Nordhausen: The way to a climate friendly local strategyDocument Transcript
man City o Nordhausen and its way to aThe Germ ofmore sust tainable an climate friendly loc strategy nd calAs early a the beg as ginning of the 1990s the town of s, nNordhaus sen took its first succ s cessful ste toward a eps dsmodern and gu uaranteed energy supply. InSeptembe 1992 the Nord er dhausen t town cou uncilratified a an energy supply concept y which was wdeveloped under the aegis of the then e d e environmentaldepartment and which established the f framework for kthe restru ucturing of energy supply in our town. In f sdoing s so, emph hasis wa as place ed on thedecentrali isation of the old district-hea d ating syste em.The old ramshack coal-fired power station was kle r wdisconnec cted and th focus of energy pr he f roduction was wturned to owards m modern de ecentralised product d tionstructures s.In the ye ear 1994, 3 highly efficient natural gas- y gpowered combined heat and power stations plus d pnewly str ructured conduction were brought into nsoperation, at an inv vestment cost of 35 m million DM by Mthe No ordhausen Energieversorgu ung Gm mbH(Nordhaus Power Supplier Ltd), which had already sen r h Impreessions of the p participatory clim mate strate developmen egy nt. ablished on 26th Mar 1992 w municbeen esta n rch with cipalparticipation. This m meant that district en t nergy supp to ca. 9,800 hou ply useholds could besustainab guaranteed. blyIn the tow of Nordhausen, electricity g eneration takes plac accordin to the principle wn ce ng pof combin ned heat and powe (CHP) in three highly effi er icient CHP power stations P spossessin an effic ng ciency of ca. 90%. T c These com mbined hea and pow facilitie meet at wer esapproxima ately 40% of Nordha ausen’s en nergy requ uirements. Natural g as is used as an denergy so ource. The heat occu uring during the conv g version of the gas is conducted over a t dheat exch hanger and fed into the distric heating grid. 81.3 of hea provision takes d ct 3% atplace usin CHP pro ng ocesses.
In the year 1995 the town council gave the administration a mandate to prepare adistrict heating statute, which has now been in force since 1997 and was updated in2010, because of the comprehensive legal regulations on obtaining renewable energy,such as the KWK-Gewetz (CHP law), the EEG (German renewable energy law), andthe EEWärmeG.At the same time the existing district energy precedence regions were examined andadjusted to see if consolidation was possible, as well as sensible – i.e. practical andeconomic – expansion.Furthermore, it was examined whether public buildings could be incorporated into thedistrict heating supply.Today we enjoy the benefits of the existing grid structures with a high proportion of heatsupply through highly efficient combined heat and power together with a domesticcurrent production of ca. 40%. Electricity production in the CHP facilities also makes asignificant contribution to the positive CO2 balance of the entire townThe town of Nordhausen’s renewable self-supply rate in the electricity sector amounted,in the year 2009, to a production of ca. 29 million kWh of electricity (from photovoltaic,wind, water and biomass) out of an annual consumption of ca. 300 million kWh ofelectricity, therefore ca. 9%.Of this: 6 million kWh from solar electricity installations 7 million kWh from wind power installations 0.2 million kWh from water power installations 16 million kWh from biomass power installations * Source: http://www.energymap.info/energieregionen.htmlWithin the framework of the integrated town development concept, the energyinfrastructure will now also be studied. Through the development of an integratedclimate protection concept, including a heat use sub-concept, the town of Nordhausenspotential for using renewable energy, both in urban and rural regions, will be examinedand evaluated. For this purpose the town of Nordhausen was able to acquire specialistsupport from competent partners, the Nordhausen Fachhochschule (NordhausenVocational College), the Graw Planungsbüro and ICLEI, and the international council forlocal environmental initiatives. The process of creating the climate protection conceptwill examine how options for renewable energy production can be deployed effectivelyin urban regions, in order to ensure an environmentally sound and affordable energy
supply locally. At the same time the process will examine how aims for a sustainableclimate protection policy can be implemented at local level bearing in mind regionaladded value, and how measures for climate protection can be encouraged locally.At the conclusion a catalogue with concrete measures and projects, as well asrecommendations for action up to 2050 will be presented, including the associatedCO2 reduction potential, which will be implemented together with the partners involved,in order to raise the proportion of renewable energy in the town of Nordhausen.Furthermore, the creation of an energy and climate pass should serve as a regulativeinstrument of time- and cost-efficient reduction of greenhouse gases, making theproportion of renewable energy and the potential saving of greenhouse gases visible forthe entire town. With the energy and climate pass, a normative outline will be created,providing a basis for the energy modifications of the towns, and therefore forsustainable town development. It is anticipated that the climate protection concept willbe passed by resolution of the Nordhausen town council in the second half of the year2012.Together with the municipal economy, the town of Nordhausen has created excellentprerequisites to enable us, in collaboration with all partners involved, to raise theproportion of renewable energy within our overall energy production step by step, alongthe path of self-sufficiency.In so doing, the town of Nordhausen not only plays its role in implementing theEuropean and national climate protection aims, but also the aims of the National TownDevelopment Policy, the EU Leipzig Charter for Sustainable Towns, and the LisbonStrategy for Growth and Employment.
