Emissions standards remain a critical policy option that states can use to improve air quality and achieve climate goals, and since many larger sources of air pollution have been reduced significantly, regulating building emissions makes sense as a next step toward… View Summary +
Growing demand for electricity in buildings is creating new opportunities and challenges for electric and natural gas planning. Planning processes for the electric and gas systems are largely separate, and only a few jurisdictions have started to examine how they… View Summary +
Energy-insecure households must sometimes make difficult choices between maintaining safe indoor temperatures and electricity and providing essentials like food and medical care. At the same time, technology can offer an opportunity to help these households better manage their bills,… View Summary +
本文探讨了电动汽车充电分时电价的优化设计，提出了三个主要改进方向： 涵盖系统长期边际成本：当前的分时电价设计主要基于负荷或净负荷曲线，未能充分反映全面的系统成本。建议将长期成本纳入考虑，包括发电容量和输配电容量的扩建费用。文章特别强调了配电网扩容成本的重要性，建议将未来配电网扩容费用纳入分时电价设计。 释放分时电价的空间信号：目前的省级统一分时电价无法反映各地区电网运行的独特情况。建议将分时电价细化到更小的行政区域，甚至以变电站或馈线供电区域为单位。这有助于缓解电动汽车低谷期扎堆充电现象，并更好地反映配电网运行状况。 增强分时电价的时间信号：提出采用更灵活的时变电价结构，如紧急尖峰电价（Critical Peak Pricing-Variable）和紧急尖峰节电返利（Critical Peak Rebate）。这些方法可以更精准地反映电能成本的时间变化，并通过日前通知机制引导用户调整充电行为。 这些改进对于优化电网运行和投资具有重要意义。同时，这些建议不仅适用于电动汽车充电，也可广泛应用于其他需求侧资源管理。 本文首刊于《南方能源观察》，2024年12月20日… View Summary +
Earlier this year, the U.S. Department of Energy announced $24 million in funding to train workers without four-year degrees to enter the clean energy workforce. Governors from 22 states and two U.S. territories aim to train 1 million… View Summary +
Virtual power plants (VPPs) have received wide attention in China from central government agencies, provincial governments and, in some cases, municipal governments. Central and provincial policy directions have called for broader adoption of VPPs and successful programmes have been piloted. View Summary +
In late 2023, China’s National Development and Reform Commission (NDRC), established a new capacity payment mechanism for coal power generators. A capacity payment is an annual payment per megawatt of available capacity that is paid regardless of how many… View Summary +
On September 17, European Commission President Ursula Von der Leyen included a remarkable point in her mission letter for the incoming Energy Commissioner — advance the system integration of solar and wind by improving locational price signals. How could that… View Summary +
“We should be creative, and we should accommodate the needs of every community to open up the process. We should make it easy and accessible for every citizen to participate.” As this quote from the late Rep. John Lewis emphasizes,… View Summary +
Can states team up to better understand the benefits and challenges that efficient electrification through heat pump adoption can produce for their citizens and economies? Earlier this fall in the first in a series of webinars, Federal Dollars, State… View Summary +
