Many years of experience in traditional power plants allowed SAET to know the problems of interconnecting power plants to renewables on the national grid. The electrical substation provided with complete turnkey civil works allowed SAET to enter the renewable energy sector.
Perspective of customer service delivery has been completed in some cases with civil works for wind or solar farms, with the earth system and telecommunications connections with medium voltage coming to a complete BOP (Balance of Plant ) and, in some cases of solar farms, even with the provision of electrical panels and control.

Due to this path, SAET has built its role in renewable
- For wind power projects in terms of BOP contractor or consortium with the manufacturer of wind generators;
- For photovoltaic projects as EPC Contractor or Contractor BOP;
- For projects such as biomass BOP Contractor with SCADA supervision;
- For other renewable energy projects (solar thermal, geothermal, hydro and minihydro) SAET is available in various forms of collaboration.

The SCADA system supervision that SAET provides both for management and for supervision of electrical protection (IEC 61850) is used as a shortcut
for the service remotely.
