ABB to acquire Newave to broaden offering in uninterruptible power supply

ABB announces all-cash public tender offer of CHF 56 per Newave share, representing a total equity value of approximately CHF 170 million, to be unconditionally recommended by Newave’s Committee of independent members of the Board of Directors
Offer price represents a premium of 36.0% to the volume-weighted average share price of the last 60 trading days and a premium of 22.4% to the closing price on December 9, 2011
The three major shareholders of Newave, representing in total 45% of the voting rights and share capital, have signed separate agreements to sell their shares under the same financial conditions as offered in the public tender offer
ABB plans to develop Newave to become a center of excellence for UPS systems
Zurich and Quartino, Dec. 12, 2011 – ABB (ABBN.VX), the leading power and automation technology group, and Newave Energy Holding SA (NWEN.S), a Switzerland based leader in uninterruptible power supply (UPS), have agreed that ABB will acquire Newave in an all-cash transaction valued at approximately CHF 170 million1. The deal will strengthen ABB’s position in the power control and quality market and provide Newave with significant growth opportunities outside its traditional markets in Europe.

1 Fully diluted equity value

Under the terms of the transaction agreement, ABB today announced a voluntary all-cash public tender offer of CHF 56 per Newave share to purchase all of Newave’s publicly held shares. The offer prospectus will be published on or around Dec. 15. The offer represents a premium of 36.0 percent to the volume-weighted average share price of the last 60 trading days and a 22.4 percent premium to Newave’s closing stock price on Dec. 9. The Committee of independent members of the Board of Directors of Newave will unconditionally recommend that Newave shareholders tender their shares in the offer.

Under separate share purchase agreements, ABB acquires not conditional upon the public tender offer being successful a 45 percent stake in Newave held by the three major shareholders – being the two founders Vllaznim Xhiha, current Chairman of the Board of Directors, and Filippo Marbach, current Member of the Board of Directors and Chief Operating Officer, as well as Rittal International Stiftung & Co. KG. The major shareholders will receive the same consideration per Newave share as offered by ABB to public shareholders in the public tender offer.

Newave, headquartered in Quartino, Switzerland, generated a net income of CHF 8.1 Million on sales of CHF 80.6 Million in 2010. The company was founded in 1993 and went public in 2007. Newave has established a strong market position in Europe as an innovative and successful manufacturer of UPS systems with a focus on the development and production of power protection technology, as well as on technical consultancy, maintenance and service packages. ABB plans to integrate Newave in its Discrete Automation and Motion division and develop Quartino to become a main location for ABB’s UPS systems. ABB will provide a fast, global exposure for Newave’s UPS systems and will ensure that Newave can increase the high innovation rate of its current product range.

“The combination of two strong, complementary companies will create significant value-driven growth based on innovation, high quality and technology leadership,’’ said Ulrich Spiesshofer, head of ABB’s Discrete Automation and Motion division. “The acquisition is fully in line with ABB’s strategy for power control and quality and with the goal of the division to build on its existing strength in power electronics. Newave provides us a best-in-class player in the fast-growing UPS market, while our global sales channels will significantly expand Newave’s geographic reach.”

“Combining our business with ABB will give Newave important strategic and operational advantages. As Chairman of the Board of Directors of Newave, I am convinced that ABB is the ideal partner for the continuous successful development of our company,” said Newave’s Vllaznim Xhiha. “Besides the immediate financial added value of the offer for the shareholders, we also expect considerable additional development potential for Newave’s business partners and its employees.”

The global UPS market offers interesting growth opportunities, mainly in the areas of datacenters, industry and infrastructure. ABB will expand into a $6 billion to $7 billion market and close a white spot in core datacenter electrification and industrial power quality. Newave is active in the medium- and high-power UPS range, which is the most attractive segment since it represents 50 percent of the overall UPS market with a yearly growth rate of 6 to 10 percent. ABB has a strong presence in industrial markets and already offers industrial UPS products. It recently acquired a majority share in the DC datacenter solution provider Validus. Combining ABB’s and Newave’s market presence and technological expertise will allow ABB to offer a complete range of UPS solutions to industrial, commercial and datacenter clients with a comprehensive alternating current (AC) and direct current (DC) solutions portfolio, reinforcing its strategic differentiation.

