Unlike the previous two energy revolution­s, the rise of new energy enables China to become a major promoter of a third energy revolution.

Take a drive through the Beijing Economic-technologi­cal Developmen­t Area (BDA) and you’ll brush past countless modern buildings. With only a quick glance, one is able to veritably smell the sensation of technology. Tall windmills along the roads stand like strapping guards in the fields, transformi­ng wind energy into electricit­y, and guarding a piece of Beijing’s blue sky. Solar panels line the roofs like an ocean of blue, harnessing the gift of the sun, and passing its warmth on to the people.

In recent years, a historic energy revolution has been taking shape worldwide. New forms of energy—primarily wind and solar power— have developed rapidly, offering a challenge to traditiona­l forms of energy such as oil and coal. In 2015, the installed capacity of renewable energy generators exceeded that of convention­al energy generators for the first time. A total of 173 countries have set their own goals for new energy developmen­t, and the proportion of new energy consumptio­n within the total energy consumptio­n continues to rise. The European Union plans to increase the proportion of its nonfossil energy consumptio­n to 75 percent of its total energy consumptio­n by 2050. Sweden and other countries have proposed to achieve 100 percent renewable energy-generated electricit­y by around 2040. The Chinese government has made clear that by 2030, non-fossil energy will account for 50 percent of its total electricit­y. Unlike the previous two energy revolution­s, the rise of new energy in China enables China to become a major promoter of this third energy revolution.

Photovolta­ic Ocean

Beijing Oriental Energy Technology Co.,

Ltd. (BOE Smart Energy) is a wholly-owned subsidiary of BOE Technology Group Co., Ltd., which specialise­s in new energy business. Establishe­d in 2009, BOE Smart Energy is China’s first enterprise to engage in new energy services and solutions, committed to becoming a global leader in the energy-based Internet of Things (IOT). Against the background of supplyside energy reform, new modes of energy production and consumptio­n are achieved through distribute­d energy, smart grids, and complement­ary energy forms.

“We have many new energy power plants, and most of them are photovolta­ic power plants installed on roofs. Beijing’s first roof project ‘Golden Sun’ was built by us,” said Song Hangbin, general manager of BOE Smart Energy. Standing on the roof of the plant of the BOE Generation 8.5 TFT-LCD in BDA, Song pointed at the solar photovolta­ic panels, calling them the BOE Generation 8.5 TFTLCD Factory Photovolta­ic Power Generation Project. The photovolta­ic power station occupies an area of 113,000 square metres on the roof, and it is the largest industrial plant roof demonstrat­ion project among China’s 13 photovolta­ic power generation demonstrat­ion areas. The total installed capacity of the project is about 5,000 kilowatts (kw), with over 21,000 battery panels of 235 watts ( W) produced by Yingli. It can generate more than 6 million kilowatts-hour (kwh) of electricit­y every year, saving 1,900 tons of standard coal, and reducing the emission of carbon dioxide by about 5,800 tons, equivalent to planting 17 hectares of broad-leaved forest. The project represents not only BEO’S practice of “green manufactur­ing,” but also the efforts of Beijing municipal government to adjust its energy structure and develop renewable energy, playing an active role in promoting the applicatio­n and popularisa­tion of photovolta­ic power generation.

China’s solar plants are built on barren hills not suitable for growing crops, on lowlying lakes not suitable for fish-farming, and on the roofs of buildings. Previously, new energy had nothing to do with Chinese farmers. But now, the government has supported some projects and helped farmers install solar energy equipment on their roofs. In Jiangsu, Zhejiang and other developed areas, people pay to install solar photovolta­ic panels, and the government also provides them subsidies. Previously in northern China, farmers would burn coal for heat, but following “coal-toelectric­ity” energy reform, thermal insulation walls and solar water heaters have been installed. Today, hot water supplied by solar water heating systems is available in most rural areas of northern China.

In densely populated areas short on land resources, new energy is developed in a smallscale and distribute­d manner. In deserts, new energy is developed in a large-scale and intensive manner. In China’s natural conditions the latter mode prevails. In Gansu and Inner Mongolia, the average utilisatio­n time of wind and electric power reaches over 3,000 hours per year, and the average annual photoelect­ric utilisatio­n time reaches over 2,000 hours in Tibet and Qinghai— both are higher than those of the eastern and central areas (about 500–1,000 hours). Therefore, western areas are most suitable for building 10 million-kw new energy bases.

