China To Lead Global Wind Energy Development

There is good news in the wind for environmentalists. Wind turbine capacity has been increasing and the unit cost of power generated by wind energy is expected to drop, much of which is credited to China’s efforts.

The World Wind Energy Association forecasts that by 2020, wind turbine total installed capacity will reach an estimated 1.5 million megawatts worldwide, accounting for 20% of global electricity consumption. This will represent a substantial jump in the role of wind energy in the next decade, where it represented just 1.5% of global electricity consumption in 2008.

Where news of environmental pollution is an issue of concern in China, it is also China that is set to take the lead in the global wind energy revolution, ahead of the United Kingdom or the United States, who have long been its strongest advocates.

It’s a paradox that in the West, proponents of the green movement protest against the very infrastructure that is needed to drive sustainable energy practices. There is a ‘not in my back yard’ mentality. This paradox is not seen in China. China will not only become a global leader in wind energy, but may be an important supplier to fast growing emerging Asian economies, such as Vietnam, Thailand and Indonesia, who themselves have limited development in the wind energy technology sector.

The Chinese government’s firm commitment

The Chinese government regards the development of wind energy as a key priority. At the end of 2008, China overtook India in having the highest installed capacity of wind energy in Asia with a total 12.2GW of total installed capacity versus India’s 9.6GW.

The Chinese wind power equipment manufacturing industry has been attracting the investment from many enterprises. With market capacity of wind power equipment forecasted to reach 32 billion US dollars by 2010, investing in China is important for many foreign enterprises wishing to take advantage of the substantial and rapid build up of wind energy in China.

In addition, overseas turbine companies have made substantial investments in China, in order to comply with an earlier government stipulation requiring at least 70 percent of components to be sourced domestically for use in Chinese wind energy projects.

In order to meet the demands of the growing market, domestic production and technology of wind turbines and components also had to step up. With this accelerated development of manufacturing, China is gearing up to meet both the domestic demands as well as preparing to supply components to the international market.

Key trends in China’s wind energy industry

1. Supply shortage for wind turbines and associated components predicted

The demand for wind turbines and related components in many countries is increasing. Together, the United States, the European Union and China are targeting to have installed capacity of about 400 to 500 gigawatts by 2020.

Only a number of specialised suppliers are able to produce key parts for higher capacity wind turbines however, and demand may overwhelm some suppliers, especially for those specialising in gearboxes and bearings. In addition, other industries also use similar wind turbine components for their equipment and machinery.

As an emerging technology, wind turbine designs are still evolving. Parts made are mostly customised and non-interchangeable, making replacement suppliers hard to find. Moreover, the advanced technology required to enter the wind turbine industry is a barrier for new entrants.

Currently, most Chinese wind turbines and components for higher-megawatt products are licensed or jointly developed with overseas players, whilst local manufacturers still lack the independent capacity to build higher wattage turbines. With fewer players supplying the higher-megawatt products, there are bottlenecks affecting the supply shortage for wind turbine related equipment, particularly with the government’s emphasis on higher wattage turbines.

Price volatility for raw materials, notably steel, copper and carbon, is a critical factor in some of the wind turbine parts. Steel is used in towers, gearboxes and rotors; copper used in generators and carbon in rotor blades. Any price volatility can result in bottlenecks in the supply chain.

2. More partnerships amongst wind turbine industry players

In order for foreign players to ease their market entry and secure consistent supplies and services, partnerships in the form of mutual agreements, joint ventures or acquisitions between market players; such as wind farm developers or operators, wind turbine manufacturers and wind turbine component manufacturers, will continue. Through such ventures, local players will in turn get to secure proprietary technology.

Examples include Shanghai Electric’s joint effort with German Aerodyn, and Zhejiang Windey’s partnership with Garrad Hassan and Partners Ltd (GH) from the United Kingdom.

3. Local technological advancement

Due to market regulation in China that favours locally made products, foreign players wanting to enter China need to work with local Chinese companies. This in turn, promotes technology transfer amongst Chinese companies and builds local expertise.

An example of this is Sinovel’s joint program with Austria Windtec. Sinovel is developing a three megawatt double feedback, variable shift and constant frequency wind turbine system, the first high-tech Chinese offshore wind turbine system, which will be installed in the first offshore wind farm, the Shanghai Donghai Bridge Wind Farm.

4. China as a major supply chain centre within wind energy industry

If current trends persist, China will become an important global supplier for the wind energy market, especially in key wind turbine components and services. High local demand, China’s strategic location to supply Asian markets with parts and equipments, coupled with development of local research and development skills may encourage a future role as a global wind energy hotspot for services and equipment.

China’s increasing ability to manufacture more affordable wind power equipment might even push South East Asia’s wind energy utilization, especially for small to medium scale projects. While the Chinese government is actively promoting the production of turbines with capacities of over two megawatts, Chinese suppliers are still catching up to the technology. For now, their strength will continue to be in small to medium scale wind energy projects, which are a good fit for South East Asia markets.

5. China wind energy suppliers go global

Chinese suppliers’ interest in European companies may be of strategic geographical importance in the long term.

Chinese market leader Goldwin has acquired majority share of German Vensys in order concentrate on the development of its direct drive wind turbine technology. After the acquisition of Vensys, Goldwind also bought the subsidiary companies that produced converters and variable propeller systems for Vensys, through Vensys in Germany.

