Link to LEAP

The Link to LEAP screen is used to set up a live connection between a WEAP water resource planning model and a LEAP energy planning model.

The Long-range Energy Alternatives Planning System (LEAP) is SEI's software tool for energy policy analysis and climate change mitigation assessment.  LEAP has been adopted by hundreds of organizations in more than 150 countries worldwide.  Its users include government agencies, academics, non-governmental organizations, consulting companies, and energy utilities. It has been used at many different scales ranging from cities and states to national, regional and global applications.  LEAP is an integrated modeling tool that can be used to track energy consumption, production and resource extraction in all sectors of an economy.  It can be used to account for both energy sector and non-energy sector greenhouse gas (GHG) emission sources and sinks.  In addition to tracking GHGs, LEAP can also be used to analyze emissions of local and regional air pollutants, making it well-suited to studies of the climate co-benefits of local air pollution reduction.

WEAP and LEAP are sister tools that share the many of the same design features and approaches and which are created by software teams that closely collaborate with each other. In particular WEAP and LEAP share the following features:

Use the Advanced: LEAP Link screen in WEAP (or the parallel Link to WEAP screen in LEAP) to establish a connection between a WEAP area and a LEAP area.  Once a WEAP area is linked to a LEAP area, you can use the LEAPValue function in expressions to read data and results from LEAP.

Bear in mind that this option is only available if both WEAP and LEAP are installed and registered on your computer.

To set up a link between two areas, first check the Link to LEAP Model check box, then select a LEAP area from the selection box. Once you have done this the configuration data describing the LEAP area will be read by WEAP and you will then be asked to specify how the various elements in the WEAP and LEAP areas are mapped to one another. In particular, use the table that is displayed in the form to specify mappings between WEAP and LEAP scenarios, and between WEAP and LEAP timesteps.

Any errors or missing mapping are displayed on screen in red. You can also click the Error Check button to have WEAP and LEAP check for any problems in the WEAP-LEAP linkage.

Four major restrictions apply to the WEAP areas that can be linked to LEAP.

  1. Both areas must have the same base and end years.

  2. LEAP areas must have only a single year of data in their Current Accounts data.

  3. LEAP areas must have only a single region.

  4. WEAP and LEAP must have an exactly matching set of timesteps (typically both should be monthly).