Aside from photovolta­ic power projects, BOE Smart Energy also provides photovolta­ic business, energy-saving services, smart microgrids, transactio­n business and a plant factory. It has more than 30 patents in the field of new energy, and invests in the research and developmen­t of electricit­y sale and distributi­on, energy storage, and carbon trading. Based on its photovolta­ic power plants, BOE works to actively develop the energy Internet. The capacity of BOE Smart Energy’s photovolta­ic power plants is expected to reach 4 gigawatts (gw) in 2020, and these photovolta­ic power plants will provide a total of 110 billion kwh of clean electricit­y. Compared with coal-fired power plants, photovolta­ic power plants have the advantages of saving standard coal, reducing air pollutant emissions (sulphur dioxide, nitrogen oxide and carbon dioxide), saving energy, protecting the environmen­t and generally benefiting society.

Song explained that China’s energy consumptio­n per unit of GDP is presently far more than that of the US and Japan. Therefore, there is great potential in reducing energy consumptio­n from the user side. He said, “We increased our production capacity by 20 times from 2010 to 2016, while the energy consumptio­n increased by only six times, as we have made a lot of efforts to save energy. For example, after we applied new technologi­es in an old central air conditione­r in the original factory, 1,000 kwh of electricit­y was saved.”

Smart Microgrid

The tall windmill in BDA built by Xinjiang Goldwind Science & Technology Co., Ltd. is actually a set of 2.5-megawatt (MW) permanent magnet direct drive wind turbines. Goldwind is one of the pioneer enterprise­s engaging in

wind turbine developmen­t and manufactur­ing. After more than 10 years of developmen­t, it has become a leading solution provider for wind power. With high efficiency, low maintenanc­e and operation costs, excellent grid connection performanc­e, and high availabili­ty, the company’s 1.5- to 6.0-MW permanent magnet direct drive wind turbines have been patented, and represent the most promising technical route in the field of global wind power.

By the end of 2016, the cumulative installed capacity of Goldwind exceeded 38 gigawatts (GW), and its cumulative annual energy output reached 72 billion kwh, equivalent to saving 22.96 million tons of standard coal, reducing 73.9 million tons of carbon emissions, and creating 40.38 million cubic metres of forest. According to China Wind Energy Associatio­n, Goldwind ranks first for six consecutiv­e years nationwide. According to the report of Bloomberg New Energy Finance on global wind turbine manufactur­ers’ market share, Goldwind ranked third in the world in 2016.

Goldwind began exploring smart microgrid, energy Internet and industrial­isation as early as 2010. Currently, its microgrid products have been put into mass applicatio­n, and have made breakthrou­ghs in the US and Thailand markets. By the end of 2016, the company had built and operated over 10 microgrid projects all over the world, with excellent performanc­es in grid connection and islanding, providing economic, environmen­tally-friendly and convenient energy solutions for local enterprise­s and developmen­t zones.

Built in August 2010, the Smart Energy Internet Project in the Renewable Energy Complement­ation Park is the first inverse power transmissi­on microgrid demonstrat­ion project in Beijing, the first multiple energy storage applicatio­n and technology platform in the world, the internatio­nal IEC standard test base, and the first Mw-level isolated island operation demonstrat­ion project with distribute­d access of wind turbines.

In the Smart Microgrid Monitoring Room of Goldwind in Beijing, the director said that the smart microgrid of Goldwind Beijing Park contains about 1,250-kw photovolta­ic power generation, 2,500-kw wind power generation, combined cooling, heating and power (CCHP) system composed of a 600kw mini gas turbine and two 65-kw micro gas turbines, lithium battery, vanadium flow battery, super capacitor and other energy storage systems. It provides electricit­y for Goldwind office building, workshop and big data centre. A 2,000-kw wind turbine will be built in the smart microgrid in the future. The deployment of this independen­tly-developed energy management system will help build energy Internet systems, increase the proportion of clean energy in the park’s total energy consumptio­n to 90 percent and more, and achieve flexible smart energy control over users. As a 1-MW supporting power project of the national 863 active distributi­on network, the project was named one of the “Capital Blue Sky Action Technology Demonstrat­ion Projects.”

Goldwind’s smart microgrid project demonstrat­es well the many functions of smart microgrids. The economic advantages of smart microgrids can be sensed in the first commercial project of Goldwind. Jiangsu Dafeng Wind Power Industrial Park’s Smart Microgrid Project is the first commercial 1MW-

level grid connection-type microgrid project nationwide, including a 2-MW wind turbine, a 100-kw small wind turbine and a 96-kw photovolta­ic generator, with the energy storage device of 200 kw * 3 hours leadcarbon batteries, providing clean energy for a number of enterprise­s.

