A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to statewide government monopolies.

Public utilities are meant to supply goods and services that are considered essential; water, gas, electricity, telephone, waste disposal, and other communication systems represent much of the public utility market. The transmission lines used in the transportation of electricity, or natural gas pipelines, have natural monopoly characteristics. A monopoly can occur when it finds the best way to minimize its costs through economies of scale to the point where other companies cannot compete with it.^[1] For example, if many companies are already offering electricity, the additional installation of a power plant will only disadvantage the consumer as prices could be increased. If the infrastructure already exists in a given area, minimal benefit is gained through competing. In other words, these industries are characterized by economies of scale in production.^[2] Though it can be mentioned that these natural monopolies are handled or watched by a public utilities commission, or an institution that represents the government.^[1]

There are many different types of public utilities. Some, especially large companies, offer multiple products, such as electricity and natural gas. Other companies specialize in one specific product, such as water. Modern public utilities may also be partially (or completely) sourced from clean and renewable energy in order to produce sustainable electricity. Of these, wind turbines and solar panels are those used most frequently.

Whether broadband internet access should be a public utility is a question that was being discussed with the rise of internet usage. This is a question that was being asked due to the telephone service being considered a public utility. Since arguably broadband internet access has taken over telephone service, perhaps it should be a public utility. The Federal Communications Commission (FCC) in the United States in 2015 made their stance on this issue clear.^[1] Due to the telephone service having been considered a public utility, the FCC made broadband internet access a public utility in the United States.^[1]

Public utilities have historically been considered to be a natural monopoly. This school of thought holds that the most cost-efficient way of doing business is through a single firm because these are capital-intensive businesses with unusually large economies of scale and high fixed costs associated with building and operating the infrastructure, e.g. power plants, telephone lines and water treatment facilities.^[3] However, over the past several decades, traditional public utilities' monopoly position has eroded. For instance, wholesale electricity generation markets, electric transmission networks,^[4] electricity retailing and customer choice,^[5] telecommunications, some types of public transit and postal services have become competitive in some countries and the trend towards liberalization, deregulation and privatization of public utilities is growing. However, the infrastructure used to distribute most utility products and services has remained largely monopolistic.^{[citation needed]}

Key players in the public utility sector include:^[6]

• Generators produce or collect the specific product to be used by customers: for example, electricity or water.
• Network operators (grid operators, regional network operators, and distribution network operators) sell access to their networks to retail service providers, who deliver the product to the end user.
• Traders and marketers buy and sell the actual product and create further complex structured products, combined services and derivatives products. Depending on the product structure, these companies may provide utilities and businesses with a reliable supply of a product like electricity at a stable, predictable price, or a shorter term supply at a more volatile price.
• Service providers and retailers are the last segment in the supply chain, selling directly to the final consumer. In some markets, final consumers can choose their own retail service provider.

Public utilities must pursue the following objective given the social responsibility their services attribute to them:

• Ensuring services are of the highest quality and responsive to the needs and wishes of patients;
• Ensuring that health services are effectively targeted so as to improve the health of local populations;
• Improving the efficiency of the services so the volume of well-targeted effective services is the widest, given the available resources.^[7]

The management of public utilities continues to be important for local and general governments. By creating, expanding, and improving upon public utilities, a governmental body may attempt to improve its image or attract investment. Traditionally, public services have been provided by public legal entities, which operate much like corporations, but differ in that profit is not necessary for a functional business. A significant factor in government ownership has been to reduce the risk that an activity, if left to private initiative, may be considered not sufficiently profitable and neglected. Many utilities are essential for human life, national defense, or commerce, and the risk of public harm with mismanagement is considerably greater than with other goods. The principle of universality of utilities maintains that these services are best owned by, and operating for, the public. The government and the society itself would like to see these services being economically accessible to all or most of the population. Furthermore, other economic reasons based the idea: public services need huge investments in infrastructures, crucial for competitiveness but with a slow return of capital; last, technical difficulties can occur in the management of plurality of networks, example in the city subsoil.^[7]

