Wind energy has been a buzzword in sustainable energy circles for decades.  Even though a lot of progress has been made, wind energy faces a number of obstacles: wind turbines create significant noise, they are not ideal for the urban environment, they generate vibration, and most significantly, wind power can be highly variable by virtue of its source, presenting a substantial challenge to incorporating large amounts of wind power into a grid system.  Nowhere is this last concern more relevant than in Israel, where a day’s significant winds can be followed by weeks of no movement.  To solve this problem, one Israeli company has developed a unique form of wind turbine which not only reduces vibration and noise production, but works effectively and efficiently in areas (around the world) which are plagued by inconsistent wind patterns.

SmartWind, established in 2009 by Andrey Kotler,  has developed the innovative “Vertical Axis Wind Turbine”. The technology, which introduces a form of “Active Flow Control” to the traditional wind power process, adapts turbines for operation in weak and irregular wind flow conditions, while guaranteeing high performance. In addition to significantly reduced noise and vibration, the company’s rotor technology provides the means to enhance overall turbine efficiency within a wider range of low wind velocity areas, compensating for the intermittency of wind in such locations.  These advantages are particularly important for urban environments, where the aforementioned challenges of wind power have left many a project stuck at inception.

The continued development of technology such as SmartWind‘s is essential to the proliferation of wind energy the world over.  As innovative and flexible wind technology becomes increasingly available, utilities, and even individuals, throughout the globe will be more willing to give this form of sustainable energy a real shot.

South African Government Confuses Renewable Energy Developers and Investors

The process of promoting generation of renewable energy in South Africa takes a long time. This is not a surprise, that was the case with many countries, as well as Israel. Recently, It was published that the regulator is considering to abandon the Feed-in-Tariff process which puts the tariffs in advance and is reviewing the possibility to go for a bidding process where the winner would be the bidder that will offer the lowest price.

I think that the South African misses two important points. It will leave the game for the biggest players only and will lose an opportunity to create jobs around the evolving renewable energy market, or at least, will create much less jobs. Second, the bidding process has proved itself an efficient and at least in Israel failed to meet time targets and is to be abandoned.

Israel dealt with a similar debate, whether to adopt the Feed-in-Tariff method or the bidding method to promote the generation of renewable energy into the grid. While the electricity Authority (the equivalent body in Israel for NERSA) supported the REFIT process and the Ministry of National Infrastructures (the equivalent to the Department of Energy) and the Ministry of Finance preferred the Bidding process. Israel decided to publish REFIT in 2008, while issuing few tenders in the bidding process.

While the bidding based projects are not making big progress the REFIT based projects generate 100 MW of small systems today, an approved accumulated capacity of 150 MW that will be implemented soon. Quota of 300 MW for medium size plants was published, projects with the accumulated capacity of 200MW where given licenses and other are awaiting approval – out of 1.3 GW of proposals.

Tenders in the bidding process published in 2008 and no one was awarded the contract yet. There is only one participant in each one of in two tenders for CSP plants (100MW each). There is also a tender for a PV plant (30MW) but bidders didn’t submit their final proposals yet.

  • Promotion of entrepreneurship and job creation: The Bidding process limits the game to few big players and excludes the small ones. The REFIT process allows to small and medium companies to participate. Israel developed an entire new renewable energy industry with close to a 100 active companies.
  • Efficiency: In bidding process the government becomes very involved and often intervenes in engineering and technological issues that is not capable to deal with. That’s creates delays and complications in the process.
  • Meeting the targets: Publishing tenders takes a lot of time, often much more than expected. That can result in not meeting the schedule targets. There is also a fear that companies that will lose the tenders will appeal to court and create more delays.
  • Simple rules of the game: the REFIT process puts together very simple rules that make it more transparent and easy to deal with.
  • The disadvantage of the REFIT process is that prices set at the beginning of the process do not reflect reduction in costs for the developers in the future. The solution is to publish quotas and a gradually decreasing REFIT.

All countries in Europe have decided to adopt the REFIT method. Israel found it as the most efficient way to promote renewable energy. I hope that South Africa will take the same way.

Dr. Ilan Suliman, former Vice chairman of the Israeli Electricity Authority has helped in putting these points together.

Never Too Late to Tell a Good Story:Israeli Energy Companies dominated Energy Conference in Johannesburg in March

My apology for the delay. It just has been a hectic period. too much work and too much public holidays – dangerous combination.

Just a week before a visit of 10 Israeli energy companies, the South African energy regulator, NERSA, decided to publish a consultation paper that aims at the slashing of the feed-in-tariffs by 20% to 40%. That was a blow to the efforts that we made and lots of companies did – not only from Israel. It seems to me that South Africa does the same mistakes Israel did, just few years ago (Israel is ahead than South Africa and has published the tenders for renewable energy generation).

The main two mistakes of the South African government are that they do not understand the importance of an aggressive promotion of the renewable energy projects in their first steps. Another problem is that different South African government entities do not speak in one voice. Israel did the same 2 mistakes at the beginning. But – as we gave it the necessary resources and government entities coordinated their efforts, the projects started running.

The Director General of the Ministry of Industry Trade and Labour of Israel, Mr. Sharon Kedmi, headed the delegation and spoke at the Cleantech day of Power & electricity World Africa said to his South African and African fellows: : you can make your own mistakes, but do not repeat ours – there is no point doing that!”.

The Israeli delegation included 10 companies in the areas of concentrated PV, PV panels, PV generators, solar water heating and more.

The National council for Economic Affairs of Israel, headed by Proph. Eugene Kandel has put together a programme to promote the search for substitutes of fossil fuel for transportation usage. The Programme includes the establishment of venture capital funds in collaboration with the private sector.

An annual budget of NIS 180 Million will be added to the Ministries of Industry and Trade, Ministry of National Infrastructures and Ministry of Science.

The Israeli company Better Place of Mr Shai Agasi is a world leader in the development of an electric car and more than that, the creation of a national infrastructure to support electric cars with charging points. The company works closely with the Israeli government to put together a policy that will promote the use of electric cars in the Israeli market. Israel is expected to be the first country to establish such an infrastructure on a large national scale.

Israel Newtech in South AfricaDue to its lack of oil reserves, Israel is completely dependent on expensive oil imports. In light of the country’s rapid economic and population growth, it has become challenging to supply its own peak electricity demands. These challenges are inspiring Israeli researchers and entrepreneurs to work on cutting-edge renewable energy technologies. It has led the government to introduce feed-in-tariffs, for large-scale solar power plants and for PV systems up to 50 kWp. That is in addition to the very successful use of solar water heaters by 95% of the households in the country. Full article.

Few days ago I visited the installation site of 117 solar water heaters on the roof of the Legacy hotel in Sandton. The Israeli-South African company Kayema installed equipment of the Israeli company Rand and has shown to everybody that it is possible! The Legacy hotel (still under construction) would be able to save about 16% of its energy costs. Full article.