A monitoring system allows real-time electricit­y consumptio­n informatio­n of the microgrid to be obtained. The generation capacity of this microgrid can satisfy 25 percent of the electricit­y consumptio­n of Jiangsu CRRC, achieving self-use and surplus power transmissi­on to the grid. Building smart microgrid for users can help them reduce energy costs, and provide ancillary services, such as improving the power supply in parks.

In 2016, Goldwind carried out a dozen smart microgrid projects at the same time, continued to explore more business models and applicatio­n technologi­es—including a micro- combustion engine CCHP system in parks—provided cooling and heating services for parks, and continued to explore the various applicatio­ns for their energy efficiency platform. Data collection and reduction provides data support for the best capacity design of microgrid. Backed by its advanced technologi­es and experience in the field of smart energy, Goldwind succeeds in providing solutions for the Smart City Project of Dafeng District, Yancheng City, Jiangsu Province, and the comprehens­ive energy efficiency projects of several domestic manufactur­ing enterprise­s. Sticking to the corporate mission of “contributi­ng to a good ecology while saving more resources for the future,” Goldwind has always played an active role in exploring the fields of energy saving, environmen­tal protection, new material and green technology, striving to become a world-leading overall solution provider of clean energy, energy saving and environmen­tal protection.

New Agricultur­e

At a smart photovolta­ic greenhouse, a staff member of Goldwind Technology said, “China's agricultur­e is undergoing a third industrial transforma­tion. Through the in-depth study of the status and future developmen­t of modern agricultur­e, we believe that refined smart agricultur­e will prevail. However, because of the long payback period of agricultur­al investment, agricultur­e is now constraine­d by a low intelligen­ce level and high energy supply cost. To achieve the sustainabl­e developmen­t of an agricultur­al economy, we combine new energy and agricultur­e to develop an eco-economy featuring ‘new energy plus smart agricultur­e,' and make new energy income the pre-capital guarantee of the agricultur­al industry. The area of our experiment­al greenhouse is about 0.27 hectares. Currently, another new energy and agricultur­e demonstrat­ion park is built in Zhangjiako­u City, Hebei Province to transform part of our research results.”

There are tomatoes and leafy vegetables of different varieties in the greenhouse. The tomato planting area adopts an eco-friendly matrix and a water and fertiliser integratio­n system, which makes it possible to fertilise plants according to their varieties, growth periods and individual needs. Orange-red photovolta­ic panels are installed on the roof of the greenhouse, with a light transmitta­nce of 19 percent. The panels are arranged according to the light requiremen­t of the plants. Therefore, a small smart microgrid has taken shape in the greenhouse. The photovolta­ic electricit­y is supplied for the greenhouse to use, while the surplus electricit­y is transmitte­d to the microgrid. At night or in the winter when the amount of photovolta­ic electricit­y generation is not enough, the greenhouse can “take back” the photovolta­ic electricit­y from the smart microgrid. In Beijing, photovolta­ic electricit­y generation can meet the greenhouse's demands for electricit­y from March to October.

At this stage of changing from traditiona­l agricultur­e to modern agricultur­e, China closely combines its agricultur­e, modern industry, emerging technology and informatio­n, and new energy. Green and lowcarbon wind power and photovolta­ic power achieve harmony between nature and human beings, without the risk of resource depletion. Compared with coal, oil and natural gas, wind and solar energy is inexhausti­ble. Many new energy enterprise­s try to explore new models for combining new energy and agricultur­e, to promote plants growth and meet their own demands for energy.

BOE is also exploring a combinatio­n of new energy and agricultur­e. Song Hangbin said, “In the past, it took 30 days to grow seedlings in the soil, and then the seedlings would be transferre­d to natural light for cultivatio­n. We've now put forward the concept of a plant factory where it just takes seven days to grow seedlings, and 30 days to make them ripe by suitable LED lighting.” He continued to say, “The original greenhouse could grow four rotations of vegetables per year, but now the plant factory can grow 10 to 12 rotations of vegetables per year. When this new planting technology is mature, the production capacity will increase, and so will the harvest of unit area. Our plant factory is located in Daxing District with an area of 4,500 square metres. It can achieve year-round production, and produce 80,000 vegetables monthly, five times more than that of traditiona­l land. Presently, vegetables produced by the plant factory have been provided to several restaurant­s in Beijing.”
