Hamburg, December 15, 2006: The Hamburg-based voltwerk AG, a leading specialist in project development and structured financing for renewable energies will operate under the name EPURON GmbH from January 1, 2007.

Over the past twelve months, EPURON has made huge strides in achieving sustained company growth. Thanks to the diversification in photovoltaics, bioenergy, wind energy and solar thermal power plants, coupled with marked expansion across foreign markets, business has been strikingly dynamic. With its new company name, EPURON is a testimony to the company's international strategy. Before, voltwerk was a leading provider of solar funds on a domestic scale. Today, the company is a global supplier of professional project developments encompassing all technologies. Furthermore, EPURON offers its customers attractive investment opportunities. Commenting on the re-branding, Nikolaus Krane— Managing Director of EPURON and a member of the Management Board at Conergy AG, said, "In renaming the company to the internationally more identifiable EPURON, we are highlighting our ambition to become the leading global provider of project development and financing in the renewable energy sector." EPURON currently has ten subsidiaries in eight countries. Preparations are already in place to expand into additional foreign markets.

Building on the success of the voltwerk brand, EPURON delivers attractive investments in renewable energies. "Our new claim — Power for Portfolios — signals our Return-on-Investment oriented policy for the benefit of our customers," explains Joachim Mueller, Financial Managing Director at EPURON. The company's customer base includes both institutional and private investors, whereby the proportion of institutional investors is already growing at a significant rate. All investors profit from: substantially increased project volumes, growing preferences for international project locations and technological diversity. This enables EPURON to put together attractive investment packages.

The company name reflects the expansion into other technologies. "We are no longer just active on the photovoltaic market," points out Thomas-Tim Saevecke, Managing Director, whose areas of responsibility include large-scale solar projects. "We also operate successfully in other key renewable energy sectors. Our new name perfectly symbolises these changes. We are very excited that the success of our company will continue under the name EPURON."
