Permits Issued-Turbine Purchase and Interconnection <br /> The order for the turbine will be placed following the issuance of permits and the power purchase <br /> agreement.At the same time Xcel will be authorized to complete the power line extension required <br /> to reach the site, and install the transformer. The turbine will be delivered within 6 months of the <br /> order. <br /> Construction <br /> Construction on this site will best be performed either in the early spring or the fall. At these times <br /> the river flows are low but temperatures are high enough to successfully place concrete and <br /> perform construction activities. Construction will begin with preparing the bay for the installation <br /> of the turbine, raising the existing concrete side walls and constructing a new wall behind the radial <br /> gate. During construction,the radial gate will seal the area from water entering the work area and a <br /> small cofferdam will be installed to dewater the downstream side of the turbine. The stilling basin <br /> will also be constructed at this time by excavating and lining a small pool below the existing grade <br /> at the exit of the turbine.When the turbine arrives on site,the civil infrastructure will be completed <br /> and ready for the turbine to be installed. Turbine installation is expected to be completed within a <br /> few days,including the interconnection to the grid. <br /> Commissioning <br /> Immediately following the installation of the turbine,the facility will be commissioned. Testing will <br /> occur with the manufacturer as required by the utility. From this point forward the turbine will be <br /> producing electricity for the Water Users. <br /> IMPLEMENTATION SCHEDULE <br /> •FERC Exemption <br /> June 2011- December 2011 <br /> •CWCB Loan Feasibility <br /> •Power Purchase Agreement <br /> December 2011- March 2012 •CWCB Loan <br /> •N EPA Permitting <br /> •Final Design <br /> March 2012-October 2012 ;_ *Turbine order placed <br /> •Interconnection Construction <br /> October 2012 April 2013 •Construction of Civil Infrastructure <br /> •Installation of Turbine <br /> November 2012 -April 2013 •Commissioning of Facility <br /> Rio Grande Canal Water Users Association I Project Description 8 <br />
