The Ledvice Power StationThe Ledvice Power Station

New: Virtual tour! The new power source in Ledvice – the most state-of-the-art traditional power station in Central Europe – has been erected on the site of the existing Ledvice coal power station. It offers unique views due to its position between the Central Bohemian Uplands (Ceske stredohori) and the eastern foothills of the Ore Mountains (Krusne hory). It is visitors to the 140-meter tall lookout point on the tallest industrial structure in the Czech Republic who will appreciate the views the most. Nevertheless, our virtual tour will enable a much wider public to enjoy a similar experience, especially those interested in industrial tourism.

Originally, the Ledvice power station had five units, built in 1966 – 1969, with Unit 1 having an installed capacity of 200 MW and Units 2 through 5 having 110 MW each.

Units 1 and 5 were shut down in the 1990s, Units 2 and 3 were equipped with flue-gas desulfurization systems in the mid-1990s, Unit 4 went through a major reconstruction – the original granulation boiler was replaced with a fluidized bed combustion system in 1998, and the turbine was replaced in 2007, with the new one being optimized for heat generation although its capacity stayed at 110 MW. Units 3 and 4 were taken out of operation in 2013 and 2015, respectively.

Presently, it is only the 110 MWel Unit 4 that is in operation, together with the new Unit 6 with an installed capacity of 660MWel.

A newly erected gas boiler station with a steam generation capacity of 160 t/hr is now used as a back-up source.

Apart from generating power, the Ledvice power station also supplies heat to customers in the nearby municipalities, and by means of CEZ Teplarenska a.s. it supplies heat in the form of steam to the cities of Teplice and Bílina, and in the form of hot water to the town of Ledvice as well. The combined generation of power and heat in one cycle, referred to as co-generation, reduces fuel consumption per unit of energy produced, which also helps the environment.

The total annual amount of heat supplied to customers is approx. 1,000 TJ, with the maximum capacity currently being some 150 MWt. The installed capacity allows up to 270 MWe to be supplied to heat systems. Therefore, the power station has a considerable performance buffer that allows other customers to be connected (e.g., the town of Duchcov) and the volumes supplied to existing customers to be increased. The benefit of supplying heat from a power station are reasonable and competitive prices as well as supply stability in terms of operational availability and price.

In PP Ledvice, brown coal of 11 – 13 MJ/kg CV (calorific value) from Bilina Mines is burnt. The coal is transported directly on belt conveyers from the nearby Ledvice Coal Cleaning Plant, either directly to boiler coal bunkers, or to an operation deposit of 40 000 t capacity, supporting the power plant operation in case of emergency in coal transport or mining.

The main water sources are provided from Elbe River, with Vsechlapy Dam as a backup water source. Water filtration and demin treatment takes place in a modern water chemical treatment plant, having adequate parameters to ensure required both quantity and quality of service water for steam circuits of power plant production units.

Apart from electricity production, PP Ledvice supplies heat power for customers in nearby vicinity, and it provides heat power to the towns of Teplice and Bilina, through United Energy utility company. The electricity and heat power production combined in a single cycle, i.e. co-generation, reduces coal consumption per a power unit produced, thus partially eliminating environmental effects.

The total yearly supply of heat power to various customers equals to, approximately, 1 000 TJ, with the maximum heat power output of 150 MW. The power output installed for heat supplies equals to 380 MW, and the water chemical treatment plant allows for 270 MW supplies to heat distribution networks. The power plant, therefore, features a substantial power output reserve, providing for a possible connection of other consumers (the town of Duchcov, e. g.), and an increase in supplies to existing locations.

Production unit - new power source Ledvice
Installed power output 1x 110, 1 x 660 MW
Operation commenced in the year 1966-68, 2014
Desulphurized since the year 1996 (2 x 110 MW) 1998 (1 x 110 MW – fluidized bed boiler)

 

Secondary power-producing products

Based on the burning process in the course of the production of electric energy and heat, there are generated the secondary power-producing products that become, on the assumption that the technical and legal conditions have been met, the raw material for further processing and production.

The waste generated in the burning and desulphurization process is transformed to a secondary raw material usable namely in the building industry and recultivation of the worked-out Fučík quarry. The raw material in question is the so-called stabilizate that is generated in the mixing equipment from the end-product of desulphurization, ash and water.

Heat - The Ledvice Power Station

In addition to production of electric energy, The Ledvice Power Station provides heat supplies for customers in the nearby vicinity, and it also provides heat power to the towns of Teplice and Bílina, through United Energy utility company. The electricity and heat power production combined in a single cycle, the so-called co-generation, reduces fuel consumption per a power unit produced, thus partially eliminating environmental impacts.

The total annual supply of heat power to various customers equals to, approximately, 1,000 TJ, with the maximum heat power output of 150 MW. The power output installed for heat supplies equals to 380 MW, and the waste water chemical treatment plant capacity allows for 270 MW supplies to heat distribution networks. The power station, therefore, features a substantial power output reserve, providing for a possible connection of other consumers (e. g. the town of Duchcov), and an increase in supplies to the existing locations.

Advantages of heat supply from the power station include reasonable and competitive prices, and operating-technical and price stableness of supplies.

When can you visit us?

The Ledvice Information Centre is open to the public Monday to Friday always from 7 a.m. to 3 p.m. In case of larger groups the visit can be booked in advance via telephone at 411 10 2313 or by e-mail: infocentrum.ele {zavináč} cez {tečka} cz. The Information Centre was built within the ongoing complex renewal of coal power plants and construction of the new generator in Ledvice. Modernisation of power plants will result in further improvement of the environment in the North of Bohemia.
