The power plant has three operational units with capacities of 80 MW, 110 MW accordingly and 67 MW. The primary fuel of the units 1 and is natural gas and reserve fuel is fuel oil. total installed capacity of units 1 and 2 is 190 MW of electricity, 661.5 MWth of hot water and 162 of MWth steam.[1] In co-generation mode the thermal capacity is 398 MW. It supplies heat to Maardu, and the Lasnamäe and central districts of Tallinn.

In 2006, Eesti Energia started preparations for construction of a waste incineration unit with capacity of 50 MW of heat and 17 MW of electricity. Construction started in 2010.[2][3][4] It was commissioned on 16 June 2013.[5] The unit processes up to 220,000 tonnes of mixed municipal waste per year. The unit was built and technology was provided by Constructions industrielles de la Méditerranée (CNIM). The general construction was carried out by Merko Ehitus, with the incineration grate supplied by Martin GmbH and the system for the treatment of waste gas by LAB, a subsidiary of CNIM. The unit cost about €105 million.[2][3]
