New geothermal project in Rülzheim

HotRock has signed an agreement with the renewable energies engineering subsidiary of Pfalzwerke on a new geothermal project. BESTEC GmbH, as the general contractor, will carry out two deep drillings in over 3000 m depth and create a water circuit. HotRock and BESTEC already cooperated successfully in the geothermal project in Insheim. There, the subsurface works have already been successfully completed, and a geothermal power plant is expected to commence operations in 2011. The project in Rülzheim is due to begin immediately, with the same team. The drilling company will again be Jaslo Polska, with whom both partners have worked in the past. HotRock Engineering GmbH will carry out the planning and supervision. HotRock plans to build a geothermal electricity plant with ca. 5 MW capacity. In addition, it expects to make use of the heat generated as well, as the town of Rülzheim has a heating network. The contractual partners have already begun preparations. Managing director of HotRock Engineering GmbH, Dr. Christian Hecht, expects drilling will begin in October 2009. HotRock owner and CEO Werner Kindermann: „We are excited about the new project and confident with our seasoned team. Based on the exploration results, we are optimistic that we will find similar or even better conditions than in Insheim.” The project in Rülzheim is due to form the cornerstone of a HotRock portfolio of power plants; further projects are in preparation.

HotRock sells HotRock Erdwärmekraftwerke Insheim to PFALZWERKE

The HotRock Group sold HotRock Erdwärmekraftwerke Insheim GmbH & Co KG to Pfalzwerke Projektbeteiligungsgesellschaft mbH on November 13, 2008. The parties agreed to keep the purchase price confidential.

HotRock succeeded in finding a water reservoir in 3,600 m depth in Insheim. First measurements confirmed that the water has a temperature of more than 155°C and is sufficient for a geothermal power plant.

A number of potential investors had expressed vivid interest in the project. HotRock decided on the local energy supplier PFALZWERKE as a strategic partner. HotRock will continue to expand its market position as a specialist in geothermics through further projects, to commence shortly among others with the PFALZWERKE affiliate BESTEC GmbH as its operative partner.

HotRock owner and CEO Werner Kindermann: „We are extremely pleased with the good results in Insheim and are looking forward to the future cooperation with PFALZWERKE. The next joint project with the successful team BESTEC and Jas?o is already in preparation.”

Drilling commenced June 2 in Insheim

HotRock has completed set-up and commenced drilling at its Insheim site, where it intends to build a geothermal power plant within the next two years. The site was chosen on the basis of the group’s own extensive 2D-seismic reflection surveys. Along with the geological characteristics, the site also excellently fulfils infrastructure requirements for a geothermal project.

The geothermal power plant is planned to be run on a doublet system (injector well, producer well). The first deviated well will explore the reservoir. If sufficient water is found, the second well will be drilled, with a distance of more than 1,000 m between the end points of both drillings. Once the doublet is hydraulically connected below ground, the primary circulation system above ground will be completed, and the obtainable electrical capacity and the capacity of the power plant will determined in circulation tests.

HotRock begins new geothermal project

Drilling for hot water has again commenced in the Upper Rhine Graben. HotRock Holding, Karlsruhe gave the go-ahead for the beginning of deep drilling works in Insheim today. Adjacent to the autobahn A 65, a new geothermal power plant with two deep drillings of more than 3000 m will be constructed. The general contractor Bestec, Kandel and the drilling company Jaslo Polska already both contributed to the successful completion of the geothermal power plant in Landau.

HotRock Engineering, together with Marsh, has created an insurance concept which for the first time also covers the finding risk. Insheim is the first project in the Upper Rhine Graben to be carried out with this comprehensive insurance. All players are convinced that the drilling will be successful and that hot water will be found soon in Insheim. With the Insheim project, HotRock again demonstrates its leading role in the development of deep geothermics in the Upper Rhine Graben. This hottest area of Germany offers a huge potential for the future. Other projects by HotRock Holding are already in planning and shortly before implementation.
