An SCR system cleans the exhaust from the diesel engines so that their emission levels remain well below the limits demanded by the German TA Luft clean air regulations. Control energy MEMO Olaf Dempewolf installed and commissioned the gensets in Fulda. Using a special remote access system he can not only monitor the plant on site but also from the office in Friedrichshafen. The expansion of renewable energies has brought with it greater fluctuations in the power grid because the wind is not always blowing and there is less sun on some days than on others. Despite that, the power grids in Europe hardly ever fail. Why is that? First of all, the electricity suppliers are obliged to submit accurate predictions of the amounts they will generate so that infeed to the grid can be planned as precisely as possible and the normal frequency of 50Hz can be maintained. But what happens if electricity consumption suddenly rises despite the most careful planning? That is when control power is called on to avert grid failure. This reserve supply balances out the fluctuations in the grid within a matter of seconds (primary energy reserve), minutes (secondary energy reserve) or a quarter of an hour (tertiary energy reserve). ■ Primary reserve: energy supply has to be fully available within 30 seconds and remain on stream for a total of 15 minutes. ■ Secondary reserve: full reserve capacity has to be available within five minutes. ■ Tertiary reserve: this has to be available within 15 minutes to take over from the primary and secondary reserves. 62 I MTU Report 03/12

He was also impressed by the open and positive approach adopted by the team from MTU Onsite Energy. "We always regarded each other as equals in our discussions and developed our ideas jointly. That was how the suggestion came about to replace the two large gensets with six smaller ones and build a gallery floor to accommodate the SCR systems for exhaust gas aftertreatment.” Cleaner, faster, more economical He reported proudly how cleanly and efficiently the units run. “With the new engines we have reduced the particulate emissions to a sixth of what they were, nitrogen oxides to a quarter and carbon monoxide to half the previous level per kilowatt-hour generated, and even lowered fuel consumption by 10% at the same time,” he recounted. The reason for those impressive figures are the modern engines with commonrail fuel injection and controlled SCR catalytic converters. The latter clean the exhaust by injecting urea into it. In the catalytic converter, the urea reacts with the nitrogen oxides to form the hamrless substances water and nitrogen. “These generator sets are inside the air pollution limits by a long way,” he stated with conviction. And with the power plant being right in the town of Fulda, it goes without saying that the emission levels have to be as low as possible. Because of that inner city location, ÜWAG also paid particular attention to reducing noise emission. Special soundproof walls allow almost no sound at all to escape to the outside when the engines are starting up and running. system installed. It allows the specialists at MTU Onsite Energy in Friedrichshafen to access the gensets and other components of the plant remotely and give advice on how to prevent or rectify faults. “Something special” The first three of six gensets went into operation in the power plant on December 23, 2011. Sven Kunkel remembers the period just before then very well. He and the whole team were under extreme pressure. Especially because at that time the plant had to be kept running constantly at 75%. “We were contractually obliged to supply electricity, we couldn’t shut down.” It was not until September 2012, when the local authorities in Fulda celebrated the inauguration of the power plant that Kunkel was finally able to relax. "The flexibility of this power plant meets the demands of the current market perfectly. It really is something special for a local authority supplier to have something like this," recalls the electrical engineer who is now also a diesel engine specialist.

That is something that will be happening more frequently in the coming weeks. It is in the winter when the weather is cold that the demand for electricity increases. “In the run-up to Christmas, everyone is baking,” said Sven Kunkel. “And apart from that, it’s cold outside, the days are short, and businesses are working at full tilt to get the jobs finished before the end of the financial year,” he added. As at any other time of year, reliable generators are a must in this period. For that reason ÜWAG has had a special remote diagnosis MTU Report 03/12 I 63
