• Decarbonising district heating: A profitable pathway to net-zero​

    Sector coupling of district heating and power systems is transformative for Europe's energy future.​

District heating plays a crucial role in accelerating decarbonisation by providing a flexible, integrated, and renewable-based energy system.

District heating is a profitable pathway to net zero.

It is an underutilised flexible energy solution for Europe to achieve cost-effective decarbonisation when used with Combined Heat and Power (CHP) engines.

It has vast potential to drastically scale renewable energy usage by drawing on various renewable and low-carbon heat sources, thus reducing dependency on fossil fuels.

Combined heat and power technology

With its district heating technologies, Wärtsilä is at the forefront of the transition towards a 100% renewable energy future and helps to accelerate to the most reliable, cost optimal, and net zero energy future. 

Sector coupling of district heating and power systems plays an increasingly important role and is transformative for Europe’s energy future. Combined heat and power engines and flexible technology like heat pumps optimise energy use. They dynamically select between heat and power production technologies to adapt to market prices, maximising economic returns. For example, when renewable energy is abundant, heat pumps and electric boilers absorb the extra energy. When solar and wind are low, these engines produce heat for cities and power for the grid, keeping energy supply reliable. 

The Wärtsilä Combined Heat and Power (CHP) plant is a cost-effective and innovative solution where total efficiency can exceed 90%. The most common heat products are hot water or steam, which makes it perfect for both industrial and district heating purposes.

District Heating Utilities in Hungary Start Electricity Generation

Dec 17, 2014, 00:47 by Wartsila Corporation

Wärtsilä Corporation Trade &Technical Press 14 March 2002

Hungarian district heating utilities are expanding their commercial activities into electricity production. This new business move will produce extra income, for the utilities, from the sale of electricity to Hungary’s national grid.  This has been brought about by recent Hungarian legislation, which enables a district heating company to sell electricity below 20 MW to the national grid.

Following tough international competition, Wärtsilä has been awarded three power plant contracts from Hungarian district heating companies. These contracts are Wärtsilä’s first significant power plant projects in Hungary. The contract awards were based on the high electrical efficiency of the Wärtsilä engines.

In the first two awards, Sinergy Kft, one of the leading investment companies in Hungary, chose Wärtsilä to supply engines for two new power plants in in Kazincbarcika and Tiszaújváros. The two plants will use three 18V220SG gas engines at Kazincbarcika and two 18V220SG gas engines at Tiszaújváros with 3.2 MWe power per unit to generate electricity.

The engines will be supplied to the sites by April 2002. The plants will start commercial operation during September 2002. Wärtsilä and Sinergy have also agreed a 10 year maintenance agreement.

In the third contract, Györhö District Heating Company, which supplies heat to the City of Györ, chose Wärtsilä to supply engines for their new power plant. The power plant will use two 18V34SG gas engines to produce a planned output of 10,920 kWth and 12,000 kWe. The engines will be supplied to the site by summer 2002. The new power plant will be fully operational in October 2002. The contract award also includes a 10 year maintenance contract.
