South African solar power plant wins PFI solar deal of the year
The government's Renewable Energy Independent Power Producer
Procurement Programme (REIPPP) is rapidly contributing to South
Africa's growth as one of the fastest growing renewable energy sec-
tors in the world.The Minister of Energy has been determined that
3 725 megawatts (MW) of renewable energy sources is required to
ensure the continued uninterrupted supply of electricity.
According to Hartmut Winkler, Professor of Physics at the Uni-
versity of Johannesburg, the REIPPPP contributed to over 6 000
MW to date. It is envisioned that this figure should reach 9 600 MW
of solar power capacity by 2030. All completed solar power plants
form part of South Africa's electricity supply and are fully linked to
the Eskom power grid. Currently, solar power already contributes
to more than 1 MW onto the grid on a sunny day.
The Ilanga 1 CSP Project recently won the 2015 Project Finance
International (PFI) solar deal of the year.The award ceremony took
place on 3 February 2016 in London.The plant is located about 30
kilometres east of Upington and forms part of the Karoshoek Solar
Thermal Park. Ilanga 1 is a 100 MW parabolic trough plant with a
thermal energy storage system.
Apart from the significant job-creating opportunities, the project
promises to deliver over half a billion Rand annually to socio-eco-
nomic development over a 20 year period.The surrounding areas
will benefit from these socio-economic development initiatives.
Jen Stolp, partner in Baker & McKenzie's banking and finance
department, acted as lender counsel. Lenders of the project included
Development Bank of Southern Africa (DBSA), the Public Invest-
ment Company (PIC), the Industrial Development Corporation (IDC),
Nedbank, Investec, Standard Bank and ABSA.
"The Ilanga 1 CSP Project aligns perfectly with ABSA's CSI initia-
tives aimed at enhancing business relevance, sustainability and
social upliftment. It is great to see projects geared at creating a bet-
ter future recognized at the PFI awards", said Shaun Moodley, Vice
President Banking-Resource and Project Finance at ABSA Capital,
regarding ABSA's involvement in the project.
Emile Malan, Principal: Energy at Nedbank, said: "Nedbank is
committed to green funding and supporting sustainability initiatives,
and we're proud to be part of the Ilanga 1 project. It is projects like
these that help us build on our long history of promoting environ-
mental responsibility."

• To realise proper design you need to
understand the parameters defining the
system.
• Mechanical parameters can be calculated
and matched to motor and drive systems.
• Matching load and motor rotor inertia is
a key component in the design described.
