Unprecedented load was met by record output from hydro and solar, ensuring coal-fired generation fell slightly compared with the same period a year earlier, showcasing the rapid transformation of the system.<\/p>\n<p>Total generation increased to a record 883 billion kilowatt-hours (kWh) in July from 846 billion kWh in the same month in 2023 and 806 billion kWh in 2022, according to the National Bureau of Statistics. Much of the increase was down to a long period of exceptionally hot weather in eastern regions, especially province-level areas lying on the lower reaches of the Yangtze, including Shanghai, Zhejiang, Jiangsu and Anhui.<\/p>\n<p>Daily temperatures at Nanjing in the Yangtze Delta averaged 30.4 \u00b0C compared with 28.7 \u00b0C a year earlier and about 2.5 \u00b0C above the long-term seasonal norm. Nanjing temperatures have been above normal in 42 of 50 days since the start of July, pushing airconditioning and refrigeration demand to a record. The delta is home to 237 million people, 17% of the country\u2019s total population, and accounts for 24% of national economic output, making it the largest load centre.<\/p>\n<p>As a result, regional heatwaves can drive peak consumption across the entire national transmission network and draw in power from provinces to the west and south. Several cities and provinces in the delta called for conservation during the heatwave to lower electricity demand. But overall the transmission system coped because record consumption was more than matched by huge increases in hydro and solar generation in other parts of China.<\/p>\n<p>Nationwide hydro generation increased by 45 billion kWh compared with the same month a year earlier while output from solar farms was up by 10 billion kWh with a smaller increase from wind farms of 5 billion kWh. The result was that thermal generation, almost all from coal, declined by 25 billion kWh compared with July 2023, despite record electricity demand. Unprecedented amounts of hydro power were transmitted from dams on the middle and upper reaches of the Yangtze eastwards to the delta.<\/p>\n<p>Hydro generation surged to a record 166 billion kWh in July from 121 billion kWh in the same month a year earlier, easily passing the previous seasonal record of 146 billion in 2022 and 2020.<br \/>\nAfter the drought lasting from the middle of 2022 to the end of 2023, plentiful monsoon rains enabled generators to make full use of newly commissioned cascade dams on the Yangtze system for the first time. Even now, enormous volumes of water are still impounded behind dams and in seasonal reservoirs for flood control, which is likely to sustain hydro generation at record seasonal levels through August and into September.<\/p>\n<p><a rel=\"noopener\" href=\"https:\/\/www.reuters.com\/business\/energy\/chinas-record-hydro-solar-cut-coal-power-during-heatwave-kemp-2024-08-20\/\">Read more &gt;&gt;<\/a><\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.reuters.com\/business\/energy\/chinas-record-hydro-solar-cut-coal-power-during-heatwave-kemp-2024-08-20\/\">Reuters<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/vaufien\/chinas-record-hydro-and-solar-cut-coal-power-during-heatwave\/\">China\u2019s record hydro and solar cut coal power during heatwave<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[758,482,4750,1332,606,607,608],"class_list":["post-133190","post","type-post","status-publish","format-standard","hentry","category-news","tag-china","tag-energy","tag-hydro","tag-solar","tag-vau_viikkokatsaus","tag-vauen","tag-vaufien"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/133190","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=133190"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/133190\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=133190"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=133190"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=133190"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
