• Siemens Gamesa increases its multi-brand presence in the U.S. with the repower of 362 Vestas wind turbines for a capacity of 240 MW at two Texas wind farms, increasing their power rating up to 7.5% • The company will also repower 210 units of legacy Bonus turbines at the 268 MW King Mountain Wind Energy Center in Texas Siemens Gamesa Renewable Energy (SGRE) announces that it has signed two agreements with a subsidiary of NextEra Energy Resources to repower 508 MW in the US at three wind farms in Texas, demonstrating once again its strong multi-brand technical capabilities. Under the first agreement, the company will repower 362 units of Vestas’ V47 wind turbines at the Indian Mesa and Woodward wind farms in Texas. The V47 overhaul features a hardware and control upgrade resulting in an increased output of 710 kW from 660 kW and higher availability for 10 additional years beyond the original design life. The project is expected to be complete by year-end and the sites will remain operational during the installation by Siemens Gamesa. “We highly value our continued partnership with NextEra Energy Resources,” says Mark Albenze, CEO of Siemens Gamesa’s Service Business Unit. “As a multi-brand service provider, we can

For companies involved in waste management, spontaneous fires are a fact of life and the critical issue is therefore to detect an outbreak as efficiently as possible and prevent it spreading. For one such company in Sweden, FLIR thermal imaging cameras have played an essential role in this effort since 2016. Jönköping Energi turns up to 160,000 tons of waste per year – or 20 tons an hour – into heat and electricity, sufficient to cover the annual needs of 25,000 households. Preventing and controlling fires is not only a matter of safety but also of economics. “We have trucks bringing in waste not just from the surrounding area but from all over Europe which is dumped in a waste bunker, mixed by automatic cranes and stored awaiting transportation to the boiler,” explained Plant Manager, Magnus Olsson. He continued: “These waste piles can be a dangerous mix. Spontaneous combustion from biological products or other heat sources is a continual threat that needs to be monitored 24/7. Apart from the environmental consequences and obvious safety risks, an outbreak of fire can be very costly, up to £100,000 per day. That’s why it is so important to have a reliable early warning system.”

The Fraunhofer Institute for Solar Energy Systems ISE and teamtechnik, an international leader in production technology, report that it is now possible to connect high efficiency solar cells using electrically conductive adhesives in series production. The results of the joint research project »KleVer« show that the adhesive technology is ready for the market and can be used as an alternative to the widespread soft soldering interconnection technology. Due to the much lower process temperatures of this technology compared to soldering, temperature-sensitive high efficiency solar cells can be connected using adhesives in a gentle and material-saving process. In industrial production, the throughput is only slightly lower than with soldering. The reliability of the adhesive connection was confirmed in tests carried out in a climate chamber. »In the last few years, we were able to greatly expand our expertise in connecting solar cells using electrically conductive adhesives and test this process on the laboratory scale. With the stringer unit, we were then able to further optimize the lead-free interconnection technology on the industrial scale,« explains Dr. Achim Kraft, project manager and team head of Interconnection Technologies at Fraunhofer ISE. Axel Riethmüller, project manager and Chief Operating Officer of teamtechnik, is also pleased: »As

• Siemens Gamesa to supply 98 SWT-2.3-108 wind turbines • Blades and nacelles and hubs to come from Fort Madison, Iowa, and Hutchinson, Kansas, facilities, respectively Siemens Gamesa Renewable Energy (SGRE) announced today that the company will supply 98 SWT-2.3-108 wind turbines for an undisclosed project located in Kansas. The wind farm will span across over 40,000 acres of land and can supply enough energy for nearly 73,000 average U.S. homes. The blades for this project will come from Siemens Gamesa’s blade manufacturing facility in Fort Madison, Iowa, USA. The nacelles and hubs will be assembled at the company’s nearby nacelle and hub assembly facility in Hutchinson, Kansas, USA, making this a Kansas-made project for Kansas and contributing to investments back into the community. Deliveries for the project are expected to begin mid-2018 and completion of the project is slated for the end of 2018. Siemens Gamesa has installed over 5 GW, or more than 2,300 units, of the SWT-2.3-108 wind turbine in the U.S. In total, the company has provided turbines with an output capacity of more than 18 GW in the U.S., enough energy to power over five million average homes, and has a strong footprint consisting of manufacturing, service and offices.

The final turbines at the world’s largest offshore wind farm, off the coast of Cumbria, have now been installed. All 87 turbines are now installed at the Walney Extension wind farm, which is a shared-ownership project between Ørsted (50%) and two leading Danish pension funds PFA (25%) and PKA (25%). The 659MW wind farm has been installed in two phases utilising turbine technology from two leading manufacturers – MHI Vestas and Siemens Gamesa – with Seajack’s Scylla vessel installing all turbines. MHI Vestas Offshore Wind has installed 40 of its 8MW turbines, which have each been optimised to deliver a maximum output of 8.25MW. The first ever Siemens Gamesa 7MW turbines to be used in the field world-wide are also now installed. These 47 turbines complete the installation work on the project, which will become the world’s largest offshore wind farm once fully operational in the second half of 2018. Work is now continuing on the commissioning of the turbines and substations. When fully operational, Walney Extension will be capable of generating enough clean energy to meet the annual electricity demands of more than half a million UK homes. Speaking on behalf of Ørsted and partners PKA & PFA - Andrew Cotterell, Walney Extension Programme Director

Hamburg, 24 April 2018. With the signing of the power purchase agreement by public-sector utility Eskom, the contract for the installation of the South African wind farm “Roggeveld” has now also come into effect. This order for the Nordex Group entails 47 AW125/3150 and AW125/3000 turbines with a combined capacity of around 147 megawatts and a high capacity factor of more than 47 percent. The contract comprises the delivery of the turbines including the towers, which are to be produced in South Africa, as well as service for at least 15 years. Local installation work near Laingsburg will be commencing in 2019, creating a good 700 jobs in the construction and operation of the wind farm. Through a broad based approach this job creation will benefit local communities empowering young South Africans to build their future in clean energy. Moreover, the farm will improve the country’s carbon footprint as it will reduce around 24,000 tons of carbon dioxide emissions from the production of electricity each year. Building Energy, the customer and owner of the wind farm, is committed to improving the world´s future by investing in clean power stations. With operations all around the globe, the independent power producer applied
