Rolls-Royce Gas Engines Assist Slovakia’s Strategy for Greener Power Supplies
Rolls-Royce has signed a contract with EPC contractor TTS Martin, s r o for the supply of a 28 MWe power plant for state-owned utility Martinska teplarenska, a s in Slovakia.
The plant will be equipped with three Rolls-Royce Bergen B35:40V20AG2 natural gas engines and four hot-water boilers, replacing their entire existing coal operation. As well as electricity, the engines and boilers will supply over 28 MW of heat to most of the 60,000 population of the cities of Martin and Vrutky.
The upgrade of the district heating plant is part of Martinska teplarenska’s strategy towards green, sustainable power supplies and the winding-down of their coal operations. They made a strategic decision to invest in gas-fuelled reciprocating engines and gas boilers as a more long-term solution than exhaust gas aftertreatment systems to reduce the emissions given off by coal-fired power plants.
The B35:40 gas series meets the increasingly stringent emissions requirements, with exceptionally low emissions of NOx, CO and UHC combined.
“Martinska teplarenska heating plant is currently using mainly low-quality lignite for heat production – which is both low-output and non-ecological. Especially in the conditions prevalent in the Martin region – which is surrounded by mountains and unable to dispel pollution – it is crucial to look for the most effective, most ecological solutions for heat and power production. For TTS Martin, as a specialist in combined heat and power plants using internal combustion engines, Rolls-Royce Bergen gas engines represent exactly this type of modern, green solution, and therefore we are very pleased to be working with Rolls-Royce on this project,” said Ondrej Korec, CEO of TTS Martin, a s.
The new Martinska teplarenska plant is planned to go into commercial operation at the beginning of 2020, and will be Rolls-Royce’s second power plant using B35:40 Bergen gas engines in Slovakia. The first will under commissioning in May 2019, generating a total of 37 MWe of heat and power for district heating company Teplaren Kosice, a s.

Since Rolls-Royce supplied its first medium-speed gas engine in 1991, Bergen engines have logged millions of operating hours across a broad span of applications and environments.
Some 300 B35:40 gas engines are currently in operation in power plants across the world.
Rolls-Royce medium-speed engines are designed flexibly for different operating modes, and can be used to generate base-load, peak power or operate in combined cycles. By utilising hot water from the engines, the plant will be used for district heating in the surrounding area.
Heat from the engines can also be used to produce steam in the heat recovery steam generators in order to supply industrial customers if required.
