Silicon wafer accounts for 30%-40% of the cost of a solar module. Larger wafer size increase the area exposed to light, increasing power and reducing cost. So that, since 2H-2018, the industry has continued to develop larger size wafers, leading to various specifications.

LONGi Solar has launched recently a press release stressesing the need for consistency in standards for PV wafers size. As the press release states, according to Professor Shen Wenzhong, Director, Solar Energy Research Institute of Shanghai Jiaotong University: “The 166 mm wafer has reached the allowable limit of production equipment which is difficult to overcome. This would be the upper limit of the standard for a considerable period.”

Li Zhenguo, President of LONGi Group considers that these different wafer sizes will lead to a mismatch in processes and standards in the supply chain, according to. “If manufacturers cannot reach an agreement on a size standard, it will restrict the development of the whole industry.” said.

Shen Wenzhong also said: “Existing crystal drawing and slicing equipment are compatible with 166 mm size silicon wafer. Production equipment for cell and module needs to be modified, though the costs are lower and easier to achieve. Calculated by “flux”, cell and module production line using 166 mm wafer will increase capacity by 13% as compared with the 156 mm size”.

The order books for LONGi’s Hi-MO4 modules using M6 monocrystalline silicon wafers, 166 mm, have exceeded 2 GW, so that large-scale production will commence the third quarter of 2019.

By the end of 2020, LONGi will upgrade its existing cell and module lines and transform them for production with 166 mm wafer. New lines – such as the 5 GW monocrystalline cell line in Yinchuan – will be designed for the 166 mm size from the start.

LONGi announced the price of its M6 monocrystalline silicon wafer in May-2019 at 3.47 RMB/piece, which is only a small 0.4 RMB premium compared to its M2 wafer. According to LONGi, the compatibility of wafer production lines with M6 would ensure large-scale supply in 2019, thereby reducing the price differential to less than 0.2 RMB.

The energy storage market has caught the eye of a number of stakeholders involved in the power industry, leading to its considerable growth and opening the way for next energy revolution, says GlobalData. GlobalData’s latest thematic report, ‘Thematic Research: Energy Storage’, highlights the present scenario and emerging market trends in the global energy storage industry, and the key companies behind the development of three energy storage technologies: electrochemical, mechanical and thermal energy storage.

The energy storage market is nascent but fast-growing. The demand for energy storage system (ESS) devices in the power sector is increasing rapidly, particularly after the increase in the renewable energy integration into the grids. Intermittent power supply led to demand for the storage of electrical energy and supply during peak load periods. ESS devices can help make renewable energy -whose power output cannot be controlled by grid operators- smooth and dispatchable.

With the global energy storage market becoming one of the rapidly growing segments within the renewable power mix, equipment manufacturers or technology providers of energy storage technologies are focused on innovating their energy storage solutions and offering advanced energy storage systems.

Battery energy storage system (BESS) is regarded as a crucial solution for overcoming the intermittency limitations of renewable energy sources (RES). The battery energy storage market reported cumulative deployment of 4.9 GW at the end of 2018 and is expected to reach 22.2 GW in 2023, with the US accounting for 24.7% of the global capacity. The deployment is expected to grow, due to a large number of countries opting for storage utilization to support their power sector transformation.

The expansion in battery manufacturing capacity and falling costs resulting from the electric vehicle (EV) industry are driving growth in energy storage services and new markets. This fall in battery prices has favored the battery energy storage market and has speeded the deployment of energy storage projects globally.

Currently, lithium-ion (Li-ion) batteries dominate the electrochemical energy storage market but other battery energy storage technologies such as sodium-sulfur (NaS), lead-acid and flow batteries are now getting deployed. While, thermal energy storage utilizing molten salt is among the most widely used technology in association with concentrated solar power (CSP) projects, among mechanical energy storage technologies, pumped hydroelectric storage systems is among the most mature energy storage technologies and offers a number of benefits such as energy-balancing, stability, storage capacity, along with ancillary grid services which include network frequency control and reserves.

