Overview Current status of Commercial EM Commercial programs overview EM TAG ambitions

Energy Management and Commercial Significant opportunity in 6th Power Plan Expanding commercial portfolio Current status: limited Custom projects Existing building commissioning-like projects First, why do we care: There is significant opportunity in existing building commissioning in commercial buildings in the 6th Power Plan As codes and standards increase, opportunities for widget-based measures are diminishing Know there is opportunity and our industrial program has had some success as have other programs in the NW region and across the country What is currently being done in energy management? A very small number of projects are being done as custom projects – typically in large buildings such as hospitals or universities. RFP on the streets to our utility customers for behavior based programs in residential and commercial

Commercial Programs Overview Deemed Measures Calculated Measures Custom Projects Refrigeration Lighting Calculator New Construction HVAC Additional Refrigeration All Other Retrofits Insulation & Windows Kitchen & Food Service Basic overview of how our programs are implemented: we develop the measures and program offerings, the utility decides if and how to implement them. Utility manages its own budget for incentives. Currently, the biggest sources of savings are lighting and grocery refrigeration (EnergySmart Grocer program) HVAC measures: Unitary AC DHP in limited applications WEPT in modular classrooms Additional measures: Network computer power management Smart power strips Commercial showerheads Electric storage water heaters Additional measures

EM TAG Ambitions Focus on products/technologies Overcome current hurdles Claiming savings Extending measure life beyond 1 year Reducing implementation costs Achieve RTF approval Current hurdles: Claiming savings: for example, industrial relies on regression analysis and tracking tools to verify savings Extending measure life: for purposes of claiming savings against the power plan, is important to have a measure life longer than one year. Looking for technologies with persistence elements and persistence assurance. Reducing implementation costs: with limited budgets, is not always possible to launch large-scale program like EnergySmart Industrial. Need technologies that can be implemented with relatively low implementation costs Relative simplicity: some customers have the luxury of multiple staff to manage efficiencies, others have 1-2 staff people doing everything in efficiency. Others have even less staff time. Our approaches need to be require relatively low participation from the customer utility to implement. Achieve RTF approval: best way to book savings is through RTF approved measures and methodologies. Approaches may go Custom initially, but far greater efficiencies can be gained through RTF approval.

EM Technology Ambitions Addresses a diverse group of building types Serves small commercial buildings Relevant across the NW region Needs: Address a diverse group of building types to be applicable to a broad range of applications. Or addresses a building type that everyone has in their territory – small office, hospitality, schools Serves small commercial: lots of small commercial, poses a big challenge in energy management, but we know there is opportunity. Relevant to many of BPA’s customer utilities – while any given solution won’t be applicable to all shapes and sizes, need to try to maximize relevance and value. I.e. don’t want only measures that work in large urban buildings.
