电力行业耗煤约占中国每年煤炭消费总量的一半。为此,中国要实现空气质量治理方面的宏伟目标,落实在煤炭消费控制、能源效率、可再生能源和碳排放方面的政策,电力行业必须在政策、法规、市场和经营模式方面做出改变。 2015年3月,中共中央和国务院发布了《关于进一步深化电力体制改革的若干意见》的政策文件,强调电力体制改革的必要性,可以促使电力行业朝着降低排放、提高运营效率的方向发展。 本报告从4方面提供了建议,用于提高可再生能源和终端能效的利用,并推动电改方案的实施。本文基于国际经验,重点讨论了使电力企业(特别是电网公司)的行为与政府减排目标相一致的各项激励机制。我们认为中国可以从其他国家的经验教训中获益,同时兼顾中国的特殊国情。这些建议包括 1)改革上网电价机制,改善发电企业的调度,2)建立电网公司激励机制,更好地支持可再生能源发电的并网,3)在新的“输配电价”改革框架内,支持终端用户的需求侧资源,4)综合资源规划的第一步是试点新的燃煤电厂的审批程序,要求与各种能效资源进行比较。 以上全部措施均侧重于利用市场和激励机制来解决当前挑战,这有两方面效益:帮助中国电力行业解决主要问题,特别是以更经济的方式达到政府在减排、空气质量和煤耗控制方面的宏伟目标;同时维持低成本和可靠的电力供应,促进中国经济持续增长。我们强调,应将这些解决方案与其他当前考虑的行动和政策一起协同使用。… View Summary +
Collaboratives for energy efficiency have a long and successful history and are currently used, in some form, in more than half of the U.S. states. Collaboratives can be useful to gather stakeholder input on changing program budgets and program changes… View Summary +
Deutschland hat den Anspruch, eine kosteneffiziente, umweltfreundliche und sichere Energieversorgung zu gewähren. Allerdings schließt Kosteneffizienz auch die optimierte Bereitstellung der nachfrageseitigen Ressourcen im Verhältnis zu den angebotsseitigen Ressourcen (inklusive des Netzes) ein. Dieser Aspekt ist in der nationalen Effizienzdebatte bisher… View Summary +
In China, generator dispatch—which largely determines how the vast fleet of power plants are used on an hour-by-hour basis—has long been inefficient and a major obstacle to meeting China’s air quality and clean energy goals. In addition to the curtailment… View Summary +
Kontekst europejski: W większości krajów europejskich ekstremalnie wysokie temperatury wywołały presję na krajowych operatorów i system energetyczny. Presja objawiała się koniecznością podejmowania dodatkowych działań bilansujących i generowała dodatkowe koszty, np. w Niemczech operator systemu przesyłowego wyliczył je na 25 mln… View Summary +
The development of integrated, regional electricity markets is progressing rapidly in Europe and market integration is producing tangible results, evidenced by a reduction of around one-third in average wholesale prices over the period 2008 to 2012. However, while Member States… View Summary +

The National People’s Congress (NPC) adopted revisions to China’s air law on August 29th that will go into effect on January 1, 2016. Last revised in 2000, the new law is intended to respond to and reduce… View Summary +
This brief paper outlines standard approaches to utility cost allocation and explores how decisions made by regulators affect eventual rate designs (i.e., how a utility’s revenue requirement is apportioned among customer classes).
