Acciona has begun construction work on the 64-MWp Usya photovoltaic plant, the third owned by the company in Chile. Acciona is currently constructing almost 400 MW in Chile in two wind farms and two photovoltaic plants, which will enter service in late 2019/early 2020.

 

The Usya plant, located in the municipality of Calama (Antofagasta region), will have a maximum capacity of 64 peak megawatts (MWp) -51 MW rated capacity- and an estimated annual emission-free energy generation of 146 GWh, equivalent to the electricity demand of around 70,000 Chilean households.

The new photovoltaic plant will be equipped with 187,200 modules mounted on fixed structures, which will be installed on a surface area of 105 hectares. The plant is expected to enter service in mid-2020.

Around 400 people will work in the project during the period of highest construction activity. After it enters service, the new plant will avoid the emission of around 141,000 T of CO2 to the atmosphere from coal-fired power stations.

Other plants in Chile

Acciona is currently building three other renewable energy facilities under its ownership in Chile, two wind farms in La Araucanía totalling 267 MW and a 62-MWp photovoltaic plant in Atacama, which will join the 291 MW already in service in the country.

The company’s construction effort will lead to a total of almost 700 MW of renewable capacity under its ownership in Chile by 2020, with an investment of around 1,000 M.

With a volume of more than 4 GW of capacity shipped in 2018 and more than 12 GW of total capacity installed all over the world, in 2018 GoodWe became the 7th largest supplier of PV inverters on a global scale. That is according to a recently released report by Wood Mackenzie and titled Global Solar PV inverter market: Market shares and shipment trends 2019.

This is not the first time that according to an authoritative international institution GoodWe makes it to the list of the largest suppliers of PV inverters (IHS and Bloomberg on previous years have also identified the company a major supplier).

According to the report: in 2018, the GoodWe shipments of PV inverters reached 4% of the global market share. In two large solar markets, Europe and Asia-Pacific, GoodWe maintained an outstanding performance: last year, GoodWe supplied 3% of the inverters acquired by the European market, which made the company the top 10 largest supplier of this continent. In Asia-Pacific, GoodWe reached a 5% of the market share, making othe company the 4th largest supplier, which is remarkable given the volumes involved and the size of the national markets of this region, that include the largest world markets of China and India and the sophisticated market of Australia.

The year of 2018 was very challenging for the Chinese solar industry, but GoodWe still managed to expand in the global market and the inclusion of our company on the Wood Mackenzie top ten list bears witness to those efforts. It is also worth mentioning that the more than 4 GW volume shipped by GoodWe last year was 35 times more than what we shipped in 2012 and more than double of what we shipped in 2016. The Wood Mackenzie report fully illustrates that despite the challenges of last year, GoodWe has managed to maintain a remarkable high rate of annual growth that since 2012 has averaged 100%.

Across the world the solar industry is experiencing a fresh wave of growth and the demand has continued to expand and diversify. The quality expectation of consumers around the world has become more complex and the inverter suppliers are forced to innovate and deliver value to meet the rising demand and excel amid fierce competition. GoodWe’s competitors are formidable companies and being part again of the big leagues is not a small feat in these times of rapid evolution.

The continuation of GoodWe on the selected group of the world top largest PV inverter suppliers rests on several factors. Three of them stand out: GoodWe has understood that service is of critical importance to win customers trust and satisfaction and as such it has set up local service teams in Europe, Latin America, India, Australia, Korea and other markets. The expansion seen over the past year of the GoodWe businesses across the world is just a reflection of those efforts. Another factor is that GoodWe is distinguished by its capacity to react quickly to the customer demand, something that has been allowing the company to improve its products over significantly short periods of time. Last but not least, it is worth mentioning the wide and expanding portfolio of GoodWe products that allow the company to cater to different market segments and within these, meet the quality expectations of different kinds of customers.

European electricity markets

Since April 1, prices in Europe have had certain stability. The rise in the CO2 emission price was offset by lower gas and coal prices and also by the slight decrease in electricity demand due to the better weather conditions in spring, with somewhat higher temperatures and more hours of sunshine in this 40-day period. The price fluctuations in this period are mainly due to variations in wind energy production, especially in Germany and Spain, which are the European leaders generating energy with this technology. In the case of Germany, prices could have been stable at 40 €/MWh but when there was a lot of wind they fell below this value, even reaching negative values on April 22 at 14 €/MWh. In the Spanish electricity market, fluctuations in wind energy production caused prices in the band between 40 €/MWh and 60 €/MWh. Also in this period of 40 days there were fluctuations in temperature and in solar energy production.


