TCAAP Energy Integration Resiliency Framework <br /> <br /> <br /> <br /> 22 <br />2.5.1.2. AHATS Solar PV <br />The 2009 Master Plan for AHATS produced by Jacobs Engineering identifies a two MWe solar PV <br />installation at the capped soil area west of the existing Field Maintenance Shop. This installation would <br />primarily meet a portion of the electric needs of the AHATS site, but could provide renewable electric <br />energy to TCAAP during the non-peak energy usage times at AHATS. <br />2.5.2. Combined Heat and Power <br />Combined heat and power (CHP) could be used to meet the electric needs of TCAAP and adjacent <br />properties, while simultaneously capturing the thermal energy created from electric generation to <br />meet the thermal needs of the area. This would provide a local energy generation source to the area <br />that could be disconnected from the grid in the event of a grid disruption. As the existing electric and <br />thermal energy loads are based at the AHATS and RCPW buildings, it would be optimal to locate the <br />initial CHP plant as close to those buildings as possible, with the opportunity of expanding it to meet <br />future TCAAP energy needs. This initial proposed location provides two advantages. First, having the <br />plant located near the initial load will reduce the up-front capital cost for the installation of the <br />distribution network providing thermal energy. Second, this location is near the existing and proposed <br />AHATS buildings, meaning that training operations (located in the central and northern areas of <br />AHATS) would not be negatively impacted. Additional CHP facilities could be located in the Thumb area <br />of TCAAP, or near other concentrated loads at TCAAP as development proceeds. The CHP system <br />should be designed to allow for expansion to serve the thermal needs of the TCAAP site as it is <br />developed, to align with the vision of TCAAP as a comprehensive energy program that optimizes <br />efficiencies, minimizes costs, and reduces greenhouse gas emissions. The initial system should also be <br />designed for future fuel flexibility, such as biogas integration, and the ability to meet growing thermal <br />needs of the area. <br />2.5.3. Groundwater Treatment Station <br />Approximately two million gallons per day (2 MGD) are pumped to AHATS from the groundwater <br />treatment station located on TCAAP. This pumping is required to continue until the chemical <br />remediation goals are reached for the water, which is estimated to be at least another 25-30 years. <br />This groundwater pumping can be useful to meet the energy goals of both AHATS and TCAAP through <br />the implementation of a low-temperature district energy system. <br />In addition, kinetic energy could be captured from the pumped water at the point of discharge at the <br />gravel pit on the AHATS site. The water is being pumped uphill to a point that provides energy which <br />potentially could be used for micro-hydroelectric generation. This would provide a small amount of <br />electric generation, but could be used to offset the power necessary to pump the groundwater.
