The history of electricity is long and complex, with many inventors and scientists contributing to its development over hundreds of years. The path to the everyday use of electricity began to take shape in the 18th century, with Englishman Stephen Gray's demonstration of electric conduction and Benjamin Franklin's famous kite experiment in 1752. However, it wasn't until the late 19th century that the first electric companies emerged. The California Electric Company (now PG&E) in San Francisco in 1879 became the first utility to sell electricity from a central plant to multiple customers via transmission lines. Soon after, in 1880, the Grand Rapids Electric Light & Power Company began operating the world's first commercial central station hydroelectric power plant. The following year, Brush Electric Company set up a central station to supply a 2-mile length of Broadway with arc lighting. These early electric companies paved the way for the widespread use of electricity and the establishment of the power industry as we know it today.

The first electric company in the US was the California Electric Company, in 1879
The history of electricity is a long and fascinating one, dating back to 500 BC when Thales of Miletus discovered static electricity. However, the first electric company in the US was the California Electric Company, in 1879, which supplied power to multiple customers via transmission lines.
The California Electric Company (now PG&E) in San Francisco was a pioneer in the electricity sector. Using two direct current generators from Charles Brush's company, they powered multiple arc lamps for their customers. This marked the beginning of a utility selling electricity from a central plant to multiple customers, a significant development in the history of power transmission. The California Electric Company soon expanded its operations by opening a second plant with four additional generators.
The success of the California Electric Company spurred further innovation in the industry. In March 1880, William T. Powers and others established the Grand Rapids Electric Light & Power Company, which began operating the world's first commercial central station hydroelectric power plant in July of the same year. This plant, located in Grand Rapids, Michigan, utilised a water turbine from the Wolverine Chair and Furniture Company to light several storefronts.
The late 19th century saw rapid advancements in electricity generation and transmission. By 1882, Thomas Edison had developed the first large-scale investor-owned electric illumination "utility" in lower Manhattan, serving an area of one square mile. This was followed by the construction of the first electric transmission line in the US in 1889, spanning 13 miles between Oregon City and downtown Portland, Oregon.
The evolution of the electric generation industry continued with the development of different turbine technologies and the debate between direct current (DC) and alternating current (AC) systems. American inventor Charles Curtis offered an innovative turbine to the General Electric Co. (GE) in 1896, leading to the creation of a 500-kW Curtis turbine generator by 1901. The competition between Thomas Edison, who favoured DC, and George Westinghouse, an advocate for AC, culminated at the 1893 Chicago World's Fair, where Westinghouse secured the bid to power the event using Tesla's AC system.

Thomas Edison's Pearl Street Station, New York, was the first power station in 1882
On 4 September 1882, Thomas Edison publicly presented a complete system of commercial electric lighting and power at Pearl Street Station in lower Manhattan, New York. This was the world's first power station, marking the beginning of the electrical age and the modern electric utility industry.
Pearl Street Station featured reliable central power generation, safe and efficient distribution, and a successful end use—Edison's long-lasting incandescent light bulb—at a price that competed with gas lighting. Edison's system was the first to bring electric lighting directly into customers' homes and businesses, a niche not served by arc lighting systems.
Prior to the establishment of Pearl Street Station, Edison set up several experimental power installations, including a small lighting system at his Menlo Park lab in 1880 and lighting systems with other features at the Paris International Exposition and in London in 1881. These earlier installations allowed Edison's team to experiment with new ideas before creating the first permanent installation in New York.
One of the main challenges in constructing the Pearl Street plant was finding a way to generate enough power. Edison wanted to use a dynamo (now known as a generator), but none were powerful enough at the time. To solve this problem, Edison developed the "Jumbo" dynamo, a 27-ton machine that produced 100 kilowatts, enough to power 1200 lights. Six Jumbo dynamos were needed to light up the one square mile of New York City serviced by the Pearl Street plant.
Another significant obstacle was devising a way to track energy consumption so that customers could be charged for the exact amount of power they used. Although there had been instruments to detect and indicate the flow of a current since the early 1800s, there was no way to record that flow over time. A successful design for an electric meter was not available until the spring of 1882. Despite these challenges, the Pearl Street system worked well, and the offices of The New York Times were among the first to get the new system.

