9 ALL CAMPUSES DESCRIPTION The University of Texas at San Antonio (UTSA) was founded in 1969 as a component of the University of Texas System. There are three distinct UTSA campus locations in San Antonio referred to as the Tri-Campuses--Main Campus (Main), Downtown Campus (DTC), and Hemisfair Park Campus (ITC). A fourth campus, Park West, will house various Intercollegiate Athletics complexes. During FY12, the first athletics complex was in early stages of construction. UTSA also has several Off-Campus properties, including a Lockhill Selma location (Institute for Cyber Security), University Heights Tech Center, Blue Star Studios, and Washington Place Building. UTSA utilities (water, gas, and electricity) are purchased from local utility companies. The University separates charges into two categories: Educational & General (E&G) and Non-E&G. E&G entities utilize resources that are used for academic instruction, research, and support of the institution s mission. UTSA does not charge E&G entities for utility usage. Non-E&G entities furnish a service to students, faculty, or staff for which charges are made that are directly related to the cost of the service. Non-E&G entities are managed as essentially self-supporting activities. UTSA charges Non-E&G entities (per Texas Administrative Code Chapter 17 Subchapter A) a portion of the utility bills based on metered consumption or square footage. Examples are residence halls, food services, student health services, intercollegiate athletics, college stores and college unions. ELECTRICITY The University of Texas at San Antonio (UTSA) purchases electricity from CPS Energy using one or more of the following rate structures: General Service (PL), Large Lighting and Power Service (LLP), Extra Large Power Service (ELP), Super Large Power Service (SLP), or Streetlighting Service State Expressway (SSE). The City of San Antonio and CPS have not opted to enter the deregulated market, however, CPS levied an electricity rate increase of 7.5% for FY11 which will be applied every two years thereafter. No increase will apply to FY12. Main Campus: The SLP rate (the lowest electric rate in San Antonio) is applied to all accounts with the exception of two; the PL rate is applied to a small roadway account and the account for parking lot #13 on east campus. Downtown: Three electric rate structures are used: ELP, LLP, PL, and SSE. Power is fed into the buildings at 13,800 Volts and is then stepped down to 480 V / 277 V at the transformer vaults. Monterey Building consumes utilities on individual accounts using both the LLP and PL rates. Hemisfair Plaza: Two electric rates apply: PL and LLP. Power is fed into the main building at 13,800 Volts and then stepped down to 480 V/277 V at the transformer vaults. Park West: Electricity consumed during FY12 was billed to the construction project. 01 FY12 Narrative.All Campuses

10 THE UNIVERSITY OF TEXAS AT SAN ANTONIO Off-Campus: The PL rate is applied to the four accounts at the University Heights leased space. Blue Star Studios consumes utilities using the PL rate. Electricity costs for the Lockhill Selma property (Institute for Cyber Security) are incorporated into the lease agreement. NATURAL GAS CPS Energy (CPS) is the primary supplier of natural gas. UTSA purchases using one or more of the following rates: Large Volume Gas (LVG), Industrial Gas (CLASS B), or General Service Commercial (G). CPS announced and levied a natural gas rate increase of 8.5% that was effective for FY11 and every two years thereafter. No additional increase will be applied to FY12. Grey Forest Utilities supplies a small amount of natural gas for UTSA s leased space at University Heights Tech Center. Main Campus: Natural gas is directed to the North Thermal Energy Plant, then split four ways and billed on four accounts at the LVG rate. Two splits go directly to the North Thermal Energy Plant for the engine generator and the boilers; one split supplies the South Thermal Energy Plant; one split supplies all other campus buildings. A separate gas line services Chaparral at the LVG rate, further divided to supply Roadrunner Café. Another gas line services Child Development Center at the G rate. Downtown: LVG and G rates apply. Hemisfair Plaza: CLASS B rate applies. All campus buildings are supplied via one main building account. There are 10 secondary accounts for the many auxiliary buildings that mainly support the annual Texas Folklife Festival. UTSA owns and operates the thermal energy plant that supplies chilled water and heating water for building air conditioning. Park West: Natural gas was not supplied. Off-Campus: UTSA does not have a specific contract for Off-Campus properties. Each property has a separate account. Standard G rates apply. WATER Water is purchased from the San Antonio Water System (SAWS) on a contracted rate. irrigation and domestic water is supplied. Both Main Campus: Two main lines (8 and 10 ) provide a co-mingled water supply. One account bills for all campus buildings, except the Child Care Center. Child Care Center has a dedicated water line and account, billed separately. Downtown: Several accounts which are separated between domestic and irrigation water use. Hemisfair Plaza: Standard rates apply. There is one account. Park West: Water was not supplied. Off-Campus: UTSA does not have a specific contract for Off-Campus properties water. Water is incorporated into the lease agreement. 02 FY12 Narrative.All Campuses

