Geothermal projects announced in Germany
Drilling projects to discover possible sites for geothermal power plants are appearing throughout Germany. Five small plants are operational, and others will become operational in the coming years. Normally the power output of these installations in Germany does not exceed the 10megawatt MW capacity.
In Bavaria, Geoenergie Bayern GmbH is developing two projects. One potential site is located in the town of Utting, west of the Ammersee Lake in south Munich. Drilling works started this year in a 45squarekilometer area. The energy output of the plant, which should be operational by the end of 2012 is expected to be 10.4 MW.
Seismic measurements were taken in February for the second project being developed by Geoenergie Bayern. The 87squarekilometer testing field is located in the city of Kirchweidach in the eastern part of the Munich district. At almost 12,000 feet underground, rock formations contain hot water, which could be used to supply the city with heat and energy. Energy output is thought to be about 8 MW. The plant could be operational by 2014.
A third project by the German company was sold to the Munich public utility company Stadtwerke Muenchen. In Sauerlach, located in the south of the Munich district, a 5MW power station is planned. At more than 16,400 feet underground, the water is thought to be about 284 degrees Fahrenheit. The geothermal plant in Sauerlach is scheduled to be operational by 2011.
Potential regions for geothermal developments in Germany are the Molasse Basin in the south of Munich, the Upper Rhine Graben and the North German Plain. The largest geothermal power plant, with 38 MW of thermal capacity and 4 MW of energy output, was built with public finances in Unterhaching in the south of Munich. Other plants are operating in Landau 3 MW, RhinelandPalatinate, NeustadtGlewe 200 kW and MecklenburgWestern Pomerania.
The German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety assumes that the geothermal potential of Germany is about 321 billion kilowatthours per year.

Overturning statewide vote, Maine court energizes Hydro-Quebec's bid to export power
BANGOR - Maine's highest court on Tuesday breathed new life into a $1-billion US transmission line that aims to serve as conduit for Canadian hydropower, ruling that a statewide vote rebuking the project was unconstitutional.
The Supreme Judicial Court ruled that the retroactive nature of the referendum last year violated the project developer's constitutional rights, sending it back to a lower court for further proceedings.
The court did not rule in a separate case that focuses on a lease for a 1.6-kilometre portion of the proposed power line that crosses state land.
