The increased focus on renewable energy, the implementation of the EU's Third Energy Package, and other recent European energy initiatives mark an unprecedented stepping stone in the strengthening and further integration of the European Energy Market. The legal framework of the European energy sector is not left unaffected by this evolving European Energy Market: it is undergoing fundamental and continuous changes. Key players - such as the European Commission, the Agency for the Cooperation of Energy Regulators (ACER) and the national transmission system operators, market players, generators, etc. - are all heavily involved in this transformation. The impacts of the remodeling of the electricity sector's legal environment are being felt at all levels and must be reckoned with in daily business transactions. Companies directly active in the electricity sector are not the only ones to feel the consequences; the reach of this makeover extends all the way to citizens' lives and companies' operations. In light of such core changes, a significant increase in volume and rapid evolution, navigating the EU electricity legislation maze has become a real challenge. This book provides the solution to this hurdle: a single publication combining the most relevant and up-to-date legislation. It is an indispensable work tool for every expert and practitioner regularly confronted with the daily challenges of the electricity sector. (Series: EU GEO Laws - Vol. 1)
