The renewable energy sector in Brazil has high expectations for growth in the coming years. By 2024, solar power will account for 4% of Brazil’s energy matrix, and wind power will be the second-largest energy source by 2020, accounting for 12% of production, according to the Brazilian Photovoltaic Solar Energy Association (ABSOLAR) and the Brazilian Wind Energy Association (ABEEólica). Solar energy currently accounts for 0.02% of the energy matrix and wind for 6%.

Following this trend, GE’s Power Conversion business has just completed domestic content compliance for its solar and wind inverters—the LV5 and DTA CFI lines, respectively—following the rules set out by Brazil’s state-owned development bank, BNDES, regarding how much of the equipment is manufactured in Brazil. This means Brazilian clients can get BNDES credit at more attractive interest rates.

Following the GE Store concept—offering a complete solution for clients through different businesses owned by the company—compliance with BNDES requirements by wind frequency inverters, which are installed inside wind turbines, met a specific demand from GE’s wind division, which took an active part in the entire process.

GE has been pioneering 1,500-volt LV5 solar inverters that bring high cost-effectiveness to utility solar farms. Since the launch of its 1,500-volt inverters in 2014, GE has delivered more than 1 GW and accumulated a further 4 GW in backlog globally. Now that the inverters have obtained BNDES accreditation, it opens the avenue for us to continue to deliver value also to Brazilian customers and local solar farms.

Siemens and Gamesa have signed binding agreements to merge Siemens’ wind power business, including wind services, with Gamesa. Siemens will receive newly issued shares of the combined company and will hold 59% of the share capital while Gamesa’s existing shareholders will hold 41%. As part of the merger, Siemens will fund a cash payment of €3.75/share, which will be distributed to Gamesa’s shareholders (excluding Siemens) immediately following the completion of the merger (net of any ordinary dividends paid until completion of the merger). The cash payment represents 26 percent of Gamesa’s unaffected share price at market close on January 28, 2016.

Additionally Gamesa and Areva have entered into contractual agreements whereby Areva waives existing contractual restrictions simplifying the merger between Gamesa and Siemens. As part of these agreements, Gamesa grants Areva a put option for Areva’s 50% stake and a call option for Gamesa’s 50% stake in Adwen. Both options expire in three months. Alternatively, Areva can in this time divest 100% of Adwen to a third party via a drag-along right for Gamesa’s stake.

The new company, which will be consolidated in Siemens’ financial statements, is expected to have on a pro forma basis (last twelve months as of March 2016) a 69 GW installed base worldwide, an order backlog of around €20 billion, revenue of €9.3 billion and an adjusted EBIT of €839 million. The combined company will have its global headquarters in Spain and will remain listed in Spain. The onshore headquarters will be located in Spain, while the offshore headquarters will reside in Hamburg, Germany, and Vejle, Denmark.

The two businesses are highly complementary in terms of global footprint, existing product portfolios and technologies. The combined business will have a global reach across all important regions and manufacturing footprints in all continents. Siemens’ wind power business has a strong foothold in North America and Northern Europe, and Gamesa is well positioned in fast-growing emerging markets, such as India and Latin America, and in Southern Europe. Further, the transaction will result in a product offering covering all wind classes and addressing all key market segments to better serve customers’ needs.

Siemens and Gamesa expect significant synergy potentials in a combined setup. In total, annual EBIT synergies of €230 million are expected in year four post closing.

The envisaged combination is unanimously supported by Gamesa’s Board of Directors and Siemens’ Supervisory Board. Iberdrola has entered into a shareholders’ agreement with Siemens and will hold around 8% in the combined company after closing of the transaction. The transaction is subject to the approval by Gamesa’s shareholders and to other customary conditions such as merger control clearances and the confirmation by the Spanish stock market regulator (CNMV) that no mandatory takeover bid has to be launched by Siemens following completion of the merger. Supervision of the merger process has been entrusted by Gamesa to a merger committee created ad hoc, which will be made up exclusively of independent directors. Closing is expected in the first quarter of calendar year 2017.

Ereda has undertaken a project that aims to analyse the possibility of limiting the cost of the energy supply to a medium-sized industrial plant, with an installed capacity of over 26 MW, located in the south-west of Kazakhstan. The cost of electricity for its processes accounts for an important part of its production cost, achieving values in excess of 40%. The price of electricity in the country is
expected to rise over the coming years. In addition, the plant is now required to reduce CO2 emissions from its industrial activity, which is why a further cost arising from the acquisition of emissions rights is expected in future. The sequence and activities undertaken were as follows:

Estimate of the wind and solar resource by means of a numerical simulation. Ereda has its own computational cluster and uses the WRF model, one of the most widely-used in the scientific community and by meteorological services worldwide. These tools are used to carry out an estimate of the expected wind and solar resource at the site with a longterm projection. Its main characteristics are illustrated in the following graphs.

Energy pattern analysis of the industrial plant. One of the features of the plant’s production processes is that they are uninterrupted meaning that there is a significant level of consumption both day and night. One part of that load can be moved as appropriate and in fact, this has been taking place to make use of the best hourly electricity tariffs offered by the utility company to clients with
differentiated hourly tariffs. Seasonally the variation is not very significant, despite the existence of a high and a low consumption season. Read more…

    In 2014 the top 3 countries by installed wind power capacity were China, the USA and Germany, ranked first to third in that order with cumulative installed capacities of 114,763 MW, 65,879 MW and 40,468 MW respectively. The three wind power employers’ associations of each country have already published preliminary data on installed capacity in 2015, revealing that China has maintained its leadership in terms of both added and cumulative capacity with an additional 30.5 GW over the year. The USA closed 2015 with almost 8.6 GW installed over the course of the year. Germany, with separate figures published for onshore and offshore wind power, has closed with a total of 5.8 GW of newly installed wind power of which 3.5 GW corresponds to onshore and 2.3 GW to offshore.

