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 .
94-538: The Lambeth Waterworks Company was a utility company supplying water to parts of south London in England . The company was established in 1785 with works in north Lambeth and became part of the publicly owned Metropolitan Water Board in 1904. The Lambeth Waterworks Company, founded by the Lambeth Waterworks Act 1785 ( 25 Geo. 3 . c. 89) to supply water to south and west London, established premises on
188-460: A company gains an added benefit by expanding its size. These economies are due to the presence of some resource or competence that is not fully utilized, or to the existence of specific market positions that create a differential advantage in expanding the size of the firms. That growth economies disappear once the scale size expansion process is completed. For example, a company that owns a supermarket chain benefits from an economy of growth if, opening
282-565: 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: 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
376-591: A differentiated demand with respect to the quality of the product, and assistance before and after the sale. Very different organizational forms can therefore co-exist in the same sector of activity, even in the presence of economies of scale, such as, for example, flexible production on a large scale, small-scale flexible production, mass production, industrial production based on rigid technologies associated with flexible organizational systems and traditional artisan production. The considerations regarding economies of scale are therefore important, but not sufficient to explain
470-421: A firm's costs, returns to scale describe the relationship between inputs and outputs in a long-run (all inputs variable) production function. A production function has constant returns to scale if increasing all inputs by some proportion results in output increasing by that same proportion. Returns are decreasing if, say, doubling inputs results in less than double the output, and increasing if more than double
564-526: 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
658-427: A more efficient division of labour. The economies of division of labour derive from the increase in production speed, from the possibility of using specialized personnel and adopting more efficient techniques. An increase in the division of labour inevitably leads to changes in the quality of inputs and outputs. Many administrative and organizational activities are mostly cognitive and, therefore, largely independent of
752-407: A new supermarket, it gets an increase in the price of the land it owns around the new supermarket. The sale of these lands to economic operators, who wish to open shops near the supermarket, allows the company in question to make a profit, making a profit on the revaluation of the value of building land. Overall costs of capital projects are known to be subject to economies of scale. A crude estimate
846-532: A power and utilities industry outlook report by Deloitte identified a number of trends for the utilities industry: Issues faced by public utilities include: Alternative pricing methods include: Utility stocks are considered stable investments because they typically provide regular dividends to shareholders and have more stable demand. 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
940-421: 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. Though it can be mentioned that these natural monopolies are handled or watched by a public utilities commission, or an institution that represents
1034-496: A product X is lower when a single firm instead of two separate firms produce it. See Economies of scope#Economics . Some of the economies of scale recognized in engineering have a physical basis, such as the square–cube law , by which the surface of a vessel increases by the square of the dimensions while the volume increases by the cube. This law has a direct effect on the capital cost of such things as buildings, factories, pipelines, ships and airplanes. In structural engineering,

#17328586077291128-484: 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. Due to
1222-547: A relationship somewhat similar to the square–cube law. In some productions, an increase in the size of the plant reduces the average variable cost, thanks to the energy savings resulting from the lower dispersion of heat. Economies of increased dimension are often misinterpreted because of the confusion between indivisibility and three-dimensionality of space. This confusion arises from the fact that three-dimensional production elements, such as pipes and ovens, once installed and operating, are always technically indivisible. However,
1316-461: A result, numerous studies have indicated that the procurement volume must be sufficiently high to provide sufficient profits to attract enough suppliers, and provide buyers with enough savings to cover their additional costs. However, Shalev and Asbjornse found, in their research based on 139 reverse auctions conducted in the public sector by public sector buyers, that the higher auction volume, or economies of scale, did not lead to better success of
1410-549: A slow return of capital ; last, technical difficulties can occur in the management of plurality of networks, example in the city subsoil . 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
1504-520: 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: However, such a system has its drawbacks. Excessive government intervention can lead to: Resource efficiency: Despite these limitations, utilities within

