goals

ISO/IEC 17025:2005

An efficient and widespread use of renewable

energy sources in Greece, with a high penetration

rate in the country’s energy mix and a growing

importance in the citizens’ daily life.

A growing progress of renewables, ensuring a

more natural environment and improving living

standards and working conditions.

A gradual disengagement from oil dependency and

other polluting energy sources.

vision

mission

Participate and contribute in a decisive manner in

achieving our vision for Renewable Energy Sources

by developing and implementation efficient

methods of clean and environmentally friendly

energy production.

Participate in the effort to reduce greenhouse

gases emissions that aggravate global warming,

saving non-renewable resources and achieving the

national targets for the penetration of RES in the

country’s energy mix.

Spread the philosophy that we borrow the natural

resources of our planet from future generations

and must therefore manage them prudently and

wisely.

The lattice tower design was implemented

using CAD CAE technology.

Modelling design and assembly as well as

finite element analysis (FEA) techniques

were integrated within NX8 platform

(formerly known as Unigraphics).

Every part is verified and checked separately

and the whole structure has been certified

for euro code compliance.

This construction is made to withstand very

high winds with 10 minute average higher

than 50m/sec which leads to gusts over

80m/sec at the top of the mast.
