Mainstream Renewable Power Successfully Completes the Final Phase of c.US$1.8 billion Wind and Solar Financing Deal in Chile

DUBLIN and SANTIAGO, Chile, July 1, 2021 /PRNewswire/ — Global wind and solar company, Mainstream Renewable Power (“Mainstream” or “The Company”), has achieved financial close for the third and final phase of its “Andes Renovables” wind and solar platform in Chile. The c. US$182 million in debt raised will be used to build the “Copihue” phase which consists of one wind farm, named Camán, located in central Chile.

The project, which will commence operations in 2022, initially had an installed capacity of 100 MW but has since increased to 148.5 MW following the signing of an additional long-term, bilateral Power Purchase Agreement (PPA) with a strategic partner.

The senior debt financing comes from KfW IPEX-Bank, DNB, CaixaBank and the VAT financing comes from Scotiabank Chile.

With the financial close announced today, Mainstream completes an investment of more than US$1.8 billion to build its entire Andes Renovables platform, which is expected to be fully operational by 2022 and will provide around 20% of power for regulated customers in Chile using renewable energy.  

Sacyr will be the Balance of Plant contractor for the Camán wind farm and they will carry out the electrical connection works. The main transformer will be supplied by ABB.    

Mary Quaney, Mainstream’s Group Chief Executive said:

“Net zero commitments across the world require systemic decarbonisation of power – our presence and work with partners in both mature and emerging markets demonstrates the scalability and success of our project development model to support this transition.

“Andes Renovables is one of the largest renewable energy platforms in Latin Americawhich will have an installed capacity of 1.35 GW of clean energy, generating around 3,100 jobs during its construction.

“It showcases our industry-leading expertise in structuring hybrid projects with the combination of ten wind and solar generation profiles in order to meet our commitments to deliver firm power at scale over a twenty-year period.

“It reflects our commitment to, and experience in Chile, which is one of the world’s most progressive renewable energy markets, and further solidifies our leadership position in-country, where we will soon be supplying the equivalent of one in five Chilean homes with power from our facilities.”

Manuel Tagle, Mainstream’s General Manager for Latin America said: 

“Andes Renovables will power the equivalent of more than 1.7 million Chilean homes and avoid the emission of more than 1.6 million tonnes of CO2 per annum, the same as that produced by approximately 350,000 cars each year. The ten wind and solar farms that make up the platform are located between the regions of Antofagasta and Los Lagos. It is precisely this geographical and technological diversification that will allow for a more secure and constant electricity supply.

“We are pleased to have increased the Copihue portfolio size by 50% by adding a bilateral PPA in addition to the existing regulated PPA, which demonstrates our standing in the market. 

“And it doesn’t stop there. We are using our platform in renewables and experience as a market leader to pioneer new developments in emerging technologies to complement existing capacity and ensure we are on the cutting edge of cleantech. In parallel to the Andes Renovables platform we are also investing in a new large-scale renewable platform, Nazca Renovables, and in the last few months we have signed four new energy supply contracts with private customers. We look forward to sharing more updates on both portfolios as they progress through development.”

About Mainstream

Mainstream Renewable Power is a leading pure-play renewable energy company with a global footprint. The company is focused on expanding its high-quality pipeline of more than 13 Gigawatts (GW) of wind and solar assets across Latin America, Africa, Asia Pacific as well as the global offshore wind sector. In May 2021, it closed an agreement for Aker Horizons to take a 75% equity stake in the company, enabling Mainstream to accelerate its global expansion plan to bring 5.5 GW of assets to financial close by 2023 ahead of a planned IPO.

Mainstream has delivered more than 6.5 GW of wind and solar assets to financial close, and currently has over 1.4 GW (net) in construction across Latin America and Africa. In Chile, Mainstream’s wholly-owned 1.35 GW of fully contracted wind and solar assets are on track to reach commercial operation from 2021. In Africa, the company has delivered 842 MW of wind and solar assets into commercial operation in South Africa, and further, through its Lekela Power joint venture has 410 MW of wind assets in construction in Senegal and Egypt.

Mainstream is the most successful independent developer of offshore wind at scale globally.  It has successfully consented Hornsea One (1.2 GW), the largest operational offshore wind plant in the world today; and developed the Hornsea 2 project (1.4 GW)  before selling these projects and the entire Zone in 2015. Overall, it has developed and later divested projects representing 22% of the UK’s offshore wind capacity either in operation or under construction.  Mainstream fully consented the Neart na Gaoithe offshore wind project in Scotland, 450 MW, currently under construction. Mainstream’s Soc Trang 1.4 GW offshore wind development in Vietnam is one of South East Asia’s largest renewable energy developments.

Mainstream has raised more than EUR3.0bn in project finance to date and employs more than 340 staff across five continents.
