- Enel Green Power’s installed capacity in Brazil will double thanks to these new projects.

The company was awarded the contract based on three projects with very high wind potential and a capacity factor of around 50%, among the highest in the world. This means that the wind turbines will be able to generate power for over 4,000 hours equivalent per year, approximately twice the European average.

The contract was awarded via an auction through which only 528 MW out of around 7,000 MW authorized were awarded.

With an installed capacity of 30 MW each, Cristal, Primavera and Sao Judas – the names of these three EGP projects – will be able to generate over 390,000 MWh per year, equal to the consumption of around 245,000 Brazilian households and avoiding the emission of about 270,000 metric tons of CO2 into the atmosphere.
The wind generator farms will be constructed in the Brazilian state of Bahia and, due to their location in semi-arid areas, will enjoy incentives targeted at infrastructure development.

Through the tender, EGP also gained the right to sign a 20-year contract to sell the electricity generated by the three plants through Brazil’s Chamber of Electrical Energy Commercialization at a price indexed 100% to Brazilian inflation.

“This result is very important to us, given the excellent qualities of our projects in terms of productivity, cost competitiveness and return on investment,” said Francesco Starace, President of Enel Green Power, “We are further reinforcing our presence in Brazil – where we are already active in hydropower, expanding our activities also in wind power generation. Brazil is a large market with wind power generators abundant renewable resources, and a demand for energy that reflects a continually developing economy.”

The three wind farms are scheduled to begin operation in the second half of 2013. These new plants will allow Enel Green Power to double its installed capacity in Brazil and significantly increase its wind presence in Latin America.

UK wind power developers have worried.

British National Grid announced in June a conference paper elaborated on the plan will include six nuclear power issue, but need to increase the total amount of national grid electricity reserves. Mentioned in the document which will effectively address the problem of insufficient supply a large number of power plants, from 1320 MW to 1800 MW. National Grid also said its operating costs from the estimated 16 million pounds a year to grow to 31.9 million pounds. The meeting made a number of energy companies charge to complement the national power grid method of rising costs, but the national grid transmission Bumen business director Alison wrote to the UK gas and electricity market regulator Ofgem’s letter has said that the Power Grid Corporation decided to retain the existing fee system that is national grid electricity supply companies to provide the same per MW of electricity will be charged the fees.

The decision to wind power generators operators almost fly into a rage, claiming the national grid charges which is extremely unfair. Although the National Grid, said at the meeting, continue with the current charging method is smaller than 350 MW for power generation companies, including wind power Baokuo English are not all caused additional loss but Reng not stop the protests Sheng Feng Dian enterprises. In contrast, nuclear power developers are on the national grid rather welcomed the decision, because they do not want a large-scale power plants to increase the national grid charges, this will be detrimental to the construction of new small wind generators nuclear power stations. Now this is because the cost of increased costs to be shared equally by the need to head all the energy companies, they naturally could not be happier.

The information from the meeting revealed that many users have increased costs may lead to a large nuclear power plant commissioning was delayed for several years. The lack of electricity power supply enterprises, it is possible through a new gas turbine combined cycle (CCGT) power plants to compensate. And to do so will complete the UK and across Europe to bring their emissions reduction targets hampered because of the low-carbon technology investment will inevitably be affected. Not long ago, a National Grid spokesman said in an interview acknowledged that their decision may make wind power operators feel disappointed. But he wind turbine generator also stressed that the development of large wind power companies to move offshore wind power plant is gratifying, because the power to enhance the scale means that they do not now face additional charges. But in fact, even in the offshore wind farm operators, the decision to support the national grid are also very few people. Moreover, many wind power companies have expressed the hope that Ofgem will make the decision to wind turbine change the national grid, because they believe doing so is tantamount to the national grid to wind power and other renewable energy back to nuclear power a heavy burden.