16 THE UNIVERSITY OF TEXAS AT SAN ANTONIO MAIN CAMPUS DESCRIPTION The Main Campus is located on 600 acres in the northern outskirts of San Antonio near the intersection of Loop 1604 and Interstate 10. Since 1973, when the core buildings were built, Main Campus has expanded to 100+ buildings of various sizes, uses, and utility consumption/cost. To date, total conditioned square footage is approximately 3,227,000 ft 2. A majority of FY12 utility consumption/cost is associated with buildings in the central core used for administration, library, academic, research, residential, athletic/physical fitness, food service, parking structures, and energy production; and Child Development Center, Activities Center, and the West Campus buildings used for scientific research, warehouse, facilities services/support, and athletic/grounds support. Three newly constructed buildings had a partial effect on FY12 utility cost/consumption Bauerle Road Garage, Sculpture & Ceramic Graduate Studio, and North Paseo Building. Additionally, two projects, currently under construction, consumed some utilities during FY12 --San Saba housing complex, and Plaza Norte Building. ELECTRICITY Electricity is purchased from CPS Energy on two rate structures: Super Large Power (SLP) and General Service (PL). Electric power is fed into a main substation at 13,800 Volts, and stepped down to 480 V/277 V at the building transformer vaults. The SLP rate (currently the lowest electric rate in San Antonio) is applied to all accounts on the Main Campus, with the exception of two. A roadway account and the East Campus Road Lot account are billed at the PL rate. NATURAL GAS Natural Gas is purchased from CPS Energy on two rate structures: Large Volume Gas (LVG) or the General Service Commercial (G). Natural gas is supplied directly to the North Thermal Energy Plant, then split four ways and billed on four separate accounts. Two accounts are for the North Thermal Energy Plant itself one for supply to the engine generator and a second for the boilers. The third account supplies the South Thermal Energy Plant, and a fourth provides service to all other campus buildings (except Chaparral Village and Child Care Center). A separate line supplies the Chaparral Village student housing complex and is divided further to supply Roadrunner Café; the LVG rate is applied to both on a combined account. Another line serves the Child Care Center, with an account billed at the General Service rate. 08 FY12 Narrative - MAIN

17 THE UNIVERSITY OF TEXAS AT SAN ANTONIO WATER Water is supplied by the San Antonio Water System via two water lines (8 and 10 ) that co-mingle. There are two accounts. One account bills for water supplied to all buildings except the Child Care Center. A second account bills for Child Care Center usage, and further tracks the split between irrigation and domestic water usage. THERMAL UTSA has contracted with Win-Sam, Inc. to operate the two UTSA-owned thermal energy plants at the Main Campus North Thermal Energy Plant (NTEP) and South Thermal Energy Plant (STEP). Win-Sam pays a portion of the utilities consumed by the plants thus ensuring efficient production of thermal energy. Approximately 92% of campus natural gas, 39% of all campus water, and 27% of all campus electricity is directed to the two Thermal Energy Plants and is used to produce chilled water and steam/hot water for campus cooling and heating. Seven chillers, with a total cooling capacity of 12,400 tons, are operated primarily with electricity from the local utility. Four boilers (two steam and two heating water), with a total heating capacity of 3,600 HP, are operated exclusively with natural gas. Chilled water is supplied at 39 and returned at 51. Steam is supplied from the North Thermal Energy Plant at either 125 psi/250 psi or at 350 /500 depending on campus heating needs. Heating water is supplied from the South Thermal Energy Plant at 180 and returned at 130.