Electricity futures

The prices of European electricity futures for the third quarter of 2019 increased in most markets between 0.3% and 1.6% on Friday, May 10, compared to Friday of previous week. In the case of the OMIP market of Spain and Portugal, as well as the MTE market operated by GME, they remain unchanged, while the UK futures decreased in both the ICE and EEX markets.
In the case of futures for 2020, the increase was more widespread between 0.5% and 1.4%. Only the MTE market operated by GME remained unchanged and the UK’s ICE and EEX markets declined, as did the future for the third quarter of this year.

Wind and solar energy production

In the second week of May, the wind energy production had an increase in the main European markets except in Germany with a drop of 3.3%. The increase in France was 58%, in Portugal 99%, in Spain 36%, and in Italy 37%.
For the current week, the third of May, a decline in wind energy production is forecasted after the rise of the previous week. The most pronounced fall is expected in Italy and Portugal, somewhat less in Spain and France, and even a slight increase in Germany.

As for solar energy production, which includes photovoltaic and solar thermal technologies, during the second week of May fell by 4.3% in Germany, while in Spain the fall reached 20% with respect to the previous week. For its part, in Italy the previous week registered an increase of 5.3% in the solar energy production.
For the current week it is expected a decrease in solar energy production in Italy of about 20%, while in Germany and Spain the trend is expected to be bullish between 15% and 20%.

China’s Huawei Technologies Co Ltd has established a team in Spain for its solar string inverter division, Huawei FusionSolar, in a bid to seize opportunities in the country’s growing PV market. Huawei has said that Spain would be the priority market for the business unit, which already has a team of 15 in the sales and pre-sales departments.

Last year, Spain installed 261.7 MW of new PV capacity, a 94% increase compared to the previous year and up by 500% compared to the 2016 installations, Huawei said citing data by the Spanish Photovoltaic Union (UNEF). The Spanish PV market could grow up to, or even surpass, EUR 5 billion (USD 5.7bn), the Chinese company added.

In 2018, engineering, procurement and construction (EPC) firm Grupotec selected Huawei as the supplier of string inverters for a series of Spanish solar projects with a combined capacity of 168 MW. Huawei expects to negotiate new contracts in Spain throughout the year eyeing an order volume of more than 3 GW. It also intends to grow its business through government-awarded projects and power purchase agreements (PPAs) with private companies, as well as offer solutions for self-consumption schemes.

The PV resource has a great future in southern Europe. The regions of the southern part of the European continent can become developed areas with knowledge-based industries thanks to photovoltaic energy in the future.

Some people are born in a poor country, others in a rich country. Some are born in a region with a high level of education or in one with very few resources, rich or very poor cities. What determines the destiny of a country or a region? An important factor is natural resources, well managed, with investments in infrastructure and investments in knowledge. Can a poor country change in a few years thanks to well-managed natural resources? Dubai is an example. Thanks to the oil fields, the country has taken a leap into the future from the depths of poverty. A country with well-managed energy resources can advance unlimitedly.

The photovoltaic technology has been lowering the prices of the solar panels until reaching the threshold of profitability, being able to sell the energy directly in the market without incentives.

The southern regions of Europe are generally the least developed. However, nature has provided them with the best energy resource, solar energy. Thanks to photovoltaic technology and the large number of hours of sunshine in the south of the continent, more than 2,000 hours, southern Europe is an inexhaustible mine of clean energy.

Together with wind and hydroelectric energy, photovoltaic energy will replace polluting fossil energies, first coal and then gas. They will also replace nuclear energy. Fortunately a cleaner future is possible. The electricity obtained from clean renewable sources will replace the rest of the energy in all areas: industry, domestic and transport.

The use of hydrogen will be extended in internal combustion engines and as an energy source in electrochemical cells. The transport of the near future will be electric, with batteries or hydrogen batteries. A cleaner atmosphere will be achieved and also cities without air pollution and without transport noise.

What will happen to energy prices? It can be thought that a technology that uses photovoltaic solar energy, with increasingly low prices and also low maintenance costs, will cause the market price of electricity to fall.

