Big Transmission never did and never will make sense. Let’s look at a half-dozen reasons why: 1) the laws of physics, 2) higher reliability risk, 3) stricter contingency limits, 4) lumpiness and investment risk, 5) rigidity of source and sink, and 6) better alternatives.

It is difficult to apportion the demise of PATH among reduced load growth, the Mt. Storm-Doubs alternative, new generation, and sophisticated statelevel opposition. However, it is fair to observe that reduced load growth had only postponed PATH in the past (three times). What was different in 2010 was the emergence of the Mt. Storm-Doubs  alternative, and the focus of a state regulator on that alternative.

But certainly when Big Transmission is dependent upon market conditions the lumpiness and risk factors are all the more daunting. Big Transmission somehow needs to bring together generation resources and market demand – to the exclusion of alternatives – to forge a level of commitment that will last for many years. That’s a prerequisite for financing. So the entities at each end need to perceive such a compelling business proposition that they will forego other alternatives and cast their fate with Big Transmission. That’s a tough sell.

FERC requires that utilities interconnect all new generation. So a new generator is assured of being able to interconnect its project to the utility serving the territory it is located in; the issue is solely how much money and time it will take for the interconnection. Given this legally assured ability to access the grid through the resident utility, market-based Big Transmission is effectively competing with that utility and thus must offer substantial value added.

Despite identification of areas in which transmission capacity is limited, a “not in my backyard” (or anyone else’s, in some cases) attitude toward new transmission line siting has resulted in cancellation or delay of some new transmission lines.

For example, in 2011, PJM cancelled the proposed Potomac Appalachian Transmission Highline (PATH) project, a 275-mile transmission line that would have run through West Virginia, Virginia, and Maryland to deliver electricity into Northern Virginia. Although the line was designed to improve reliability in eastern PJM, changing forecasts of electricity demand growth and intense opposition to siting the line led to the project’s cancellation.

Beginning in the late 1920s, electric utilities began to integrate their operations to improve reliability and reduce costs. Previously, utilities had operated as “islands,” meeting the demand for electricity solely from their own generating plants. To ensure reliable service, this meant building extra generating capacity to keep in reserve, in case unexpected problems caused their plants to shut down.[2] By integrating their operations, utilities could provide more reliable service without building as much backup generating capacity. In essence, if a generating plant at Utility A suffered a forced outage, one of Utility B’s generators would be available to ensure the lights stayed on. The concept is similar to diversifying a financial portfolio. Instead of investing everything into just one company’s stock, buying multiple stocks, bonds, and other investments reduces the risk of a sudden financial loss.

Virginia regulators have approved construction of Panda Power's proposed 750-MW Stonewall natural gas-fired plant to be located south of Leesburg.

The project was strategically sited in one of the fastest-growing counties in the US, Panda said. The region is home to the Dulles Technology Corridor, a national hub for data storage, defense and technology companies. Dominion, the utility serving the region, said recently that demand from the facilities is expected to reach 1,000 MW annually in 2017.

The project would reduce Virginia's reliance on imported power to fill the gap between in-state production and load growth, Panda said.

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 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.

Frederick County Commissioner Billy Shreve is asking Potomac Edison to donate some land for a park; specifically, the 150-acre Browning Farm, where the utility was planning to build a substation for the Potomac Appalachian Transmission Highline.

He called it a win-win for First Energy and county citizens.
