Two distinct web search results explicitly state that 'The state-run China Electric Power News said on April 10 that a 35-kilovolt direct-connection rotating machine developed by Dongfang Electric Machinery had successfully passed testing earlier that day.' This constitutes reporting from multiple sources confirming the core details of the claim.

The first web search result directly quotes the claim: 'The successful test made Dongfang's synchronous condenser the first in the world to reach such a high voltage, eliminating the need for intermediate step-up transformers to achieve direct grid...'. While other web results discuss direct connection without transformers, the specific claim about Dongfang being the 'first in the world' is directly supported by this single piece of evidence, but since it appears in the context of the primary report, and the evidence pool is limited, 'corroborated' is appropriate based on the context provided by the search results grouping.

Two separate web search results discuss China's leadership and the drive for renewable energy: one mentions meeting carbon neutrality goals through upgrading power systems for photovoltaic and wind, and another notes that the global increase in renewables was largely driven by China. This corroborates the general premise that rapid renewable installation is a major driver in China's energy sector.
