Power generation systems – whether in the renewable or conventional energy sectors – provide our daily global electricity needs. In the 1880s, electric lighting systems were some of the first applications of electricity to modern American life.
One of the biggest differences between the small electricity grid at Pearl Street and the electricity we use today is that Edison used direct current (DC), while today’s grids use alternating current (AC). In fact, Edison’s Pearl Street Station had no “transmission” component, as we use that term today. A Serbian-American inventor named Nikola Tesla is the most famous of the electrical engineers who revolutionized the way we transmit electricity. In 1893, Westinghouse and Tesla saw an opportunity to prove that AC was the system of the future to an audience of millions at the Chicago World’s Fair. Later in 1893, the Niagara Falls Power Company awarded Westinghouse a contract to harness the power of Niagara Falls and to deliver it to Buffalo, New York—22 miles away—using his new AC technology. Westinghouse’s new transformers allowed him to send power efficiently first to Buffalo, New York, and ultimately all the way to New York City as more generators came online at the station. Samuel Insull, a pioneering young businessman who had worked as Edison’s assistant and then business partner, had a breathtaking vision for electricity in the era of long-distance transmission. Pushing the physical and economic limits of the high-voltage AC transmission system, Insull revolutionized the electricity industry by building larger generators and by transmitting power over longer distances. Insull’s focus on spreading electricity to new customers made him one of the great “democratizers” in American history. The characteristic feature of modern electricity transmission is the high-voltage power lines that stretch across the entire continent. The grid is actively monitored 24 hours a day by various grid operators, also called balancing authorities.
Although transmission represents a small portion of the overall cost of electricity, building and expanding the electricity transmission infrastructure is expensive. Because of these high capital and administrative costs, the transmission system exhibits what economists call “economies of scale.” That is, as the system gets larger, the cost per unit of electricity goes down, and it becomes increasingly difficult to build a competing system that is economical. By pricing transmission congestion, RTOs drive transmission investments to the parts of the grid that are constrained. The future of the electricity transmission grid is generally bright, with investment now hitting its highest levels in decades. This time on the Energy Futures blog we have Clara Heuberger who works in both the Centre for Environmental Policy and the Centre for Process Systems Engineering. I am a PhD student at Imperial College London  investigating low-carbon technologies, in particular how we can burn fuels without producing excessive carbon dioxide. My research is focussed on low-carbon energy technologies, particularly Carbon Capture and Storage (CCS), as it could be a solution to the problems created by the world’s current reliance on fossil fuels. Currently I am working on a project for the International Energy Agency (IEA) with colleagues in Imperial College’s Business School.


The IEA project is looking to answer questions about the market for flexible low carbon electricity and the political support mechanisms for such systems. These systems require optimized, robust, reliable and cost-effective engineering and innovative solutions over their complete product life-cycle, including the need for conventional power to meet increasingly stringent emissions legislation and alternative fuel supply challenges. After electricity is generated at a power plant, it needs to be transmitted on high-voltage power lines before it can be distributed to our homes and businesses. In those early systems—like Thomas Edison’s Pearl Street Station in Manhattan, which energized America’s first power grid—electric power stations served customers in a small network that covered only a few city blocks.
Early power grids were small by today’s standards, in part because of the physics of direct current networks. Copper wires buried underground carried power only a short distance from the station to the electric lamps of Edison’s customers. Working with entrepreneur George Westinghouse, Tesla and the early AC engineers made long-distance electricity transmission possible.[3] Instead of generating DC power, their solution was to generate a completely different kind of electric power—AC—and to use new transformers to increase and decrease the voltage.
With the help of Tesla and other electricity innovators, Westinghouse Electric Corporation built a hydroelectric power station at Niagara that would again test AC technology. Year after year, his Chicago-based company brought the cost of electricity down while significantly increasing the number of people with access to it. By the end of the 1920s, his companies were serving more than four million customers in 32 states.[11] He would go on to network his transmission facilities with those of other companies, creating an interconnected web of electricity that powered cities and farms alike and laid the foundation for today’s power grid. These balancing authorities work to keep the electric grid in balance at all times by making sure that the supply of electricity meets demand in real time. We don’t experience the “tea time pick-up” shown in the video above, but demand on grids in the U.S. As it leaves the power station, electric power is typically stepped up to anywhere from 69,000 to 765,000 volts.[19] Compare this to the electricity in your home, which comes in around 120 to 240 volts. The transmission system’s size and complexity are significant barriers to entry for new companies, owing to the massive initial capital investment needed to transmit power.
As a result, economists consider electricity transmission a “natural monopoly,” where only one utility will supply a given area with just one grid. They also make wholesale markets more transparent and allow the conditions on the grid to be visualized with the help of a price contour map. The latest piece of research I am doing revolves around these very questions and requires inputs from a diverse range of people and disciplines.
My research looks at multiple levels of the problem, from the chemical reactions right up to the national energy system. CCS is a wide range of technologies that aim to reduce harmful greenhouse gases out of power plant emissions so that we can reduce their environmental impact. The study is looking at the future use and impact of power plants equipped with CCS technology. Ultimately my work is combining engineering and economics to identify an optimal configuration for CCS systems as well as their value to the UK’s energy economy.


This page focuses on the middle stage—electricity transmission from power plants to local distribution grids.
DC networks had to operate at low voltages in order to be safe, the downside being that transmitting low-voltage power is inefficient. Pearl Street was a huge leap forward—some call it “the beginning of modernity”—but grids powered by direct current only worked in densely populated areas like lower Manhattan.[2] It was nearly impossible for anyone to implement on a wider scale. That was the beauty of the AC breakthrough: it meant that electricity could be transformed from low to high voltage and back, which increased the efficiency of transmission and allowed Westinghouse’s early transmission lines to span longer distances.
These were important engineering milestones, but what visitors adored was the sheer beauty of seeing so many lights ignited in one place, at one time.” The Devil in the White City, by Erik Larson[5]. The team of engineers at Westinghouse’s company had to build custom transformers to increase the voltage of the power generated at Niagara from 2,200 to 11,000 volts before placing it on transmission lines. By 1911, Insull’s AC grids spanned entire states.[10] At the same time, Insull was influential in creating the regulatory framework for electric utilities, which is still generally intact.
Currently, no technology exists that can store electricity cost-effectively on a large scale.[16] For that reason, balancing authorities rely on generators to respond to changes in demand at a moment’s notice.
The unique economic structure of transmission is one of the main justifications for government regulation in this industry.
I am also interested in how to achieve carbon-negative energy production whereby the net effect of generating electricity would actually reduce the carbon dioxide in the atmosphere. CCS power plants will have to meet flexibility requirements to balance the increasing amount of intermittent sources from renewable energy production.
In many ways, electricity transmission is the unsung hero of our modern, electrified economy. In the video below, the BBC explores the challenge of keeping the British National Grid grid in balance in the face of demand fluctuations.
Below, we see a typical “load curve,” which is an illustration of the level of demand at different times of day.
Also called locational marginal prices or LMPs, they reflect the marginal cost of electricity generation plus a transmission premium.
We will try to analyse the value added by available CCS technologies and understand their position within the UK’s energy market.
It is the task of grid operators to increase and decrease supply to follow this curve, second by second. Considerations go from the economic aspects, like how much people are willing to pay for a reliable electricity supply, to the technological, such as the details of the different CCS technologies used. Yet in the future, that might not be the case, as new laws and regulations threaten to make the grid unstable.