As part of this agreement, the EBRD will allocate funds for the implementation of a number of important projects aimed at: 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. In the United Kingdom and Ireland ,
1692-733: A unit of capacity of many types of equipment, such as electric motors, centrifugal pumps, diesel and gasoline engines, decreases as size increases. Also, the efficiency increases with size. Operating crew size for ships, airplanes, trains, etc., does not increase in direct proportion to capacity. (Operating crew consists of pilots, co-pilots, navigators, etc. and does not include passenger service personnel.) Many aircraft models were significantly lengthened or "stretched" to increase payload. Many manufacturing facilities, especially those making bulk materials like chemicals, refined petroleum products, cement and paper, have labor requirements that are not greatly influenced by changes in plant capacity. This
1786-440: A variety of organizational and business situations and at various levels, such as a production, plant or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis . The economic concept dates back to Adam Smith and
1880-445: Is a correlating relationship between a firm's total sales and underlying efficiency. Firms with higher productivity will always outperform a firm with lower productivity which will lead to lower sales. Through trade liberalization, organizations are able to drop their trade costs due to export growth. However, trade liberalization does not account for any tariff reduction or shipping logistics improvement. However, total economies of scale
1974-627: Is a historically contingent fact, and not essential to the nature of such enterprises. In the case of agriculture, for example, Marx calls attention to the sophistical nature of the arguments used to justify the system of concentrated ownership of land: Instead of concentrated private ownership of land, Marx recommends that economies of scale should instead be realized by associations : Alfred Marshall notes that Antoine Augustin Cournot and others have considered "the internal economies [...] apparently without noticing that their premises lead inevitably to

#17328586077292068-477: Is based on the exporters individual frequency and size. So large-scale companies are more likely to have a lower cost per unit as opposed to small-scale companies. Likewise, high trade frequency companies are able to reduce their overall cost attributed per unit when compared to those of low-trade frequency companies. Economies of scale is related to and can easily be confused with the theoretical economic notion of returns to scale. Where economies of scale refer to
2162-411: Is because labor requirements of automated processes tend to be based on the complexity of the operation rather than production rate, and many manufacturing facilities have nearly the same basic number of processing steps and pieces of equipment, regardless of production capacity. Karl Marx noted that large scale manufacturing allowed economical use of products that would otherwise be waste. Marx cited
2256-424: Is expanded, including the aspects concerning the development of knowledge and the organization of transactions, it is possible to conclude that economies of scale do not always lead to monopoly. In fact, the competitive advantages deriving from the development of the firm's capabilities and from the management of transactions with suppliers and customers can counterbalance those provided by the scale, thus counteracting

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
2444-442: Is one where the costs of production fall when the number of firms in the industry drops, but the remaining firms increase their production to match previous levels. Conversely, an industry exhibits an external economy of scale when costs drop due to the introduction of more firms, thus allowing for more efficient use of specialized services and machinery. Economies of scale exist whenever the total cost of producing two quantities of

A lone carmaker may be profitable, but even more so if they exported cars to global markets in addition to selling to the local market. Economies of scale also play a role in a " natural monopoly ". There is a distinction between two types of economies of scale: internal and external. An industry that exhibits an internal economy of scale
2632-608: Is saturating the regional market, thus having to ship products uneconomic distances. Other limits include using energy less efficiently or having a higher defect rate. Large producers are usually efficient at long runs of a product grade (a commodity) and find it costly to switch grades frequently. They will, therefore, avoid specialty grades even though they have higher margins. Often smaller (usually older) manufacturing facilities remain viable by changing from commodity-grade production to specialty products. Economies of scale must be distinguished from economies stemming from an increase in
2726-433: Is that if the capital cost for a given sized piece of equipment is known, changing the size will change the capital cost by the 0.6 power of the capacity ratio (the point six to the power rule ). In estimating capital cost, it typically requires an insignificant amount of labor, and possibly not much more in materials, to install a larger capacity electrical wire or pipe having significantly greater capacity. The cost of

Economies of scale is a concept that may explain patterns in international trade or in the number of firms in a given market.

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
3384-784: 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. 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.

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,
3572-511: The advantages of external economies linked to an increase in the production of an entire sector of activity. However, "those economies which are external from the point of view of the individual firm, but internal as regards the industry in its aggregate, constitute precisely the class which is most seldom to be met with." "In any case - Sraffa notes – in so far as external economies of the kind in question exist, they are not linked to be called forth by small increases in production," as required by

This stimulated a whole series of studies on the cases of imperfect competition in Cambridge. However, in the succeeding years Sraffa followed a different path of research that brought him to write and publish his main work Production of commodities by means of commodities ( Sraffa 1966 ).

