2 TDV Value Overview Estimates of long-run marginal cost of electricity supply Computed for 8 cities across US climate zones for use in air conditioner appliance standards Cities selected based on range of climates and air conditioner market size Correlated to TMY3 weather data, and an assumed weekday / weekend and holiday day-order of 1991 Methodology similar to California Title 24 TDV values introduced in 2005 Title 24 Update Only publicly available data was used Non-proprietary spreadsheet formulation and documentation available on the web

3 Climate Zones and Cities Atlanta, GA Chicago, IL Washington DC Fresno, CA Houston, TX New York, NY Phoenix, AZ St. Louis, MO

4 Components of TDV Value ComponentDescription Energy Estimate of hourly wholesale value of energy measured at the point of wholesale energy transaction Losses Losses between the appliance location and the point of wholesale energy transaction Ancillary Services (A/S) The costs of providing system operations and reserves for electricity grid reliability System Capacity The costs of building new generation capacity to meet system peak loads T&D Capacity The costs of expanding transmission and distribution capacity to meet peak loads Environment The costs of SOx, NOx, PM10, and CO2 associated with electricity production
