Rural electrification
Rural electrification is the process of bringing electrical power to rural and remote areas. Rural communities are suffering from colossal market failures as the national grids fall short of their demand for electricity. As of 2019, 770 million people live without access to electricity – 10.2% of the global population. Electrification typically begins in cities and towns and gradually extends to rural areas, however, this process often runs into obstacles in developing nations. Expanding the national grid is expensive and countries consistently lack the capital to grow their current infrastructure. Additionally, amortizing capital costs to reduce the unit cost of each hook-up is harder to do in lightly populated areas. If countries are able to overcome these obstacles and reach nationwide electrification, rural communities will be able to reap considerable amounts of economic and social development.
Social and economic benefits
Education
Access to electricity facilitates sustainable economic and social growth. First, through an increase in educational achievement. Students who could only study by sunlight were now able to study by the light of LEDs early in the morning or late into the night. In Kenya for example, interviews with school teachers revealed that access to light has allowed for extra hours of teaching earlier and later in the day to cover material not adequately reviewed during normal hours. Additionally, schools with access to electricity are able to recruit higher quality teachers and have seen improvements on test scores and graduation rates, raising the human capital entering the labor force in the future.Productivity and efficiency
In addition to improved education, rural electrification also allows for greater efficiency and productivity. Businesses will be able to keep their doors open for longer and generate additional revenues. Farmers will have access to streamlined modern techniques such as irrigation, crop processing, and food preservation. In 2014, rural communities in India gained more than US$21 million from increased economic activity driven by recent additions of electricity.Job creation
When expanding the electrical grid, there is a demand for thousands of jobs ranging from business development to construction. Projects to spread electricity create a wealth of job opportunities and help to alleviate poverty. For example, India set a target of 175GW of clean energy to be installed by 2022 to increase electrification throughout the country. An estimated 300,000 jobs will need to be created in order to reach these lofty goals.Healthcare improvements
The availability of electricity can drastically increase the quality of healthcare provided. Improved lighting increases the time patients can come and get treatment. Refrigerators can be used to conserve incredibly valuable vaccines and blood. Sterilization measures will be improved and the implementation of high tech machines such as x-rays or ultrasound scanners can provide doctors and nurses the tools they need to perform. In Diara Rhashalpool, a cluster of villages on the river Ganges, 140 households are without power. The locals are forced to travel 2–3 hours across the river for treatment or access to vaccines. With access to electricity, treatment would be far more accessible to the local population.Additional benefits
- Reduce isolation and marginalization through telephone lines and Television
- Improve safety with the implementation of street lighting, lit road signs.
- Reduce expenses on expensive fossil fuel lamps i.e. kerosene
Technology
Renewable off-grid enterprises have emerged in many areas to meet the demand for electricity in rural communities. Due to their geographical location and relatively low aggregate demand, expanding the nationwide grid to rural areas is expensive and challenging. Renewable energy based mini grids are less dependent on larger-scale infrastructure and can be implemented faster and cheaper. Where an electric power distribution grid can be set up single wire earth return is often used. The following technologies are used extensively:- Photovoltaics
- Wind mechanical water pumps
- Small wind electric
- Diesel solar hybrid power systems: especially for telecommunications worldwide. Fully commercial and the preferred option for remote telecommunications, commercially evolving for village power.
- Bioenergy
- Micro hydro is very widely implemented in Nepal, Vietnam, and China.
- Hybrid power is also widely used where a number of different technologies are combined to provide a single power source.
Challenges
Researchers pointed out that while many supportive policies have been put in place, cost for providing electricity to remote villages remains high. Furthermore, both energy resources and demand in these areas can be very volatile, making it difficult to plan appropriately. Another issue is that village location was determined historically based on soil, water, storage, etc., and might not be optimal for renewable energy generation.To mitigate these issues, the Networked Rural Electrification Model has been proposed. In this model, villages in a selected area are linked up via an optimal network, which in turn connects to a few centralized generation facilities located at spots with better renewable energy resources. As such, each village is partially supplied by small local facility, and partially by the centralized facilities. This improves energy resources utilization as well as overall system flexibility and reliability. Viability of this model depends on the cost of building the optimal network. Based on multiplier-accelerated A* algorithm, the researchers have devised an effective method for evaluating all possible connections under complex geographical structure and hence practically optimize network design. Economic justification follows.
National initiatives by continent
Africa
EthiopiaEthiopia rural electrification started in 1998 then followed by the Millennium Development Goal 1998-2002 Universal Electric Access Program started and the program planned to electrify 6000 villages in 5 years. After lessons were taken from that the Growth and transformation plan were launched. The program is one of the successfully accomplished in increasing the rural access rate and transforming the rural community, creating jobs, local contractors and cooperatives. The program was financed by supporting funds, loans and government.