Learning by doing implies improvements in the ability to perform and promotes the introduction of incremental innovations with a progressive lowering of average costs. Learning economies are directly proportional to the cumulative production ( experience curve ). Growth economies emerge if
4042-508: The capitalist system is therefore characterized by two tendencies, connected to economies of scale: towards a growing concentration and towards economic crises due to overproduction. In his 1844 Economic and Philosophic Manuscripts , Karl Marx observes that economies of scale have historically been associated with an increasing concentration of private wealth and have been used to justify such concentration. Marx points out that concentrated private ownership of large-scale economic enterprises

In the pulp and paper industry, it is economical to burn bark and fine wood particles to produce process steam and to recover the spent pulping chemicals for conversion back to a usable form. Large and more productive firms typically generate enough net revenues abroad to cover

For example, the California Public Utilities Commission (CPUC) 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.

In the same year the company purchased 16 acres (65,000 m) of land in Brixton and built a reservoir and works on Brixton Hill adjacent to Brixton Prison . Around the 1850s the quality of drinking water became a matter of public concern, and John Snow examined
4418-492: 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. Public utilities in Kazakhstan include heating, water supply, sewerage, electricity and communications systems. A report by

Marshall believes that there are factors that limit this trend toward monopoly, and in particular: Piero Sraffa observes that Marshall, in order to justify the operation of the law of increasing returns without it coming into conflict with the hypothesis of free competition, tended to highlight
4606-447: The cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time . A decrease in cost per unit of output enables an increase in scale that is, increased production with lowered cost. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control. Economies of scale arise in
4700-690: The cost of adding another customer is small, and duplication of facilities would be wasteful. As a result, utilities were either government monopolies, or if investor-owned, regulated by a public utilities commission . 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
4794-462: The economies of scale due to the increase in size do not depend on indivisibility but exclusively on the three-dimensionality of space. Indeed, indivisibility only entails the existence of economies of scale produced by the balancing of productive capacities, considered above; or of increasing returns in the utilisation of a single plant, due to its more efficient use as the quantity produced increases. However, this latter phenomenon has nothing to do with

#17328586077294888-434: The economies of scale which, by definition, are linked to the use of a larger plant. At the base of economies of scale there are also returns to scale linked to statistical factors. In fact, the greater of the number of resources involved, the smaller, in proportion, is the quantity of reserves necessary to cope with unforeseen contingencies (for instance, machine spare parts, inventories, circulating capital, etc.). One of

Private utilities, also called investor-owned utilities , are owned by investors , 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
5076-416: The essential services they provide. In recent decades several high-profile utility company bankruptcies have challenged this perception. 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,
5170-422: The factors underlying the ever-increasing concentration of capital. Marx observes that in the capitalist system the technical conditions of the work process are continuously revolutionized in order to increase the surplus by improving the productive force of work. According to Marx, with the cooperation of many workers brings about an economy in the use of the means of production and an increase in productivity due to
5264-410: The firm increase, the notions of increasing returns to scale and economies of scale can be considered equivalent. However, if input prices vary in relation to their quantities purchased by the company, it is necessary to distinguish between returns to scale and economies of scale. The concept of economies of scale is more general than that of returns to scale since it includes the possibility of changes in
5358-518: The firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale if and only if it has increasing returns to scale, has diseconomies of scale if and only if it has decreasing returns to scale, and has neither economies nor diseconomies of scale if it has constant returns to scale. In this case, with perfect competition in
5452-454: The firm is so big in one or more input markets that increasing its purchases of an input drives up the input's per-unit cost, then the firm could have diseconomies of scale in that range of output levels. Conversely, if the firm is able to get bulk discounts of an input, then it could have economies of scale in some range of output levels even if it has decreasing returns in production in that output range. In essence, returns to scale refer to
5546-435: The fixed costs associated with exporting. However, in the event of trade liberalization, resources will have to be reallocated toward the more productive firm, which raises the average productivity within the industry. Firms differ in their labor productivity and the quality of their products, so more efficient firms are more likely to generate more net income abroad and thus become exporters of their goods or services. There
5640-604: The founder of political economy as an autonomous discipline. John Stuart Mill , in Chapter IX of the First Book of his Principles, referring to the work of Charles Babbage (On the economics of machines and manufactories), widely analyses the relationships between increasing returns and scale of production all inside the production unit. In Das Kapital (1867), Karl Marx , referring to Charles Babbage , extensively analyzed economies of scale and concludes that they are one of

