Newsletter winter 2023 – An inspiring visit to NY

During the past half year we have developed new features for the TIMES model framework, dived into PtX and biogas, and begun the development of a new clean model structure.

Inspired by community

The ETSAP meetup for TIMES-modellers in New York was a great inspiration. During the conference we learn of a UN-database that contains data for all countries of the world. So our new dream is to use the database to automate the model creation and build TIMES-models for all countries in the world.

Read more about the vision in the full newsletter below.

Maabjerg Bioenergy in Holstebro, Denmark.
New biogas-module

Biogas will play an increasing role in the Danish energy system. Therefore we have developed a new biogas module for the Danish Energy Agency, to ensure a detailed representation of biogas in their future mode work.

Read more about the new biogas module right here.

To analyse the demand and supply of green hydrogen and other synthetic fuels, we have developed a new model of Northern Europe.

The model is a combined TIMES-model that includes Denmark, Sweden, Norway, Germany, and Poland. The model also includes external trade-links to UK, Belgium, and the Netherlands.

We hope to publish some results from the analysis soon.

IEA-ETSAP Newsletter Spring 2022

In this ETSAP Newsletter Spring 2022, we share the activities that we have carried out as an active member of the modelling community. As part of the ETSAP community, Energy Modelling Lab is developing the TIMES model framework, using it for a range of projects, and sharing our experiences within the network.


Energy Modelling Lab has worked on models for countries around the world.

In the Nordic countries, we have both investigated paths to a climate-neutral future and dived into the shipping industry, to investigate which fuels will power the future sea transport.

In Vietnam, we have supported the local modelling team, and in Azerbaijan, we have built a full-country model from scratch, facilitated workshops with the key stakeholders with the key stakeholder in energy planning in the country, and trained local modelers to run the model.

New features in TIMES-DK

Inspired by the discussions at the ETSAP meeting in Oslo 2021, we have added energy storage in TIMES-DK.

Additionally, we have added different ancillary services to the model, such as balancing the electricity grid when the demand is greater than the supply.

Giving back to the community

We are always happy to participate in the ETSAP-community activities. After a long period of webinars, it was a relief to join the biannual ETSAP meeting in Oslo in November 2021.

Over the past year, we have also expanded the modelling community by training two new employees in the TIMES-model framework. Other than that we have supported a bachelor student from the University of Southern Denmark in a project on energy islands, three students from the Technical University of Denmark in a project on German hydrogen demand, and a Swedish PhD student on a new model of Gothenburg.

The community is growing, one modeler at a time.

EML activities in the IEA ETSAP community

Time frame: Late 2019 to spring 2021

EML: Energy Modelling Lab ApS –

IEA (Interational Energy Agency) Technology Collaboration Programme ETSAP (Energy Technology Systems Analysis Program) –

EML is an active member of the ETSAP community. EML has and continues to contribute to the ETSAP community in 2020 and 2021. We continue the Danish collaboration and participation at the IEA-ETSAP, Annex X to XIV under the new Annex XV. Our partners and consultants are actively developing TIMES models in several projects, regularly attend ETSAP’s biannual workshops and webinars, took VEDA-TIMES trainings, were and will continue teaching energy systems analysis courses at post-graduate level by deploying the TIMES framework, develop auxiliary tools to improve pre- and post processing tasks and succefully migrated from VEDA1 to VEDA2 during ongoing projects.


