High Voltage, High Rewards Transmission
The document outlines a framework for evaluating the economic impact of transmission infrastructure, focusing on three primary benefit categories: congestion relief, resource adequacy, and public policy savings. It describes the specific calculations used for these benefits, the financial models applied to different ownership structures (investor-owned, public power, and merchant developers), and compares the results against original project projections for three specific case studies. The authors acknowledge several conservatisms in their approach, including the exclusion of certain benefit categories and the use of isolated line capacity estimates rather than complex power flow simulations.

Appendix: State Electric Vehicle Benefits Methodology, Assumptions, and References
The document outlines the technical framework for assessing electric vehicle (EV) benefits, utilizing EPA eGRID data for power plant emissions and the GREET model for upstream feedstock emissions. It specifies the use of a sales-weighted EV efficiency of 0.314 kWh/mile and an average annual mileage of 11,599 miles. Public health benefits are derived from the American Lung Association's use of the EPA COBRA model, while economic data includes announced manufacturing jobs from the EV Jobs Hub and charging infrastructure growth from the Alternative Fuels Data Center. Fuel cost comparisons rely on NREL utility rates and GasBuddy gasoline prices.

Countdown to Shutdown
The document details the use of the RESOLVE model and the Clean System Power Calculator to evaluate seven scenarios regarding the retirement of the Diablo Canyon nuclear power plant. It focuses on three global warming emissions targets (46 MMT, 38 MMT, and 30 MMT) by 2030 and compares the effects of a 2025 shutdown versus a 20-year extension to 2045. The analysis specifically aims to estimate the resources needed to replace nuclear capacity without increasing emissions and to calculate the resulting differences in nitrogen oxides (NOx) emissions.