For purposes of this rate transmission voltage is defined as 138 KV or higher, distribution primary voltage is 13.2 KV up to 69 KV and distribution secondary voltage is less than 13.2 KV. This rate is not applicable (a) when another source of electric energy is used by the Customer or (b) when another source of energy (other than electric) is used for the same purpose or an equivalent purpose as the electric energy furnished directly by CPS Energy, except that such other source of energy as mentioned in (a) and (b) may be used during temporary failure of the CPS Energy electric service. This rate is not applicable to emergency, temporary, or shared service. It is also not applicable to resale service. TYPE OF SERVICE The types of service available under this rate are described in CPS Energy Electric Service Standards. When facilities of adequate capacity and suitable phase and voltage are not adjacent to the premises served or to be served, the required service may be provided pursuant to CPS Energy Rules and Regulations Applying to Retail Electric & Gas Service and the CPS Energy Policy for Electric Line Extensions and Service Installations. CPS Energy will furnish sufficient transformer capacity and other facilities in order to allow maintenance of CPS Energy equipment at the least possible inconvenience to the customer consistent with other system priorities.

31 Effective: March 1, 2010 Page 2 of 3 Minimum Bill The Minimum Bill shall be equal to the Service Availability Charge plus the applicable Demand Charge or such higher Minimum Bill as may be specified in the Customer's Application and Agreement for Electric Service. The Minimum Bill is not subject to reduction by credits allowed under the adjustments below. Adjustments Plus or minus an amount which reflects the difference in the unit fuel cost factor for the current month above or below a basic cost of $ per KWH sold. The unit fuel cost factor for the current month is computed as the sum of: (a) The current month's estimated unit fuel cost per KWH, which is computed based upon the current month's estimated KWH generation mix, unit fuel cost by fuel type, any known changes in fuel cost, sales to other than long-term customers, purchases and line losses; plus (b) An adjustment, if indicated by the current status of the over and under recovery of fuel costs for the recovery year in progress, to correct for the difference between the preceding month's estimated unit fuel cost and the current computation for this value. This adjustment is computed by multiplying the difference between the preceding month's estimated unit fuel cost (corrected for any fuel supplier surcharge) and the current computation for this value times the KWH generated during the preceding month and then dividing the result by the current month's estimated KWH sales; plus (c) An adjustment, if indicated by the current status of the over and under recovery of fuel costs for the recovery year in progress, to correct for the difference between the preceding month's estimated value for the second preceding month's unit fuel cost and actual unit fuel cost for that month. This adjustment is computed by multiplying the difference between the preceding month's estimated value for the second preceding month's unit fuel cost and the actual unit fuel cost for that month (corrected for any fuel supplier surcharge) times the KWH generated during the preceding month and then dividing the result by the current month's estimated KWH sales; plus (d) An adjustment, as necessary, which may be derived and applied to the unit fuel cost factors during the months preceding, including, and/or following January each year, depending on the dollar amount of adjustment necessary to balance the annual cumulative actual fuel cost with the annual cumulative fuel cost recovery through these rates; plus (e) An adjustment to reflect offsetting credits to or additions to fuel costs resulting from judicial orders or settlements of legal proceedings affecting fuel costs or components thereof, including taxes or transportation costs, or to reflect accounting and billing record corrections or other out-of-period adjustments to fuel costs. (f) An adjustment, as necessary, which may be derived and applied to the unit fuel cost factors for recovery of dollars spent for the verifiable kw reductions that are above the level reflected in base rates for energy efficiency and conservation programs. Recovery of such costs would be allowed once an independent third party reviews and confirms the incremental kw reductions. Plus or minus the proportionate part of the increase or decrease in taxes, required payments to governmental entities or for governmental or municipal purposes which may be hereafter assessed, imposed, or otherwise required and which are payable out of or are based upon revenues of the electric system. Monthly Demand The Monthly Demand will be the KW as determined from reading the CPS Energy demand meter for the 15 minute period of the Customer's greatest Demand reading during the month.