At AleaSoft we believe that in the next 20 years a market balance will be maintained in Europe. The renewable energies will be replacing the non-renewable but also the electricity demand will increase. In Spain, according to an analysis performed by Red Eléctrica, for each million electric cars the demand will increase by one percent. But in the case of transport, we are not only talking about electric cars, but all kinds of land and sea electric transport. The ships of the future will have as fuel the hydrogen that is manufactured with electricity.

The nearby sources of energy are a claim for the installation of new productive infrastructures. Photovoltaic self-consumption will be encouraged in the southern areas of Europe.

A new industry requires a lot of energy: the knowledge industry, artificial intelligence, massive servers, cloud-based systems, blockchain, big data, in short, the main industry of the future.

In the same way that Dubai, thanks to energy, has become a world reference for development, in the photovoltaic revolution many regions of the world are going to have an opportunity to grow and develop. In Southern Europe, all the conditions are settled so that the most disadvantaged regions can participate in this inexhaustible mine of energy resources.

European, national and regional administrations should encourage investments in renewable energy, mainly photovoltaics.

The company supplies solar trackers to two PV plants in the Brazilian state of Minas Gerais

Soltec has started to supply its trackers to two PV plants in the state of Minas Gerais, in south-east Brazil.

The municipality of Guimarânia will be home to approximately 2,800 SF7 Single-Axis Trackers that will be installed at one of the two solar plants. Soltec’s trackers will move nearly 250,000 PV modules to track the sun’s position in the sky for increased annual energy capture.

Project developer, Canadian Solar, EPC company Biosar and utility Global Power Generation (GPG) have teamed up with Soltec for this 82.5 MW project in Guimarânia. The plant is currently under construction and is scheduled to be operational by the end of December 2018.

At the same time, Soltec is also supplying its SF7 self-powered trackers to one of the largest distributed generation solar power plants in Brazil. Located in the municipality of Uberlândia, this plant will enter into operation this month.

Alsol Energias Renováveis, whose activity comprise developing renewable energy projects for companies and private individuals, chose Soltec’s trackers and the reliability of its supply for this 5 MW PV plant.

“Customers know that our experience and leading position as solar tracker supplier in Brazil make Soltec a safe bet”, says Raúl Morales, CEO of Soltec. “Soltec’s market leadership in the country has already been clearly demonstrated and is largely due to our ability to supply equipment at an astonishing rate”.

In order to cover the costs of the company’s commercial expansion that started in 2014, the year in which it launched its international trajectory by signing its first supply contract for a utility-scale solar plant, Soltec has agreed a loan for 100 million Euros in order to continue with an internationalisation process that has enabled the company to undertake projects and open subsidiaries on the five continents.

The financing has been headed up by Banco Santander, with consultation from PwC, and has involved Spain’s leading financial entities: Bankia, Bankinter, BBVA, Caixabank, Cajamar CajaRural, Ibercaja, Liberbank, Sadabell, Banco Cooperativo Español and Banco Pichincha España. Throughout the entire process Soltec has benefitted from the collaboration of Garrigues on legal matters.

Syndicated loans are a special financing method, defined by the joint intervention of several credit institutions that agree to authorise a loan which, due to its high amount, requires the cooperation of several financial institutions.

“We are grateful for the confidence that these financial entities have placed in us,” comments Morales. “This loan will allow us to continue supplying solar trackers to the increasing number of PV projects in which Soltec is involved in countries as diverse as Brazil, Egypt and Spain”.

Soltec’s global operations and a workforce of over 750 people bring together experience and innovation. Soltec has manufacturing centres in Brazil, China and Spain; and offices in Australia, Denmark, Chile, Egypt, the US, India, Israel, Italy, Mexico and Peru.

With a firm commitment to renewable energies and the environment, Soltec supports product standardisation and the success of its clients.

The future of the energy system depends on whether we develop solutions that provide flexibility to efficiently integrate renewable energy sources. Intelligent building technology is the key to success. The joint venture planned by SMA and Danfoss aims to provide supermarket operators with an integrated solution that interconnects cooling and refrigeration technology, photovoltaics, energy storage technology and e-mobility. Intelligently managing loads and integrating the overall system into the energy market allows supermarket operators to reduce their operating expenditure, optimize their carbon footprint and considerably improve their long-term competitiveness. In addition, they will become a key component of the energy system of the future.

