Dear Readers,

In the Editorial message for the April issue, I wrote about a common interest in forecasting the market and industry trends, and pointed to grid investments of nearly USD750B in the first quarter of this year, which were all announced and covered in our breaking news, as one potential indicator of the future business. Since then we have published announcements on additional investments valued at more than USD1 trillion. While these announcements do not offer a foundation for accurate predictions, they inform our readers on the geographical areas of large investments and enable them to timely prepare for tenders. This is exactly what I hear, especially from the sales people, readers like about Transformers Magazine.

Our e-Bulletin is a very practical tool to keep updated with all developments on the global scene. This weekly publication will save you a lot of time, making all publicly accessible information available at a glance. Therefore, I would like to invite all our readers who haven’t subscribed to the e-Bulletin to do so as soon as possible, and encourage their colleagues, too. The registration is free and very quick to do – all that is necessary is to provide your name and email address at: http://www.transformers-magazine.com/e-bulletin

For readers looking to gain a deeper insight into the market, I recommend reading the market review article.
