In a commentary about the utilities sector, Zacks advised transmission lovers that they're about to become obsolete:
The emergence of Microgrids for power generation could threaten the dominance of the age-old power distribution system in the U.S. Microgrids have evolved from simple power backup systems to small smart grids. The swift and cost effective installation of Micro grids could help distribute electricity among the masses. These rooftop solar systems meet the energy needs of the customers. In addition, the customers are allowed to sell excess power back to the utilities.
A report from American Society of Civil Engineers estimated that utilities need to spend $763 billion by 2040 to properly modernize and harden the existing grids against natural disasters. We believe that rather than going for a very costly maintenance, it will be economical to develop these Microgrids, which could lend support to the existing system.
A microgrid is defined as:
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macrogrid). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then function autonomously. Generation and loads in a microgrid are usually interconnected at low voltage. From the point of view of the grid operator, a connected microgrid can be controlled as if it were one entity.
Microgrid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the microgrid from a larger network would provide highly reliable electric power. Produced heat from generation sources such as microturbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
Just one more warning shot across the investor owned electric utility bow. Transmission is a dead end. Save yourself, utility friends! After all, if my favorite utilities die, who am I going to pick on in my spare time?
