Lithuanian Energy Institute (LEI)

Lithuanian Energy Institute (LEI)  is an internationally recognized energy-related research, development, and innovation (R&D&I) competence center. LEI is a Public institution.

It was established in 1956 and became known among local and international scientific societies interested in fundamental research in hydrodynamics, thermal physics, material science, simulation and control of power supply systems, hydrology, and energy economy. The current name of the Institute was given in 1992 by the Government of the Republic of Lithuania.

LEI is a state technical research center dealing with energy-related research in mathematical modeling of power systems and networks, investigation of their control issues; modeling and optimization research of ICT-based control systems of power systems; renewable energy; analysis of security of energy supply; development of energy planning methods; fuel cells and hydrogen; thermal physics and fluid mechanics; nuclear safety; structural integrity assessment of components and structures; simulation of complex energy systems. LEI has 235 employees (as of January 2024). The Institute has extensive experience in international projects: Horizon Europe & EURATOM, Digital Europe, LIFE, H2020, Intelligent Energy Europe, COST, Eureka, IAEA, INTERREG-type, Nordic Energy Research programme, EuropeAid, etc.

The mission of LEI is to: conduct research and develop innovative technologies in the fields of energy, thermal engineering, environmental engineering, measurement engineering, materials science, and economics, to carry out fundamental and applied research, to participate in study processes, to transfer the results of applied research and innovations to industry, to advise the state, the government, public, private institutions, and companies on issues related to the development of sustainable energy in Lithuania, to cooperate actively with higher education institutions in the preparation of specialists for the Lithuanian society.

Scientific activities of LEI:

  • Research on renewable energy and enabling technologies.
  • Environmental impacts of climate change and anthropogenic activities.
  • Research on economic development towards a climate-neutral society.
  • Energy systems modeling and control research.
  • Safety and reliability studies on industrial and energy facilities.
  • Thermal physics, gas, and fluid dynamics, and metrology.
  • Research on decommissioning of nuclear installations and radioactive waste management.
  • Research on hydrogen technologies for energy, transport, and industrial applications.
