intended to give a snapshot of relevant DEC metrics. The dashboards highlight the following:
The Emission Charts (based on calendar year) display the May engine runtime hours,
starts, stops, monthly and annual emissions totals and limits.
DEC MWh Generation and Gross Revenue for FY 2020-21 through May 2021.
o The DEC ran 44,301 MWh more through April of FY 2020-21 compared to FY
2019-20. This resulted in approximately $120.6 million more in DEC Revenue.
A DEC financial summary showing May FY 2019-20 Actuals, FY 2020-21 Budget,
Actuals as of May 2021 and the FY2020-21 end of year projections.
o As a result of Winter Storm Uri, the FY 2020-21 year-end projections have been
updated to show a $28.8 million increase in DEC fuel cost.
The Plant Monthly Run Hour Comparison Graph illustrates the monthly plant run times.
The Key Trends section explains variances in revenues and expenses.
o Due to running more hours through May, the fuel cost was $23.2 million higher.
o The net income for the DEC through May equals $90.2 million, which is a direct
result of Winter Storm Uri in February and higher run times than forecasted
during the months of October 2020 and April 2021.
o The DEC Gross Margin through May was $102.6 million which is $101.9 million
higher than budgeted also mainly due to Winter Storm Uri. (The Gross Margin =
DEC Revenue – Fuel cost –Variable Operating & Maintenance cost.) Gross
