Analyzing competition in the energy sector presents significant challenges due to its structural complexity and the need for extensive regulation for efficient operation. Unlike other economic sectors, where regulation tends to decrease with liberalization, in the energy sector, liberalization leads to a greater quantity and complexity of regulations. This complexity often confuses observers outside the industry, leading them to make errors in their analysis and recommendations when applying competition models from other sectors.
There are two main types of problems in competition analyses in our sector. On the one hand, there are structural problems , which consist of differentiating between activities that are natural monopolies due to their technical and economic characteristics, such as those related to network infrastructure, which exhibit clear economies of scale (for example, transmission and distribution), and those that can be offered competitively, such as generation, marketing, the provision of flexibility services (e.g., storage, aggregators, virtual power plants – VPPs), the provision of charging infrastructure, and the provision of other energy services. On the other hand, there are problems related to the behavior and protection of free competition against the abuse of market power by companies in liberalized activities.
Experience has shown that the key to resolving competition problems in activities with characteristics of natural monopolies is to address structural issues such as the total or partial separation (whether of ownership, accounting, legal, or management) of these activities from those that can compete in the market. This is called vertical disintegration and is done to prevent cross-subsidies, thus ensuring fair competition in competitive activities and preventing the transfer of risks from liberalized to regulated activities.
On the other hand, in activities offered in competition through a market, problems are solved by promoting competition, eliminating barriers to entry and exit, monitoring anti-competitive conduct and behavior, and, in some cases, depending on the design of the wholesale market adopted, limiting market power to prevent abuses of dominant position.
It is important to emphasize that these solutions may not be appropriate for island energy systems or small, isolated countries. In these cases, the benefits of competition may not outweigh the efficiency losses and additional costs generated by vertical disintegration. In these situations, the best strategy has been the proper regulation of a natural monopoly throughout the entire value chain. This also entails creating a robust regulatory framework that ensures the effectiveness, transparency, and accountability of the regulated monopoly.
Network Infrastructure Activities
The approaches adopted in regulating activities with characteristics of a natural monopoly (transmission and distribution) differ from country to country. Generally, regulation seeks to incentivize efficiency by decoupling the company’s actual costs from its revenue over a regulatory period of several years, typically four or five. In all schemes, network users must be charged tolls that cover the remuneration for the corresponding network activity. In this regard, the regulatory framework for these activities includes mechanisms to:
- Guaranteeing free access : Network ownership does not imply exclusive use. A third party must be able to access the economic efficiency derived from the existence of a single network made available to all agents through guaranteed access and the payment of known and non-arbitrary tolls.
- Price regulation: To prevent monopolies from imposing excessively high prices, pricing systems can be used based on incurred costs plus a reasonable profit margin or by comparing prices with efficient benchmark companies, thus protecting consumers from excessive tariffs.
- Service quality: To ensure that the monopoly provides quality service to consumers, minimum service reliability standards are typically defined. These standards are based on widely adopted indices such as SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index), and CAIDI (Customer Average Interruption Duration Index). For more details, see the following link: IEEE – Reliability Indices
- Investment: To incentivize the monopoly to invest in the infrastructure and technology necessary to meet consumer demand and needs, specific investment obligations are established for the network owner, in terms of geographic coverage, network capacity, or adoption of new technologies. In all cases, reasonable returns on investment are permitted.
- Consumer protection : To prevent consumers from being abused by monopolies, mechanisms are created to resolve disputes fairly and quickly. Additionally, an independent body is entrusted with the task of defending consumer interests.
Activities Subject to Competition
The level of competition in wholesale electricity markets varies depending on the design adopted. In those that follow the bid-ask or “pool” pricing system, influenced by the British liberal model and later adopted in others such as California and Colombia, there is a risk of price manipulation. To address this problem, authorities typically establish limits on market concentration by a single player and even set maximum prices to prevent abuses of dominant position.
In contrast, in markets that apply the “Audited Variable Cost Declaration” scheme, inspired by the more conservative design of the Chilean market of 1981 (the world’s first liberalized market) and adopted in others such as the Argentine, Panamanian and most Latin American electricity markets, the aim is to avoid speculation on production capacity and supply prices through regulations and market design.
In Latin America, the Chilean model is the most common, although there are exceptions such as Colombia, which leans toward the British model. The main difference between these systems lies in the fact that the Chilean model guarantees competitive conditions through strict regulation of operating rules and pricing, while the British model relies on market forces for the free establishment of prices in the spot market. However, experience with both models has demonstrated the importance of ex-post monitoring to track competition and identify and penalize anti-competitive behavior that may arise in the market dynamics. Below is an example of this type of competition monitoring report for the Chilean electricity market: Competition Monitoring Report 2023 .
Market Concentration vs Market Power
Market concentration and market power are fundamental concepts in competitive analysis in any industry. While market concentration is a key indicator, it is not sufficient on its own to determine whether an agent has market power and is violating competition rules in its sector.
Market concentration simply indicates how market share is divided among the different players in an industry. It is an initial tool used to assess how close a market is to the theoretical situation of perfect competition or monopoly. On the other hand, market power implies the ability of a player to influence market conditions in their favor, whether by raising prices, restricting production, or excluding competitors. Systematically violating these basic rules, particularly through the abuse of market power by a player, is a clear sign of weakening free competition in a market.
The causes of market concentration can be diverse, and its impacts can be both beneficial and detrimental. Let’s examine these aspects in more detail:
Causes of Market Concentration
- Barriers to entry: These make it difficult for new companies to enter the market, whether due to high investment costs, restrictive regulations, or problems related to intellectual property.
- Economies of scale: As companies increase their production, they can gain benefits that give them a competitive advantage over smaller companies.
