This repository contains all model development using GENESYS_MOD within the open_MODEX project.

What is GENeSYS-MOD?

##How to run GENeSYS-MOD

Install GAMS

1. Choose the GAMS version depending on your system: https://www.gams.com/download/
2. Follow the steps of installation wizard.

Note: A GAMS licens is required.

Set up a framework environment

1. Create a directory with the project name in any convenient location.
2. Download the model from GitHub by either:
   • cloning the GENeSYS-MOD GitHub repository, or
   • downloading the zip file and extracting all to the previously created project directory.

Open a model in GAMS

1. Open the main folder (either for single year scenarios or pathway) and create a new text file:
   • name it e.g. as the scenario and
   • change the file extension from txt to gpr (GAMS project file).
2. Open the .gpr file: This will start the GAMS IDE.
3. After the GAMS startup open the genesysmod.gms file.

Run the model

Run the model by simply pressing F9.

Access results

There are many options, here are two:

1. The open_MODEX result files are placed in the model folder under:
   • /results/MODEX/.

Scenario data

1. Depending on which scenario should be calculated, either the folder Single Year Scenarios or Scenario Variation Pathways needs to be used.
2. If Single Year Scenarios is chosen, the user has the possibility to chose between 9 different scenarios. To do so, two options need to be set depending on the scenario:
   • The year needs to be set to the year of interest at the top of the genesysmod.gms file.
   • Also in the genesysmod.gms file, the scenario needs to be set to the desired one.
3. The different scenarios and specifications for the two options are as following:
   • Baseyear 2016 (year: 2016, Scenario: Base)
   • Baseyear 2030 (year: 2030, Scenario: Base)
   • Baseyear 2050 (year: 2050, Scenario: Base)
   • Scenario Variation Renewable Target (year: 2030, Scenario: RETarget)
   • Scenario Variation Increased Demand (year: 2030, Scenario: HighDemand)
   • Scenario Variation Early Coal Phase-out (year: 2030, Scenario: NoCoal)
   • Scenario Variation Combination of previous three (year: 2030, Scenario: All3)
   • Scenario Variation Reduced Emission Budget (year: 2030, Scenario: LowEmissions)
   • Scenario Variation Increased Emission Budged (year: 2030, Scenario: HighEmissions)
