Yves Lebbe, a cogeneration facilitator at Brussels Capital-Region, states: “In 2005 we had 15 cogeneration units, now we have more than 70 cogeneration installations in our region. These projects deliver successful results in the private and in the public building sectors.”
Such an installation is placed in the prestigious Conrad Hotel, where a combined heat and power (CHP) engine produces both electricity and heat from natural gas. Every year 2294 MWhe of electricity and 3178 MWhth of heat is produced by this engine. Compared to the old energy provision of the hotel, the new CHP engine delivers a direct energy saving of 13%. On annual basis CO2 emissions are expected to go down by 317 tonnes, which means a reduction of 18% in the overall CO2 emissions of the hotel.
Installing the CHP engine involved an up-front investment of €412.500, which pays itself back within 3 to 4 years through an estimated 25% annual reduction in energy costs. The up-front investment and maintenance of the installation is taken care of by a private company.
The Brussels Capital-Region has been a member of Energy Cities since 1998 and is currently vice-president of its board of directors.