- Mergers and acquisitions: When two or more companies merge or one acquires another, the number of competitors in the market is reduced.
Consequences of Market Concentration
Positive:
- Greater efficiency: Companies with a large market share can achieve economies of scale, allowing them to produce at a lower cost.
- Innovation: Dominant companies tend to invest more in research and development, which can result in the creation of improved products or services.
Negative:
- Higher prices: Companies with market power can raise prices without worrying about losing customers due to a lack of competition.
- Less variety: With fewer competitors in the market, consumers may have fewer options to choose from among products or services.
- Less competition: The reduction in the number of competitors can decrease the incentive for companies to innovate and improve the quality of their products or services.
In summary, high concentration alone is not a definitive indicator of anticompetitive activity. A highly concentrated market can be perfectly competitive, provided there are low barriers to entry and effective regulation to prevent anticompetitive conduct. In fact, in markets with a small number of firms, competition can be vigorous if these firms have incentives to innovate, reduce costs, and offer better products or services to consumers.
In this sense, it is not the possession of market power, but its abuse, that constitutes an anticompetitive practice, which may be subject to sanctions. To determine whether an agent exercises market power, it is necessary to analyze a series of key factors:
- Definition of Relevant Market : This concept refers to the space where competitors interact directly to satisfy consumer needs. Determining the relevant market considers several aspects, such as the type of product or service offered, consumer characteristics, geography, and barriers to entry.
- Market share : Although a company’s market share is important, it is not the determining factor on its own.
- Barriers to entry and exit : The difficulties for new companies to enter the market or for existing companies to leave it can give power to established companies.
- Business conduct : Actions such as predatory pricing, collusive agreements, or price discrimination can be indicators of market power.
- Negotiating power : A company’s ability to influence the prices of its inputs or the terms of sale of its products can also be a relevant factor.
In practice, competition authorities use various tools to assess market power and combat anticompetitive practices. These tools include:
- Analysis of concentration indices: Calculation of market power indicators such as the Herfindahl-Hirschman Index (HHI), the k-company concentration ratio, the Lerner Index, the Pivotal Supplier Index, the Residual Supply Index, the Rothschild-Hirschman Concentration Index (CRn), among others.
- Market research: Research is conducted to understand market dynamics, business behavior, and the impact on consumers.
- Analysis of specific cases: Complaints are investigated or investigations are carried out ex officio regarding possible anti-competitive practices.
In summary, competition policy aims to foster dynamic and efficient markets where businesses compete on a level playing field and consumers have access to a wide range of products and services at fair prices. It is crucial to remember that this is an ongoing process requiring constant oversight by authorities and collaboration from various stakeholders, including businesses, consumers, and academics.
Competitive Analysis in the Digital Age
In the energy sector, digitalization is enabling the emergence of new forms of energy generation, distribution, and trading, as well as the implementation of smart grid management systems and the introduction of distributed energy resources. These advances are democratizing access to energy and fostering increased competition by facilitating the entry of new players into the market. Among the main opportunities that digitalization is bringing to competition are:
- Greater efficiency and transparency: Digitalization can improve the efficiency of the energy market by optimizing the management of demand, the grid, and generation. Data transparency can improve consumer decision-making and facilitate market oversight by authorities.

- New products and services: Digitalization can lead to innovative new energy products and services, such as real-time demand management and peer-to-peer energy trading.
The digital age is also posing challenges in terms of market concentration and market power for those companies that are dominating technologies and certain aspects of the modern energy value chain, such as data management, trading platforms, and the provision of energy services . Some of the main challenges that can be highlighted are:
- New players and business models: Digitalization facilitates the entry of new players into the market, such as prosumers and energy trading platforms (demand aggregators). This can fragment the market and make it more difficult to implement traditional regulatory frameworks.
- Complexity and information asymmetries: The large amount of data generated by digital assets and the decentralization of production can create information asymmetries between market players, hindering fair competition.
Strategies for Navigating the New Energy Era
To ensure fair competition and promote innovation in this new era, it is essential that regulatory authorities adopt proactive and flexible strategies that promote the interoperability of systems and data, foster transparency in the use of data and algorithms, and establish clear standards for privacy protection and information security. Some of the strategies being adopted in various markets and that are recommended include:
- Proactive Regulation: Regulatory authorities must anticipate the potential impacts of digitalization on competition and act proactively to prevent anti-competitive practices. This entails a constant review of regulations to address the new challenges arising from digital technology. The European Union has implemented the General Data Protection Regulation (GDPR) to establish data protection standards for companies operating in the single market.
- Equitable Access to Digital Infrastructure: It is crucial to ensure that all market participants have equitable access to the digital infrastructure necessary to participate in the energy sector. This includes promoting open standards and system interoperability to avoid artificial barriers to entry.
- Transparency in Data Use: Companies operating in the energy sector must be transparent in their use of data, especially regarding the collection, storage, and analysis of consumer data. Regulatory authorities must establish clear standards for protecting privacy and ensuring data security.
- Promoting Competition in Digital Services: Competition should be fostered in digital services related to the energy sector, such as online trading platforms, energy management applications, and cloud-based services. This can be achieved through policies that facilitate the entry of new players into the market and promote innovation in digital services.
- Intersectoral Cooperation : The digitalization of the energy sector is closely linked to other sectors, such as information technology, telecommunications, and urban mobility. Therefore, it is important to foster collaboration between these sectors to fully leverage the potential of digitalization and ensure a transition to a more sustainable and efficient energy system.
- Education and Awareness: It is essential to educate consumers about the benefits of digitalization in the energy sector and how they can take advantage of new technologies to reduce their energy consumption, improve efficiency and contribute to the transition to cleaner and renewable energy sources.
