2004 ACEEE Summer Study on Energy Efficiency in Buildings2004 ACEEE Informal Sessions DescriptionsAdditional Informal Sessions may be organized on-site during the Summer Study. Visit the office in Surf and Sand to sign up for an Informal Session. Session Synopsis - "Energy Savings Accounting – Today's Business Requirements" Dennis J. Nelson, BC Hydro
Monday, August 23 Utility information and planning needs are much more complex now than they were in the 1990s, and BC Hydro's Power Smart group has been working through these internal reporting challenges for the last four years. The introduction to this session (and an accompanying background paper) suggest approaches for reporting (and more importantly forecasting) energy savings so that all stakeholders, both inside and outside the organization, can understand and use the information. Concepts of run rate vs. acquired energy; energy vs. demand savings; gross vs. net savings; system losses adjustments; timeframes and forecast views; and two types of savings persistence will be discussed. With common and understood energy accounting practices, benchmarking between utilities would be feasible. EIA terminology and the associated reporting challenges will be addressed. The goal is to provide a context for the discussion, have attendees describe their tracking/reporting environments, and then determine what participants' utilities/agencies are doing to improve the usability of energy savings forecasts. For participants who are interested, a separate but closely related session on benchmarking, is planned for the Tuesday afternoon. For more information, contact: Dennis J. Nelson |