The four conferences of The smarter E Europe, the innovation hub for empowering new energy solutions, offer an insight into the energy future as well as information about current technological trends and business models. They include the Smart Renewable Systems Conference, Intersolar Europe Conference, ees Europe Conference and Power2Drive Europe Conference. On May 14 and 15, attendees can gain access to all four events in Munich with just a single ticket. The conferences cover aspects of tomorrow’s decentralized, digital and renewable energy supply and bring together the most important stakeholders in the energy industry.

Renewable energies already play a major role in the supply system today. From generation and storage to distribution and usage, in the future every step in the entire energy supply chain needs to seamlessly merge together to operate and interact intelligently. And the renewable energy market keeps on growing. This is due to falling costs and new scopes of application as well as new business models and stakeholders entering the market. The energy industry is changing, becoming increasingly decentralized, digitalized and environmentally friendly.

The road to this new energy world and the rules of the game are explained by leading experts from the clean energy industry at four conferences.

Intelligent energy systems in the spotlight

At the Smart Renewable Systems Conference, the spotlight is turned on intelligent energy systems, from virtual power plants and microgrids to smart markets. Digital technologies and new business models are transforming the relationship between energy producers and consumers. Experts at the conference are set to examine what the energy market of the future will look like, among other topics. On the first day of the event, they will present examples and trends, such as how private, commercial and industry customers can optimize local resources. The second day has presentations in store to share expertise on developments and business opportunities for linking decentralized energy resources with the power grid.

Photovoltaics from every angle

The focus will be on markets, technologies and financing for PV projects at the Intersolar Europe Conference. As well as market development in Europe, this year experts will particularly be shining a light on markets in Africa and in the MENA region (Middle East and North Africa). The International Energy Agency (IEA), for example, is organizing a workshop on the performance and operational reliability of PV, as well as PV systems operations and maintenance. Further sessions will cover the interaction of PV and storage. Participants will also discover valuable information about new applications of solar installations, in façades, on agricultural land and on water.

Everything there is to know about energy storage

The ees Europe Conference offers orientation on battery systems and stationary energy storage systems – covering markets, financing, business models, production technologies and safety aspects.

The technology group Wärtsilä has been the pioneer to promote flexibility in energy systems to enable greater use of solar and wind power. The company’s Smart Power Generation solution was launched ten years ago in recognition of growing environmental awareness within the industry, and in anticipation of increasing adoption of energy from renewable sources. As the energy industry transformation accelerates, with traditional baseload plants unable to efficiently cope with the new realities, Wärtsilä’s vision is being endorsed with an increasing market share in the <500 MW market segment, growing from 13 percent in 2016 to 19 percent in 2017, according to the McCoy Power Report. The cost competitiveness of wind and solar power is rapidly increasing. For example, the cost per kW of wind power plants has dropped by 40 percent during the past 20 years, while the cost per kW of solar plants has dropped by more than 90 percent during the same period. Consequently, renewables currently represent one of the cheapest ways to produce electricity in areas with good wind and solar conditions, making them viable without the need for government subsidies. Today, wind and solar power plants produce approximately 1,100 GW of electricity globally and forecasts indicate that this will increase to 2,000 GW by 2024. That flexibility is essential in systems using energy produced by wind and solar is today an unchallenged fact. Wärtsilä’s approach, with its Smart Power Generation solution, provides the ability to go offline and restart quickly, multiple times per day, while its energy storage capabilities serve to smooth variations in supply and store excess power from renewables. “Wärtsilä’s share of the global power plant market is growing because we have successfully established ourselves as a systems integrator and service provider in this changing world. We can offer not only power generation assets, but also storage and integration software solutions, as well as operations, maintenance and lifecycle optimisation of the assets,” says Javier Cavada, President, Wärtsilä Energy Solutions.

Recent examples of the role that Wärtsilä’s Smart Power Generation is playing in this energy transition include two power plants ordered by the Upper Michigan Energy Resources Corporation in the USA. They will accommodate a broad range of operating profiles for which flexibility is a prime requirement. In Arizona, Tucson Electric Power (TEP) is building a 200 MW Wärtsilä Smart Power Generation plant to provide the needed flexibility for integrating more wind and solar into its system. AGL Energy Ltd, one of Australia’s leading integrated energy companies, recently ordered a 211 MW Wärtsilä plant to provide the reliability and fast-starting capability required to enable increased levels of energy from renewable sources.