Currently, Britain has 253 wind farms, including 12 seats in the sea, therefore, the future growth of renewable power, offshore wind power will play a vital role. According to data from PricewaterhouseCoopers, when the British offshore wind power capacity to reach 12 gigawatts, in fact the UK last year, the total installed capacity of 0.3 GW, which means that the country’s offshore wind power requires about 300 million pounds investment. This figure for the current British offshore wind power dwarfs the actual level of investmentsmall wind generator-wind turbines-wind generators-small wind turbine .
It is understood that the UK is now on public utilities and the national grid each year’s investment total only about 8 billion pounds. In view of the construction of offshore wind farms average more than 3 years, each year nearly 3 billion pounds invested, so that by 2015, the cumulative funding shortfall could reach 10 billion pounds. “Britain’s offshore wind power areas that require huge capital,” the energy department heads  PricewaterhouseCoopers in an interview said, “very slow progress of the relevant companies. The United Kingdom if they wish to realize the goal of renewable energy must substantially increase the rate of development of wind power. ”
It is said to make up for gaps in funding the development of offshore wind power development in the UK is facing major problems. British Government’s current economic situation is difficult stretched out a lot of money into offshore wind power, banks are also affected by the economic crisis drag helpless. Hurley pointed out that PricewaterhouseCoopers, the UK can currently use renewable energy incentives mechanism also Yuan Bugoubaozheng Dianliqiye the necessary funds if the wish to further Ciji on offshore wind Touzi, the most simplest way is to follow the United States, Zai increase the consumer’s bill, although the exact figure is still very difficult to estimate. Another approach is the basis for offshore wind farm construction onto the existing power grid operators, but apparently not welcomed by the power company. In addition, the government has managed to increase offshore wind power granted tradable renewable energy obligation certificates (ROCs), as well as tax exemptions on investment-related technology and other methods to increase return on investment in offshore wind power. Of course, regardless of which method to take the huge financial support are essential.
Despite the financial difficulties they may face, there was still very optimistic about Britain’s offshore wind power industry. “In fact, huge amounts of money and a lot of infrastructure is not necessarily a need for new financing.” Trade organization “Renewable British” CEO  Friedrich said, “a large number of international investment The influx of those who will not only bring money, but also show that the UK is the development of offshore wind power profitable. “

Hawaii officials hope that by 2030, 70% of energy needs to provide the origin, while the state is facing the problem of wind power generation, mainly the power sector is not able to excess wind power output to close to the company, can not enter in the weak wind power. If the local Maui (Maui), total wind power capacity could reach the island, a quarter of the peak power, peak power and peak demand, but time is not the same, which brought to Hawaii to complete difficult goals.

“New York Times” said that the best option currently seems to use batteries. In New York and California, the power sector is to develop a power storage technology, even to “carry” the space, namely the use of such lower price to buy midnight hours of electricity sold at higher prices after a few hours . In the Midwest, public utilities shows another power storage technology, in a minute or less time may be repeated several times for the conversion charge and discharge, to help power against solar, wind and wave transmission failure. In Texas, power companies placed in different locations through a transmission line connection from the battery to stabilize voltage.

Many enterprises believe that the wind power industry, renewable energy goals can be achieved. Hawaiian Electric spokesman  (Peter Rosegg) said that if the energy source is intermittent, “No battery will not achieve its objectives.” The company has agreed to from the island of Oahu (Oahu) north of the coast to buy a wind farm power. 30 MW installed capacity of power plants by the Xtreme Power Company to install a 15 MW battery.

Luo Saige said the power plants in Hawaii the best location of wind farms is one of its power supply volatility and lack stability. In addition, the wind power generator market is Honolulu on the island farthest from the company’s load center location, even from the company’s high-voltage transmission backbone.

Xtreme Power president Kaluosike (Carlos J. Coe) said, the computer will try to keep the battery in the day most of the time in the semi-charged state. If the wind suddenly increased or decreased, the battery current will be stable, so that power seems to gradually increase or decrease.

