National Time-Dependent Value (TDV) Overview for Electricity Supply Costs

This document provides a comprehensive overview of the long-run marginal costs of electricity supply, calculated for eight cities across diverse climate zones in the U.S. The analysis supports air conditioner appliance standards and utilizes TMY3 weather data, acknowledging various climatic and market factors. The methodology aligns with the California Title 24 TDV values revised in 2005, ensuring transparency and non-proprietary data availability.
