Chile - award of Tenders (Oct 2015)
Cuel wind farm, Chile (33MW)
• Mainstream’s Chilean JV, Aela Energía won a tender from
Chile’s National Energy Commission to build and operate 265
megawatts of wind power.
• The 20-year contract will supply regulated customers in Chile’s
SIC electricity system starting from 2017.
• The tender saw thirty-one companies compete for the supply
of 1,200 gigawatt hours to unregulated customers in Chile. 65%
of the total allocation was awarded to Aela Energía.
• Wind and solar outbid fossil fuels on price – resulting in 100%
of the power contracted being awarded to wind and solar.
Bart Doyle, General Manager,
Mainstream Chile
“Mainstream is delighted to see that our investment over the past seven
years in Chile has culminated in this significant win for Aela Energía in
what has been a highly competitive tender process”.

Case study: SMart Wind (4,000MW)
SMart Wind was established as a joint venture between Mainstream Renewable Power
and Siemens Project Ventures in 2009 to bid in The Crown Estate’s Round 3 offshore wind
farm programme. Subsequently, it was awarded the 4GW Hornsea zone in 2010. The
Hornsea Zone has the potential to provide electricity to meet approximately 4% of all
electricity demand in the UK and power approximately 3 million homes. The total zone
area is 4,735km with water depths across the zone between 30 and 40m, with maximum
depths to 70m.
In February 2015, DONG Energy acquired Project One and following that, DONG Energy
acquired the remainder of the Zone on 21 August 2015.
www.smartwind.co.uk
A number of milestones have been met in the development of this zone including:
• Agreement for Lease from The Crown Estate signed in 2011.
• Award of Financial Investment Decision Enabling Contracts for Difference (CfD) in April 2014.
• Development Consent Order for 1.2GW granted by Secretary of State – Dec 2014.
• Project Two submitted to the UK Planning Inspectorate and expecting a decision by mid-2016.

Jeffreys Bay
The Jeffreys Bay wind farm was submitted to the South African Government’s Renewable
Energy Procurement Programme as part of a consortium (see below). The project was
awarded preferred bidder status by the Department under the first round of programme
and reached commercial operation on 15 May 2014.
The Jeffreys Bay wind farm is one of the first and largest wind farms in South Africa and will
assist in meeting the every-increasing demand for electricity in South Africa. At the peak of
construction, employment surged to some 650 on site. The wind farm will generate enough
electricity to power over 110,000 typical South African households.

The project is located in the Northern Cape and supplies the Eskom gridline with 85,458 MWh
per year – enough electricity to meet the needs of 20,000 average South African households.
Through enterprise development, the creation of procurement and employment opportunities
and the development of a local community trust, the solar park has invested in the
communities in its vicinity.

Case study: De Aar solar park
De Aar
The 50MW De Aar solar park was submitted to Round 1 of the South African Government’s
Renewable Energy Procurement Programme as part of a consortium. The project was
awarded preferred bidder status by the Department under the programme and reached
commercial operation date in early April, 2014. Each year the solar farm will generate
sufficient electrical energy to meet the needs of 20,000 average South African households.
During the construction period the project created hundreds of jobs and during the twenty
year operation of the solar plant approximately 20 long term jobs will be created to operate
and maintain the facility.

Case study: Cuel wind farm
Cuel
The Cuel wind farm is located 560kms south of Santiago, close to Los Ángeles city in the Bío Bío region of
Chile. Mainstream fully developed the project in association with local authorities, municipalities and the
community. Construction of all 22 turbines was completed Q1, 2014 and, in February 2014, the project
started to generate power. Aela Energía, the joint venture company between Mainstream and Actis is fully
responsible for the Cuel project and it is the first in its 600MW pipeline.
Mainstream will continue to operate and maintain the project on behalf of Aela Energía.

Case study: Carrickeeny wind farm
Carrickeeny
Carrickeeny wind farm is located in County Leitrim in the North West of Ireland. The wind farm
is Mainstream’s second project in Ireland. Mainstream took the project over at the late
development stage and following construction was sold to IKEA. Mainstream will continue to
operate and maintain the wind farm on behalf of IKEA for it’s 20 year lifespan.
The wind farm is connected to the Irish national grid in Manorhamilton substation via 10km of
overhead line. Annually the plant will avoid the release of 13,270 tons of CO2 from fossil fuel
power generation.

Case study: Knockaneden wind farm
Knockaneden
Supplier:
Mainstream entered the Irish wind market in 2011 with the acquisition of Caherciveen Wind
Limited which was developing the 9MW Knockaneden wind farm located in County Kerry in
South-West Ireland.
Mainstream managed the construction of the wind farm which consists of four Enercon
turbines. In January 2013, the Knockaneden wind farm reached commercial operation and it
is operated and maintained by Mainstream for Caherciveen Wind Limited.
A wind farm community fund was set up by Mainstream and is awarded each year to local
community groups and projects, particularly those with a focus on sustainability. The
community fund will be distributed for the lifetime of the project. Annually the plant will
avoid the release of 13,270 tons of CO2 from fossil fuel power generation.

Case study: Neart na Gaoithe
Supplier:
Neart na Gaoithe
The 450MW Neart na Gaoithe wind farm is being developed off the east coast of Scotland.
When built it will provide enough electricity to power the city of Edinburgh –
approximately 325,000 homes.
The project has reached a number of milestones including receipt of onshore consent from
East Lothian Council (June 2013) and Offshore consent from the Scottish Government
(October 2014). Also in 2014, new floating offshore wind measurement device completed
validation at the offshore wind farm.
Neart na Gaoithe was awarded a CfD by the UK government in February 2015 and is
expected to be generating electricity and fully commissioned by 2020.
