Large scale renewable energy power plants

The company's core activity is the development, design, construction, financing and operation of wind farm projects worldwide. With a portfolio of more than 4.5GW constructed and several thousand megawatts under construction and in development, RES continues to play a leading role in what is now the world's fastest growing energy sector. RES is also an independent power producer. They own and operate a growing portfolio of wind farms around the world, currently totalling over 550MW.
RES offers the installation of solar plants utilising either Photovoltaic power (PV) or Concentrated Solar Power (CSP) in North America and the Mediterranean region. We have the know-how, the resources and the project management capabilities needed to develop, construct and operate solar fields for large scale power generation connected to the grid.
RES has recently embarked on its first large-scale biomass power station development. The 100MW project in Northumberland in the UK will generate green electricity for homes and businesses, provide 'green collar' jobs and contribute to the regeneration of the area.
