Siemens launches new gas engine E-series with power output of 2 MW

Siemens has expanded its high efficiency and low emissions engines business with the global launch of its new E-series gas engine with a 2 MW output. This new engine series from Siemens, with improved cylinder capacity, will be manufactured at the company’s Zumaia plant in the Basque Country and is particularly designed to improve efficiency in electricity generation, industrial generation and CHP.

The German multinational has chosen the town of Miñano, in Spain’s Vizcaya region, for the global client launch of this new range of engines, complementing its product portfolio and expanding its offer of distributed energy generation. It additionally adds an extensive range of efficient and environmentally friendly products and solutions, as well as significantly saving distributed energy production resources.


By choosing the town of Miñano to present this range to clients around the world, Siemens has demonstrated its commitment to Spain and to Basque industry. These engines will be exported around the globe from the Zumaia plant, while the Miñano R&D centre has established itself as a global reference for research in this field for Siemens.

New business line

This new line of gas engines will be called Siemens Engines and forms part of the company’s Power & Gas division, the specialists in high efficiency and low emissions engines. Siemens has been using the Zumaia factory since 2015 when it acquired Guascor engines and gensets as part of the Dresser-Rand product portfolio. For over 50 years, these engines have been considered as being the most robust on the market, capable of delivering heat and power as well as reliably performing in critical and demanding applications. A total of 4,700 engines manufactured in this Basque factory are currently in operation in over 50 countries around the world.

These engines use latest generation combustion and supercharging technologies, which increase the engine’s capacity, reduce fuel consumption and optimise maintenance costs. They can be driven by a wide range of gases including natural gas, biogas, landfill gas, water treatment gas, syngas and sewerage gas.

New gas engine with a 2 MW output

With this new E-series 2 MW gas engine, Siemens has expanded its portfolio range that covers from 300 kW to 2 MW for gas engines; from 4 to 66 MW for industrial and aeroderivative turbines; and up to 400 MW for heavy duty gas turbines.

The new E-series gas engine is based on the thermodynamic Miller cycle combustion technology that guarantees high efficiency and minimal emissions. With a mechanical efficiency of around 47%, the engine offers a high level of efficiency for both prime power generation and cogeneration applications. This engine has been tested at Siemens’ R&D centre in Miñano and has demonstrated a high level of reliability and efficiency.

The new engine series is the result of in-depth market research to identify key product benefits. In turn, this new gas engine series offers the lowest emissions solution on the market with the smallest footprint at 34.4m<sup>3<sup>.

By generating electricity on site and recovering heat that is typically wasted in a conventional power plant, CHP technology reduces energy costs and carbon emissions. CHP is an application commonly used by large building complexes, such as the one planned for the Siemens Campus in Erlangen, Germany. The Erlangen Campus will create a new urban district and debut as Siemens’ first CO<sub>2<sub>-neutral premises worldwide. In collaboration with Erlangen’s public utility, the campus will operate on a CO<sub>2<sub>-neutral basis, thanks to a state-of-the-art building and its energy technology. It comprises a decentralised energy system that uses a separate cogeneration system based on four new SGE-86EM engines to provide the campus with heating and cooling.

Cutting edge R&D centre in Miñano

Siemens Engines has its own R&D+i centre in Miñano dedicated to the research, innovation and development of new technologies. This is a centre of excellence and an international reference in its sphere of activity, the only one in Spain and one of the most advanced in the world. In addition, this business line employs over 300 people, of which almost 70 are dedicated to R&D. For Siemens, the only way to achieve and maintain its leadership in products and applications is to continuously focus its efforts on research, hence the pioneering R&D centre in Miñano.

With the world launch of this new series of low output engines in Miñano, Siemens has reinforced its support of the Basque Country as one of the autonomous regions that is the most committed to innovation, thanks to the Basque Government’s stimulus of R&D via financial aid and initiatives that foster investment. Unsurprisingly the industry sector in the Basque Country carries important weight in Spain and is positioned as one of the key locations for industry in which to invest and develop. In addition, the Basque County is an attractive region for productive investments, given its easy access to the markets, its quality workforce and good transport connections abroad.