Taking into consideration a fairness opinion by Bank Sarasin & Cie AG, the Committee of independent members of the Board of Directors of Newave – consisting of Rudolf Kägi and Mauro Saladini – regards the offer by ABB as fair and appropriate. The Committee will recommend to the shareholders of Newave to accept the offer in its report to be issued in ABB’s offer prospectus.

The public tender offer and the closing of the share purchase agreements are subject to regulatory approvals and other customary conditions. The offer period is expected to start in early January 2012 and the transaction to close in the first half of 2012.

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 130.000 people.

ITER - nuclear fusion power plant prototype HD

Fusion Energy: Promises Unkept? Holtkamp Norbert




Fusion Energy: Promises Unkept?

Holtkamp Norbert
2 videos
Fusion power as the source of energy on Earth has been the dream of mankind ever since the principles were understood. ITER, the Latin word for “the way”, is the world’s largest Fusion device presently under construction in Cadarache, France. Supported by the People’s Republic of China, the European Atomic Energy Community, India, Japan, the Republic of Korea, the Russian Federation, and the United States of America, an international organization was founded after the signature of the Joint ITER Agreement in October of 2006. The goal is to build a Fusion reactor with a power amplification of 10, a total fusion power of 500 MW or more operating at extended burn times of 400-3000 seconds, with Deuterium and Tritium as its basic fuel. Following a short introduction into fusion science principles, the history of thermo nuclear fusion will be covered. Finally more recent construction projects around the world, their latest achievements and the path to ITER will be described. Technological and scientific challenges of ITER together with their foreseen solutions will be then presented in more detail

Mark Suppes, 'Fusioneer', Part1 Building a homemade nuclear reactor in NYC



Mark Suppes is an Amateur "fusioneer," who's building his own fusion reactor in a garage near his Brooklyn, N.Y., home.

For him, fusion research is more than just a hobby. It's his chance to change the world. Although he has a full-time job and works on it when he can, he believes his research can make a difference in people's lives.

He has no formal physics training and says he's self-educated, largely through Wikipedia. He became interested in the topic when he saw a Google Tech Talk called, "Should Google Go Nuclear," presented by renowned nuclear physicist Robert W. Bussard. Now he's been at it for about 10 years.

Estratégias e desafios de uma indústria para se tornar um Global Player



"Para ser um global player não basta ter vontade. É necessário ter uma estratégia empresarial baseada em quatro pontos: perfil da empresa, concorrência, mercado e governo."A afirmação de Christian Muller, vice-presidente da B. Grob do Brasil, em palestra proferida no II NEI International Industrial Conference & Show, aponta os primeiros passos para uma empresa brasileira cruzar as fronteiras.

Defina o seu perfil empresarial. Para o vice-presidente da B. Grob, antes de tudo, é preciso definir a sua própria identidade perante o mercado. A história, tradição e cultura empresarial devem ser claras para a organização (os colaboradores) e o mercado (os clientes). Quais produtos/serviços serão oferecidos ao mercado? Quais serão os segmentos de atuação? De que forma a empresa irá atuar? Qual será o nível de qualidade do produto? Quais serão os preços praticados? Quais serão os prazos de atendimento? As respostas para essas perguntas compõem a definição empresarial de uma organização. "Ótima qualidade e rápido atendimento já são fatos consumados na indústria. No planejamento, o empresário deve focar em estratégias de melhor preço, pois o custo de um produto define cada vez mais uma venda", segundo Müller.

Analise seus concorrentes. "A análise dos concorrentes indicará onde estão os principais desafios da empresa e quais são as organizações que realmente estão incomodando", diz o palestrante. Além disso, uma análise profunda aponta importantes estratégias empresariais da concorrência, e algumas delas podem ser adaptadas aos negócios da organização.

