Narva Power Plants
The electricity networks Narva ( Narva Estonian Elektrijaamad ) are a complex of power plants in the Estonian border town of Narva.
The system includes the world's two largest oil shale -driven steam power plants, Balti and Eesti Elektrijaam Elektrijaam. 2007 produced the power plants in Narva about 95 % of total electricity production in Estonia. Owned and operated by the company AS Narva Elektrijaamad, a subsidiary of Eesti Energia.
Balti Elektrijaam
The Balti power plant was built in 1959-1965. It is 5 km southwest of Narva ( ⊙ 59.35345228.122876 ). The end of 2005 it had an installed capacity of 765 MW and an additional amount of 400 MW of thermal power for district heating for Narva and its environment. The cooling water comes from a reservoir which is connected via two 1 km long inlet channels with the Narva River. The power plant has four chimneys, which are 149 meters, 150.6 meters, 153 meters and 182.6 meters high.
Eesti Elektrijaam
The power plant Eesti located about 20 km west-southwest of Narva ( ⊙ 59.27342427.899308 ). It was built in 1963-1973. The end of 2005 it had 1,615 MW of electricity and 84 MW of thermal power. The cooling water comes from the rivers Narva and Mustajõgi over a 7 km long open channel. The power plant has two 251.5 -meter high chimneys, the highest in Estonia.
New power plant
On 14 January 2011 Narva Elektrijaamad signed a contract with the French Alstom plant on the construction of a new power plant near the Eesti power plant. The contract provides for the construction of two 300 MW power plants at a value of 950 million euros. The power plants will work with circulating fluidized bed combustion, a process that is efficient and environmentally friendly compared to the older technology to burn the oil shale in pulverized form.
After this contract is to be built by 2015 a first 300 - MW plant for 540 million euros. The decision on the contract for a second 300 MW plant for 410 million euro to fall in 2012.
Ash residues
From oil shale, which is burned in Narva, remains about 46 % ash. The power plants produce 4.5 million tonnes of ash annually. This is liquefied with water and deposited in Deposit lagoons. Balti has two deposition areas, one of which is already closed. The ash is very alkaline, the incombustible residue of the oil shale is mainly limestone. On satellite images, the lagoons are visible in bright blue.
Wind farm
There are plans to build on the closed ash - storage power station Balti a wind farm with an installed capacity of 39 MW. When completed, the wind farm will comprise 17 wind turbines produces 2.3 MW. The Enercon E-82 have a hub height of 107 meters and a rotor diameter of 82 meters. They are secured with 22 meter long anchors in the limestone subsoil. The wind farm will cost 60 million euros, 35,000 households will provide and be completed in 2012.
