Siemens introduces 2 MW-class E-series gas engines

New SGE-86EM and SGE-100EM E-series gas engines set a new benchmark for more efficient power generation.

For more than 50 years, the family of legacy Guascor® engines has been recognized as robust machines that efficiently generate power and heat in many applications and perform reliably in critical, demanding applications. These products are engineered and tested in rigorous conditions and engineered to meet clients’ specific requirements for each project. Today, more than 4,700 of these units are operating in more than 50 countries.

If you simply click on your computer’s thesaurus icon looking for words comparable to “new,” you find terms such as innovative, contemporary, up-to-the-minute, groundbreaking, and revolutionary, among others.

Such words might well describe Siemens latest entry into the gas engine market – the all-new SGE- 86EM (50Hz) and SGE-100M (60Hz) 2 MW E-series engines, based on Guascor® technology. With 12 cylinders, these new 2 MW E-series engines offer the largest volume per cylinder and higher displacement compared to other high-speed reciprocating engines available in today’s market.

The SGE-86EM engine builds on the success of the thermodynamic Miller cycle system with improved combustion technology and ensures high reliability and minimal emissions. Comprehensive testing at Siemens’ engine R&D Center in Miñano, Spain, demonstrated a reliable, efficient engine with competitive capital expenditures. “The SGE-86EM gas engine offers a more compact and efficient alternative to the 2 MW engines available in the power generation market today,” said Eva Garmendia, product line manager. “And time is money, so we’re positioned to offer one of the shortest lead times in the industry, with just 24 weeks from concept to delivery of a complete SGE-86EM gen-set.”

With the highest electrical efficiency of 45.4 percent in its category, the engine offers a high level of performance for both prime power generation and cogeneration facilities. It is highly reliable and ensures longer run times between service intervals. The SGE-86EM engine’s capacity to deliver on-site power, heat and cooling or a wide variety of commercial, industrial and municipal applications translates into an excellent cost-performance ratio.

“The new SGE-86EM engine is the result of in-depth customer research to identify key product benefits sought by our clients, like small footprint, efficiency, low emissions, quick delivery, and reliability,” said Iñaki Iruretagoiena, R&D director for reciprocating engines. “In turn, this new E-series gas engine offers our clients what we believe are the highest efficiencies in the market, excellent reliability, low emissions, and the smallest footprint – 34.5 cubic meters.”

Siemens E-series engines are particularly suited for industrial power generation and cogeneration, or combined heat and power (CHP).

CHP is a well-documented technology that converts a single fuel, like natural gas, into both electricity and heat in a single process at the point of use. It’s a common application used by large building complexes like hotels, university buildings, municipal facilities, commercial complexes, and district heating facilities with a CHP configuration. By generating electricity on site, and recovering heat that would typically be wasted in a conventional power plant, users benefit from increased energy efficiency and reduced energy costs and carbon emissions.

SGE-86EM engine destined for Siemens’ Erlangen, Germany campus
Siemens joined forces with Erlangen, Germany’s municipal utility to develop a decentralized energy system that uses a separate cogeneration system based on four new SGE-86EM engines to provide district heating and cooling. Combined in a single concept for adaptation to the existing energy infrastructure, this system will eliminate expensive development or expansion of the existing infrastructure to sustainably meet the energy needs of the new urban district. The units are expected to be delivered to the site in 2018.
