The Iru power plant

The Iru power plant, which has the largest potential capacity among all Estonian heat producers, supplies heat to Tallinn and to the town of Maardu. The Iru power plant uses natural gas as its main fuel for combined heat and power generation and liquid fuels as its reserve fuel.

It was in the autumn of 1978 that the two water boilers of the Iru power plant sent heat to the radiators in homes in Lasnamäe and Maardu for the first time. At the end of 1980, the boiler was converted into a CHP plant. The power plant has been continuously renovated and its operation has been optimised in order to increase its efficiency and lower its environmental impact. The environmental management and auditing system of the Iru power plant has an EMAS certificate, and it conforms to the quality management standard ISO 9001, the occupational health and safety management standard OHSAS 18001 and the environmental management standard ISO 14001.

In 2013 Eesti Energia finished building the modern and efficient waste-to-energy power unit at the Iru power plant to generate heat and electricity from mixed municipal waste. With the completion of the Iru waste-to-energy unit, the large-scale depositing of mixed municipal waste in landfills will end in Estonia because for the first time we can use the waste that previously went into landfills as fuel. The Iru waste-to-energy unit is a new solution for Estonia, for both energy production and waste handling.

The electricity production capacity of the 105-million-euro waste-to-energy power unit is 17 MW, and the heat production capacity is 50 MW. It can use around 220,000 tonnes each year of the mixed municipal waste that is left after sorting and collection to generate energy.

The Iru unit converts about 85% of the energy in waste into electricity and heat. The technology used in the waste-to-energy power unit is able to burn several types of waste, and it does not require the mixed municipal waste to be sorted, crushed or sieved prior to combustion.

The electricity production of the Iru waste-to-energy power unit meets the electricity consumption needs of the town of Paide and its surroundings. Eesti Energia transmits heat energy to Tallinn and Maardu residents through the district heating network. The Iru waste-to-energy power unit will have about 20% of the region's heat market.

The waste-to-energy power unit at the Iru power plant was built by a French company, Constructions Industrielles de la Méditerranée (CNIM) to a turnkey contract. General construction work was done by Merko Ehitus Eesti.
