Power plant controller made by meteocontrol is managing the largest zero-feed-in PV system in Turkey Augsburg/Ankara/Antalya, April 04, 2018 – As a cooperation partner of the Turkish EPC service provider Altungrup Solar Enerji, who is specialized in rooftop solar installations, meteocontrol GmbH has developed the monitoring and control concept for the largest zero-feed-in PV project in Turkey. The 400 kWp rooftop system provides 90 percent of the power needed each day to run the warehouse operated by Reysaş REIT in Antalya. The power plant controller made by meteocontrol manages the inverter's power in response to energy needs: If power production begins to exceed demand, the system is slowed down. Reysaş REIT is committed to solar energy: The leading provider of warehouses and logistics facilities in Turkey has been installing photovoltaic systems on its warehouses for five years now. In the beginning, the company fed the energy generated by the systems into the Turkish power grid. As a result of grid feed-in regulations, the investor has shifted the focus of newly installed PV systems to solely on-site energy consumption. The first and largest zero-feed-in PV system in Turkey was installed on a warehouse in Antalya. The roof unit erected by Altungrup Solar Enerji

• The Dam Nai wind farm will be equipped with 15 SG 2.6-114 turbines, with total capacity of 39 MW Siemens Gamesa Renewable Energy (SGRE) continues to reinforce its presence in Vietnam where it will install and commission the Dam Nai wind farm with 39 MW for the independent operator, The Blue Circle, headquartered in Singapore. Development of this project has been divided into two phases: phase one, in which Siemens Gamesa last year installed three SG 2.6-114 turbines that are already operational; and phase two, signed now, in which the company will furnish the remaining 12 turbines for commissioning by October of this year. Siemens Gamesa will also handle the operations and maintenance services at this facility, located in the southern Vietnamese province of Ninh Thuan, for the next 10 years. Constrained by the strong winds that kick up in this region from around October, the deadline between the contract's execution and the commissioning of the wind farm is very tight, demonstrating once again the company's ability to adapt to its customers' tailored requirements on a project by project basis. “We are committed to Vietnam as a market and we want to be our customers’ preferred partner in developing wind power projects”, highlighted Álvaro

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with the company EV Group (EVG) have developed a new silicon-based multi-junction solar cell, which can convert exactly one-third of the incident sunlight into useful electricity. This newest result is now published in the renowned scientific magazine Nature Energy. Silicon solar cells dominate the global photovoltaic market today with a share of 90 percent. With ever new technological developments, research and industry are nearing the theoretical efficiency limit for semiconductor silicon. At the same time, they are forging new paths to develop a new generation of even more efficient solar cells. The Fraunhofer researchers achieved the high conversion efficiency of the silicon-based multi-junction solar cell with extremely thin 0.002 mm semiconductor layers of III-V compound semiconductors, bonding them to a silicon solar cell. To compare, the thickness of these layers is less than one twentieth the thickness of a human hair. The visible sunlight is absorbed in a gallium-indium-phosphide (GaInP) top cell, the near infrared light in gallium-arsenide (GaAs) and the longer wavelengths in the silicon subcell. In this way, the efficiency of silicon solar cells can be significantly increased. “Photovoltaics is a key pillar for the energy transformation,” says Dr. Andreas Bett,

WinGD and Wärtsilä Gas Systems have successfully tested a NG-VOC (Natural Gas - Volatile Organic Compounds) fuel mix for the WinGD X-DF engine, selected to power two 125 000 dwt Shuttle Tankers for AET. Guests from AET, Statoil, OSM Maritime Group, Samsung Shipyard and Hyundai Heavy Industries-Engine & Machinery Division were on hand in Trieste, Italy, in March, to witness the successful test of a WinGD X-DF engine running on a NG-VOC mix. The test demonstrated the engine’s capabilities under various load scenarios with up to 20% VOC in the fuel ratio. The engine sustained high performance throughout transfers from pure NG to a VOC mix, as well as transferring to diesel mode and back again.  Notably, while maintaining efficiency, NOx emissions remained significantly below IMO Tier III levels while operating on the NG- VOC mix. The capability demonstrated by WinGD in Trieste, and already specified by AET for its shuttle tankers, has considerable implications for both the oil and gas industry and the environment. VOCs are a waste product from crude oil handling and transport which represent both a hazard and a loss of revenue to oil and gas producers and shippers. Historically, they were either discharged into the atmosphere or

Figures show 2017 was record year for green energy Enough electricity produced to power all Scotland’s homes more than twice overThe amount of power produced by Scotland’s renewable energy industry grew by 26% between 2016 and 2017. Almost 25 terawatt hours – enough to power all Scotland’s homes more than twice over – were produced by the country’s fleet of wind, hydro, solar, biomass, tidal and green gas generators in 2017. New UK Government figures also show Scotland is punching above its weight in renewable energy generation, with 25% of all UK renewable electricity produced north of the border in 2017. Claire Mack, Chief Executive of industry body Scottish Renewables, said: “Scotland has an enormous renewable energy resource: our winds, waves, tides, rainfall and even our longer daylight hours are tremendous assets to the country, and renewable energy enables us to use them to produce direct economic and environmental benefits. “These figures show Scotland as a renewable energy powerhouse, producing more electricity than ever and transferring much of it to markets in the rest of Great Britain, all the time reducing carbon emissions from our power sector. “What’s also clear is that with a turnover of almost £5,500 million in 2016, renewable energy continues to more

 Revenue growth (+42%) driven by both energy sales and services  EBITDA growth (+43%) with positive price effect achieved for energy sales in Brazil  Net profit growth (x6.1) thanks to strong performance in the second semester  Very good visibility on 90% of the 1 GW of installed capacity targeted by end 2020 Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energies, announces today its results for the 2017 fiscal year. "As expected, the strong performance of energy sales in the second half of the year compensated for the slow first semester. Services activities also enjoyed good growth, although, at this stage, most of it was related to power plants we own. In 2017, success in the Brazilian and French auctions demonstrated our strength in our historical markets. We also broadened our horizons by winning our first contract in Africa and by successfully setting up our first solar installation for an isolated site. 2018 will be a year of consolidation of our backlog before we accelerate our capacity growth in 2019 and beyond ", comments Sébastien Clerc, Chief Executive Officer of Voltalia.
