Wörlen, who is the former head of the German Energy Agency’s renewable energy division and who now has her own consulting business, predicts that the renewable energy market in South Africa will grow.
However, growth is determined by policy schemes and, while there is demand from administrators, there are various conflicts and red tape that need to be resolved first, she notes.
Nevertheless, she says South Africa has been cautious with regard to solar and wind energy, but that it was a wise decision to drive energy efficiency and roll out solar water heaters.
“Now there is new excitement about the opportunities that renewable energies [provide],” she notes.
Wörlen says she is pleased that the South African government has developed the Renewable Energy Independent Power Producer Programme (REIPPP), which is aimed at integrating 3 725 MW of large-scale renewable energy capacity into them national power grid between 2014 and 2016.
She states that there are encouraging signs in South Africa, referring to the first round of power purchase agreements, which were signed last month, settling the first 100 MW on the contract side of the REIPPP.
“One should celebrate these interim successes. Although many people are disappointed with the pace of progress, they must understand that transformation is not necessarily fast. It is good that South Africa is moving forward. Its renewable community is growing every year,” Wörlen states.
Meanwhile, she points out that there are also many interesting opportunities for rooftop photovoltaic (PV) or other small-scale renewable energy projects, such as on-site generation at farms.
“The country cannot do everything at once and the process of implementing renewable projects at all scales simultaneously would require a lot of government capacity,” Wörlen states.
In Germany, the Parliament has mandated utilities to make the process very simple. A rooftop solar installation and the signing of power purchase agreements with the power utility can be completed in a few weeks, the record being eight days, while this process takes much longer in South Africa, owing to red tape and administrative requirements, she points out.
Solar PV systems are practical for South Africa, as they are easy to use, Wörlen states.
Further, she says that, if no red tape existed, the solar PV system could be installed in many places in the country and be connected to the national electricity grid.
Solar energy is a clean and sustainable energy source that contributes to job creation and the development of new technologies. It is also localised and can be used where it is produced.
Wörlen notes that regional planning with other countries in the Southern African Development Community is needed, not only to attract jobs in solar manufacturing but also to draw up a joint plan of how much capacity should be deployed in Southern Africa.
There is a minimum market size required for manufacturing jobs to become located in Southern Africa.
“Renewables are the only real growth branch of the energy industry and it is the only sector where costs will decrease,” she states.
“As technologies become more reliable, more manufacturing capacity is created for wind turbines and solar modules. So, we achieve economies of scale by manufacturing more turbines and we achieve economies of scope by having a professional service industry supporting this. The more standardised these technologies become, the less expensive they become,” Wörlen adds.
Further, she states that there is significant scale-up of renewable energy technologies around the globe, with more countries starting to manufacture and deploy renew- able energy technologies.
Most countries that have long-term renew- able energy commitments expect to fulfil a part of that from wind energy, she says.
Solar Market and Skills
“These individuals are not originally trained in the solar industry. But they have learned it over the years, during a pervasive, cultural change. This is one of the major job [creators]. Other countries have not understood this and still do not have the pervasive skills throughout the industry to implement a large number of projects,” she states.
Further, she hopes that more international exchange of renewable energy information and practical experiences will occur, so that those with experience in grid stability can assist in the even distribution of systems over regional areas and with the administrative handling and initial additional costs associated with this type of energy.
Wörlen delivered the keynote address at this year’s Clean Power Africa conference and expo in Cape Town last month.
She spoke about global best practices on renewable energy integration and highlighted that a stable regulatory environment is needed to encourage investment in renewable energy.
“The wave of deployment will be slow in the beginning, as few investors immediately delve into a new technology in a new country. Deploying renewables, or any innovation for that matter, will work better once the regulatory environment has increasingly quelled investment uncertainty among investors.
“This will lead not only to more investment, but also lower prices and costs for the resulting projects,” she says.
However, Wörlen says there needs to be a regular incremental adjustment of the regulatory framework because, as the technologies develop and become more competitive, the integration of increased power output from intermittent technology becomes more complicated and new regulatory detail is required.
Meanwhile, she says that consuming more energy is still a symptom of economic growth, and that renewable energy is plentiful and comparatively harmless. Renewable energy can help to allow for growth in a more sustainable manner than conventional energy sources.
“The industry will develop more of its own tools for renewables integration on a small and a large scale. Solar inverters that provide reactive power, virtual power plants and inte- grated storage systems are just the beginning. I expect a lot of technical innovation in this field, with a focus on systems and integration, rather than on just a solar cell or just a wind blade,” she concludes.
