Mainstream and Actis JV, Aela Energía wins contracts to build USD860 million of wind power projects in Chile

Aela Energía, the Chilean joint venture between Actis and Mainstream Renewable Power was today awarded Power Purchase Agreements (PPA) for the supply of renewable energy from five wind farms in Chile with a combined generation capacity of 343 megawatts.

The agreements were awarded under a competitive tendering process run by the National Energy Commission (Comisi?n Nacional de Energ?a). With a combined investment value of approximately USD860 million, four of the facilities are expected to reach financial close during 2015 and commence construction shortly after.  One of the facilities, the Negrete Wind Farm has been in operation since early 2014.


The PPAs, which will supply 26 Chilean distribution companies across the country, are for a term of 15 years and will power approximately 440,000 households annually. In 2013 Mainstream and global pan-emerging market investor Actis announced a joint venture to deliver 600 megawatts of wind and solar projects into construction and operation in Chile by 2016. The joint venture company Aela Energía is 40% owned by Mainstream and 60% by Actis. In addition to developing the projects, Mainstream will manage their construction and operation on behalf of the joint venture.

Commenting on the awards Mainstream’s Barry Lynch, Managing Director Onshore Procurement, Construction and Operations said: “Today is a very significant day for the Aela Energia, the Mainstream and Actis joint venture in Chile, and really puts it on the map as one of the leading renewable energy companies in the market. It is the first time PPAs of this magnitude have been awarded in Chile for renewable energy generation. Mainstream looks forward to managing this very ambitious construction programme once the projects reach financial close next year.”

Lucy Heintz, Head of renewable energy at Actis commented: “Winning these five projects is a huge achievement, with this we are well on the way to building Chile’s leading supplier of competitive renewable power. Actis sees wind power as a great solution for the emerging markets, in locations where optimal wind resources exist, we are looking forward to taking the next steps to deliver these projects into operation.”

Sergio del Campo, CEO of Aela Energia stated that “This award of contracts with Electricity Distributors allows us to realise five wind projects in the Central Interconnected System, thereby achieving an installed capacity of 343 megawatts and a total annual production of 1,140 gigawatt hours. The total investment required to comply with these contracts is around $860 million USD.  This commitment of Aela Energia is undoubtedly an important contribution to meeting the demand and price competitiveness of energy for the benefit of households in our country.”

  1. Negrete Wind Farm (33 megawatts) located in the Bio Bio region, has been in operation since early 2014.
  2. Alena Wind Farm (44 megawatts) located in the Bio Bio region.
