20. Quick Overview Jay Zarnikau Frontier Associates LLC 20

21. Background and Introduction  Texas Senate Bill 7 requires distribution utilities in Texas to meet 107 of their load growth by offering and administering energy efficiency programs.  Each of the States affected distribution utilities offer a Large Commercial and Industrial Standard Offer Program to help satisfy this goal.  The legislation requires incentive programs to be market neutral and non-discriminatory, so the C&I Standard Offer Program is available to all of the utilities distribution customers on a “first come, first served” basis. 21

22. Standard Offer Program  Program administrator (electric utility) offers set incentive payment to participants for each kWh or kW saved through installation and operation of an energy efficiency measure.  Program administrator signs a standard contract with participants outlining their responsibilities under the program.  Applications considered on per-project basis; first- come, first-served.  Number of participants limited only by available incentive dollars.  Project Sponsor and customer determines efficiency measures to be installed—program measure/technology neutral.

42. Measurement and Verification Mike Stockard 42

43.  Measure-specific M&V guidelines  Stipulated values for data such as operating hours, fixture wattages and equipment efficiencies  Pre-derived savings calculations for some measures  Minimize project sponsor M&V costs and utility administration, while producing justifiable energy savings Streamlined M&V Procedures 43

44.  Appropriate M&V Approach depends mainly on: –Type of retrofit and equipment –Operational predictability –Project complexity  Main categories of M&V for C&I program: –Deemed savings (in select applications) –Simplified M&V methods –Full M&V methods –Alternate M&V methods may be proposed by Sponsor, but must adhere to IPMVP and be approved by Utility C&I Program M&V 44

45. Simplified Lighting Example  Typical Small Office Building  Sponsor submits full lighting survey, detailing existing and proposed fixtures  3,760 stipulated operating hours for office buildings  80% coincidence factor for office buildings 45

46.  Savings Calculations  Lighting Demand Savings: 38.6 kW – 18.7 kW = 19.9 kW  Interactive Demand Savings: 19.9 kW * 0.10 = 2.0 kW Total Demand Savings: (19.9 kW + 2.0 kW) * 0.80 = 17.7 kW  Lighting Energy Savings: 19.9 kW * 3,760 hrs = 74,824 kWh  Interactive Energy Savings: 74,824 kWh * 0.05 = 3,741 kWh Total Demand Savings: 74,824 kWh + 3,741 kWh = 78,565 kWh Simplified Lighting Example (cont.) 46

47.  Chiller Replacement in Office Building Retrofit Description:1-for-1 300 Ton Water-Cooled Centrifugal Chiller Replacement Existing Chiller Efficiency:COP=5.0 (0.70 kW/ton) New Chiller Efficiency:COP=6.6 (0.53 kW/ton) Baseline Chiller Efficiency (ASHRAE 90.1-1989): COP=5.2 (0.68 kW/ton) Spot kW measurement of existing chiller at peak conditions: 135 kW 12-months post-retrofit measured chiller kWh: 334,200 kWh Simplified Cooling Example 47

48.  Savings Calculations Simplified Cooling Example (cont.) 48

49.  Baseline must account for minimum state and federal standards  Standard forms must be used  M&V reports must be complete and properly documented before any payments will be made  “Service quality” must be maintained  For example - lighting levels  Metering  Calibration required  All collected data must be submitted with reports  Must be adequate to capture full range of operating conditions General M&V Rules 49

50. Example Incentive Calculations Karen Radosevich 50

51. Pricing for programs is based on a cost effectiveness standard  Based on avoided cost of a new gas turbine: –$400 per kW capacity –2.5 cents per kWh off-peak energy  Incentives for large commercial and industrial projects can be up to 35% of avoided cost.  Incentives vary by utility: –$150 to $200 per kW reduction –5.0 to 6.9 cents per annual kWh saved  Lighting Cap -- kW and kWh savings derived from lighting measures are capped at 65% of the total savings.  Load Factor Cap -- Utilities may place a limit on the ratio of kWh payment to kW payment. 51

52. Example 1 - Simple Calculation A commercial HVAC project saves 25 kW of summer peak demand and 50,000 annual kWh. 25 kW x $175/kW + 50,000 kWh x $0.06/kWh = $7,375 52

53. Example 2 -- Load Factor Cap An industrial variable-speed motor retrofit saves 20 kW of summer peak demand and 150,000 annual kWh. The unadjusted incentive payment for this project would be: (20 x$175) + (150,000 x $0.06) = $12,500 The utility is utilizing a load factor cap that limits combined kW and kWh payment to $600 per kW. 20 x $600 = $12,000 This project would be subject to the load factor cap. Incentive would not exceed $12,000. 53

54. Example 3 - Lighting Cap A commercial office project saves 15 kW and 60,000 kWh from lighting measures and 4 kW and 8,000 from HVAC. % of kW savings from lighting = 15/19 = 79% % of kWh savings from lighting = 60,000/68,000=88% Adjusted kW = (19 x 0.65) + 4 = 16.35 kW Adjusted kWh = (68,000 x 0.65) + 8,000 = 52,200 kWh (16.35 x $175) + (52,200 x $0.06) = $5,993 54

55. In conclusion…  A new generation of energy efficiency programs are up and running.  For energy services companies, equipment distributors and manufacturers, installers of energy-efficient equipment, and others, these programs provide new business opportunities.  The state’s utilities and the PUCT are counting on your ideas and efforts to help ensure that we meet our goal for energy efficiency! 55
