Large Scale Renewable Energy Projects

Large Scale Renewable

Adenco established a renewable energy division for which we have large scale plans and dreams.

South Africa is addressing a number of challenges in its energy sector, including the need to meet growing demand, as well as diversifying its energy mix away from coal, which accounts for 75% of installed capacity.

The South African Government has decided that the renewable energy sector should have a key role in its medium to long-term energy planning program. The government's Integrated Resource Program (IRP) 2010, a 20-year national energy plan, foresees a big increase in the country's energy capacity and a gradual introduction of renewable energy sources until they account for 30% of electricity generated in South Africa by 2030.

De Aar 1 and De Aar 2 Wind Farms

Adenco Construction was the electrical contractor on De Aar 1 Maanhaarberg a 90 MW, 67 tower wind farm and on De Aar 2 North a 140MW, 96 tower wind farm in the Northern Cape South Africa for EPC, Longyuan Engineering.

Adenco completed all the external electrical connections to the 163 wind turbine generators; the IPP Step Up Substations; Eskom Substations.

The project entailed:

Maanhaarberg :

  • 60 km of 33kV overhead line with OPGW & ADSS
  • 67 x 1.8 MVA transformers
  • 100 MVA IPP & Eskom substation

De Aar North:

  • 100 km of 33kV overhead line with OPGW & ADSS
  • 96 x 1.8 MVA transformers
  • 140 MVA IPP & Eskom substation

The wind farms were located on the Maanhaarberg Mountains. These projects were the first overhead line installation on a wind farm in South Africa due to the mountainous soil and undulating conditions. Work was completed in extreme weather conditions of -10 to 45 degrees.

  • Built a 132 kV Substation
  • Built 12 km of 11kV overhead lines