“Our expertise in photovoltaics, battery-storage systems and energy management is a complementary fit with Danfoss’ long-standing experience in cooling and refrigeration technology and its access to customers in the food retail segment,” said Dr.-Ing. Jürgen Reinert, Board Member for Operations and Technology of SMA Solar Technology AG. “I am delighted that this planned joint venture will allow us to further expand our strategic partnership with Danfoss.”

“The food retail segment is both of strategic importance and a playing field for innovation,” said Jürgen Fischer, President of Danfoss Cooling. “Innovative products from cooling and heating technology combined with photovoltaics, energy storage and charging stations will be used in the supermarket of the future. Supermarkets will not only provide fresh goods, but also transform the utility grid, which will become more reliable, greener and more flexible. Danfoss and SMA are very well positioned to tap into this new market. As part of this planned joint venture, headquartered in Hamburg, Germany, we will work together to develop our tried-and-tested technology and secure ourselves a leading market position in this segment.”

SMA’s newly founded subsidiary, Coneva GmbH, will cooperate with Danfoss’ Cooling Segment to design a service offering tailored to the individual requirements of the food retail segment. “The SMA energy management platform ennexOS is an ideal tool for optimizing the energy consumption of retailers using parameters like the current electricity prices, outside temperature, solar irradiation and temporary grid requirements,” explained Jochen Schneider, general manager of Coneva GmbH. “Surplus self-generated electricity can either be sold directly or stored in electric and thermal storage systems. The integration into the energy market also allows us to secure the supply of cost-effective, environmentally friendly energy. In addition, we can integrate charging stations.

The planned joint venture is likely subject to the approval of competent antitrust authorities.

Over the last few years, there has been a marked increase in the number of installations made in desert environments. This is due to the fact that deserts offer vast tracts of land at relatively cheap prices and with a large number of sun hours, making it possible to reduce the cost of solar energy. At the same time, the market-led reduction in PV system costs has led to the use of outdoor solutions that dispense with external housings to protect the inverters and other equipment at the transformer substations (transformers, medium voltage cells, etc.). Therefore, there is a need to guarantee the correct operation of this equipment in these extreme operating conditions yet with no performance losses.

Ingeteam’s two main PV inverters have both been certified to the IEC 60068-2-68 international standard by an external laboratory. This standard establishes the conditions to be met by electronic equipment in order to effectively operate in environments with high concentrations of dust and sand.

The certificate was obtained for Ingeteam’s central inverter which is part of the INGECON SUN PowerMax B series and also for its very latest 100 kW string inverter, which is part of the INGECON SUN 3Play family. In both cases, the tests conducted demonstrated that the ingress of particles inside the equipment was residual and did not affect the normal inverter operation or performance.

In order to conduct the sand and dust tests based on the IEC 60068-2-68 international standard, Ingeteam acquired a climatic chamber for sand and dust tests, certified under the international standard UNE-EN 60068-2-68: 1997. This sealed chamber is able to create a controlled atmosphere with the humidity, wind velocity and sand concentration conditions required by the standard. For this purpose, the chamber is equipped with two particle blowers that continuously blow sand against the inverter and create an atmosphere with a specific concentration of sand and dust in suspension. Furthermore, the sand used is of similar characteristics to that found in a desert, with regard to grain size (between 0.14 and 0.59 millimetres) and composition, with a predominance of quartz, olivine and feldspar, as it is specified in the regulation.

This sand chamber, capable of testing equipment of the dimensions of a central PV inverter, was used to verify the correct operation of the inverters, as well as the efficiency of its “sand trap” system to prevent the ingress of particles into the B series central inverter, while collecting the grains of sand and facilitating their subsequent removal. Moreover, the new inverters feature a system that completely seals the ventilation circuit, for maximum protection against the ingress of particles, which could cause serious technical problems in converters installed in the desert. Therefore, as well as the tests specified in the certification procedure, Ingeteam also subjected its equipment to even more extreme conditions, such as those characteristic of a desert sandstorm, clearly demonstrating that its outdoor equipment is able to withstand situations with a high concentration of particles in the air (100 g/m3) and high wind speed (160 km/h).

Thanks to this achievement, Ingeteam has strengthened the company’s position as a power converter manufacturer specialising in the provision of technical solutions for plants located in hostile environments.
