eps-4.0.3-us

4.0.3 - December 12, 2024

• New Features
  • Addition of a new industrial feedstock shifting policy lever
  • New improved tracking of dedicated clean power plants built for green hydrogen production
  • New policy lever for non-BAU zero-emission vehicle requirements at the subregional level (e.g. at the US state level)
  • Addition of new structure to support the breaking out of power plants' own use of electricity
  • Grid storage is now integrated with the capacity additions mechanism
  • New control lever for how to integrate capacity market revenue into cash flows
  • Addition of a minimum distributed solar capacity lever
  • New policy lever to ban CCS retrofits by power plant type
  • Addition of a smoothing time to smooth power plant decommissioning costs
  • Replace thermochemical water splitting hydrogen production pathway with partial oxidation of hydrocarbons option
  • Improves the representation of electricity cash flows, for example smoothing energy market revenues and wholesale energy market costs and combining least-cost and guaranteed dispatch into a single energy market
• Bug Fixes
  • Correct error in process emissions abatement potential for oil and gas CH4
  • Correct double counting of a portion of emissions from hydrogen production
  • Corrects bugs in the calculation of incremental capacity and dispatch from the clean electricity standard policy
  • Correct how the percentage fuel use reductions for electricity are applied to the industrial electrification policy lever
  • Add missing MAX function to two different variables to prevent mismatches between policy and BAU versions of EPS outputs
  • Move emissions from ethanol production from the chemicals subsector into refining
  • Prevent least cost dispatch from being negative in certain cases
  • Allows the ZEV standard to now be applied to non-road vehicle types
  • Fixes to revenue and deployment calculations for hybrid power plants
• Data updates
  • Update historical process emissions data based on EPA's Greenhouse Gas Inventory 1990-2022
  • Update pollutant emissions intensities to use the latest EPA National Emissions Inventory for non-GHGs and EPA GHG Inventory data for N2O emissions from mobile combustion
  • Update hydrogen prices for the electricity sector to assume blue hydrogen
  • Update short-term natural gas prices to use latest gas futures estimates
  • No longer estimate the portion of buildings sector fuel demand used for district heating and instead represent all fuel use and emissions within the buildings sector