Public pressure for renewable energy as a replacement for legacy fossil fuel power has steadily increased since the 1980s. As the technology needed to source the necessary amount of energy from renewable sources is still under study, public energy policy has been focused on short term alternatives such as natural gas (which still produces substantial carbon dioxide) or nuclear power. In 2021 a power and utilities industry outlook report by Deloitte identified a number of trends for the utilities industry:

• Enhanced competition, sparked by regulations such as FERC's Order 2222 that open up the market to smaller, innovative firms using renewable energy sources, like wind or solar power
• Expansions in infrastructure, to manage new renewable energy sources
• Greater electrification of transportation, and longer-range batteries for cars and trucks
• Oil companies and other traditional-energy players entering the renewable-energy field
• A greater emphasis on disaster readiness^[8]

Issues faced by public utilities include:

• Service area: regulators need to balance the economic needs of the companies and the social equity needed to guarantee to everyone the access to primary services.
• Autonomy: Economic efficiency requires that markets be left to work by themselves with little intervention. Such instances are often not equitable for some consumers that might be priced out of the market.
• Pricing: Equity requires that all citizens get the service at a fair price.^[9]

Alternative pricing methods include:^{[citation needed]}

• Average production costs: the utility calculates the break-even point and then set the prices equal to average costs. The equity issue is basically overcome since most of the market is being served. As a defect regulated firms do not have incentives to minimize costs.
• Rate of return regulation: regulators let the firms set and charge any price, as long as the rate of return on invested capital does not exceed a certain rate. This method is flexible and allows for pricing freedom, forcing regulators to monitor prices. The drawback is that this method could lead to overcapitalization. For example, if the rate of return is set at five percent, then the firm can charge a higher price simply by investing more in capital than what it is actually needed (i.e., 5% of $10 million is greater than 5% of $6 million).
• Price cap regulation: regulators directly set a limit on the maximum price. This method can result in a loss of service area. One benefit of this method is that it gives firms an incentive to seek cost-reducing technologies as a strategy to increase utility profits.

Utility stocks are considered stable investments because they typically provide regular dividends to shareholders and have more stable demand.^[10] Even in periods of economic downturns characterized by low interest rates, such stocks are attractive because dividend yields are usually greater than those of other stocks, so the utility sector is often part of a long-term buy-and-hold strategy.^[6]

Utilities require expensive critical infrastructure which needs regular maintenance and replacement. Consequently, the industry is capital intensive, requiring regular access to the capital markets for external financing. A utility's capital structure may have a significant debt component, which exposes the company to interest rate risk.^[11] Should rates rise, the company must offer higher yields to attract bond investors, driving up the utility's interest expenses. If the company's debt load and interest expense becomes too large, its credit rating will deteriorate, further increasing the cost of capital and potentially limiting access to the capital markets.^[12]

Public utilities in Kazakhstan include heating, water supply, sewerage, electricity and communications systems.

• They are mainly represented by centralized networks, with the exception of some rural areas.
• Various types of fuels are used, including coal, natural gas and fuel oil.
• Many systems need to be upgraded to increase their efficiency and reduce their environmental impact.

• They provide the population with drinking and industrial water.
• The sources of water are rivers, lakes and groundwater.
• The level of water quality in some regions is of concern.
• It is necessary to increase the efficiency of water resources use and improve water quality.

• Wastewater is diverted from residential and industrial facilities.
• The level of wastewater treatment in some regions does not meet modern standards.
• Sewerage systems need to be expanded and upgraded to protect the environment.

• It is provided by power plants running on various types of fuels, including coal, natural gas, hydropower and nuclear energy.
• There are problems with power outages, especially in rural areas.
• It is necessary to modernize the power grid and increase their efficiency.
• The heating, water supply and sewerage systems of Kazakhstan, although functioning, require urgent modernization. The technical capabilities of these networks are becoming outdated, which leads to an increase in operating costs and a decrease in their reliability.

A report by the European Bank for Reconstruction and Development (EBRD) notes that additional investments are needed to improve the efficiency and reliability of these systems.^[13]

The analysis conducted by the EBRD revealed a number of problems faced by heating, water supply and sewerage systems in Kazakhstan.

