Rolls-Royce has signed a contract with EPC contractor Energyco for the supply of four gensets to a cogeneration plant in Kosice, Slovakia. Based on the medium speed gas engine B35:40V20AG2, the plant will generate a total of 37 MWe heat and power for the district heating company Teplaren Kosice a.s. The contract will also include a service agreement for 5 years. The engines are produced at Bergen Engines AS, which is part of Rolls-Royce Power Systems.

One of the critical parameters required by TEKO was 3 minutes start to full load to comply with Slovakian grid support service.

The medium speed engines from Rolls-Royce are flexibly designed for different operating modes, and can be used to generate base-load, peak power or operate in combined cycle. Already three minutes from start, the engines can operate with 100 per cent load to the rated speed of 750 rpm, and are in this aspect well suited to balance changes in the grid parameters. Furthermore, by utilizing hot water from the engines, the plant will be used for district heating for the region. Heat from the engines can also be used to generate steam in the heat recovery steam generators, to supply industrial customers.

Cogeneration plants based on our medium speed gas engines are a reliable alternative to coal-based plants and significantly more environmentally friendly. In addition, the engines’ flexibility will enable Teplaren Kosice to operate efficiently, both in terms of cost and time”, said Jeff Elliott, Managing Director of Bergen Engines.

This will be Rolls-Royces first delivery of medium speed reciprocating engines to Slovakia, complimenting the installed base of 96 MWe in central Europe. The plant is scheduled to be commissioned early 2019.

At 11.6 metres long, 4.5 metres wide and almost 8 metres high, the dimensions of each of the four Bosch boilers for the new Ledvice power plant unit of the energy company CˇEZ are impressive. In total, the boilers produce up to 167 t/h of superheated steam for the start-up process of the new steam turbine that generates power. However, the Ledvice power plant does not just supply power: it also provides heating to some 300 companies and 20,000 residents. The huge boilers provide additional supply during peak load periods and serve as a backup for the district heating network.

The Ledvice power plant is situated in the Czech Republic in the foothills of the Erz Mountains between the cities of Teplice and Bilina. This new power plant unit, with its formidable electrical power output of 660 MW, is owned by the utility CˇEZ and has recently come online at this site.

In its role as general contractor, the company Skoda Praha Invest was responsible for implementing the new turnkey power plant unit and the steam boiler system. Stringent safety requirements and a tight time schedule demanded a high degree of flexibility and experience from all those involved in the project. Read more…
