„We are looking forward to invest also in the future in more wind farm
projects of e.n.o. energy GmbH with wind turbines of e.n.o. energy
systems GmbH.“
(2009)
„The wind turbine of the type e.n.o. 82 and its technology inside has
been tested by experts like Garrad Hassan. A financing of e.n.o. 82 is
considered favourably on the basis of this inspection.“
(2009)
„In Summary, the e.n.o. 82 includes many concepts and components
which are commonly used by modern, megawatt class turbines.
The overall concept has proven reliable in these turbines.“
(2009)
„… herewith, we confirm that the quality of the existing insurance
concept of e.n.o. energy systems GmbH is above the market
standards…“
(Marsh Düsseldorf, 2009)
