TCAAP JDA/COUNCIL MEETINGS 11/3 and 10/2014 <br />ERAB comments <br /> <br />There is a big challenge of how to design, show the economic benefits and <br />implementation of a TCAAP Sustainable Energy System. <br />• Energy savings come from efficient sustainable building design and construction. <br />• Energy savings can also come from thermal or geothermal for heating and <br />cooling and from ground or surface mounted solar installations for electrical <br />supply. <br />The white paper explains options to meet those challenges. <br />Minnesota law requires Xcel Energy to install 300 MW of solar by 2020. Xcel’s goal is to <br />install 100 MW by the end of 2016. To achieve electrical energy savings with ground <br />mounted solar installations at TCAAP, there needs to be joint cooperation between <br />TCAAP, AHATS and Xcel. <br />• The AHATS land would allow large ground mounted solar which is less than one- <br />half the installation cost of rooftop solar. <br />• Thermal and geothermal also benefits from cooperation with AHATS. <br />• Another joint ownership could be Direct Fiber Broadband. <br />The Energy Integration Resiliency Framework (EIRF) needs to show how sustainable <br />building design and standards, solar and geothermal/thermal energy use, can be a win- <br />win for TCAAP, Xcel, AHATS, the City, County, developers and customers. <br />The combination can produce a win-win for all, and make TCAAP a model energy <br />sustainable community. <br /> <br />Lyle Salmela <br />ERAB Chair