This rate is not applicable (a) when another source of electric energy is used by the Customer or (b) when another source of energy (other than electric) is used for the same purpose or an equivalent purpose as the electric energy furnished directly by CPS Energy, except that such other source of energy as mentioned in (a) and (b) may be used during temporary failure of the CPS Energy electric service. This rate is not applicable to emergency, standby, or shared service. It also is not applicable to resale service except that submetering will be permitted under this rate only for the purpose of allocating the monthly bill among the tenants served through a master meter in accordance with CPS Energy Rules and Regulations Applying to Retail Electric & Gas Service. TYPE OF SERVICE The types of service available under this rate are described in CPS Energy Electric Service Standards. When facilities of adequate capacity and suitable phase and voltage are not adjacent to the premises served or to be served, the required service may be provided pursuant to CPS Energy Rules and Regulations Applying to Retail Electric & Gas Service and the CPS Energy Policy for Electric Line Extensions and Service Installations.

Minimum Bill $8.25 plus $3.10 per KW of Billing Demand in excess of 5 KW. A higher Minimum Bill may be specified in the Customer's Application and Agreement for Electric Service. The Minimum Bill is not subject to reduction by credits allowed under the adjustments below. Rev. 03/01/2010 PL

38 Effective: March 1, 2010 Page 2 of 3 Adjustments Plus or minus an amount which reflects the difference in the unit fuel cost factor for the current month above or below a basic cost of $ per KWH sold. The unit fuel cost factor for the current month is computed as the sum of: (a) (b) (c) (d) (e) (f) The current month's estimated unit fuel cost per KWH, which is computed based upon the current month's estimated KWH generation mix, unit fuel cost by fuel type, any known changes in fuel cost, sales to other than long-term customers, purchases and line losses; plus An adjustment, if indicated by the current status of the over and under recovery of fuel costs for the recovery year in progress, to correct for the difference between the preceding month's estimated unit fuel cost and the current computation for this value. This adjustment is computed by multiplying the difference between the preceding month's estimated unit fuel cost (corrected for any fuel supplier surcharge) and the current computation for this value times the KWH generated during the preceding month and then dividing the result by the current month's estimated KWH sales; plus An adjustment, if indicated by the current status of the over and under recovery of fuel costs for the recovery year in progress, to correct for the difference between the preceding month's estimated value for the second preceding month's unit fuel cost and actual unit fuel cost for that month. This adjustment is computed by multiplying the difference between the preceding month's estimated value for the second preceding month's unit fuel cost and the actual unit fuel cost for that month (corrected for any fuel supplier surcharge) times the KWH generated during the preceding month and then dividing the result by the current month's estimated KWH sales; plus An adjustment, as necessary, which may be derived and applied to the unit fuel cost factors during the months preceding, including, and/or following January each year, depending on the dollar amount of adjustment necessary to balance the annual cumulative actual fuel cost with the annual cumulative fuel cost recovery through these rates; plus An adjustment to reflect offsetting credits to or additions to fuel costs resulting from judicial orders or settlements of legal proceedings affecting fuel costs or components thereof, including taxes or transportation costs, or to reflect accounting and billing record corrections or other out-of-period adjustments to fuel costs. An adjustment, as necessary, which may be derived and applied to the unit fuel cost factors for recovery of dollars spent for the verifiable kw reductions that are above the level reflected in base rates for energy efficiency and conservation programs. Recovery of such costs would be allowed once an independent third party reviews and confirms the incremental kw reductions. Plus or minus the proportionate part of the increase or decrease in taxes, required payments to governmental entities or for governmental or municipal purposes which may be hereafter assessed, imposed, or otherwise required and which are payable out of or are based upon revenues of the electric system. Monthly Demand The Demand will be the KW as determined from the reading of the CPS Energy demand meter for the 15 minute period of the Customer's greatest Demand reading during the month. Billing Demand For the period June through September, the Billing Demand is equal to the Monthly Demand as defined above. For the period October through May, the Billing Demand is equal to the Monthly Demand or 80% of the highest measured demand established during the previous summer period months (June through September), whichever is greater. Prior to the establishment of a previous summer peak Demand, the Billing Demand shall be equal to the Monthly Demand as defined above. Power Factor When, based on a test of the Customer's power factor, the power factor is below 85% lagging, the Billing Demand may be increased by adding 1% of the Actual Demand for each 1% that the power factor is below 85%. High Voltage Discount This discount applies only to electric service supplied at CPS Energy nominal distribution voltage of 13.2 KV or higher, when (a) such service voltage requires no more than one (1) step down transformation from transmission voltage of 69 KV or higher, and when (b) such service can be supplied in accordance with CPS Energy distribution system design criteria. For service supplied under this discount, the Energy Charge per KWH for usage up to 200 KWH per KW of Billing Demand will be discounted by $ per KWH. The Customer must be demand metered and must own and maintain at Customer expense all other transformers and facilities that might be required to utilize this service. Rev. 03/01/2010 PL

