INNIO’s Waukesha Gas Engines Provide High Overall Efficiency and Low Emissions to District Heating Plant in Germany
- INNIO Announces Successful Commissioning Using Waukesha VHP 9394GSI Gas Engines
- S&L Energie-Projekte GmbH, INNIO’s Authorized Channel Partner for Waukesha Gas Engines, Provided Four Waukesha Engines to Stadtwerke Lutherstadt Wittenberg GmbH
- Waukesha Gas Engines with German Grid Code Certification Exceeded Customer Expectations for Overall Efficiency and Emissions
Waukesha, WISC.— April 24, 2019
— As Germany aims to cut greenhouse gas emissions by 40% by 2020, INNIO* is a key enabler and integral part of the energy transformation with its gas engine technology. As an example of this, INNIO announced the successful commissioning of a modernized district heating plant with Waukesha* VHP* 9394GSI rich-burn gas engines with grid code certification supplied by its authorized Channel Partner for Waukesha gas engines, S&L Energie-Projekte GmbH (S&L). The plant meets high overall efficiency (electrical and thermal) and low emissions. For the project, S&L provided four packages of INNIO’s Waukesha gas engines to Stadtwerke Lutherstadt Wittenberg GmbH in Germany.
“In comparison with the previous combined heat and power (CHP) plant, the overall efficiency of the new CHP plant is significantly higher. Our testing shows that the modernized district heating plant achieves a significant overall efficiency that is well above the guaranteed zero tolerance value of 95%, and the emission values are well below the legal national requirements,” said Hans-Joachim Herrmann, executive director, Stadtwerke Lutherstadt Wittenberg GmbH. “S&L completed the project on time and also provided a solution of INNIO’s Waukesha gas engines that not only met, but exceeded our performance and emissions requirements.”
INNIO’s technology provided the Wittenberg district heating plant with NOx emissions to meet Stadtwerke Lutherstadt Wittenberg’s challenging emission requirements. Emissions of the new plant are about 80% below future national requirements. INNIO’s rich-burn engines can meet these requirements by using a three-way catalyst. S&L supplied the generator for the genset package, performed the grid code certification and provided the balance of plant for the engines.
“With two renowned brands in the portfolio—Waukesha and Jenbacher* gas engines—INNIO can offer solutions that meet the customers’ requirements, independent of whether they are looking for higher electrical efficiency and to operate at higher loads or if they need higher heat output while achieving lower emissions levels and a higher flexibility regarding transient loads and ambient conditions,” said Norbert Hetebrüg, Executive Director Sales Europe at INNIO. “As a solution provider, INNIO can help customers choose the right technology depending on emission requirements, electrical and thermal efficiency and economical evaluation criteria.”
Situated 60 kilometers (37 miles) north of Leipzig and 90 kilometers (56 miles) southwest of Berlin, Stadtwerke Lutherstadt Wittenberg was founded in 1991 with a small CHP plant and just a few district heating customers. Today, Stadtwerke Lutherstadt Wittenberg is a modern combination utility supplying clean power 365 days a year to around 41,000 households and environmentally friendly heat to 21,000 homes.
“Through the modernized district heating plant, we are doing our part to help meet Germany’s goals of decarbonizing the energy system in Germany and meeting a minimum of 80% CO2 reduction by 2050,” highlights Hans-Joachim Herrmann.

New engines for Airbus Stade
The 3 gas gensets which have been delivered in 2007 (see special applications), were scheduled to have their first major overhaul this year. In order to minimize the period without redundancy for the inert gas production, the customer decided to buy new engines. The disturbance of the production should be as short as possible. There was a time frame of 8 weeks for the complete repowering project, exactly the maintenance-free period for the redundancy installation. We received the order for repowering of the 3 CHP-units from the engineering company MECOPLAN, which was assigned with the renovation of the complete installation.
Within 6 weeks, all old engines were stripped, prepared for their discharge, brought out together with their alternators, which have been overhauled during that period, too. New engines were partly dismantled, brought back with their alternators and finally put on the common base frame again.
Engines were completed and the gensets got recommissioned set by set. After a test run of several days -it was exactly 7 weeks after the project start- the complete installation was handed over to the customer again.
S&L delivers Waukesha gas engines for North Sea platform
In September 2013 S&L has been awarded to deliver two 16-cylinder VHP engines for the GDF-Suez platform E17a in the North Sea. This production platform is located about 160 km north-west from den Helder, just outside of the Dutch North Sea sector. Here, extracted field gas is cleaned and dried before it is supplied to the gas pipeline. As to date, two compressor sets do the job, driven by Caterpillar lean burn engines running on field gas.
The new Dutch Emission Legislation (BEMS), valid for new installations from 2010 and binding for all stationary gas engine plants from 2017, gave the impetus for the complete modernization of the platform compressor system. In general, lean-burn engines are not able to meet the stringent NOx levels (100mg/m³N) without installing a complex SCR technology. The logistical efforts for urea supply and disposal on a platform dropped this alternative very early. An overhaul of the lean burn engines was no longer useful in this context. Besides the new compressors, the revamping does also include two new stoichiometric gas engines. With their controlled catalytic converter (3-Way-Catalyst) these engines are capable to meet these stringent NOx emission limits.
The Dutch packager ConPackSys B.V. was entrusted with the construction of the new compressor package incorporating two compressor units on a common framework and they their selves placed the order about two engines at S&L for a planned delivery in March 2014.

E.ON Hanse Wärme commissions the "most efficient cogeneration plant in the North".
On 19 June 2013, E.ON Hanse Wärme GmbH was able to commission the Hanseatic City's first ultra-efficient cogeneration plant in Hamburg-Wandsbek, with Hamburg's Environment Minister Jutta Blankau and top executives from E.ON Hanse AG, GE Energy and GE Jenbacher present.
In the new modernised cogeneration plant (at the site where three GE Waukesha VHP engines were previously in operation for some 20 years) GE Jenbacher's first JMS424 module in Germany has been integrated into a new holistic design with condensation heat exchangers and a giant thermal pump. The cogeneration plant has now attained a 44% degree of electric efficiency and a total efficiency degree of about 100%.
S&L SOLUTIONS was in charge of integrating the cogeneration plant on assignment from GE Jenbacher. S&L's scope of supply and performance included dismantling the former plant, hot water and exhaust integration into the new JMS 424 module as well as integration of a smaller in-house requirement module, integration of the giant thermal pump, the ventilation system as well as project management for the entire project and construction management for the integration plant.
"We are very happy and proud that GE Jenbacher and E.ON Hanse Wärme have entrusted us with this task and confronted us with this challenge," says Stefan Schöne, manager of S&L Solutions. S&L project manager Raimund Meyer added: "The complexity of the entire system and the large number of plant components involved confronted us with quite a challenge. Thanks to the excellent cooperation with our client GE Jenbacher, the end customer E.ON Hanse Wärme and our sub-contractors and partners, we finally succeeded in commissioning the plant smoothly and on schedule."
Almost simultaneously, S&L Solutions was working on assignment from E.ON Hanse Wärme GmbH on a comparable project in Hamburg-Neuenfelde where a GE Jenbacher JMS 412 module constitutes the core of the plant. S&L SOLUTIONS has since 2005 successfully collaborated by now in over 30 cogeneration plant modernisation projects with E.ON Hanse Wärme GmbH and has successfully positioned itself in the promising cogeneration plant modernisation and repowering segment.
