3. Why We Do What We Do …after a series of ridiculously expensive power industry missteps, Congress set the PNW on a course that established treating energy efficiency as a resource in power planning – just like generation 3

4. Pacific Northwest Region The 1980 Regional Power Act 4

5. slide 5 Major Elements of the Northwest Power and Conservation Act of 1980  Authorized States to form Council  Directed Council to develop 20-year load forecast and resource plan (“The Plan”)  Bonneville is given authority to acquire resources consistent with the Council’s Plan  Plan is to provide for the development of the least cost mix of resources  Conservation is defined as resource equivalent to generation and given a 10% cost advantage  Mandated public involvement in planning process.

37. Conservation Can Provide Capacity Benefits Depending on WHEN a measure saves energy 37

38. What Does 7P Suggest for EE Programs & Evaluators & Engineers ?  Steady as she goes  Lots of low-cost potential & challenges to acquire it  Spot market price is NOT the avoided cost for least-cost  Expand thinking beyond annual energy savings to kW  Need hourly savings profiles  Integration with DR programs  Baselines changing – programs adjust  Be smart & strategic about programs  Importance of EE research & performance 38

39. 39 7P: New EE Goals & New Baselines

40. But What If We Don’t Need Energy or Capacity Today? Plan Findings 40  Underlying load growth  Loss of existing generation  A steady EE build - 0ffsetting long- term net growth is least-cost and low-risk  Incremental sustained progress at low cost accumulates high value

41. Lots of EE Between Spot Market Price & Cost of New Generation 41 Spot Market Gas CCCT

42. Spot Market Price Is Not The Least-Cost Avoided Cost For EE Plan Findings  Building about twice the EE than would be built with spot market as avoided cost  And reduces long-term system cost & risk & revenue requirements 42 System costs and risk both increase by about 15 percent if spot market price is used as avoided cost

43.  About 30 new measures  Nearly half of potential  Key new technology  SSL & Controls ~50%  HVAC ~25%  Electronics ~15%  Plug loads  Behavioral  New applications of old 43 And There Are New Measures

44. Incorporate Value of Deferred Generation Capacity in B/C  Energy  Deferred Capacity  Avoided Annual O&M  Avoided Other fuel  Non-Electric Benefit  Avoided Periodic Replacement  Risk Avoidance  Capital  Program Admin  Annual O&M  Other fuel  Non-Electric Cost  Periodic Replacement Benefits Costs 44

45. What Does Revised Cost-Effectiveness Mean?  Will credit more value to measures that provide peak capacity reduction  And less to those that don’t 45

75. Embedded Data Center Savings 261 aMW 75

76. What is VRF?  Variable Refrigerant Flow (VRF) Systems  One outdoor unit connects to multiple indoor units through refrigerant lines  VRF systems can adjust heating and cooling outputs by adjusting the refrigerant flow and variable speed compressor  Separate ventilation system (e.g., DOAS)  Energy savings from:  Part load efficiency  Eliminated duct losses  Reduced simultaneous heating/cooling  Better ventilation control  Heat recovery  Optimized building design (new construction) VRF 76

77. Variable Refrigerant Flow  Applies to new buildings and some major retrofits  Potential: 80 aMW over 20 years  Only 6 aMW by 2021 (sl0w ramp)  Significant part of savings is from DOAS  Needs further research and demonstration in PNW 77

78. Advanced Rooftop Controller  Advanced Rooftop Controller (ARC) – a controller applied to single zone rooftop systems with constant speed fans  Some commercial buildings are over-ventilated  Constant speed fans are set to run when the building is occupied  The controller modulates the supply fan to reduce energy consumption 78

79. Advanced Rooftop Controller (ARC) Retrofit: Field-Test Results  The ARC measure is based primarily on the ARC Retrofit study conducted by Pacific Northwest National Laboratory.  Study completed in 2013 79

80. ARC Savings Components  There are four primary components to the ARC savings:  Supply Fan Speed Controls (significant portion of total savings)  Integrated Air-side Economizer Controls  Cooling Capacity Controls  Simple on/off, and staged cooling  Demand-Controlled Ventilation Controls  Return-air CO2  Cost effective potential includes:  22 aMW by 2021  84 aMW by 2026  119 aMW by 2035 80

81. HVAC Energy Management  Measures for commercial buildings, excluding single-zone ducted systems  Focused on making HVAC systems work better mostly through controls changes, operations & commissioning 81

82. EM Measure Assumptions  Savings= 18.5% of heating energy for electric heated buildings and 15% for gas heated buildings  Compared the savings values with some limited data from ETO on commercial SEM. For office buildings, the data show about 7% total EUI savings. This translates to approximately 18% electric heating EUI savings; very similar to the 6P assumption.  Baseline adjustments were made to reflect the reduced EUI's in the 2013 CBSA compared with the 2009 CBSA  Sources: program data from LBL, PECI, NEEA, SMUD  For retro Cx, savings range 1 to 2.2 kWh/sf from these programs. Savings range 0.5 to 1.2 kWh/sf for New.  Significant achievements between 2010 and 2015  Saturation is 19% per 6 going on 7 data for "Energy Management Systems/System Controls" category  Reduced the lifetime to 5 years (7 years in the 6P) 82

83. EM Potential  EM potential  44 aMW by 2021  62 aMW by 2026  69 aMW by 2035  Represents four percent of commercial 2035 potential 83

90. Summing Up 90

91. Since 1978 Utility Funded Programs and Codes and Standards have Produced Nearly 5800 aMW of Savings 91

92. What’s the Value of 5800 aMW?  It’s represents enough energy savings to save the region’s electricity consumers nearly $3.73 billion in 2014  It lowered carbon emissions in the Pacific Northwest by an estimated 22.2 million MTE 92

93. Energy Efficiency Was The Region’s Second Largest Resource in 2014 Based on 2014 Actual Dispatch and Hydro Resource Output from EIA 93
