去年我省新增火电装机规模创新高
Xin Hua Ri Bao· 2026-01-06 00:22
近年来,以风、光为主的新能源跃居省内第一大电源,火电虽不再是"主力电源",但依然是重要的 支撑性、调节性电源。去年8月23日晚,江苏电网经历了一个典型时刻:新能源出力仅为219万千瓦,而 省内7960万千瓦主力燃煤机组中开机容量达7725万千瓦,运行机组平均负荷率超过96%,出力占比达到 省内主力电源总出力的85%,有力保障了夜间用电高峰时段的电力供需平衡。据悉,为提升供电可靠 性,江苏自2022年以来先后公布了两批次"先立后改"煤电项目和"十五五"中后期保障性调节性煤电项 目,总规模达2394万千瓦;加上此前已批准的国信射阳、国信滨海、华能通州湾等煤电项目和多台燃气 机组,全省计划新建火电总装机容量达3394万千瓦。截至目前,已有1380万千瓦容量建成投产,其中约 七成位于电力需求旺盛的苏南地区,显著缓解过江输电压力,为区域经济社会发展提供能源保障。 随着2025年12月30日国信靖江发电有限公司4号机组、江阴利港发电有限公司10号机组相继投产, 我省当年新增火电装机规模达1040万千瓦,创下近20年来最高纪录。 据国网江苏电力预测,迎峰度冬期间,煤电顶峰出力将达8450万千瓦,同比增长11.5%,可为预计 ...

“GDP超日本”,印度世界第四含金量几何?
Huan Qiu Shi Bao· 2026-01-05 22:52
Economic Overview - India's GDP has reached approximately $4.18 trillion, surpassing Japan to become the world's fourth-largest economy, with projections to grow to $7.3 trillion by 2030 [1][2] - The growth trajectory suggests India may overtake Germany within three years, becoming the third-largest economy globally [1] Consumption and Demographics - A significant driver of India's economic growth is its demographic advantage, with consumption contributing nearly 55% to 60% of GDP [1] - The country has recently become the most populous in the world, with over a quarter of its population aged between 10 and 26, which is expected to bolster consumer spending and investment [1] Government Policies - The Modi government's "Production-Linked Incentive Scheme" aims to stimulate growth by incentivizing local manufacturing in strategic sectors such as electronics, defense, and pharmaceuticals [2] Economic Growth Rate Concerns - Despite reported growth rates of 8.2% for the second quarter of FY2025, some economists argue that the actual growth rate may only be between 2.5% and 3% due to discrepancies in data collection and economic modeling [4][5] - Critics highlight that the reliance on outdated benchmarks and the exclusion of informal sector activities may distort the true economic picture [4][6] Structural Issues - A review of 22 core economic indicators revealed that only 9 showed growth, indicating underlying structural issues within the economy [6] - Key sectors such as mining and energy are underperforming, with mining growth nearly stagnant at 0.04% and electricity demand declining to a growth rate of 4.4% [6] Comparison with Japan - While India's nominal GDP exceeds Japan's, the quality of growth is questioned, as India's expansion is largely driven by the service sector rather than a robust industrial base [6] - India's per capita GDP of approximately $2,800 suggests that the economy is still in a phase of scale expansion without sufficient depth in industrial development, highlighting a significant gap compared to mature East Asian manufacturing economies [6]
绿电发得出更要用得好
Jing Ji Ri Bao· 2026-01-05 22:39
为推动能源转型,实现"双碳"目标,我国已建起全球最大的可再生能源体系。但能源转型的深层考验, 不仅在于绿电发得出,更在于用得好。2025年底召开的中央经济工作会议提出,扩大绿电应用。只有让 绿电真正融入生产生活,才能实现绿电的环境价值,支撑经济社会发展全面绿色转型。 理解"扩大绿电应用"的紧迫性,先要把目光投向全球。欧盟碳边境调节机制于2026年1月1日起正式实 施,如果我国企业不能对钢铁、水泥、化肥等产品提供明确的绿色生产证明,就可能面临高额关税,甚 至被挡在市场门外。绿电正成为国际贸易的全新通行证,关乎中国制造的全球竞争力。未来,不用绿电 可能就意味着"丢订单"。 扩大绿电应用,要从技术创新与市场机制上发力。大力发展储能技术,让绿电可以存起来;建设智能电 网,让绿电可以流动得更顺畅。只有解决了技术瓶颈,绿电才能真正成为主力电源。持续建设全国统一 电力市场,让绿电交易像买菜一样方便。同时,推广绿证制度,让每一度绿电都有据可查。此外,还可 以通过财税、价格等政策,让用绿电的企业尝到甜头,让发绿电的企业看到希望,形成共赢格局。 扩大绿电应用,是能源革命的"临门一脚"。"发得出"绿电,展现了我国作为新能源制造和建 ...
