• The 100 MW power plant based on parabolic trough technology will supply 179,000 homes

The Kathu Solar Park (South Africa) constructed by ACCIONA Industrial and SENER came into commercial on 30 January. With an installed capacity of 100 MW, it will allow clean energy to be supplied to 179,000 homes in the Northern Cape region (northern South Africa) and prevent the emission of six million tonnes of CO2 into the atmosphere over the next 20 years.

The plant incorporates SENERTrough®-2 parabolic trough collectors and a molten salt storage system that enables heat from the solar park to be stored and electricity to be generated in the absence of solar radiation. This molten salt storage system, which provides up to 5 hours of power generation, extends the operational capacity of the plant after sundown and on cloudy days.

Roberto Felipe, Director of Operations and Production at ACCIONA Industrial, stated: 'At ACCIONA we are committed to renewable energies, and in particular to CSP energy. The execution of the Kathu Solar Park plant has been a success thanks to the excellent team involved in the project, but also for the impact it has had on the economy and population in the Province of the Northern Cape in South Africa. This has been made possible thanks to the excellent relationship with local administrations and businesses, and with Kathu Solar Park, our client. In addition, this plant becomes our second project in the region along with the Bokpoort solar thermal plant, which consolidates us in the renewable energy market in the country'.

Siyabonga Mbanjwa, Regional Managing Director of SENER Southern Africa stated: “with the completion of Kathu Solar Park, we show our firm commitment to the development of a renewable energy industry in South Africa. Concentrated Solar Power in particular as a viable alternative to traditional baseload sources of energy, has a demonstrated alignment with South Africa’s national agenda of achieving inclusive growth that includes job-creating, manufacturing, construction and rural development. Reaching commercial operation at Kathu means that the energy supply to the local community is secure and demand is well managed while contributing to mitigate the effects of climate change”.

The project is part of the South African Government’s Integrated Resource Programme (IRP) 2010. This plan aims to increase the country’s power generation capacity to 86.8 GW by 2030, of which 24% will be renewable.

Kathu Solar Park was one of the projects awarded during bid window 3.5 of the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) by the South African Department of Energy (DoE).

The joint venture between ACCIONA Industrial and SENER Industrial was appointed by the shareholders, which is led by ENGIE, including a group of South African investors comprising SIOC Community Development Trust, Investec Bank, Lereko Metier Sustainable Capital Fund, its co-investors FMO, the Dutch development bank and DEG, the German investment and development company and the Public Investment Corporation to provide the engineering, procurement and construction services on the project.

Construction began in May 2016 and has created 1,700 jobs in peak June 2018. The Kathu solar thermal power project has also contributed to the economic development of the region by contracting local suppliers and through the KSP Social Economic Development program and the Kelebogile Foundation, which have invested in and significantly boosted community development in the John Taolo Gaetsewe District Municipality.

This is the second solar thermal power project jointly developed by the two companies in South Africa. The first was the 50 MW Bokpoort plant (Upington), officially opened in late 2016, for which they were also part of the construction consortium.

ACCIONA Industrial has extensive experience of developing turnkey renewable projects for electricity generation facilities based on wind, solar thermal and photovoltaic technology. Its most significant projects include the Cerro Dominador project (110 MW), the first solar thermal energy plant in Latin America currently under construction in the Atacama Desert in Chile; the Noor 1 parabolic trough solar thermal power plant (160 MW) in Morocco; the Mohammed bin Rashid Al Maktoum Solar Park (Stage III) (800 MW), currently under construction in Dubai (UAE); and the Mesa de la Paz Wind Farm (306 MW) in Mexico. 

SENER leads the global solar thermal-electric power market, both in terms of the number of projects in its portfolio and its own technological solutions. SENER has participated in 29 plants in total, most of them turnkey projects, in Spain, the United States, South Africa (Bokpoort , Kathu and Ilanga-1 solar thermal power plants) and Morocco (Noor I and Noor II parabolic trough solar thermal power plants and Noor III central tower power plant), representing over 2,000 MW of installed capacity and a saving in excess of one million tonnes per year of CO2.