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). In order to ensure

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
5922-438: The idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite. Economies of scale often have limits, such as passing the optimum design point where costs per additional unit begin to increase. Common limits include exceeding the nearby raw material supply, such as wood in the lumber, pulp and paper industry . A common limit for a low cost per unit weight commodities
6016-479: The increase in the division of labour. Furthermore, the increase in the size of the machinery allows significant savings in construction, installation and operation costs. The tendency to exploit economies of scale entails a continuous increase in the volume of production which, in turn, requires a constant expansion of the size of the market. However, if the market does not expand at the same rate as production increases, overproduction crises can occur. According to Marx
6110-419: The individual phases of the production process. If the inputs are indivisible and complementary, a small scale may be subject to idle times or to the underutilization of the productive capacity of some sub-processes. A higher production scale can make the different production capacities compatible. The reduction in machinery idle times is crucial in the case of a high cost of machinery. A larger scale allows for

For instance, wholesale electricity generation markets, electric transmission networks, electricity retailing and customer choice, telecommunications , some types of public transit and postal services have become competitive in some countries and

The facilities were completed in 1852, and the Lambeth was joined there taking advantage of its pipes to the city by the Chelsea Waterworks Company . The facilities played a role in John Snow's statistical investigations during a cholera outbreak , the facility was further upriver than many other waterworks and hence had cleaner water, leading to fewer cholera deaths. However
6486-424: The marginalist theory of price. Sraffa points out that, in the equilibrium theory of the individual industries, the presence of external economies cannot play an important role because this theory is based on marginal changes in the quantities produced. Sraffa concludes that, if the hypothesis of perfect competition is maintained, economies of scale should be excluded. He then suggests the possibility of abandoning
6580-411: The output market the long-run equilibrium will involve all firms operating at the minimum point of their long-run average cost curves (i.e., at the borderline between economies and diseconomies of scale). If, however, the firm is not a perfect competitor in the input markets, then the above conclusions are modified. For example, if there are increasing returns to scale in some range of output levels, but
6674-475: The output. If a mathematical function is used to represent the production function, and if that production function is homogeneous , returns to scale are represented by the degree of homogeneity of the function. Homogeneous production functions with constant returns to scale are first degree homogeneous, increasing returns to scale are represented by degrees of homogeneity greater than one, and decreasing returns to scale by degrees of homogeneity less than one. If
6768-405: The presence of significant economies of scale. This contradiction, between the empirical evidence and the logical incompatibility between economies of scale and competition, has been called the 'Cournot dilemma'. As Mario Morroni observes, Cournot's dilemma appears to be unsolvable if we only consider the effects of economies of scale on the dimension of scale. If, on the other hand, the analysis
6862-450: The price of inputs when the quantity purchased of inputs varies with changes in the scale of production. The literature assumed that due to the competitive nature of reverse auctions , and in order to compensate for lower prices and lower margins, suppliers seek higher volumes to maintain or increase the total revenue. Buyers, in turn, benefit from the lower transaction costs and economies of scale that result from larger volumes. In part as
6956-569: The production of a given plant. When a plant is used below its optimal production capacity , increases in its degree of utilization bring about decreases in the total average cost of production. Nicholas Georgescu-Roegen (1966) and Nicholas Kaldor (1972) both argue that these economies should not be treated as economies of scale. The simple meaning of economies of scale is doing things more efficiently with increasing size. Common sources of economies of scale are purchasing (bulk buying of materials through long-term contracts), managerial (increasing
7050-416: 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. For example, if many companies are already offering electricity, the additional installation of
7144-400: The reasons firms appear is to reduce transaction costs . A larger scale generally determines greater bargaining power over input prices and therefore benefits from pecuniary economies in terms of purchasing raw materials and intermediate goods compared to companies that make orders for smaller amounts. In this case, we speak of pecuniary economies, to highlight the fact that nothing changes from
7238-502: 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

