标题： Impacts of EPA's Finalized Power Plant Greenhouse Gas Standards

摘要： 《通胀削减法案》为清洁电力、氢气生产和碳捕集与封存的部署提供补贴，这可能促使其他联邦、州和地方政策制定者采取额外行动以减少排放。 2024年由环境保护局（EPA）最终确定的发电厂规则是这种互补政策的一个例子。 这些规则设定了排放强度标准，而不是技术强制要求，这意味着发电厂业主可以选择多种技术及控制选项，只要满足排放标准即可。 这种灵活性使得电力系统建模变得重要，以了解这些法规的潜在影响。 我们下面报告了对EPA发电厂规则的多模型分析，可以提供及时的信息，包括对其他国家和州在排放影响、电力脱碳政策设计、电力部门投资和退役、成本影响以及负荷增长方面的信息。 我们还讨论了相关的技术、政治和法律不确定性。 显示英文摘要

摘要： The Inflation Reduction Act subsidizes the deployment of clean electricity, hydrogen production, and carbon capture and storage, which could enable additional actions by other federal, state, and local policymakers to reduce emissions. Power plant rules finalized by the Environmental Protection Agency (EPA) in 2024 are one such example of complementary policies. The rules establish emissions intensity standards, not technology mandates, meaning power plant owners can choose from a range of technologies and control options provided that emissions standards are met. This flexibility makes electricity systems modeling important to understand the potential effects of these regulations. We report below a multi-model analysis of the EPA power plant rules that can provide timely information, including for other countries and states, on emissions impacts, policy design for electricity decarbonization, power sector investments and retirements, cost impacts, and load growth. We also discuss related technical, political, and legal uncertainties.