Aprenda com o seu mercado. Para Müller, as melhores oportunidades de negócios surgem quando a real necessidade do cliente é entendida. Para isso é preciso analisar o perfil empresarial do cliente e encontrar algumas respostas. "O segmento de atuação do meu cliente está em crescimento? Qual é o lucro anual do meu cliente? Meu cliente vem crescendo em seu mercado de atuação? Meu cliente exporta? Qual é a qualidade do produto, o preço praticado e o prazo oferecido pelo meu cliente?", questiona. Esses indicadores, além de mostrarem empresas com potencial aumento de demanda, identificam novas oportunidades nas plantas dos clientes.

Latin America’s Surging Three-Phase UPS Market Projected to Reach $330 Million by 2015

Date: 23 November 2011

Uninterruptible Power Supply (UPS) revenues grew 24% in 2010, with a spectacular 58% surge for three-phase UPS greater than 100 kVA, according to a recent study on the market from IMS Research. In 2010, high power three-phase UPS, which are typically associated with data centers, picked up nearly 3 points share of Latin America’s UPS market thanks to the staggering growth in Brazil and Mexico. Latin America’s three-phase growth is forecast to continue with the help of government and infrastructure investments particularly in Brazil and Mexico.

Much of Latin America’s growth in 2010 can be attributed to the expanding IT market. The three-phase segment is forecast to continue seeing substantial gains as capital spending is going towards data center projects across all industries. Furthermore, single-phase UPS growth is slowing as compared to three-phase UPS growth since voltage regulators and laptop computers, which eliminate the need for an UPS, are becoming more widely used in Latin America.

“Brazil presents the best opportunity for three-phase UPS growth” says IMS Research Market Analyst Lori Lewis. “With an economically healthier middle class, more individuals are able to take advantage of modern day information technology and mobile computing devices resulting in exponentially growing computing and data storage needs. Three-phase UPS going into data centers will have to grow just as fast in order to keep up with all of this increased demand.”

Mexico is also experiencing a lot of activity, with large data center builds going into medium and large businesses, banking and infrastructure advances. Mexico, in fact, boasts significant advantages for foreign investors over Brazil due to fewer import taxes, fewer local competitors, fewer barriers to entry into the market and an overall more sustainable growth. Columbia has come under the radar as a promising investment with a well-educated population. The corruption, guerilla warfare and drug trafficking that scared investors away in the past has slowly subsided, allowing the country to develop properly.

With a good mix of established and fast-growing developing economies, Latin America is seen as secure and profitable for UPS suppliers looking to enter the market or enhance their presence in the region. Since Schneider Electric’s acquisition of local manufacturer Microsol, and Legrand’s recent acquisition of the large single-phase supplier SMS Technologia, the region continues to pick up global attention and stirs up the question of who will be next.

The Role of Power Electronics in the Future Smart Grid


ECE at the University of Utah presents:

"The Role of Power Electronics in the Future Smart Grid"
with:
Dr. Ram Adapa
EPRI (Electric Power Research Institute)

Abstract:
The future smart electric grid needs not only smart meters but also smart transmission and distribution technologies. Power electronics will play an important role in the future smart transmission by enhancing the transmission capacity, reliability, and security. Currently, transmission systems are becoming increasingly stressed because of growing demand and because of restrictions on building new lines. However, most high voltage transmission systems are operating below their thermal ratings due to such constraints as stability limits.

New Materials - Solar Capture & Storage - Professor Jeffrey Grossman - MIT Club of Northern California from Hank Magnuski on Vimeo.Hank Magnuski

Despite the enormous potential of solar power to generate electricity, solar photovoltaic (PV) technology is by far the least utilized renewable energy resource today. We need breakthrough advances in materials to capture and store solar energy so we can economically replace fossil fuels in the next few decades. Prof. Grossman will describe two radically new solar materials and the computational models that led to their discovery.