Hawaii’s success lies in its wind power generation facilities, the frequency adjustment function. AC system to run 60 cycles per second, while the battery can be carried out in 60 seconds from the charge to discharge or change in the opposite direction, so as to maintain frequency stability. Battery system can be used for profit, at the lower price store electricity, while the release of higher electricity prices. The battery can hold 10 MWh of electricity, equivalent to a 30-megawatt power plant produces 20-minute full-load power delivery, amazing storage capacity.

First Wind Company and Xtreme wind turbines Power battery companies did not disclose the cost of the system, but public figures, the cost of the wind farm is about 130 million U.S. dollars, the battery system, which costs 10 million U.S. dollars, the U.S. Department of Energy provided 117 million U.S. dollars of loan guarantees. (1 U.S. dollar equals 6.78 yuan)

Power storage cost and value for consumers is difficult to predict. Off-peak electricity during the storage cost, and the highest cost of electricity is very expensive. “New York Times” said that if renewable energy sources to reduce dependence on coal and natural gas demand, which is an additional benefit.

Kaluosike estimate the efficiency of the battery system for more than 90%. If this figure is confirmed, the battery system is indeed a major step forward. Currently, the most efficient use of energy stored in the form of pumped storage power station comes as its efficiency of 70% to 85%.

Electricity sector also used to store electricity and other strategies for FM. Beacon Power is building a component from the 200 flywheel power storage libraries, storage grid electricity, and ensure accurate AC system in 60 cycles. The top of the flywheel is a generator or motor may be alternately used as a device that can store or access in the flywheel energy. U.S. Department of Energy cost of 69 million U.S. dollars for this project provided 43 million U.S. dollars of loan guarantees.

U.S. Department of Energy as the use of compressed air energy storage project to provide support. Surplus electricity to pump air into underground caves, when you need electricity, empty of air into the gas turbine generator

