Slovakia coal plant refitted with gas engines for CHP

A coal-fired district heating plant in Slovakia is to be upgraded to a CHP facility running on gas engines.

Rolls-Royce has signed a contract with EPC contractor TTS Martin to supply the engines to the plant, which is operated by state-owned utility Martinska teplarenska.

The plant will be equipped with three Rolls-Royce Bergen natural gas engines and four hot water boilers, replacing the 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 sustainable power supplies instead of coal operations. The company made a strategic decision to replace its coal plants with gas-fuelled reciprocating engines and gas boilers.

The Martinska teplarenska plant is due to be operational in 2020 and will be Rolls-Royce’s second plant using B35:40 Bergen gas engines in Slovakia. The first – for district heating company Teplaren Kosice – will be commissioned later this month, generating a total of 37 MWe of heat and power.

TTS Martin chief executive Ondrej Korec explained that the 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.”
