  • The TSO will leverage Energy Exemplar’s PLEXOS modelling software to inform optimal investment decisions for expansions and upgrades to Serbia’s existing transmission system
  • The TSO will use Energy Exemplar’s PLEXOS to assess adequacy of balancing capacities in Serbia in high RES integration and national trends scenarios
  • Energy Exemplar and its partners will work with EMS on full implementation and capability building to unlock the new platform


Salt Lake City – Elektromreža Srbije (EMS), the Transmission System Operator (TSO) for Serbia, will use Energy Exemplar’s modelling software PLEXOS to meet key objectives and manage a changing energy mix.

Through its mid-term and long-term development strategy for the following ten-year period, EMS plans extensive investments to renew the existing and construct new transmission capacities.

Over a three-year initial agreement period, PLEXOS modelling will allow EMS to use simulation technologies to model future investments, including investments in new conventional and renewable energy sources and infrastructure. Electricity production in Serbia currently relies on low-quality lignite for approximately 70% of its energy needs. Modelling future energy scenarios and the long-term effects of greater investment into alternative energy will help Serbia to improve energy security and affordability and to integrate renewable energy storages.

Serbia’s access to the Danube has provided a firm foundation for the domestic production of hydroelectricity.  Hydropower plants produce cca 30% of power electricity and it is very important for EMS to accurately model hydro energy capacities.

Nebojša Vučinić, director of Development Directorate at EMS, commented: “Energy markets across Europe are undergoing rapid and unprecedented change. Utilising technology will be key to ensuring this transition is smooth. PLEXOS gives us the capability of testing scenarios around supply and demand, storage, pricing and integrating new forms of energy so EMS knows the impacts across long term asset investments.”

Michael Schneider, Senior Vice President and Head of EMEA at Energy Exemplar, said: “Energy Exemplar are delighted to be working with EMS. EMS is playing a key role in helping Serbia to modernise and expand its energy infrastructure, as well as reducing the costs associated with line losses and investments while planning for a future-proof energy system.

“PLEXOS modelling will help simulate potential losses and future scenarios towards making more intelligent and informed decisions about the form and nature investment should take.”

Bordering eight countries, Serbia plays a pivotal role in the energy trade in the region. Other adopters of the solution, who have access to similar data sets, will, as a result of the agreement, be able to work more closely with Serbia to ensure fair and predictable prices, and mitigate risks.

Extensive modelling of line losses (the power lost in an electrical conductor during energy transmission and distribution) will help EMS better understand and manage costs, and procure energy necessary for the compensation of transmission grid losses.

Simulating markets will help EMS to plan short-, medium- and long-term procurement decisions, forecasting losses and investment opportunities. The global adoption of new energy technologies will further complexify energy markets. With PLEXOS, Serbia will remain resilient to change, risk and unpredictability.
