Utility and transportation decarbonization is rapidly gaining traction as the economic advantages of renewable energy, technology acceleration, and a social mandate for clean energy propel us into a much different world than we have experienced over the previous century. Electric car manufacturer Tesla recently became the most valuable car manufacturer by market capitalization over long-standing companies like Toyota, GM, Ford, and Volkswagen. The electric power industry is also changing. And, the pattern in which decarbonization change is occurring is the same for both transmission and distribution companies. Understanding this pattern can help utilities be very strategic and pragmatic, even allowing them to choose whether to play defense or offense as renewable energy and other Distributed Energy Resources (DER) enter their networks.