NCES2020 Nordic Clean Energy Scenarios 2020ON-TIMES2020

Energiforsk, NMBU, EA, VTT, IVLThe work builds on the NETP projects by complementing the cost-effective pathways with deeper analysis of uncertainty and alternative socio-technical framework conditions. This includes policy, technology shifts, economic outlook, developments in other countries and other societal changes that have an impact on the Nordic region – DK, FI ,IS ,NO and – under construction!
UEOR2021 Energy Outlook Report for UkrainTIMES-UA2019

UEDC, MoE, DEA, EAThis project develops an independent study of the Ukrainian energy system, which analyses development scenarios for input to national energy strategy documents and provides policy recommendations to achieve national energy and climate goals. Furthermore, the modelling results of this project can also be used to contribute to the National Energy and Climate Change Plan for the period 2021-2030 (NECP)
VEOR2021 Vietnam Energy Outlook Report 2021TIMES-Vietnam2021

EREA, DEAThe objective of the project is that Vietnam’s energy system becomes more sustainable through implementation of cost-optimized policy and planning by assisting MOIT and EREA to commission, develop, and analyse comprehensive long-term energy scenarios. 
LTES-AZ Long-term Energy Strategy for AzerbaijanTIMES-AZ (to be dev.)2021

MoE, EQUINOCCIO, Ramboll, NIRASThis technical assistance tackles the needs of Azerbaijan of reviewing and updating the Long-Term Energy Strategy (LTES) in the light of the recent situation in AZ. Another important focus in this technical assistance is to build up capacity in Azerbaijan to continue the work with LTES and in general to work with energy system analysis as a method for planning future investments and points of focus. 


Biannual workshops

The biannual workshops focus on the practice of modelling and use of ETSAP tools e.g. MARKAL/TIMES modelling frameworks, participation in training activities and collaboration in projects related to the improvement of ETSAP tools. In general, the contribution to these workshops shall be based on current and future projects, particular within EU, Nordic and Danish research programs – by involving PhD students from Danish universities.

Our director and partners participated in several IEA-ETSAP semi-annual meetings over last years:

For all past and coming workshops please see here.


Members of EML attended several ETSAP webinars:

  • 2020-11-26: How to build a TIMES model from scratch
  • 2020-12-10: Modelling clean energy transitions: approaches and tools for the World Energy Outlook and the Energy Technology Perspectives
  • 2021-01-21: Developing and using TIMES models with git, GitHub and VEDA
  • 2021-02-23: ETSAP webinar: High temporal and spatial resolution modelling in TIMES models
  • 2021-03-30: Stochastic Modelling of VRES in TIMES and Modelling high VRES with hourly TS resolution, unit commitment, dispatch and capacity expansion in TIMES


Ida participated in the 3 days ETSAP VEDA-Times web training.

For future trainings please see here.


EML is teaching energy system modelling on the basis of the TIMES modelling framework. In the current term Mikkel and Kenneth are offering the course TIMES-DK modelling to graduate students at SDU. The duration is approx. 20 weeks from February to June 2021.


The students are given insights into the TIMES modelling framework and will deploy the Danish model TIMES-DK to assess the Danish energy systems within the scope of their individual assignments.


The course aims to provide the students with knowledge and abilities to work in the TIMES-framework, which includes but is not limited to the following topics:

  • Sector coupling of the full energy system
  • Time aspect in the making of energy system assessment
  • Resources barriers such as bioenergy, wind, solar and fossil potentials
  • Carbon budgets and national GHG targets


Weekly lectures combined with practical assignments and project work in groups. Results of case works are an integrated part of the teaching and will be presented and evaluated during the course.

Auxilliary tools

At EML we develop several auxiliary tools. Currently, we work on two tools, one to include biomass potentials for energy use in our analysis and the other to seamlessly aggregate and transmit data from a VEDA batch export excel file to our websites hosted by Tokni:

  • A biomass model – for more information contact Ida
  • Veda to TOKNI – for more information contact Till

VEDA migration

Within the Nordic Clean Energy Scenarios (NCES2020) project EML migrated the development of the open source Nordic TIMES model (ON-TIMES) from VEDA1 to VEDA2. It includes all of the 5 nordic countries, i.e. Denmark, Finland, Iceland, Norway, Sweden and serves the purpose of informing decision-makers and support the common Nordic commitment to carbon neutrality through strong, collaborative Nordic research and analysis.
