Elektrani na Severna Makedonija

Elektrani na Severna Makedonija or ESM (Електрани на Северна Македонија, ЕСМ, litt. "Power plants of North Macedonia") is a government-owned electricity producing company in North Macedonia.

History
In 2005, the former state monopoly ESM (ЕСМ - Електростопанство на Македонија [], litt. Electricity of Macedonia) was split in three companies:
 * A state-owned power-producing company ELEM (ЕЛЕМ - Електрани на Македонија [], litt. Power plants of Macedonia), in charge of the country's power plants
 * A distribution and supply company, initially called ESM AD, sold in 2006 to Austrian EVN Group and renamed as EVN Macedonia (EВН Македонија), rebranded in 2019 as EVN AD Skopje (ЕВН АД Скопје).
 * A state-owned transmission system operator MEPSO

In March 2019, ELEM was renamed as ESM (Power plants of North Macedonia) after the country renamed itself as North Macedonia with the implementation of the Prespa agreement, reverting to the previous initialism used between 1990 and 2006.
