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.相关论文摘要：在天然气与电力公用事业的监管工作中，费率营收的核定通常需要开展销量调整，以反映实际天气与正常天气之间的差值。该调整流程通常被称为天气归一化（weather normalization），其目的是合理确定一套在正常天气假设下能够满足营收需求的费率标准。表征长期天气模式的正常天气数值，是天气归一化流程的关键组成部分。传统上，正常天气数值通过标准气候正常值（Standard Climate Normal，SCN）计算得到。任意给定公历日的标准气候正常值，为该公历日对应天气观测值的30年平均值。在监管流程中，标准气候正常值可能会在无意间给天气归一化调整引入偏差。本研究针对这类偏差的来源及缓解方案展开了调研。
