Rolls-Royce has signed a contract with C-Energy to extend their power plant installed capacity with further 23 MWe. The delivery includes two gas-fired gensets based on the new 20 cylinder Rolls-Royce medium speed V-engine, B36:45, that was launched at the Power Gen Asia in September this year. Rolls-Royce will also be supplying long term services for the new engines.

The new B36:45 engine series set a new standard in power and efficiency with exceptionally low fuel consumption and emissions of NOx, CO2, SOx and particulates. At 600 kW per cylinder it offers a 20 per cent increase in power per cylinder compared to its predecessor, the B35:40. The V20 is the largest variant available with an electrical output of 11,8 MWe.

The existing 60 MWe power plant of C-Energy was reconstructed in the beginning of 2015 with four B35:40V20 gas engines. At this time, this was the first natural gas power plant based on medium-speed gas engines in the South Bohemian Region prepared to supply heat and power to the local grid. Due to low coal prices however, electricity and heat in the region is still predominantly generated by coal-fired plants. Hence, the extension of the gas fired plant is considered as an additional step forward towards a green future for the region and country.

With the extension, the power plant will, from the end of 2019, deliver a total of 83 MWe electricity and heat for companies and homes in the nearby town of Tabor/Sezimovo Ústí roughly 100 kilometers southeast of the capital Prague.

Delivery of four Rolls-Royce engines among other investments helped to transform the old coal fired central heating plant into a modern power plant in 2015. Nowadays the plant not only supply power to the grid and heat to industrial customers and municipalities but also provide auxiliary services to the high voltage grid. The supply of brand new Rolls-Royce engines will enable the plant to increase its flexibility, to provide wider range of services and hence remain competitive on the pan European energy market.

The Rolls-Royce medium-speed engines will enable C-Energy to operate the plant efficiently, both in terms of cost and time. Both the B35:40 and the new B36:45 medium speed gas engines are flexibly designed for different operating modes. They can be used to generate base-load or peak power or can operate in combined cycle. The heat from the engines can be used to generate steam in the heat recovery steam generators, and the steam is supplied to industrial customers for their technological needs. The power plant can also be used for district heating by utilizing hot water from the engines.

The engines quick-start capability means the engines can ramp up to their rated load within five minutes, giving the plant access to the amount of power and heat needed within just a short space of time. In addition the new engines will be certified to provide primary and secondary grid regulation.

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.

Siemens has expanded its high efficiency and low emissions engines business with the global launch of its new E-series gas engine with a 2 MW output. This new engine series from Siemens, with improved cylinder capacity, will be manufactured at the company’s Zumaia plant in the Basque Country and is particularly designed to improve efficiency in electricity generation, industrial generation and CHP.

The German multinational has chosen the town of Miñano, in Spain’s Vizcaya region, for the global client launch of this new range of engines, complementing its product portfolio and expanding its offer of distributed energy generation. It additionally adds an extensive range of efficient and environmentally friendly products and solutions, as well as significantly saving distributed energy production resources.


By choosing the town of Miñano to present this range to clients around the world, Siemens has demonstrated its commitment to Spain and to Basque industry. These engines will be exported around the globe from the Zumaia plant, while the Miñano R&D centre has established itself as a global reference for research in this field for Siemens.

New business line

This new line of gas engines will be called Siemens Engines and forms part of the company’s Power & Gas division, the specialists in high efficiency and low emissions engines. Siemens has been using the Zumaia factory since 2015 when it acquired Guascor engines and gensets as part of the Dresser-Rand product portfolio. For over 50 years, these engines have been considered as being the most robust on the market, capable of delivering heat and power as well as reliably performing in critical and demanding applications. A total of 4,700 engines manufactured in this Basque factory are currently in operation in over 50 countries around the world.

These engines use latest generation combustion and supercharging technologies, which increase the engine’s capacity, reduce fuel consumption and optimise maintenance costs. They can be driven by a wide range of gases including natural gas, biogas, landfill gas, water treatment gas, syngas and sewerage gas.

New gas engine with a 2 MW output

With this new E-series 2 MW gas engine, Siemens has expanded its portfolio range that covers from 300 kW to 2 MW for gas engines; from 4 to 66 MW for industrial and aeroderivative turbines; and up to 400 MW for heavy duty gas turbines.

The new E-series gas engine is based on the thermodynamic Miller cycle combustion technology that guarantees high efficiency and minimal emissions. With a mechanical efficiency of around 47%, the engine offers a high level of efficiency for both prime power generation and cogeneration applications.
