Narva Electricity Company

from Wikipedia, the free encyclopedia

The electricity works Narva ( Estonian Narva Elektrijaamad ) are a complex of power plants in the Estonian border town Narva .

The facility includes the world's two largest oil shale powered steam power plants , Balti Elektrijaam and Eesti Elektrijaam . In 2007, the power plants in Narva generated about 95% of all electricity production in Estonia. The owner and operator is AS Narva Elektrijaamad , a subsidiary of Eesti Energia .

Balti Elektrijaam

The Balti power plant was built between 1959 and 1965. It is located 5 km southwest of Narva ( ⊙ ). At the end of 2005 it had an installed capacity of 765 MW and provided an additional 400 MW of thermal capacity as district heating for Narva and its surroundings. The cooling water comes from a reservoir that is connected to the Narva River by two 1 km long inlet channels . The power plant has four chimneys that are 149 meters, 150.6 meters, 153 meters and 182.6 meters high.

Eesti Elektrijaam

Eesti Elektrijaam

The Eesti power plant is located about 20 km west-southwest of Narva ( ⊙ ). It was built between 1963 and 1973. At the end of 2005 it had 1,615 MW electrical and 84 MW thermal output. The cooling water comes from the Narva and Mustajõgi rivers through a 7 km long open channel. The power plant has two chimneys, 251.5 meters high, the tallest in Estonia.

Auvere power plant

On January 14, 2011, Narva Elektrijaamad signed a contract with the French plant manufacturer Alstom for the construction of a new power plant near the Eesti power plant. The contract provided for the construction of two 300 MW power plants worth EUR 950 million. The power plants will use circulating fluidized bed combustion , a process that is more efficient and environmentally friendly compared to the older technology of burning oil shale in powdered form. In February 2014 the decision was made against building the second 300 MW unit. The 300 MW block had not yet reached its full capacity by the beginning of 2017.

Ash residue

About 46% of the ash remains from the oil shale that is burned in Narva. The power plants produce 4.5 million tons of ash annually. This is liquefied with water and deposited in deposit lagoons. Balti has two deposit areas, one of which is already closed. The ash is very alkaline, the non-combustible residues of the oil shale are mainly limestone. The lagoons are visible in light blue on satellite images.

Wind farm

In 2010, plans were published to build a wind farm with an installed capacity of 39 MW on the closed ash store of the Balti power plant . In the final stage, the wind park should comprise 17 wind turbines with a nominal output of 2.3 MW each . The Enercon E-82 turbines have a hub height of 107 meters and a rotor diameter of 82 meters. They were attached to the limestone underground with 22 meter long anchors. The wind farm cost 60 million euros and supplies 35,000 households and was completed in 2012.