• Outdated technologies: In many cases, the infrastructure has exhausted its resource and needs to be replaced.
• Low energy efficiency: Existing systems consume a lot of energy, which leads to unjustified costs.
• Unreliability: Worn-out networks often fail, which leads to interruptions in the supply of water and heat, as well as leaks.

The report also provides examples of cities where networks are being upgraded with the support of the EBRD. These projects demonstrate how the introduction of modern technologies can improve the efficiency, reliability and environmental friendliness of heating, water supply and sewerage systems.

Upgrading infrastructure is not just a matter of convenience. It is of vital importance for public health, environmental protection and ensuring the sustainable development of the economy of Kazakhstan.

In most cases, public utilities in Kazakhstan are state-owned, which means that their activities are directly regulated by akimats. This creates a system with an administrative nature of relations, where the authorities have the authority to issue mandatory instructions for these companies.

Proponents of such a system emphasize that it allows the authorities to directly influence the commercial activities of public utilities, ensuring their compliance with state interests. This can be expressed in:

• Tariff control: Akimats can set tariffs for housing and communal services, making them accessible to the public.
• Ensuring the quality of services: The State can influence the standards of service by ensuring the provision of public services of appropriate quality.
• Implementation of social programs: Public utilities can participate in social programs aimed at supporting vulnerable segments of the population.

However, such a system has its drawbacks. Excessive government intervention can lead to:

• Reduced efficiency: Bureaucratic procedures and restrictions in decision-making can slow down the work of enterprises and hinder the introduction of innovations.
• Unreasonable expenses: Administrative barriers and inefficient management can lead to an increase in inappropriate expenses.
• Limiting investments: The uncertainty of government policy and the risks of interference from akimats may deter potential investors.

Resource efficiency:

Despite these limitations, utilities within the framework of this system can demonstrate high efficiency in the use of labor resources and management costs.^[13]

Residents of Kazakhstan receive water, sewerage and heating from companies recognized by the state as natural monopolies. This means that there is no competition in these areas, and tariffs are set by a special state body – the Committee for Regulation of Natural Monopolies, Competition and Consumer Protection (CRNM and CP).^[14][15]

In order to ensure the smooth operation of public utilities, the state also controls the investment programs of monopolistic companies. This is handled by the Committee on Construction and Housing and Communal Services. Such a system allows you to regulate prices for utilities and direct investments to infrastructure development.^[16] However, this system also has its disadvantages. For example, the lack of competition can lead to a decrease in the efficiency of monopolistic companies.

To protect the interests of consumers from unjustified overpricing and substandard service, there are special regulatory bodies whose powers are regulated by the Law "On Natural Monopolies" and other regulatory acts.

Main functions:

• Investment promotion: Development of tariff calculation methods that are attractive to both consumers and private investors interested in investing in the modernization of public infrastructure.^[17]
• Control over the use of funds from IFIs: Determining the specifics of regulating the activities of natural monopolies that attract financing from international financial institutions (IFIs). This allows you to track the intended use of borrowed funds.^[18]
• Formation of a transparent tariff policy: Establishment of rules obliging monopolistic companies to publicly disclose information about tariffs, as well as infrastructure development plans.^[19]
• Analysis of investment programs: Evaluation of investment programs of natural monopolies, approval of development plans and control over their implementation.^[20]

Interaction at different levels:

It is important to note that the powers to regulate the activities of natural monopolies are distributed between federal and local authorities.  Effective coordination of their actions is necessary to ensure coordinated work and achieve common goals.

As a result, the activities of the regulatory authorities of natural monopolies are aimed at ensuring a balance between the interests of consumers, utility companies and the state.

2017 was marked by a new round of cooperation between Kazakhstan and the European Bank for Reconstruction and Development (EBRD). The parties signed a three-year agreement with the aim of working together to modernize the country's infrastructure.

As part of this agreement, the EBRD will allocate funds for the implementation of a number of important projects aimed at:

• Improving urban infrastructure: Upgrading water supply, sewerage, heating and other vital facilities will be a priority.
• Optimization of customs procedures: Joint efforts will be made to simplify customs processes, which should lead to stimulating trade and accelerating economic growth.

