Green Electricity Close to Production Site

In physical terms, the Vestas rotor-blade plant in Lauchhammer gets its electricity from an on-site biomethane power plant as well as from a nearby wind turbine. Economically, the power-supply model is considerably more complex.

Less Carbon Conversion Means More Biomethane

The standard production processes of bioenergy sources can be greatly simplified using a new procedure. Scientists from Leipzig, Bremen and Karlsruhe are researching the biological and technical requirements for it. February 6, 2012

Power-exchange price more consistent with green electricity

Solar and wind power are naturally quite irregular in terms of production and supply to the grid. The Epex Spot power exchange has coped with these fluctuations in supply rather well over the last year and a half. 07/2011

Solartrabi_kleinScientists have presented a concept of how German energy supply can be wholly converted to renewable energy by the year 2050. It’s really a matter of political decision-making, said Wolfgang Eberhardt, managing director at the Helmholtz Center for Materials and Energy. 10/2010

Könnern kleinGerman scientists have come up with a procedure for storing surplus wind and solar electricity as biomethane. The upgrading of biogas to natural-gas quality is making particular headway in Germany, Sweden and Switzerland. Yet the basic parameters still need to be set for the international transport and trade of biomethane. 04/2010

Könnern kleinIn Germany, some 4,000 plants produce biogas which is used to generate electricity. The latest trend is for plants to convert biogas into biomethane, which is then fed into the gas grid. By 2020, some 6% of the gas that flows through the German grid must be from renewable sources. 07/2009

Control room smallGerman gas providers coped remarkebly well with the supply disruption in January. They even managed to supply extra gas to hard-hit customers in Eastern Europe. Even so the companies are expanding their storage capabilities and looking for alternative supply routes. 02/2009

signet_kleinScientists, plant manufacturers and module producers in Saxony are working on new technologies that can be used to produce solar electricity more cost-effectively. The goal is to bring the price down to match that of conventionally generated electricity within the next few years. 01/2009

solarfassade_kleinMore and more solar technology companies are establishing themselves in the eastern German state of Saxony. The conditions in the state provide a solid basis for strong growth and the further development of their technologies. 01/2009

vngebude_kleinEast German gas company VNG Verbundnetz Gas has managed to remain independent since the transition to a market economy in 1990. With major shareholder EWE, based in northwestern Germany, now trying to take control, the board and other shareholders are fighting back. 12/2008

dr. hans-bernd menzel klein - foto bodo tiedemannEuropean Energy Exchange (EEX) in Leipzig is working on an alliance with other European energy exchanges. EEX has established a joint operation for spot market trading with Powernext in Paris. Belpex in Belgium and the Dutch exchange APX may also join in and there are talks with other exchanges. Dr. Hans-Bernd Menzel, chief executive of EEX: ‘We have then already got as far as the Pyrenees.’ 11/2008

eex klein - foto bodo tiedemannThe interlinking of the European Energy Exchange in Leipzig and Powernext in Paris was a major step in the consolidation of European energy exchanges. Many other moves are being made, but challenges in market coupling will have to be resolved before trading markets can become truly integrated. 11/2008
