1. Recovery True-up – The current ECA rate includes a $3,638,173 under-recovery and the proposed rate reflects a $4,749,611 under-recovery from the period January – April 2019. 持续的回收不足状况是由于2019年1月至4月期间的实际期间成本约为1美元.11M higher than the actual recoveries for the same period. 复苏不足的部分原因是由于2019年第一季度利率的实施延迟. The Q1 2019 ECA rate became effective on February 15, 2019.

Estimated Purchases for System - 2019年7月至2020年6月系统预计采购额增加2,624,750美元，即6.2019年4月至2020年3月期间，从58,809,141美元上涨16%. 预计系统采购量的增加部分归因于Busch Ranch II于2019年11月通过购电协议（“PPA”）上线. 约74.4万美元的额外Busch Ranch II PPA费用已包括在此期间的系统估计采购中, 与未包括这些费用的上一期预测费用相比. Additionally, it is forecasted that approximately 160,与2019年4月至2020年3月的预测相比，2019年7月至2020年6月期间将购买083兆瓦时的银河官网. This additional purchase load of 160,083兆瓦时进一步增加了这一时期的估计购买量.