In addition to these two key areas, the EBRD will continue to support other initiatives aimed at improving the well-being of citizens of Kazakhstan.^[13]

In the United Kingdom and Ireland, the state, private firms, and charities ran the traditional public utilities. For instance, the Sanitary Districts were established in England and Wales in 1875 and in Ireland in 1878.^{[citation needed]}

The term can refer to the set of services provided by various organizations that are used in everyday life by the public, such as: electricity generation, electricity retailing, electricity supplies, natural gas supplies, water supplies, sewage works, sewage systems and broadband internet services.^[21] They are regulated by Ofgem, Ofwat, Ofcom, the Water Industry Commission for Scotland and the Utility Regulator in the United Kingdom, and the Commission for Regulation of Utilities and the Commission for Communications Regulation in the Republic of Ireland. Disabled community transport services may occasionally be included within the definition. They were mostly privatised in the UK during the 1980s.

The first public utility in the United States was a grist mill erected on Mother Brook in Dedham, Massachusetts, in 1640.^[22]

In the U.S., public utilities provide services at the consumer level, be it residential, commercial, or industrial consumer. Utilities, merchant power producers and very large consumers buy and sell bulk electricity at the wholesale level through a network of regional transmission organizations (RTO) and independent system operators (ISO) within one of three grids, the Eastern Interconnection, the Texas Interconnection, which is a single ISO, and the Western Interconnection.^{[citation needed]}

U.S. utilities historically operated with a high degree of financial leverage and low interest coverage ratios compared to industrial companies. Investors accepted these credit characteristics because of the regulation of the industry and the belief that there was minimal bankruptcy risk because of the essential services they provide. In recent decades several high-profile utility company bankruptcies have challenged this perception.^[23]

Public utilities were historically regarded as natural monopolies because the infrastructure required to produce and deliver a product such as electricity or water is very expensive to build and maintain. Once assets such as power plants or transmission lines are in place, the cost of adding another customer is small, and duplication of facilities would be wasteful.^[24] As a result, utilities were either government monopolies, or if investor-owned, regulated by a public utilities commission.^[25][26]

In the electric utility industry, the monopoly approach began to change in the 1990s. In 1996, the Federal Energy Regulatory Commission (FERC) issued its Order No. 888, which mandated that electric utilities open access to their transmission systems to enhance competition and "functionally unbundle" their transmission service from their other operations. The order also promoted the role of an independent system operator to manage power flow on the electric grid.^[27][28] Later, FERC Order No. 889 established an electronic information system called OASIS (open access same-time information system) which would give new users of transmission lines access to the same information available to the owner of the network.^[29] The result of these and other regulatory rulings was the eventual restructuring of the traditional monopoly-regulated regime to one in which all bulk power sellers could compete. A further step in industry restructuring, "customer choice", followed in some 19 states, giving retail electric customers the option to be served by non-utility retail power marketers.^[30][31][32]

Public utilities can be privately owned or publicly owned. Publicly owned utilities include cooperative and municipal utilities. Municipal utilities may actually include territories outside of city limits or may not even serve the entire city. Cooperative utilities are owned by the customers they serve. They are usually found in rural areas. Publicly owned utilities are non-profit.^{[citation needed]} Private utilities, also called investor-owned utilities, are owned by investors,^[33][34][35] and operate for profit, often referred to as a rate of return.

A public utilities commission is a governmental agency in a particular jurisdiction that regulates the commercial activities related to associated electric, natural gas, telecommunications, water, railroad, rail transit, and/or passenger transportation companies. For example, the California Public Utilities Commission (CPUC)^[36] and the Public Utility Commission of Texas regulate the utility companies in California and Texas, respectively, on behalf of their citizens and ratepayers (customers). These public utility commissions (PUCs) are typically composed of commissioners, who are appointed by their respective governors, and dedicated staff that implement and enforce rules and regulations, approve or deny rate increases, and monitor/report on relevant activities.^[37]

Ratemaking practice in the U.S. holds that rates paid by a utility's customers should be set at a level which assures that the utility can provide reliable service at reasonable cost.^[38]

Over the years, various changes have dramatically re-shaped the mission and focus of many public utility commissions. Their focus has typically shifted from the up-front regulation of rates and services to the oversight of competitive marketplaces and enforcement of regulatory compliance.^{[citation needed]}