Kenya
Karanja describes the role that a coordinated approach to rural electrification can play in Kenya and the challenges that arise. One solution is the combine numerical electricity system modeling with geographical information to explore various mixes of grid extension, mini-grids, and standalone systems.A 2024 study evaluating solar mini-grids in Kenya found significant improvements in household income, safety, and productivity. The median income in electrified Kenyan communities increased fourfold, indicating strong social and economic impacts of rural solar deployment.
Senegal
Senegal's electricity sector was reformed in 1998. Since then the country has implemented several electrification initiatives:- A national Senegalese Rural Electrification Action Plan, designed to increase private sector participation in rural electrification ;Covenants and an Emergency Programme, both led and funded largely by the Government of Senegal;Individual projects led by NGOs and private companies.
Americas
Brazil
In 1981, 74.9% of Brazilian households were served by electric power, according to the IBGE's National Sample Survey of Households. In 2000, the Federal government of Brazil, under the Fernando Henrique Cardoso administration, launched the Luz no Campo program to expand the distribution of electricity in Brazilian domiciles, with a focus on rural households. From 2003 on, the program was reinforced and renamed Luz para Todos by the Lula administration. The results were that, according to the PNAD, by 1996, 79.9% of all households had access to an electric power supply and that proportion rose to 90.8% in 2002 and 98.9% in 2009.Haiti
Haiti remains the least electrified country in the Western Hemisphere, but several ambitious efforts have launched to address rural electrification in the country. Some have pointed out that because so much of rural Haiti currently lacks utility infrastructure, Haiti is well-positioned to leapfrog into modern, modular energy systems like microgrids powered by renewable energy. The Haitian Government's energy regulator, along with the Energy Cell of the Ministry of Public Works and international partners are working to remove barriers and increase investment in renewable energy for both new, isolated mini-grids and regional grids.Using 2020 data, the Inter-American Development Bank estimated that 45% of the Haitian population had access to electricity. But frequent fuel shortages and other service disruptions mean that the population's real access to reliable electricity service is much lower. For example, in 2021 and 2022 even the nation's most important hospitals were curtailing their services due to lack of fuel to power their own generators for on-site electricity.
Jamaica
The was incorporated in 1975 with the specific mandate to expand the reach of electricity supply to rural areas, where the provision of such services would not be economically viable for commercial providers of electricity. The REP extends the national grid through the construction of electrical distribution pole lines to un-electrified areas and provides house wiring assistance through a loan programme to householders.In June 2012 that, approximately 16,000 homes in remote parts of the island which do not have electricity are to be supplied with solar or wind electricity through the Rural Electrification Programme. At a USAID-funded Analysis and Investigation for Low Emission project symposium, held at the Jamaica Pegasus Hotel, on Tuesday, July 9, 2013, Energy Minister Phillip Paulwell that the REP has also been mandated to complete its target of providing electricity to 100 per cent of rural areas. "Those three per cent that now remain are in areas that are so far from the grid, it is too expensive, and we are going to be deploying photovoltaic systems in these areas," he explained. In March 2015 he told a newspaper that, by 2017, "we should no longer have REP in the way we do now", adding that if the Government finds it too challenging to run power lines into communities, it will use solar."

United States
In 1892, Guy Beardslee, the original owner of Beardslee Castle, was paid $40,000 to provide hydroelectric power to East Creek in New York.Despite widespread electricity in cities, by the 1920s electricity was not delivered by power companies to rural areas because of the general belief that the infrastructure costs would not be recouped. In sparsely-populated farmland, there were far fewer houses per mile of installed electric lines.
A Minnesota state committee was organized to carry out a study of the costs and benefits of rural electrification. The University of Minnesota Department of Biosystems and Agricultural Engineering, working jointly with Northern States Power Company, conducted an experiment, providing electricity to nine farms in the Red Wing area. Electricity was first delivered on December 24, 1923. The "Red Wing Project" was successful – the power company and the university concluded that rural electrification was economically feasible. The results of the report were influential in the National government's decision to support rural electrification.
Before 1936, a small but growing number of farms installed small wind-electric plants. These generally used a 40V DC generator to charge batteries in the barn or the basement of the farmhouse. This was enough to provide lighting, washing machines and some limited well-pumping or refrigeration. Wind-electric plants were used mostly on the Great Plains, which have usable winds on most days.
In 1933, the Tennessee Valley Authority was created, in part, to provide rural electrification in the Tennessee Valley and surrounding areas. TVA created the generation and wholesale transmission capabilities that enabled rural distribution systems through electric cooperatives.
Of the 6.3 million farms in the United States in January 1925, only 205,000 were receiving centralized electric services.