Digital technologies for fossil fuel operation and maintenance are big business today, but activity is shifting towards services for distributed renewables and the connected home. New energy innovations will be centered on digital technologies and the strategic use of data, according to new research published today. A shift is coming in the energy industry from a focus on hardware to the increased importance of software in order to make systems more efficient, resilient, and digital.

Digitalization of Energy Systems, a report by Bloomberg New Energy Finance (BNEF), predicts significant shifts in the intelligence of digital technologies used in energy from today to 2025, and a big change in the sectors of the energy system that most benefit from these technologies.

Today, the biggest use of digital technologies like sensors, data collection and analytics in the energy sector is to improve the bottom line of fossil fuel generators. Revenue for digital services for fossil fuel operation and maintenance, or O&M, are estimated to be $24 billion in 2017 – some 44% of the total market size for digitalization measured by BNEF.

However, as natural gas and coal plants come offline, and those that remain become digitalized, the opportunities for new revenues from the fossil fuel sector will shrink. By 2025, digital technologies will be more intelligent and more capable, helping home owners that own rooftop solar, batteries or EVs (often termed ‘prosumers’), to become more autonomous and derive greater value from these assets. This could be through trading energy with neighbors or better management of peak power prices.

Home energy management technologies will see the most significant change in digital revenues, rising from $1 billion in 2017 to $11 billion in 2025. The largest driver for digital technology revenues in 2025 will be smart meters, growing 44% between now and 2025, to $26bn. This revenue increase matches the fall in digital revenues from fossil fuel O&M – 46% over that time period.

Digital technologies like big data, analytics and machine learning, blockchain, distributed energy resource management, and cloud computing, can help overcome some of the key challenges in the energy sector – most notably intermittency, aging grids, balancing distribution-connected generation, managing consumer self-generation, and coping with increasing system complexity.

Countries with high penetration of distributed renewables, good communications network infrastructure, and robust venture capital investment in digital technologies are likely to take rapid advantage of energy digitalization. Italy, for instance, is one of the global leaders in small-scale PV, has almost 100% high speed network coverage, and supportive regulation for digital technologies.

The U.S. will also do well, having long been a leader in digital technologies and early-stage fundraising. Australia, although ranking lower today, will move near the top of the group in 2025 due to high forecast levels of decentralized energy production. In emerging markets, countries that have beneficial government policies, foster innovative start-ups and are rolling-out network infrastructure are likely to digitalize soonest – for example Chile, Indonesia and Nigeria.

The motivation for industry digitalization will be different for each player. Generators and ‘prosumers’ are motivated by cost reduction, additional revenue streams and new services. Utilities face pressure from customers, government policy and regulation to improve their businesses. They can use digitization to streamline operations and enhance customer services.

The power sector has traditionally been served by large industrial companies selling primarily hardware, but innovation is increasingly centered on software and advanced technologies such as machine learning. Whether the winning solutions will come from industrials, start-ups, or technology companies remains to be seen.

Just days ago, Vestas reported a historical record year. With a revenue of more than €10bn and a net profit of €965m in 2016, 41% more than in the previous year, it has an unparalleled global presence in the wind industry. Despite fierce competition and the challenges inherent to the energy industry, Vestas has maintained its leadership with 82 GW of installed capacity in 76 countries worldwide.

Latin America is one of the regions where Vestas is making a strong bet. Having consolidated its leadership in mature European markets such as Italy and France and having managed to position itself as the leading manufacturer in terms of installed capacity and number of new orders in the US last year, there is no let-up for Vestas. The company continues to lead an industry at global level that, as its chairman, Bert Nordberg, stated in the company’s annual report, “together with other sources of clean generation, will lead the future of the energy industry”.

 

Within this context of growth, Latin America has become a key region. During recent years, many countries on the American continent have jumped on the renewables band waggon, promoting green policies and supporting more efficient mechanisms to allocate electricity capacity, such as power auctions. This phenomenon has resulted in the majority of the orders secured in 2016 being concentrated in the second half of the year. Countries such as Chile, Mexico, Brazil and Argentina all held renewable energy auctions last year and some of the projects already awarded still have to materialise. Read more…
