Data for: Climate normals and weather normalization for utility regulation

Abstract of associated article: In the regulation of natural gas and electric utilities, the determination of rate revenues commonly involves a sales adjustment to reflect the difference between actual weather and normal weather. This adjustment process, commonly known as weather normalization, is required to properly determine a set of rates which yields the revenue requirement under the assumption of normal weather. Normal weather values that characterize long-term weather patterns are critical component of weather normalization. Conventionally, normal weather values are calculated using the Standard Climate Normal (SCN). The SCN for any given calendar day is the 30-year average of the associated weather observations for that calendar day. In the regulatory process the SCN can inadvertently introduce biases in the weather normalization adjustment. This study investigates the sources and mitigation of these biases.

相关文章摘要：在天然气和电力公用事业监管中，确定税率收入通常涉及销售调整以反映实际天气与正常天气之间的差异。此调整过程，通常被称为天气标准化，是为了在正常天气的假设下，正确确定一系列能够产生收入需求的税率。表征长期天气模式的正常天气值是天气标准化的关键组成部分。传统上，正常天气值是使用标准气候正常值（Standard Climate Normal，简称 SCN）进行计算的。对于任何给定的日历日，SCN是该日相关天气观测值的30年平均值。在监管过程中，SCN可能会无意中引入天气标准化调整中的偏差。本研究旨在探讨这些偏差的来源及其缓解措施。