The first long-distance transmission of electricity was in 1884
The history of electric power generation and transmission is long and complex, with numerous technological milestones. The first long-distance transmission of electricity took place on June 3, 1889, when electrical energy flowed from the Station A hydroelectric generator at Willamette Falls to street lights in downtown Portland, Oregon, 14 miles away. This was a major innovation in energy technology, as it demonstrated the feasibility of transmitting power over long distances. Prior to this, power generation was largely local, and it was unclear if electricity could be transmitted effectively over long distances.
The Willamette Falls project utilised six copper lines to carry 4,000 watts of direct current to 55 street lights. This achievement built on earlier innovations in electric conduction and generation, such as Englishman Stephen Gray's demonstration of electric conduction, which led to the 1740 invention of glass friction generators in Leyden, Germany.
The 1884 International Exhibition of Turin, Italy, featured an early demonstration of long-distance transmission. A 21-mile, 2-kV, 130-Hz Siemens & Halske alternator powered incandescent lamps. This system proved the concept of long-distance AC power transmission. However, the Willamette Falls transmission in 1889 was the first to send power over a truly long distance, heralding a new era in energy technology and centralisation of power generation.
The early days of electric power usage faced several obstacles, including the need for specialised generators and separate lines for devices requiring different voltages. The transmission of electricity over long distances was known to be possible with higher voltages, but early electricity was primarily direct current, which could not easily be adjusted for long-distance transmission. The success of the Willamette Falls project and the development of alternating-current transmission in 1895 helped shift power generation to larger, centralised plants and enabled the transmission of power over increasingly long distances.

The first commercial central station hydro-electric power plant was in 1880
The history of electricity generation is long and complex, with many inventors and companies contributing to its development over the years. One of the key milestones in this history was the establishment of the first commercial central station hydro-electric power plant in 1880.
The Grand Rapids Electric Light & Power Company began operating the world's first commercial central station hydro-electric power plant on July 24, 1880. The plant, located in Grand Rapids, Michigan, utilised a water turbine from the Wolverine Chair and Furniture Company to generate electricity. This early power plant illuminated several storefronts in Grand Rapids with a 16-light Brush electric dynamo.
The development of the Grand Rapids plant was not an isolated event, but part of a broader trend in the late 19th century towards the commercialisation and distribution of electricity. In 1879, the California Electric Company (now PG&E) in San Francisco utilised Charles Brush's direct current generators to supply multiple customers with power for their arc lamps. This marked the first instance of a utility selling electricity from a central plant to multiple customers via transmission lines.
Around the same time, Thomas Edison was also making significant strides in the field of electricity generation. By 1880, Edison had already demonstrated a system for generating electricity with low-resistance generators that powered low-resistance incandescent bulbs. In 1882, just two years after the Grand Rapids plant began operating, Edison established his first commercial power station in New York City, known as the Pearl Street Station. This station initially relied on steam power, but soon began exploring alternative sources, including water.
The success of these early power plants, including the Grand Rapids Electric Light & Power Company, laid the foundation for the widespread adoption and distribution of electricity. They sparked a wave of innovation and commercialisation, with numerous companies entering the market and new technologies being developed to meet the growing demand for electrical power.

The first wind-powered turbine connected to the grid was in 1941
The history of electric power generation is long and complex, with numerous technological milestones. The first electric company was the California Electric Company (now PG&E) in San Francisco in 1879. It used two direct current generators from Charles Brush's company to supply multiple customers with power for their arc lamps.
In 1883, the Austrian Josef Friedländer installed the first electricity-generating wind turbine at the Vienna International Electrical Exhibition. This was a Halladay windmill for driving a dynamo, supplied by the U.S. Wind Engine & Pump Co. of Batavia, Illinois.
While wind power has been used for thousands of years, the first wind-powered turbine connected to the grid was in 1941. This was a 1.25-MW turbine on a hill in Castleton, Vermont, called Grandpa's Knob. This was a significant milestone in the evolution of wind power, which had been gaining popularity alongside hydropower in the late 19th and early 20th centuries. The oil crisis of the 1970s renewed interest in wind power, and in 1978, President Jimmy Carter signed the Public Utility Regulatory Policies Act, which required companies to purchase a certain amount of electricity from renewable sources, including wind. The first utility-scale wind farms began appearing in California in the 1980s, and Europe installed its first offshore wind farm in Denmark in 1991.
Wind turbines convert the kinetic energy of wind into electrical energy. They can be stand-alone or clustered together in wind farms, which are typically located in windy areas to maximise energy production. Wind turbines vary in size, with smaller turbines used for applications such as battery charging and powering remote devices, while larger turbines can contribute to a domestic power supply.
