Zurich, Switzerland, August 30, 2017 – ABB’s battery based storage system to optimize use of renewable energy while enhancing grid stability and power quality ABB has won an order from DONG Energy, the leading Denmark based sustainable energy group, to deliver a two megawatt (MW) Battery Energy Storage System (BESS) to support the integration and transmission of power from the Burbo Bank offshore windfarm near Liverpool, UK. The 90 MW Burbo Bank offshore wind farm has been in operation since 2007 and is capable of supplying electricity for up to 80,000 UK homes. This will be the first time an offshore windfarm integrates such a storage system to stabilize the frequency of the grid in UK. The UK’s National Grid operates a frequency level of 50 Hertz (Hz) to ensure grid stability and quality of power supplies. Grid frequency is dependent on the balance between power supply and load demand. Integration of large amounts of variable wind energy increases complexity from a supply perspective and can result in frequency variations that can affect grid supply and impact consumers. ABB’s BESS solution will help stabilize grid frequency and support the windfarm to supply reliable power. “We are delighted to implement this innovative solution which

N149/4.0-4.5 to be presented at Husum Wind Flexible turbine concept for individual site optimisation Currently the highest yielding and quietest onshore turbine for light-wind regions in the class of 4.0 – 4.5 MW Hamburg, Husum, 1 September 2017. At the Husum Wind wind fair, taking place from 12 - 15 September 2017, the Nordex Group will present the latest development stage of its successful Delta platform: the Delta4000 series. The N149/4.0-4.5 turbine, which has been designed specifically for light-wind regions, has a 30 percent increase in rotor sweep and a variable power output of 4.0 to 4.5 MW. The N149/4.0-4.5 is currently the highest yielding onshore turbine for light-wind regions in the class of 4 – 4.5 MW. What makes the N149/4.0-4.5 special is its potential to meet a wide range of site-specific requirements with one hardware version. As the maximum output of the turbine varies between 4.0 and 4.5 MW, it is ideal for adapting to the grid operator's individual requirements, local wind conditions and noise restraints. This also means that it’s possible to optimise the overall yield of a wind farm by means of the different maximum output of individual turbines, thus always exploiting the full potential of

Neuilly-sur-Seine, France, August 31, 2017, Leading international classification society Bureau Veritas has issued new rules for the Classification of Offshore Service Vessels and Tugs, including new class notations for pipelay vessels, accommodation units, offshore construction vessels and offshore support vessels. Gijsbert de Jong, Bureau Veritas Marine Marketing and Sales Director, said: “With this new publication Bureau Veritas provides the industry with a clear framework for the classification of offshore service vessels and tugs based on an end-user friendly system of class notations reflecting the terminology used by the industry. This document is the culmination of a development plan aimed at addressing the specific requirements of key offshore operations in our rules.” The new rules set out requirements for the classification of a wide range of vessels performing construction, installation, maintenance and other support activities at sea. These requirements cover towing, anchor handling, supply, fire-fighting, oil recovery, diving support, lifting, standby and rescue, accommodation, pipe laying, cable laying and semi-submersible heavy transport vessels. New and updated class notations and service features have also been included for: Wind turbine installation vessels Self-elevating units - covering the legs and elevating systems fitted on liftboats MOUs (Mobile Offshore Units) Code compliant accommodation SP[PoB]-capable (Special Purpose / number

Munich, 31 August 2017: As a leading provider in the renewable energy sector, BayWa r.e. will also have a booth at the major German wind trade fair Husum Wind 2017. From the 12 - 15 September, the company will present its wide-ranging service portfolio at booth 2D10, in Hall 2. Renewing wind energy together With its WindGuide 20+ product, the company is responding to the fact that a large number of wind farms in Germany will cease to qualify for the feed-on tariff over the next few years. BayWa r.e. helps operators to decide what the future of their wind farm will be and provides support in the creation of tailored, economic and logical concepts. Solutions are presented to operators in an initial assessment – from optimised further operation, including energy marketing, to location-specific re-powering to the removal and sale of used installations. As a full service provider, BayWa r.e. is able to deliver all services from a single source. In response to the amended framework conditions and the introduction of wind tendering, the company will also present partnership models tailored according to various requirements for public utilities companies, project developers and public involvement energy companies. New ideas for optimised operation Even in the area

ELA Container Offshore GmbH will again be participating at the Offshore Europe 2017 in Aberdeen. The exhibition will take place from 5th – 8th of September 2017 in Aberdeen, Scotland. In Hall 1 at booth #H21, ELA Offshore will be exhibiting a two story Offshore Accommodation Complex to demonstrate one of the many configuration possibilities of their high quality containers. One highlight of the exhibition – next to the roof-top terrace- will be their new type of Accommodation Container with interior corridor: the ELA Offshore Accommodation Container, Type: PREMIUM. ‘’The key element that differentiates our new type of Accommodation Container from other containers on the market, is their interior corridor. By including interior corridors in the design of the container, we eliminate the need for external gangways, which saves our customers space and money. Besides, the internal corridor facilitates crew transfers between modules and reduces safety hazards and crew exposure to weather conditions’’, states Hans Gatzemeier, Managing Director of ELA Container Offshore GmbH. In addition to interior corridors, the containers have 6,5 m² of living space per person with a single cabin and own bathroom, this all according to German quality standards and international rules and regulations. Visitors can expect an
