First of a new breed of gas engines delivered

Rolls-Royce has completed manufacturing of the first of the new medium speed B36:45V20 gas engines at the Bergen Engines facilities in Norway. Two generator sets have now been shipped to its new home in the Czech Republic, for the independent power provider C-Energy.

The B36:45V20 engine is 14 metres long and 5 metres high, has a weight of 170 tonnes, and is the largest and most powerful medium speed engine that has been developed and manufactured by Rolls-Royce. It 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 the two 20 cylinder engines will extend C-Energy’s existing power plant with further 23 MWe. The extension of the gas fired plant is considered as an additional step towards a green future for the region and country where electricity and heat are still predominantly generated by coal-fired plants.

Libor Dolezal, CEO of C-Energy said: “We decided to install the new type of Rolls-Royce’s largest engines to enhance the plant’s thermal capacity as part of our overall strategy to reduce heat and electricity production from coal and also to expand the energy business. Given our very good experience with four engines B35:40V20, we decided to install new types providing us both higher output and efficiency in cogeneration production. It is quite exciting being the very first customer of this new type of engine, the largest one in the Rolls-Royce portfolio of medium speed engines.”

The existing 37 MWe power plant of C-Energy, located in the in Planá nad Lužnicí roughly 100 kilometers southeast of the capital Prague, was reconstructed in the beginning of 2015 with four B35:40V20 gas engines from Rolls-Royce. At this time, this was the first natural gas power plant based on medium-speed gas engines in the South Bohemian Region of the Czech Republic.

With the extension, the gas engines of the power plant will, from the end of 2019, deliver a total of 60 MWe electricity and heat for companies and homes in the nearby town of Tabor/Sezimovo Ústí. Rolls-Royce and C-energy has an agreement for a new service contract.