    China continues to be the world’s largest wind power market in terms of both new and cumulative installed capacity. The country achieved a new installed wind power capacity of 30.5 GW in 2015, representing a significant growth of 31.5% on 2014 with 23.3 GW installed, according to statistics released by the Chinese Wind Energy Association. This increase was mainly due to a policy lowering the country’s feed-in tariff for wind power in 2016.

    The country’s wind power market is dominated by domestic players, with 23 Chinese wind power companies accounting for a combined market share of 97%. For the fifth year running, Goldwind Science & Technology was the leading operator by installed capacity with over 7 GW, followed by Envision Energy, Mingyang Wind Power, United Power and CSIC (Chongqing) Haizhuang Windpower Equipment.

    Gamesa and CAF have joined forces to become core shareholders, each with a 50% interest, in the technology player, NEM Solutions. Together they will support this company’s continued development and make it a cornerstone of their operations and maintenance strategies. NEM Solutions specialises in the application of technology in maintenance activities in the wind and rail sectors; specifically, it leverages data mining to optimise equipment (wind turbines, trains) performance by anticipating future incidents.

    This transaction is part of Gamesa’s goals for developing services which add significant value for the customer in the predictive maintenance arena, as announced in its 2015-2017 Business Plan, by reinforcing its commitment to state-of-the-art technology in order to enhance turbine performance and streamline maintenance processes and costs.

    To structure this transaction, which is subject to anti-trust approval, Gamesa is acquiring a 50% shareholding in NEM Solutions, to which end it is purchasing Tecnalia’s entire 15% interest and 35% of CAF’s shareholding (CAF is reducing its stake to 50%). The transaction is expected to close in the first quarter of 2016.

    “The investment in NEM alongside a partner of the calibre of CAF will accelerate Gamesa’s access to advanced data management know-how in the predictive maintenance field, a powerful technology tool which is not as developed in the wind sector as in the rail industry”, said David Mesonero, Corporate Development Managing Director of Gamesa.

    NEM Solutions develops technological applications for the management of predictive maintenance in the wind and rail sectors. Through its technology platform, AURA, the company analyses the millions of data points generated by the equipment under maintenance with a view to creating a model that defines normal operating conditions for each piece of equipment. Based on this benchmark, it predicts the future performance of each machine, diagnosing, precisely and proactively, using artificial intelligence, potential equipment incidents.

    In the specific case of Gamesa, the systems developed by NEM will use the 15.5 billion data inputs generated and sent daily by the more than 14,500 turbines under its maintenance (20,600 MW) to the company’s remote control centre in Sarriguren (Navarre, Spain).

    Siemens is strengthening its collaboration with Norwegian company Statoil on floating offshore wind turbines. For the 30 megawatt (MW) Hywind Scotland Project, Siemens will supply five of its SWT-6.0-154 direct drive offshore wind turbines.

    The turbines will be installed on floating foundations operating in water depths between 90 and 120 meters. The world´s largest floating wind project is located in Scottish waters 25 kilometers off the coast of Peterhead in Aberdeenshire. For the new Hywind Scotland Project, assembly in West Coast Norway is scheduled for first half 2017. In 2009 Statoil and Siemens successfully installed a 2.3 MW Siemens turbine at the first floating full-scale wind project worldwide, Hywind Demo.

    This Scottish pilot project demonstrates how future floating concepts for commercial and large scale offshore wind parks can be both cost efficient and low risk. The floating foundations are ballast-stabilized and fastened to the seabed with mooring lines. With their lightweight nacelles, Siemens large direct drive wind turbines are particularly suited for the floating foundations designed as slender cylinder structures.

    floating-wind-farm-full-276This concept has already proven its effectiveness in the 2009 project. At the same time Siemens gathered a lot of experience on the specific requirements regarding the control parameters on a moving wind turbine under offshore conditions. For the floating installation Siemens’ technicians developed new controller settings for rotor pitch and yaw drive regulation.

    “We are proud to once again be on board the floating wind project with Statoil, and to apply the experience we gained with the first full scale floater,” said Morten Rasmussen, Head of Technology at Siemens Wind Power and Renewables Division. “Hywind Scotland is another pioneering project and has the potential to become a trailblazer for future floating wind projects.” WorldslargestWP1-bajaIn the joint project Siemens and the Norwegian energy company Statoil installed a Siemens SWT-2.3-82 with a 65 meter hub height on a ballast-stabilized floating structure. An enlarged version of this structure serves as the basis for the new Hywind Scotland project, which contains five SWT-6.0-154 wind turbines with a hub height of 103 meter each.

      Some days ago, ground-breaking ceremony officially kicked off construction of the 117 MW wind power plant, which will produce clean electricity at half the cost of Jordanian conventional power.
      Tafilah is the combined result of a four-year cooperation by a team of Jordanian and international experts. Civil works have already begun, and the 38 wind turbines will be directly transported from the port of Aqaba to the project site over the coming months. The first turbines will begin to produce electricity as from the first quarter of 2015, and the wind power plant will be fully operational by August 2015.
      The wind power plant will then be connected directly to the National Electric Power Company grid and provide almost 400 GWh of electricity per year, enough to meet the energy needs of over 150,000 Jordanians. The Al Tafilah project will also significantly contribute to the region’s development by providing jobs to 150 people during construction and 30 during its operation.
