Wärtsilä gas power plants
Wärtsilä gas power plants are designed for optimal production performance in a broad variety of peaking, intermediate and baseload applications. The power plants are based on modular 4–19 MW engine units operating on gaseous fuels.
Wärtsilä gas power plants offer high output and high simple cycle efficiency even in the most challenging ambient conditions and locations. The power plants offer world-class operational flexibility with uniquely fast starts, stops and restarts, ensuring perfect control over daily load fluctuations.
The benefits of gas power plants include:
- Stepwise investment with smaller risks and optimized profit generation
- Excellent plant availability and reduced need for backup capacity due to multi-unit installation
- Net plant electrical efficiency of over 49%
- Full plant output at high altitudes and in hot and dry ambient conditions
- High part-load efficiency
- Fast start-up, 5 min from hot standby to full plant load
- Minimal water consumption with closed-circuit radiator cooling
- Low gas fuel pressure requirement
- Maintenance schedule independent of the number of starts or trips.

The Wärtsilä GasCube is a complete one-engine power plant, based on the most powerful Wärtsilä 34SG engine, with all the auxiliaries and components needed to make up a working power production unit, providing close to 10 MWe per unit. Several GasCubes can be connected to each other to increase total plant output.
Due to the self contained design, the GasCube is the optimal solution for agile, streamlined and exceptionally cost efficient project execution. The Wärtsilä GasCube consists of a prefabricated building that has the engine and the alternator located on a common baseframe.
All auxiliaries are located in the modules. The auxiliary module includes a gas regulating unit, the cooling system, an instrument air system and an engine pre-heater. The inlet air module, charge air silencers, exhaust gas system and an auxiliary module are all connected to the genset. The radiators for engine cooling are installed on the roof. The starting air compressor, starting air vessel and the maintenance water tank are installed next to the generating set.
The closed-circuit cooling systems used in the GasCube make it the perfect choice for remote locations or any location in which water is scarce.
All Wärtsilä gas power plants are also designed to give full output and high performance in hot and dry conditions, as well as at high altitudes. New possibilities for Cube placement are opened up by the Cube’s simple interface and small footprint. A typical storage yard of an industrial company, for example, would be more than adequate as a location for this compact solution offering excellent power density.
- High electrical efficiency through minimizing the plant’s own consumption
- Simple and reliable technical solutions
- Compact, pre-engineered design
- Perfect for turnkey (EPC) deliveries even to areas lacking infrastructure

Depending on power plant solution Wärtsilä engines are able to run on a wide selection of fuels, ranging from natural gas to fuel-water emulsions.
Fuels such as crude oil, fuel-water emulsions, associated gas, liquid biofuel, biogas and other fuels outside globally recognized standard fuel specifications, should be carefully analysed for each power plant project prior to use. Due to the nature of these types of fuels their quality might vary over time and consequently fuel quality analysis should be done on a regular basis.
One of the principal aims of Wärtsilä’s Power Plants business is to maintain a high level of expertise in cleaning methods for different effluents from power plants and to offer a variety of tested emissions reduction technologies for different market needs.
The engine generating sets used in Wärtsilä power plants are driven by heavy-duty medium-speed four-stroke combustion engines. These generating sets consist of an engine connected directly to a generator via a flexible coupling. The generator and engine are rigidly mounted on a common baseframe.

The Wärtsilä peaking plant is designed as a pre-engineered, gas-fired power system allowing the users to generate their own power when electricity demand is at its highest. The Cogentrix plant is based upon 20 Wärtsilä 18V34SG natural gas engines, at 5.7 MWe per unit. »
Wärtsilä Corporation was awarded a major power plant contract for an 84.8 MWe replacement and extension of an existing diesel power plant at Manisa in western Turkey. It involved the first Wärtsilä 50DF generating sets for a power plant installation, while Wärtsilä 34SG sets were added in the extension. The new plant allowed a change of fuel from heavy fuel oil to natural gas.
Wärtsilä supplied a 116 MW gas power plant for the Canadian gold mining company Barrick Goldstrike Mines Inc.'s mine project in Nevada, USA. The plant, which is Wärtsilä's largest gas power plant to date for decentralized generation, was delivered to the customer as a turnkey contract. »
The Gyõrhõ combined heat and power (CHP) plant, which supplies power to the city of Gyõr in Hungary and heat to the city's district heating system, is an example of fast-track supply in two phases. The total plant features three Wärtsilä 18V34SG gas engines... »
The Wärtsilä 20V34SG generating set is situated in the Rindum plant. Weighing 130 tonnes, it has a net output of 8 MWe and 9.6 MWth. The new plant delivers heat to the town's 9000 inhabitants and electricity to the local utility company RAH. »
The Wärtsilä CHP plant, consisting of two Wärtsilä 18V34SG engines, is now the largest power plant powered by gas engines in Finland. It has a 12 MWe capacity and produces about 60,000 MWhe of electrical energy per year. »
