Availability Estimates of Low-Cost, Dispatch-Constrained Electricity (LDE)

This dataset accompanies the report "Potential Availability of and Supply Curves for Low-Cost, Dispatch-Constrained Electricity", which provides initial estimates of the quantity and availability of the potential low-cost, dispatch-constrained electricity (LDE) resource in the United States under scenarios with high variable renewable energy (VRE) penetrations. The analysis also estimates supply curves that can be used in subsequent analysis of the opportunity to use the LDE. The estimated LDE resource could be used for various applications that value low-cost electricity and can operate at reduced capacity factors, including electrolytic hydrogen production and carbon capture. The analysis accompanying this dataset was performed in 2018-2019 to support an analysis of "The Technical and Economic Potential of the H2@Scale Concept within the United States" (https://www.nrel.gov/docs/fy21osti/77610.pdf). This dataset includes the quantity of estimated LDE resource for each hour of the year in 2050, aggregated to both the national level and the ReEDS balancing area level. As described in the accompanying report, the ReEDS model was used to project the evolution of the power sector over time. Links to the mapping of ReEDS balancing areas to states and ReEDS balancing area shape files are provided. This dataset also includes the report figure data.

本数据集配套于报告《低成本受调度约束电力的潜在可得性与供应曲线》（"Potential Availability of and Supply Curves for Low-Cost, Dispatch-Constrained Electricity"），该报告针对美国高可变可再生能源（Variable Renewable Energy, VRE）渗透率情景下的潜在低成本受调度约束电力（Low-cost, Dispatch-Constrained Electricity, LDE）资源总量与可得性给出了初步估算。本分析同时估算了供应曲线，可用于后续开展LDE资源利用机遇的相关研究。本次估算的LDE资源可应用于多种看重低成本电力且可在较低容量因子下运行的场景，包括电解制氢与碳捕集。本数据集配套的分析工作于2018至2019年间开展，旨在支撑《美国境内H2@Scale理念的技术与经济潜力》（"The Technical and Economic Potential of the H2@Scale Concept within the United States"，https://www.nrel.gov/docs/fy21osti/77610.pdf）的相关研究。本数据集包含2050年全年逐小时的LDE资源估算总量，分别聚合至国家级与ReEDS平衡区域层面。如配套报告所述，本次研究采用ReEDS模型对电力行业的长期演化进行了情景预测。本数据集同时提供了ReEDS平衡区域与各州的映射关系，以及ReEDS平衡区域形状文件的下载链接。本数据集还包含该报告的图表原始数据。
