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.
History of the Iru power plant
- In 1974, construction work started for a combined heat and power plant in Iru to cover the needs of the new Lasnamäe residential district and the town of Maardu.
- On September 30, 1978, the heat produced by the two 116 MW boilers reached the homes of Lasnamäe and Maardu for the first time.
- In May 1981, the first energy unit was commissioned and connected to the power grid and combined production of electricity and heat started. The first energy unit achieved its nominal capacity of 80 MW on February 23, 1982.
- In September 1982, the second energy unit was commissioned with a nominal capacity of 110 MW.
- In 1989, an additional steam boiler DE-25-14 with a capacity of 16.5 MW was installed to cover the internal heat demand when no electricity was being produced
- In 1990, the third boiler was commissioned to cover the heat demand of the district heating network at peak loads.
- In 1993–1998, the steam and water boilers were gradually rebuilt to take gas as their fuel, and since 1999 the Iru power plant has run only on gas, which contains no sulphur and has much lower atmospheric emissions and environmental impact.
- In 1999, the Iru power plant and the district heating pipe systems of Lasnamäe were connected to Tallinn's city centre district heating pipe systems, allowing heat energy production to be increased by nearly a third to make use of the existing unused production reserves.
- - At the end of 2006, preparations were started for a CHP unit burning waste. The Environmental Office of Harjumaa County has approved the assessment of the environmental impact of the construction of the combined unit on the grounds of the power plant.