TYPE OF SERVICE Natural gas will be supplied at a nominal gauge pressure of four ounces per square inch. If natural gas is metered at a pressure higher than four ounces, measurements will be adjusted to the equivalent of four ounces. When mains of adequate capacity and suitable pressure are not adjacent to the premises served or to be served, the required service may be provided pursuant to CPS Energy Rules and Regulations Applying to Retail Electric & Gas Service and the CPS Energy Policy for Gas Main Extensions and Service Installations. MONTHLY BILL Rate $ 8.95 Service Availability Charge $ Per CCF for all CCF 1 CCF equals 100 cubic feet Minimum Bill $8.95. A higher Minimum Bill may be specified in the Customer's Application and Agreement for Gas Service. The Minimum Bill is not subject to reduction by credits allowed under the adjustments below. Adjustments Plus or minus an amount which reflects the difference in the unit gas cost factor for the current month above or below a basic cost of $0.220 per CCF sold. The unit gas cost factor for the current month is computed as the sum of: (a) The current month's estimated unit gas cost per CCF, which is computed based upon the current month's estimated CCF purchases, unit gas cost by supplier, any known changes in gas cost, and pipeline losses; plus (b) An adjustment, if indicated by the current status of the over and under recovery of gas costs for the recovery year in progress, to correct for the difference between the preceding month's estimated unit gas cost and the current computation for this value. This adjustment is computed by multiplying the difference between the preceding month's estimated unit gas cost (corrected for any gas supplier surcharge) and the current computation for this value times the CCF purchased during the preceding month and then dividing the result by the current month's estimated CCF sales; plus (c) An adjustment, if indicated by the current status of the over and under recovery of gas costs for the recovery year in progress, to correct for the difference between the preceding month's estimated value for the second preceding month's unit gas cost and actual unit gas cost for that month.

A more detailed approach is necessary to compute the total cost of cooling in $/t-h and heating in $/mmbtu. The current contractural agreement between UTSA and Win-Sam stipulates that Win-Sam will credit a portion of the electricity, natural gas, water, and diesel used by the plants. The calculation used to arrive at the actual cost of heating and cooling is not part of this report. However, the calculated cost for thermal energy is supplied as part of this narrative. For simplicity, all electrical costs are attributed to cooling and all boiler natural gas costs are attributed to heating. Water and the fixed demand charge by Win-Sam to operate the plant are more difficult to allocate. To best allocate water and demand costs, the total heating and cooling energy is divided by the total energy produced to arrive at an estimated percent of heating and cooling. In 2012, 78% of the total thermal energy was for cooling and 22% for heating. Thus, 78% of the water and demand costs were attributed to cooling and 22% to heating. The 2012 cost of chilled water is thus $0.086/t-h and the cost for steam/hot water is $13.62/mmbtu Calculated CHW & Steam/Hot Water Rates CHW $0.086/T-H STM $13.62/MMTBU 69 FY12 WINSAM Energy Plant Summary
