TCAAP Energy Integration Resiliency Framework <br />Energy Source Implementation <br /> <br /> <br /> 38 <br />For the proposed initial CHP, the Project Team assumed that a gas- <br />fired reciprocating engine genset could provide 335 kW of electric <br />power year round with approximately 1,372 MMBtu/hr of waste <br />heat that would be available throughout the year. The waste heat <br />would be utilized to offset hot water production in the existing <br />buildings’ boilers during the winter, spring, and fall. The waste heat <br />from the CHP during the summer months would be exhausted and <br />the plant would run in simple cycle mode at a production cost <br />lower than the cost of purchased grid power. In the event that a <br />year-round process heating load is added in the Thumb, additional <br />thermal energy could be captured from the CHP and utilized, <br />improving system economics, efficiencies, and environmental <br />benefits. Figure 6 and Figure 7 provide a representative monthly <br />dispatch chart showing how the plant would provide power and thermal energy to the site. <br /> <br />Figure 6: Monthly site thermal energy production by resource <br /> <br />In the event that a year- <br />round process heating <br />load is added in the <br />Thumb, additional <br />thermal energy could be <br />captured from the CHP <br />and utilized, improving <br />system economics, <br />efficiencies, and <br />environmental benefits.