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. The result of these and other regulatory rulings was the eventual restructuring of

The first systematic analysis of the advantages of the division of labour capable of generating economies of scale, both in a static and dynamic sense, was that contained in the famous First Book of Wealth of Nations (1776) by Adam Smith , generally considered

When the size of the company and the division of labour increase, there are a number of advantages due to the possibility of making organizational management more effective and perfecting accounting and control techniques. Furthermore, the procedures and routines that turned out to be the best can be reproduced by managers at different times and places. Learning and growth economies are at
7614-427: The size of the company and the market structure. It is also necessary to take into account the factors linked to the development of capabilities and the management of transaction costs. External economies of scale tend to be more prevalent than internal economies of scale. Through the external economies of scale, the entry of new firms benefits all existing competitors as it creates greater competition and also reduces
7708-411: 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. However, this system also has its disadvantages. For example, the lack of competition can lead to
7802-563: The south bank of the River Thames close to the present site of Hungerford Bridge where the Royal Festival Hall now stands. The company's first water-intake lay on the south side of the river, supplied directly from the river. After complaints that the water was foul, the intake was moved to the middle of the river. The Company expanded to supply Kennington in 1802 and about this time replaced its wooden pipes with iron ones. In 1832
7896-446: The specialization of managers), financial (obtaining lower- interest charges when borrowing from banks and having access to a greater range of financial instruments), marketing (spreading the cost of advertising over a greater range of output in media markets ), and technological (taking advantage of returns to scale in the production function). Each of these factors reduces the long run average costs (LRAC) of production by shifting
7990-567: The state of waters in 1849. Parliament passed the Metropolis Water Act 1852 to "make provision for securing the supply to the Metropolis of pure and wholesome water". Under the act, it became unlawful for any water company to extract water for domestic use from the tidal reaches of the Thames after 31 August 1855, and from 31 December 1855 all such water was required to be "effectually filtered". The directors had already decided in 1847 to move
8084-669: 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. 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. They are regulated by Ofgem , Ofwat , Ofcom ,
8178-449: The strength of beams increases with the cube of the thickness. Drag loss of vehicles like aircraft or ships generally increases less than proportional with increasing cargo volume, although the physical details can be quite complicated. Therefore, making them larger usually results in less fuel consumption per ton of cargo at a given speed. Heat loss from industrial processes vary per unit of volume for pipes, tanks and other vessels in
8272-520: The telephone service having been considered a public utility, the FCC made broadband internet access a public utility in the United States. 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
8366-399: The tendency towards a monopoly inherent in economies of scale. In other words, the heterogeneity of the organizational forms and of the size of the companies operating in a sector of activity can be determined by factors regarding the quality of the products, the production flexibility, the contractual methods, the learning opportunities, the heterogeneity of preferences of customers who express
8460-518: 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. 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
8554-557: 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. Key players in the public utility sector include: Public utilities must pursue the following objective given the social responsibility their services attribute to them: The management of public utilities continues to be important for local and general governments . By creating, expanding, and improving upon public utilities,
8648-443: The utility sector is often part of a long-term buy-and-hold strategy. 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 . Should rates rise,
8742-417: The variation in the relationship between inputs and output . This relationship is therefore expressed in "physical" terms. But when talking about economies of scale, the relation taken into consideration is that between the average production cost and the dimension of scale. Economies of scale therefore are affected by variations in input prices. If input prices remain the same as their quantities purchased by
8836-556: The variation or constancy of returns. In 1947, DuPont engineer Roger Williams, Jr. (1930-2005) published a rule of thumb that costs of chemical process are roughly proportional to the tonnage in power ~0.6 . In the following decades it became widely adopted other engineering industries and terrestrial mining, sometimes (e. g., in electrical power generation) with modified exponential scaling factors. It has been noted that in many industrial sectors there are numerous companies with different sizes and organizational structures, despite