For Goldwin, this ensures a local foothold in Europe with spin-off benefits both in Germany as well as in China. It has also absorbed a number of cross-border talent with management experience in the domestic and international markets from companies such as Shenzen

Huawei, Motorola, General Electric, the bearings industry SKF, Siemens and ABB.

China has been described as the world’s factory. In wind energy, the global environment would be the benefactor of its manufacturing prowess.

Fatal Forecast $11.99 A true story of catastrophe and survival at sea, Fatal Forecast is a spellbinding moment-by-moment account of seventy-two hours in the lives of eight young fishermen, some of whom would never set foot on dry land again. On the morning of November 21, 1980, two small Massachusetts lobster boats set out for Georges Bank, a bountiful but perilous fishing ground 130 miles off the coast of Cape Cod. The National Weather Service had forecast typical fall weather, and the young, rugged crewmen aboard the Sea Fever and the Fair Wind had made dozens of similar trips that season. They had no reason to expect that this trip would be any different. But the only weather buoy on Georges Bank was malfunctioning, and the National Weather Service had failed to share this fact with the fishermen who depended on its forecasts. As the two small boats headed out to sea, a colossal storm was brewing to the southeast, a furious maelstrom the National Weather Service did not accurately locate until the boats were already caught in the storm's grip, trapped in the treacherous waters of Georges Bank. Battered by sixty-foot waves and hurricane-force winds, the crews of the Fair Wind and the Sea Fever (captained by Peter Brown, whose father owned the Andrea Gail of Perfect Storm fame) struggled heroically to keep their vessels afloat. But the storm soon severely crippled one boat and overturned the other, trapping its crew inside. Meticulously researched and vividly told, Fatal Forecast is first and foremost a tale of miraculous survival. Most amazing is the story of Ernie Hazzard, who managed to crawl inside a tiny inflatable life raft and then spent more than fifty terrifying hours adrift on the stormy open sea. By turns tragic, thrilling, and inspiring, Ernie's story deserves a place among the greatest survival tales ever told. Equally riveting are the stories of the brave men and women from the Coast Guard and the crew of a nearby fishing boat who imperiled their own lives that day in order to save the lives of others. As gripping and harrowing as The Perfect Storm - but with a miracle ending - Fatal Forecast is an unforgettable true story about the collision of two spectacular forces: the brutality of nature and the human will to survive.

Wind Energy Equipment in India $195 How to Strategically Evaluate India. Perhaps the most efficient way of evaluating India is to consider key dimensions which themselves are composites of multiple factors. Composite portfolio approaches have long been used by strategic planners. The biggest challenge in this approach is to choose the appropriate factors that are the most relevant to international planning. The two measures of greatest relevance to wind energy equipment are “latent demand” and “market accessibility”. The figure below summarizes the key dimensions and recommendations of such an approach. Using these two composites, one can prioritize all countries of the world. Countries of high latent demand and high relative accessibility (e.g. easier entry for one firm compared to other firms) are given highest priority. The figure below shows two different scenarios. Accessibility is defined as a firm’s ease of entering or supplying from or to a market (the “supply side”), and latent demand is an indicator of the potential in serving from or to the market (the “demand side”). Framework for Prioritizing Countries. Demand/Market Potential Driven Firm. Relative Accessibility. Accessibility/Supply Averse Firm. In the top figure, the firm is driven by market potential, whereas the bottom figure represents a firm that is driven by costs or by an aversion to difficult markets. This report treats the reader as coming from a “generic firm” approaching the global market – neither a market-driven nor a cost-driven company. Planners must therefore augment this report with their own company-specific factors that might change the priorities (e.g. a Canadian firm may have higher accessibility in Canada than a German firm). Latent Demand and Accessibility in India. This report provides a detailed overview of factors driving latent demand and accessibility for wind energy equipment in India. Latent demand is largely driven by economic fundamentals specific to wind energy equipment. This topic is discussed in Chapter 2 using work carried out in India on behalf of American firms and authored by the United States government (typically commercial attachés or similar persons in local offices of the U.S. Department of State). I have included a number of edits to clarify the information provided. Latent demand only represents half of the picture. Chapter 2 also deals with micro-accessibility for wind energy equipment in India. I use the term “micro” since the discussion is focused specifically on wind energy equipment. Chapter 3 is also a stand-alone report that I have authored. It covers proxy pro-forma financial indicators of firms operating in India. I use the word “proxy” because the provided figures only cover a “what if” scenario, based on actual operating results for firms in India. The numbers are only indicative of an average firm whose primary activity is in India. It covers a vertical analysi

South Africa: Wind Energy Barriers $51.99 Hauptbeschreibung The rapid adoption of wind energy in the renewable energy mix can be seen in many industrialized nations in the past decade, in particular the need to agreed greenhouse gas reduction and stable energy supply are seen as a sound vision for a sustainable energy policy'. In an emerging market such as South Africa there are abundant renewable resources including wind energy, however there is low adoption observed to date. This study investigates barriers to entry in the South African wind energy sector and what the priorities are to remove such barriers for successful deployment of wind technology. Therefore, it was required to examine successful deployment of wind energy in the European Union and how such barriers were removed; this was set in the current status of the renewable energy sector and existing barriers in South Africa. It was necessary to gain insight of the inter-related issues on opening a traditional fossil fuel based energy market to a transitional implementation of renewable energy provisioning, considering the current utility monopoly based energy landscape in South Africa.   Biographische Informationen The author works in the area of Global consulting in Environment, Infrastructure Utilising Renewable Energies multiple sectors.
