Balti Power Plant

The Balti Power Plant was built between 1959 and 1965. It is located 5 kilometres (3 mi) south-west of Narva, around 59.269565° N, 27.902184° E. As of the end of 2005, Balti Power Plant had installed capacity of 765 MW. The installed thermal capacity was 400 MW. The cooling water is supplied from the Narva Reservoir

The Narva is a river flowing into the Baltic Sea, the largest river in Estonia. Draining Lake Peipsi, the river forms the border of Estonia and Russia and flows through the towns of Narva/Ivangorod and Narva-Jõesuu into Narva Bay. Though the river is only 77 km long, in terms of volume...

 via two 1 kilometre (0.621372736649807 mi) long inlet channels. The Balti Power Plant is the sole supplier of thermal power for the district heating system of Narva.

The Balti Power Plant is divided into an old and a new part. The old part initially had eighteen TP-17 boilers and eight 100 MWe turbines. Four boilers and two turbines are currently in operation, while the others have been taken out of service. The new part has eight TP-67 boilers and four 200 MWe turbines. All these boilers use the pulverized combustion (PC) technology. In 2003, the Unit 11 was reconstructed to use the circulated fluidized bed combustion (CFBC) technology, which is more efficient and environmental-friendly (lower SO2 and CO2 emissions) than PC technology.

Balti Power Plant has 4 chimneys, which are 149 metres, 150.6 metres, 153 metres and 182.6 metres tall.

Eesti Power Plant

The Eesti Power Plant is located roughly 20 km west-south-west of Narva, around 59.353452°N 28.122811°E. It was built between 1963 and 1973. As of the end of 2005, Eesti Power Plant had installed capacity of 1,615 MW. The installed thermal capacity was 84 MW. Cooling water is supplied from the Narva River and Mustajõgi River via a 7 kilometres (4.3 mi) long open channel.

The Eesti Power Plant initially had sixteen TP-101 boilers and eight 200 MWe steam turbines. Fourteen boilers and seven turbines are currently in service. In 2003, the Unit 8 was reconstructed to use the CFBC technology.

Eesti Power Plant has two 251.5 metres tall chimneys, which are the tallest chimneys in Estonia.

New power plant

On 14 January 2011, Narva Elektrijaamad signed a contract with the French power engineering company Alstom
Alstom is a large multinational conglomerate which holds interests in the power generation and transport markets. According to the company website, in the years 2010-2011 Alstom had annual sales of over €20.9 billion, and employed more than 85,000 people in 70 countries. Alstom's headquarters are...

 for construction of the new power plant next to existing Eesti Power Plant. The €950 million contract foresees construction of two 300 MW oil shale-fired units. The units will utilize circulating fluidized bed boiler technology.

According to the contract, a first unit of 300 MW will cost €540 million. There is an option for a second unit of 300 MW for €410 million. The first unit will be completed by 2015. A decision on construction of the second unit will be made in 2012.

Ash disposal

 burnt at Narva plants produces roughly 46% ash, so the stations produce about 4.5 million tons of ash per year. The ash-disposal system involves washing it away with water, and the dirty water is stored in ash-storage lagoons which appear bright blue on the satellite photos. Balti has two storage areas; the western one is divided into twelve sub-regions by banks about three metres wide, and is already closed. The eastern one is in current use and is divided into three sub-regions. The ash is highly alkaline, since the non-combustible portion of the oil shale is essentially limestone.
