Using the State Energy Policy Simulator to Support Climate Pollution Reduction Grant Planning

The Energy Policy Simulator (EPS) is a free, open-source tool developed by RMI and Energy Innovation to model the environmental, economic, and health impacts of energy policies across the lower 48 US states. The tool supports the Climate Pollution Reduction Grant (CPRG) program by enabling states to calculate GHG inventories, project emissions through 2050, build scenarios to meet reduction targets, and quantify the co-benefits of mitigation measures, such as public health improvements and economic development.

• The Energy Policy Simulator (EPS) is an open-source model that allows non-technical users to estimate the impacts of climate and energy policies on human health, the economy, and the environment via a web interface. It covers sectors including transportation, electricity, buildings, industry, agriculture, and land use, as well as components like hydrogen supply and geoengineering.
• RMI and Energy Innovation have created EPS models for all lower 48 US states using data from federal and state sources, including the Department of Energy and the EPA. State governments in Colorado, Louisiana, Minnesota, New Mexico, and Rhode Island have utilized the EPS for climate action planning.
• The EPS provides comprehensive outputs, including emissions for 12 different pollutants (such as CO2, NOx, and SOx), direct cash flow impacts on government and consumers, GDP and job impacts across 36 economic categories, and health outcomes like avoided premature mortality.
• The EPS can be used to fulfill specific requirements of the CPRG's Priority Climate Action Plans (PCAP), Comprehensive Climate Action Plan (CCAP), and Status Reports. Specifically, it can calculate GHG inventories, project state emissions through 2050, build bottom-up scenarios to hit reduction targets, and quantify the impact of various GHG mitigation measures.
