The first edition of the ER, in December 2006, dealt with gas supply problems in Bolivia, Argentina and Brazil, which reduced the system's steady supply capacity by 16% and led to the "scare" of January 2008, when the risk Deficit ratio exceeded 30%. Since then, the ER has analyzed several progresses, for example auctions, some setbacks, and other "scares". To celebrate our anniversary, we decided to set up this book with the stories of the editorials, which always seek to join the reality of the power sector with some curiosities. Many thanks to our readers and we hope to continue deserving your interest and confidence in the now "pre-teen" ER. To see our book, download here or access Energy Report in Trial section.
