Please find below the latest release from Energy Exemplar on how they are helping shape energy security and energy transition within the Baltics.

Energy Exemplar, which offers energy modelling on future scenarios, already provides this service to the UK National Grid and, in addition to supporting nations and companies globally, provides Estonian, Latvian, and Lithuanian Transmission System Operators with its PLEXOS model. This geographic coverage shows the important role the product will have on energy markets and specifically with Lithuania will aid in collaborating with other Baltic states to align with the rest of the European power market by 2025.

CEO David Wilson is available for interview on this topic and on the wider issues of how modelling can inform billions worth of energy transition investment, ahead of COP 27.

Lithuanian Energy Institute to use PLEXOS software to support Baltic energy transition

  • The LEI will use PLEXOS modelling to support Lithuania’s climate aims.
  • The three-year agreement with Energy Exemplar will allow for closer collaboration with Baltic energy players.
  • PLEXOS will enable the LEI to model the short-term dynamics of national electricity markets.

The Lithuanian Energy Institute (LEI) today announced a three-year agreement with Energy Exemplar to use their PLEXOS simulation modelling software to aid energy market research in Lithuania and the rest of the Baltic countries.

The software will allow the LEI to model the short-term dynamics of electricity and other energy markets and analyse regional energy pricing to help inform policy decisions.

The LEI is an internationally recognised research and development institute based in Kaunas, Lithuania. Among other research areas, it models the development and operation of energy systems and conducts research into planning, energy security and the future of renewables.

As the energy crisis continues to impact the Baltic states of Lithuania, Latvia and Estonia, day-ahead power prices recently hit the price ceiling of €4,000/MWh per peak hour as demand outstripped supply. This should be seen in light of the Baltics’ wider energy goals, which include greater energy independence, the Baltic Energy Market Interconnection Plan (BEMIP) for integrating regional gas and electricity markets with the EU, and the Baltics’ 2030 greenhouse gas (GHG) emissions targets, with Lithuania’s being a 55% GHG reduction in line with the EU’s.

With the Estonian, Latvian, and Lithuanian Transmission System Operators already using PLEXOS, the move will aid in collaborating with other Baltic states to align with the rest of the European power market by 2025. Additionally, the LEI was seeking a modelling solution capable of handling the increasing complexity of energy markets and modelling various energy sources including electricity and gas within one platform by means of sector coupling and Power2X.

Vidas Lekavicius, Chief Research Associate at LEI, said: “The Lithuanian Energy Institute researchers have extensive experience modelling energy development, especially in long-term energy planning. However, reflecting short-term issues in existing models has been difficult, even with the development of specific methods to overcome the limitations of modelling tools.

The PLEXOS tool will become essential to our existing modelling toolbox. We are particularly interested in PLEXOS’s ability to model the short-term dynamics of electricity markets. This is an area of particular research interest in Lithuania, not only due to the increase in electricity prices but also due to the future trends in which energy markets are becoming increasingly volatile with the increasing share of variable renewable energy sources.”

Michael Schneider, Senior Vice President, and Head of EMEA at Energy Exemplar, said: “This agreement marks a crucial moment in Lithuania’s energy industry because the LEI is one of the region’s most respected and innovative research and development centres. It is hugely significant that they have chosen PLEXOS to help them model, optimise and plan for the future of their energy system as this platform is widely used across the Baltics.”
