How The Power Coverage Simulators Work And Are Developed


By Robbie Orvis

The free and open-source Power Coverage Simulator (EPS) pc mannequin developed by Power Innovation Coverage & Know-how LLCTM has change into one of the vital broadly used instruments to tell policymakers and regulators about which local weather and vitality insurance policies will cut back greenhouse gasoline emissions most successfully, creating the most important financial and public well being advantages.

With EPS fashions now utilized in 10 nations and 48 states throughout America, we’re typically requested how the EPS works and what peer evaluation it has undergone by its growth.

The EPS is a System Dynamics pc mannequin created in Vensim, a device produced by Ventana Methods for the creation and simulation of System Dynamics fashions. The mannequin is designed for use with the free Vensim Mannequin Reader, and instructions on acquiring Vensim Mannequin Reader and the EPS can be found on the Obtain and Set up web page. As an open-source modeling device, customers can entry the mannequin through the energypolicy.options web site. To make use of superior options or modify its enter knowledge, customers could obtain the EPS and run it regionally on their Mac or Home windows PC. All the enter knowledge is meticulously cited, publicly accessible, and freely accessible and editable, with outcomes up to date immediately.

The EPS permits customers to mannequin quite a few insurance policies that have an effect on vitality use and emissions together with a renewable portfolio commonplace, gasoline economic system requirements for automobiles, trade methane requirements, incentives for clear vitality applied sciences like we see within the Inflation Discount Act, and accelerated R&D development of varied applied sciences. These insurance policies might be utilized throughout each main sector of the economic system together with transportation, electrical energy provide, buildings, trade, agriculture, and land use. The EPS additionally contains smaller parts like hydrogen provide, district warmth, waste administration, and geoengineering.

The mannequin stories outputs at annual intervals and gives quite a few outputs, together with:

  • Emissions of 12 completely different pollution together with carbon dioxide, nitrogen oxides, sulfur oxides, and positive particulate matter, in addition to carbon dioxide equal (CO2e) which measures the worldwide warming potential of varied pollution.
  • Direct money circulate (value or financial savings) impacts on authorities, non-energy industries, labor and shoppers, and 5 energy-supplying industries.
  • Direct, oblique, and induced impacts on jobs, GDP, and worker compensation, as an entire or disaggregated into 36 financial classes.
  • Untimely mortality and 10 different health-related outcomes prevented from diminished main and secondary particulate air pollution.
  • The composition and output of the electrical energy sector (e.g., capability and era from coal, pure gasoline, wind, photo voltaic, and so forth.).
  • Car know-how market shares and fleet composition together with electrical automobiles.
  • Power use by gasoline sort from numerous energy-using applied sciences together with particular varieties of automobiles and constructing parts.
  • Breakdowns of how every coverage inside a coverage package deal contributes to whole abatement and the cost-effectiveness of every coverage (e.g., wedge diagrams and price curves).
  • Gas imports and exports, and related expenditures or revenues.

All methodologies underpinning the EPS have undergone in depth peer evaluation as they have been developed, and we frequently search enter from exterior specialists to switch the methodologies to handle any considerations which might be raised. Elements of the mannequin have been reviewed by people from prestigious establishments together with:

  • American Council for an Power-Environment friendly Financial system
  • Argonne Nationwide Laboratory
  • Lawrence Berkeley Nationwide Laboratory
  • Massachusetts Institute of Know-how
  • Nationwide Renewable Power Laboratory
  • RMI
  • Stanford College
  • Tufts College
  • College of Chicago
  • U.S. Environmental Safety Company
  • World Sources Institute
