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.

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.

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.

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.

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 utilizing 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.

MAN Diesel & Turbo has been commissioned with the planning and, upon investment approval, the construction of a 30 MW  gas engine power plant by Energie Baden-Württemberg AG (EnBW). The combined heat and power plant (CHP) at the Stuttgart-Gaisburg site will be operated using three MAN type 20V35/44G gas engines and will not only supply electrical power but also an additional 30 MW of district heating.

Commissioning is scheduled for 2018.  “This is our second engine CHP plant in Germany and an important milestone in further establishing the highly efficient gas engine technology”, says Wayne Jones, Member of the Executive Board for Global Sales and After Sales at MAN Diesel & Turbo. “The new plant, consisting of boilers, heat storage and gas engines, will serve to replace a mainly coal-fired thermal power plant at the same location and has a particularly high fuel utilisation rate due to its overall efficiency of more than 85% (without tolerance). Switching from coal to gas will reduce CO2 greenhouse gas emissions by up to 60,000 tonnes per year.”MAN2

With an increasing share of renewable energies in electricity production, flexible gas engine power plants with cogeneration are the perfect solution for security of supply, efficiency and the reduction of emissions. The combination of gas engines with CHP and district heating storage makes it possible to decouple electricity and district heating supply, meaning that the operator can respond flexibly to pricing signals. “We are investing in climate protection and security of supply,” states Diana van den Bergh, Project Manager at EnBW. “The new gas engine power plant will significantly reduce site emissions and contribute to improving the air quality in Stuttgart. The site in Gaisburg has been generating heat and electricity for the Stuttgart area for over 60 years. The modernisation will ensure that the site can fulfil these tasks even more efficiently and environmentally friendly in future.” Large gas engines are particularly well-suited when it comes to the supply of district heating and they are superior to other generation technologies of this plant size. This was confirmed in a recent study by the University of Duisburg.