The Rural Electrification Administration was created by executive order as an independent federal bureau in 1935, authorized by the United States Congress in the 1936 Rural Electrification Act, and later in 1939, reorganized as a division of the U.S. Dept. of Agriculture. It was charged with administering loan programs for electrification and telephone service in rural areas. Between 1935 and 1939 – or the first 4½ years after REA's establishment, the number of farms using electric services more than doubled.
The REA undertook to provide farms with inexpensive electric lighting and power. To implement those goals the administration made long-term, self-liquidating loans to state and local governments, to farmers' cooperatives, and to nonprofit organizations; no loans were made directly to consumers. In 1949 the REA was authorized to make loans for telephone improvements; in 1988, REA was permitted to give interest-free loans for job creation and rural electric systems. By the early 1970s about 98% of all farms in the United States had electric service, a demonstration of REA's success. In 1994 the administration was reorganized into the Rural Utilities Service by the Federal Crop Insurance Reform Act of 1994 and the Department of Agriculture Reorganization Act of 1994.
In September 2018, the U.S. Department of Agriculture said it would spend $398.5 million in infrastructure projects, by way of loans, that seek to improve electricity service in rural areas. The program is called the Electric Infrastructure Loan Program. Of the $398.5 million, $43 million will be to invest in smart grid technology. According to Smart Cities Dive, "The largest loan will send $68.5 million to back a solar farm run by NextEra Energy Resources in Arkansas, which could meet the needs of 21,000 homes." The loans will go to projects in 13 states: Arkansas, Colorado, Indiana, Iowa, Minnesota, Missouri, New Mexico, North Carolina, Ohio, Oklahoma, South Carolina, Texas and Virginia.
Asia
China
By the 1970s, household electrification had become commonplace in urban centres across China, however, it remained rare in the countryside and in smaller, outlying centres.Even in the early 1990s rural areas of China still suffered from extreme energy poverty; more than 40 percent of rural Chinese had no access to power or electric lighting at all, depending instead on kerosene lamps for lighting. In the early 1990s the average use of power in the countryside amounted to the equivalent of a 60W light bulb switched on for less than 30 minutes a day.
Deng Xiaoping, who became China's leader in 1978, initiated a rural electrification drive as part of a broader modernization effort, aimed at bridging the divide that had opened between the city and the country. This initiative steadily gained traction over the next two decades, and by 2000 electricity had become virtually universal across regional China, with only the most remote areas still lacking access.
China launched the China Township Electrification Program in 2001 to provide renewable electricity to 1,000 townships, one of the largest of such programs in the world. This was followed by the China Village Electrification Program, also using renewable energy, aimed at the electrification of a further 3.5 million households in 10,000 villages by 2010, to be followed by full rural electrification by 2015.
In December 2015, China brought the last 39,800 Chinese onto the national electric grid by spending $324 million and using over 5,000 workers to wire 2 extremely remote villages in Quighai province located at altitudes of 13,100 ft.
India
Currently, all the villages in India have been electrified w.e.f. 29 April 2018 but it doesn't mean that all households are electrified. By India's own set standards, only 10% of households in a village must have electricity for it to be considered electrified. As of August 2018, 91% of the total households are electrified in India. Rural areas in India are electrified non-uniformly, with richer states being able to provide a majority of the villages with power while poorer states still struggling to do so.The Rural Electrification Corporation Limited was formed to specifically address the issue of providing electricity in all the villages across the country. Poverty, lack of resources, lack of political will, poor planning, and electricity theft are some of the major causes which have left many villages in India without electricity, while urban areas have enjoyed growth in electricity consumption and capacity. In order to drastically increase electrification rates, the Indian Government has set the target of 175GW of installed renewable energy by 2022 and mandated the electrification of over 18,000 villages. At the end of 2016, India had around 45.6GW of installed renewable energy with a vast amount of work and investment required to meet their lofty targets. The central government is increasingly trying to improve the dire conditions by investing heavily in biogas, solar as well as wind energy. Programs such as The JNN solar mission, and Pradhan Mantri Gram Vidyut Yojana is also known as the Saubhagya Scheme have been announced to fasten the pace of electrification and diversify the procedure. The work is also on-going for reducing wastage, providing better equipment and improving the overall infrastructure for electrical transmissions in villages.
The Saubhagya scheme was successfully in ensuring rapid expansion of the electricity infrastructure in India. Electricity infrastructure is now available within 50 meters of consumers' premises. The Government of India announced 100% electrification of all willing households in India in 2018. A deeper look into electrification rates across the country suggest that about 13% of household consumers still don't have electricity connections due to questions of affordability of grid electricity and poor quality of service. The majority of household consumers with a grid-based electricity connection have a low sanctioned load of 0–1 kW or 1–2 kW. Besides, disparity has also been noted in grid electricity access rate among agricultural and institutional consumers.