However, slow innovation and development of domestic enterprises will make a large number of wind power company, overheating in the next 35 years was eliminated.
Around half of last year wind generators overproduction provoked intense controversy after all, since the beginning of this year, wind power equipment overheating, both inside and outside the industry a further focus. How hot wind power equipment in the end, the development of wind power equipment industry will go? With these questions, before reporters interviewed some experts and wind power turbines equipment manufacturing business owner.
Hot hot wind power equipment
July 6, China Agricultural Machinery Industry Association, wind power equipment branch of the Deputy Secretary-General, researcher Chen Dechang in an interview, said that in recent years, launched the domestic wind power equipment small wind turbines manufacturers is a bit too much too fast, the two figures to illustrate this point: the world total of about 140 or so wind power equipment manufacturers, including China, accounted for 90, and 90 domestic wind power equipment that most companies is the recent 34 years there and developed.
Qingdao Wind Power Technology Co., Ltd. Shenzhen Min Jiang Chunhui, general manager, told reporters: “At present domestic enterprises engaged in production of wind energy equipment, at least above 100.”
Shende Chang said that in order to support local industry, relevant government departments to request “wind power equipment localization rate to 70% or more, does not meet the requirements of equipment localization rate does not allow construction of wind farms.” It is encouraged by national policy, launched around the rush of wind power projects, China has become the upper hand electrical equipment manufacturers in the world’s fastest-growing state.
Chen Dechang further explained that this year will reach the domestic fan installed 30 million kilowatts, which is the state planning to the development of wind power by 2020 target, the development of wind power equipment is really too fast
Lack of innovation and lack of core technology
It is understood that by the end of 2004 opened the domestic wind power industry market, the beginning of States to guide the development of wind turbines industry, the “introduction – absorption – another new” line of hope in the joint design with foreign firms based on the realization of independent innovation .
Aspirations of the country is full of good intentions, but four years later, the majority of independent innovation of enterprises has been slow.
Jiang Chunhui said, the reality is the technology re-introduction, lack of innovation, lack of core technology. “Many companies, after obtaining the support of the local government invested little in the fund to build plants, then the introduction of the equipment assembly drawings in accordance with the foreign owners to sell wind, reap the profit center.”
Chen Dechang also used to prove the reality of another domestic wind power equipment manufacturer technical deficiencies. He said: “At present, 90 domestic enterprises, only 20 have the production conditions, the other still in the prototype development stage.”
Qin Haiyan of China Wind Energy Association to the Secretary-General’s analysis, wind power technology for domestic and foreign, are faced with many technical issues need to study, the first to master the technology grasps the initiative.
90% of businesses will disappear
3 end of the month, the Department of Industry and Information Technology, the National Development and Reform Commission, National Energy Board and the drafting of the three ministries, organizations of the “access for wind power equipment manufacturing industry standard (draft)”, the establishment of enterprises from the production, process equipment, and R & D testing, product quality and after-sales service, technical progress, energy saving and comprehensive utilization of resources and other aspects on wind power equipment manufacturers put forward specific demands.
Shende Chang said: “The access standards, in principle, means that no approval of the new enterprises to enter the wind power equipment.”
Well, the Chinese wind power equipment market, and can only put the number of family traditions of electrical equipment companies stay in business?
Qin Haiyan am rather optimistic. He told reporters: “By 2020, our non-fossil energy in the share of primary energy increased to 15%. To achieve it, we believe that wind power installed capacity to reach from 120 million to 150 million kilowatts. If 2020 is 120 million kilowatts, the next 10 years, the additional installed capacity per year at least 10 million kilowatts, so our domestic market potential is enormous. ”
However, Chen Dechang Quedui capacity of the domestic market to a decisive answer: the domestic market can only put up no more than 20 family traditions electrical equipment manufacturers.
Chen Dechang calculations to reporters, currently ranked the top 10 domestic wind energy equipment business, production accounted for 80% of the domestic market, pre-15 accounts for 95% of the market, and the remaining 5% of the dozens of good points, they can earn much money? An installed capacity of wind power equipment business volume of 500 thousand kilowatts in order to guarantee no loss, while the installed capacity of our country for one year a total of only 10 million kilowatts.
Shende Chang said: “The light does not make money making things definitely quit crying, the wind power industry in the next 35 years, certainly 90% of the wind turbine generator equipment company through restructuring, mergers and other channels disappear, even though each of these companies now is full of confidence. Only those products are technically advanced, stability, economy, equipment, better performance than similar products, technically innovative technology companies to stay perfect.

State “long-term renewable energy development plan” put forward in 2010 and 2020, total installed capacity of wind power to the country to reach 5 million kilowatts, respectively, and 30 million kilowatts; equity total installed generating capacity of more than 5 million kilowatts of investors, the of non-hydropower renewable energy interests to be separately installed capacity to meet its total installed capacity of power generation interests of 3% and 8%.
Feng-play said: “The goal in this request, the generation companies and local governments will be installed capacity as a performance appraisal standards, wind speed Dianyuan construction increased significantly. Even there the project is not approved, start the construction of wind farms on the phenomenon of Some units are not followed by hoisting the Internet, unable to pronounce the power. ”
According to the China Hydropower Engineering Consulting Group Expert Committee Shi Pengfei introduced in 2009, new wind power installed capacity in China ranks first in the world, lifting capacity of 12.02 million kilowatts, but after debugging and a wind turbine power generation capacity of 8.28 million kilowatts More than 30% of installed capacity appear idle.
As of the end of 2009, China’s first 10 million kilowatts in wind power base in Jiuquan, Gansu Province, wind power installed capacity has reached 2.2 million kilowatts, but the actual grid power generation capacity of only 897,100 kilowatts fans.
Feng-play, said the revised “Renewable Energy Law,” proposed a full protective grid enterprises purchase renewable energy electricity generation Internet, also provides for the cost of power grid enterprises can do to increase renewable energy development fund to get assistance. Feng-effect that in order to correspond with the regulations, it is necessary to Wind Power Generation Enterprises in the proportion of consumption accounted for as a rigid goal should be finalized.
