Key Trends
For the first 11 months of FY 2020-21, the DEC produced 62,470 MWh more than the same period of
FY 2019-20. This resulted in approximately $124.1 million more in revenues and $25.3 million more in
total expenses than the same time in the previous fiscal year. These increases are a result of the
Winter Storm Uri event in mid-February 2021.
The DEC Gross Margin as of August 31 was $108.0 million which is $95.2 million higher than budgeted.
(Gross Margin = DEC Revenue –Fuel Cost –Variable Operating & Maintenance Cost).
As a result of the February storm, the DEC projected expenditures have been increased by $29.1
million. Fuel expenses account for $28.8 million of this increase.
