TURKISH HOSPITALS SAVE €400,000 A YEAR IN ENERGY COSTS THROUGH CHP

ver the past decade, the Turkish healthcare infrastructure has been continually expanded with new hospitals. Healthcare services must be continually improved in order to enable the best possible patient care and health support. To cover the growing demand for energy, the Turkish MWM service and sales distributor İltekno İleri Teknoloji Mühendislik ve Ticaret A.Ş. has installed and commissioned two combined heat and power plants for two hospitals of the Memorial Healthcare Group. One of the plants is equipped with an MWM TCG 3016 V16 gas generator set, and the other with an MWM TCG 2020 V12 gas generator set. An MWM TCG 3016 V16 generator set with an output of 800 kWel was commissioned in the Ankara Çankaya Hospital. Featuring an output of 1,000 kWel, the second generator set was installed on the roof of the Memorial Bahçelievler Hospital. The Memorial Bahçelievler Hospital is one of the few hospitals worldwide which has been awarded LEED certification, a system of the United States Green Building Council for the rating of green buildings. The certification was granted in view of the high energy efficiency which is ensured and perpetuated by the 4 installed combined heat and power plant with a powerful MWM TCG 2020 V12 gas generator set. The CHP plant at Memorial Bahçelievler Istanbul was installed on the roof; this posed a major challenge in terms of installation, design and safety. Vibration and sound levels played an important role in selecting a supplier for the project. Thanks to an insulated container, very low sound levels of 65 dB have been achieved at a distance of 10 metres. The installation of the CHP plant for the Memorial Bahçelievler Hospital was performed by İltekno within only 36 hours. As the hospital is located on one of Istanbul’s arterial roads, the project had to be planned well. Thanks to the quick and efficient work of the service team, the installation was completed in only one-and-a-half days instead of the usual 4–5 days. Thanks to the two gas generator set-driven CHP plants at the two hospitals, the Memorial Healthcare Group saves about €400 thousand a year in power and heating costs. Additionally, due to the high efficiency of the MWM gas generator sets, carbon emissions are expected to be about 20 percent lower. The well-being of hospital patients depends on an uninterrupted power supply and a reliable emergency

power supply. To cope with the growing number of patients despite limited capacities and rising fixed costs, hospitals are forced to save expenses. This is achieved by increasing the efficiency in certain areas, e.g. in the field of energy management, which comprises the general power demand as well as a building’s heating and air-conditioning. An analysis of energy-related weaknesses can help reduce energy costs by up to 30 or 40 percent. Once the weaknesses that are not related to cogeneration have been analyzed and eliminated, the facility can start planning the rollout of an internal cogeneration power plant. The use of cogeneration with natural gas optimizes the energy supply and reduces emissions, thereby providing environmental benefits. Generator sets of the TCG 3016 series feature a unique combination of efficiency and robustness. One of the key benefits is their remarkable efficiency, which is unmatched in their class. In natural gas operation, for example, the electrical efficiency reaches up to 43.5 percent. In the cogeneration of power and heat an overall efficiency of up to
90 percent can be achieved. Moreover, a low oil consumption of less than 0.1 g/kWhel and long oil change intervals make the operation of the gas gensets more economical. The operating period until the general overhaul is 80,000 operating hours for natural gas applications. The MWM TCG 3020, successor model of the TCG 2020, generator set effectively balances efficiency and reliability. The genset delivers up to 18 percent more output than its predecessor, though its dimensions are almost the same. Additionally, the new model features long service intervals with up to 80,000 operating hours until the next general overhaul (if the gas quality is high) and a total efficiency of more than 87 percent (with natural gas). Owing to their high reliability and profitability, the TCG 3020 generator sets with an output of 1,380 to 2,300 kWel are ready for the challenges of Industry 4.0. Thanks to the use of the digital power plant control TPEM (Total Plant & Energy Management), the gas engines are able to reach their full performance for maximum plant availability, capacity, and usability. www.mwm.net WORLDWIDE INDEPENDENT POWER
