The Ministry of Energy of the Republic of Lithuania is the central government department responsible for national energy policy and infrastructure. Its mandate includes ensuring energy security, regulating electricity and heating sectors, and accelerating the transition toward renewable energy. Originally established in 1990, the institution was merged into the Ministry of Economy in 1997 before being reinstated as an independent ministry in 2009 to advance strategic projects like the Klaipėda LNG terminal and European grid synchronization.
