SUBJECT:
Denton Energy Center (DEC) Monthly Report for July 2018 Operations
EXECUTIVE SUMMARY:
During July 2018, the DEC met all operational goals and limited the electric utility’s exposure to
extreme market prices throughout a prolonged heat wave that produced multiple records for
electricity demand.
The DEC completed testing in July and was approved by ERCOT for commercial operation on
July 11, 2018. Pipeline testing by DEC’s natural gas fuel supplier delayed the first operational
deployment until July 16. From the 16th to the 31st of July, DEC ran an average of 8 hours each
day. During this period Day Ahead prices in the peak hours between 3p.m. and 7p.m. averaged
just under $600 per MWh, enabling DEC to realize Gross Revenues exceeding $8.3 million.
Monthly emissions met all targets; emissions by type ranged between .05% and 6% of annual
permit amounts.
