fired power generation contributes to renewable energy curtailments.
- Record curtailments pose a risk to investment stability in China's renewables sector.
- China increased crude oil reserves by an estimated 200,000 barrels per day in July.
- Japan faced rising import costs due to Middle East supply disruptions.
- China's oil reserve increase suggests persistent weakness in domestic demand.
- China's oil reserve increase suggests persistent weakness in refinery activity.
China's ambitious renewable energy expansion is encountering significant challenges, leading to a record 360 TWh of solar and wind power being curtailed in the first half of the year. This represents a substantial 49% increase in wasted clean energy compared to the same period last year. The primary drivers behind these record curtailments are persistent grid constraints, which cannot absorb the rapidly growing renewable capacity, and an increase in coal-fired power generation. This oversupply and curtailment situation poses a considerable risk to the stability of investments within China's renewables sector, potentially deterring future development.
