IRENA FlexTool is an energy systems optimisation model developed for power and energy systems with high shares of wind and solar power. It can be used to find cost-effective sources of flexibility across the energy system to mitigate the increasing variability arising from the power systems. It can perform multi-year capacity expansion as well as unit commitment and economic dispatch in a user-defined sequence of solves. The aim has been to make it fast to learn and easy to use while including lot of functionality especially in the time scales relevant for investment planning and operational scheduling of energy systems.
Documentation structure
- You can find the installation instructions for IRENA FlexTool using Spine Toolbox as its interface (recommended in most cases): Install with Toolbox
- Follow video tutorial for installation with Spine Toolbox here: Link to YouTube

Monthly user support telcos
The monthly user support telco is held on the last Monday of each month at 12-13 UTC (skipping December and July). (Notice that time is according to UTC and in places where day-light saving time is applied, the time of the meeting may change between winter/summer) Each 1 h session starts with a ~15 min presentation on simple IRENA FlexTool demos or tutorials, followed by 45 min Q&A session.
Please contact anni.niemi@vtt.fi for an Outlook calendar invitation.
Recordings and presentations of the past support calls can be found from here.
Background for the FlexTool modelling approach
The theory slides below give some background how FlexTool is formulated. There are also examples that show some ways how FlexTool can be used (including examples from other similar models). The slides were made for training in the OASES project (funded by LEAP-RE, project no: 963530, co-funding from European Commission and national funding agencies). The files can also be found in the folder docs/theory_slides.
