Energy Storage Pathways to Meet California’s 2030 Greenhouse Gas Goals
Abstract
In California, due to solar resources coming online during the day, renewable generation
often exceeds demand, leading to curtailment. However, during peak evening hours,
California is forced to rely on GHG emitting thermal power plants. This will make
it difficult for the state to meet its aggressive GHG reduction target of 40% below
1990 levels by 2030. AB 1405 and SB 338 are two proposed bills that call for a clean
peak standard, where utilities are required to meet a certain percentage of peak hour
electricity from clean resources. The purpose of this study is to evaluate the use
of utility scale battery storage to achieve the clean peak standard, and aid California's
GHG reduction efforts. The study estimated electricity demand and generation profile
in 2030, and used an Excel-based optimization model to determine an ideal storage
capacity and dispatch strategy. Finally, it investigated the total energy storage
cost requirements for different scenarios.
