Generation of a €5 million pre-tax profit for FY 2016 Securing a 16-year op ration & maintenance contract Voltalia (Euronext Paris, ISIN code: FR0011995588), an international renewable energy player, announces the sale of its 100% stake in a French solar plant to a financial investor. Located in the French Provence-Alpes-Côtes d’Azur region, the solar plant, with a capacity of about 3 MW, has been developed, built and commissioned by Voltalia. With 9,360 photovoltaic panels, the plant provides the equivalent of the annual power consumption of about 1,400 households1. The disposal of this solar asset to an international financial investor, which is an existing client of Martifer Solar, reflects Voltalia’s ability to value its assets and its development skills while rolling-out its services activity for third-party clients. Indeed, the Group will remain in charge of the operation and maintenance of the plant, for which it has secured a 16-year long operation & maintenance contract. Beyond the operation & maintenance contract, this asset disposal will have a very positive impact on the second half-year results. It will generate a pre-tax income of at least 5 million euros.

ROMO Wind’s iSpin Guardian approach allows wind farm operators to monitor and actively manage the performance of every wind turbine in a wind farm at any time during its lifetime, independent of site complexity. The iSpin Guardian approach, which uses patented spinner anemometer technology, allows operators to compare the performance of individual turbines in a wind farm for the very first time. ECN (Energy research Centre of the Netherlands) has evaluated the approach. ECN is a globally-renowned renewable energy R&D institute and founding member of the industry-wide acknowledged MEASNET association. In its report, ECN confirms that the iSpin Guardian approach “based on the presented cases is well-suited to monitoring the relative performance of the turbines in a wind farm, which can be used to identify potential performance issues and which needs to be further validated.” In most cases today, performance measurements on wind farms are limited to one or two nominated turbines with free wind sectors, defined flat areas and using dedicated met masts – which does not allow accurate assessment of performance of all turbines in a wind farm. The systemic advantage of the iSpin Guardian’s spinner anemometer is that it measures the wind where it first hits the turbine –

Meyer Burger Technology Ltd (SIX Swiss Exchange: MBTN) announced today that it has initiated a company-wide structural programme. The objective of the programme is to extensively strengthen the company’s strategic technology units focussed on high-end photovoltaic user markets and to increase its flexibility in the often challenging high-end key markets. In addition, the global service business will be strengthened and individually expanded within local customer and application markets. As a result of the structural programme, the total operating cost base will further decline by about CHF 50 million. Meyer Burger has already executed numerous measures during the past five years, reduced its operating expenses, simplified its corporate structure and re-adjusted capacities due to the extremely challenging situation in the solar industry. The level of personnel and other operating expenses declined by over 36% from CHF 330 million in fiscal year 2011 to CHF 210 million in fiscal year 2015. In the first half of 2016, Meyer Burger achieved a profit at the EBITDA level for the first time since 2012. The positive EBITDA of CHF 6.2 million and the positive cash flow from operating activities of CHF 15.4 million for the first half-year 2016 confirm the direction the company has taken and

Open until 30 September at the Hamburg Messe fair site Hamburg, 28 September 2016 WindEnergy Hamburg is once again delivering proof of its role as a true global business platform for the wind industry. When the world's leading expo for wind energy opened this week, several international companies seized the opportunity to close or announce major business deals. Until Friday, roughly 1,400 exhibitors from 34 nations are showcasing product novelties and services for the onshore and offshore wind sector. Senvion and Trianel sign contract for wind turbines and services The manufacturer Senvion will supply the offshore wind turbines for the “Borkum II” Trianel wind farm. Both Senvion and Trianel signed the conditional contract for turbines and services for Trianel Windkraftwerk Borkum II GmbH & Co. KG (TWB II) at the WindEnergy Hamburg trade fair. The offshore wind farm, scheduled to be completed by autumn 2019, will comprise 32 Senvion 6.XM series wind turbines with a combined installed power generation capacity of 203 Megawatts (MW). Trianel-Windpark Borkum II will be built 45 kilometres to the north of the island of Borkum in the German North Sea.

• SWT-3.3-130LN for noise sensitive sites • Noise level at 104.9 decibels • Serial production in early 2017 High performance at low to medium wind speeds – that’s what the new Siemens low noise SWT-3.3-130LN wind turbine offers customers. The new model operates at a reduced rotor speed compared to the SWT-3.3-130, and includes aerodynamic addons to its rotor blades. Utilizing these add-ons, it can be operated at a noise level of 104.9 decibels. The new machine will be available in early 2017 in parallel with two additional onshore models launched by Siemens at the WindEnergy 2016 trade show in Hamburg. The fast air stream passing the tips of the rotor is primarily responsible for the characteristic noise of a wind turbine in operation. Aeroacoustic optimizations of the B63 blades allow silent operation of the new SWT--3.3-130LN turbine: In addition to vortex generators on the blade surface, trailing edges are equipped with a combination of serrations and combs, known as the new Siemens DinoTail Next Generation. Each combed teeth element creates fine vortices at the point where the fast air stream from above the blade profile meets the slower air stream flowing below. As a result, the aerodynamic noise from the trailing edge of the blade is reduced significantly. The result is high performance at low

•   Noise mitigation by biomimicry of owl wing’s trailing edge fringe •   Product launch “Next Generation DinoTail” •   Serial production to be started soon Silent operation of turbines is crucial for the success of many onshore wind projects. Siemens has therefore conducted extensive R&D over the last years to further reduce the noise of its wind turbines. An important breakthrough has now been achieved with the launch of a new generation of Siemens’ so-called DinoTail, an aerodynamic blade add-on. The trailing edge fringe of an owl’s wing provided the inspiration for this noise-reducing component. Owls are silent hunters. Flying without noise allows them to stealthily approach their prey – primarily smaller rodents. This is enabled by a particular structure of the owl’s wings: A serrated, fringed structure at the trailing edge, and small combs at the leading edge of the wings are believed to mitigate the noise of the air flow by generating fine vortices. This effect is now used by a new Siemens invention which optimizes the aeroacoustic performance of rotor blades. In addition to vortex generators on the blade surface, Siemens now equips trailing edges with a combination of serrations and combs. This combed teeth concept creates fine vortices at the point where the fast air
