The electric power industry has undergone dramatic change in the last decade. The widespread liberalization of the electric power industry in many countries, and the general need for increased efficiency and reliability in network operation have introduced new roles and new participants to the industry. Efficient and reliable energy generation is available in smaller units that provide more flexibility in placement while fossil fuels are increasingly proving to be more costly both financially and environmentally. The growing reliance on renewable resources and the application of smart technologies are causing fundamental changes in production and consumption patterns. Transmission systems are being used in new ways as new technologies are being applied. In the midst of this evolution are a multitude of regulating bodies with agendas that often seem to conflict. In this complex and changing environment, sound advice from experienced experts is essential.
