Dr Michael Weinhold - CTO of the Siemens Energy Management Division

Weinhold’s Power Lines: Brains and Brawn - The Electronics Revolution and the Energy System

What is power? In human interactions, the term often refers to physical strength, but we also speak of “the power of information” as a way of shaping and directing the course of events. Power is the ability to influence the world in both material and immaterial ways – through intelligence and muscles, through brains and brawn. The same is true for the way in which electronics has reshaped the energy system. It was the invention of the transistor and its first commercial usage in the 1950s that ...

Solar+Battery

Tesla, cheaper batteries for solar systems, and managing the demise of traditional utility business models

A few weeks ago, Tesla Chief Executive Elon Musk took to Twitter to issue a new product announcement tease: “Major new Tesla product line—not a car—will be unveiled at our Hawthorne Design Studio on Thursday at 8 pm, April 30.” Word on the street is that the new product will be Tesla’s entry into home energy storage, leveraging Tesla’s battery Gigafactory announced last year. This joint venture between Tesla and Panasonic, expected to be completed in Nevada in 2020, would become the world’s larg ...

SIESTORAGE - initial installation at Enel in Italy

Continuous Power Flow? Totally Integrated!

Walking from one end of Siemens’ 3,500-sqm exhibition area to the other at this year’s Hannover Messe one solution was prevalent across all areas, from Energy to Industry: Totally Integrated Power. It was a way to physically experience the comprehensive scope of Siemens’ end-to-end portfolio encompassing software and hardware products, systems and solutions for all voltage levels – from high-voltage in-feed, to low-voltage consumption, from grid access via industry application to home supply. Ba ...

Saving costs is an important factor in the wind energy business

Higher Cost Efficiency for Wind Energy

In an environmentally friendly generation mix, wind energy is now playing a major role the world over. A long way to come for a comparatively young technology. While developments to tap its full potential are still well under way, Siemens’ wind energy innovations showcased  at this year’s Hannover Messe have  one goal in common: To make the well-established renewable energy source more cost efficient. Siemens is aiming to reduce the costs of wind power. Different approaches will contribute to t ...

Digitalization is enhancing Sustainable Energy Production - ALICE is a self-optimization process that has been developed to teach wind turbines how to automatically and optimally adapt their operation to its local conditions

The Winds of Digital Change - How Digitalization is enhancing Sustainable Energy Generation

As in previous years, the vast majority of solutions being showcased at this year’s Hannover Messe are focused on industrial digitalization in line with that ubiquitous buzzword, Industrie 4.0. As a counterpoint to this prevailing wind, I’d like to use this post to take a look at how digitalization is also revolutionizing the way energy is generated – and more specifically, wind energy. Two innovations in particular have caught my eye this year at the Siemens booth in Hall 9, which show how digi ...

How Digitization Drives Smart Grid Innovation

At this year’s Hannover Messe Siemens is showcasing the opportunities of Industry 4.0 and digitization for the energy business. The first blog post in the Hannover Messe series explained how necessary gains along the wind energy value chain can only be achieved with intelligent, digital solutions – ranging from software for blade optimization via control systems for wind power plants to machine learning solutions for wind turbine self optimization. Next, I would like to introduce a further promi ...

underground ac transmission lines in Germany, direct buried

Lines in a Can yet again – this Time for Direct Current

DC CTL and HVDC might sound like alphabet soup, but actually they are technologies to transmit electricity over long distances. Brunsbüttel to Stuttgart – nearly 700 kilometers. Güstrow to Munich – almost 900. In future, ever more electrical power will need to make such journeys, from offshore wind farms in the Helgoland Bight to population centers in the depths of Germany. This will be critical to the Federal Republic’s aim of generating 80% of its power by 2050 from renewable energy. It also ...

Weinhold’s Power Lines: Giving Form to Ideas

Selective Laser Melting for the Energy Business What is selective laser melting (SLM)? This innovative manufacturing process often reminds me of the “beamer” device in the TV series Star Trek: Information, given form, is translated into matter. A laser beam is applied to metal powder particles and welds them into threedimensional structures, layer by layer. Guided by a CAD blueprint, the substance rapidly hardens into a complex part. Compared to the more established 3-D plastic printing process ...

Telecontrol and many more thrilling topics: Four days at Wasser International come to an end

Rolf Pillath, Petra Geiss and René Jacobs from Siemens' booth team (from left to right) were very pleased with the response at the booth. The Wasser Berlin International trade fair was a resounding success for Siemens with lots of interesting conversations, valuable user feedback, and a great atmosphere. Experts from around the globe gathered at this leading trade fair for the water industry from March 24 to 27. Telecontrol technology and process instrumentation attracted particularly strong in ...
