Electricity Balancing Market Governance

Introduction

Electricity balancing market governance refers to the legal, regulatory, institutional, and market arrangements used to maintain a continuous balance between the production and consumption of electricity. Electricity has a special physical characteristic: in an interconnected power system, generation and consumption must remain closely balanced in real time. Significant imbalance can disturb system frequency, threaten grid stability, and, in serious circumstances, contribute to widespread outages.

The balancing market therefore operates as one of the final mechanisms for correcting differences between scheduled electricity positions and actual physical conditions. Transmission System Operators (TSOs) or system operators procure and activate balancing services from generators, storage facilities, demand-response providers, aggregators, and other eligible participants.

Modern balancing-market governance goes beyond technical grid operation. It concerns competition, transparency, price formation, market power, non-discriminatory access, renewable-energy integration, cross-border electricity exchanges, cybersecurity, regulatory oversight, and allocation of financial responsibility for imbalances.

The European Union provides one of the most developed legal frameworks. Regulation (EU) 2017/2195 establishing a guideline on electricity balancing creates common principles concerning balancing capacity, balancing energy, imbalance settlement, and European balancing platforms. ACER explains that TSOs operate balancing markets to correct mismatches between supply and demand and procure balancing services necessary to maintain system frequency.

Legal and Regulatory Framework

1. Electricity Balancing Regulation

Commission Regulation (EU) 2017/2195, commonly called the Electricity Balancing Regulation or EB Regulation, establishes detailed rules governing electricity balancing in the European Union.

Its objectives include:

increasing competition in balancing markets;

promoting cross-border exchange of balancing services;

improving operational security;

encouraging efficient price formation;

facilitating participation by demand response and renewable resources;

harmonising imbalance settlement;

creating European platforms for exchanging balancing energy; and

ensuring transparent and non-discriminatory market operation.

Balancing therefore combines system-security regulation with market regulation.

2. Regulation (EU) 2019/943

The EU Electricity Regulation supplements this structure by requiring balancing markets to operate according to principles of competition, transparency, technological neutrality, and non-discrimination.

The governance framework is intended to permit different technologies—including generation, electricity storage, variable renewable generation, and demand response—to compete for balancing opportunities according to their technical capabilities.

3. Institutional Governance

Several institutions participate in balancing-market governance.

Transmission System Operators (TSOs) maintain system balance and procure or activate balancing services.

National Regulatory Authorities (NRAs) supervise national electricity markets, approve methodologies where required, and protect competitive and consumer interests.

ACER performs important coordinating and decision-making functions where electricity-market questions extend across national boundaries.

ENTSO-E facilitates coordination among European transmission system operators and contributes to development and operation of European balancing arrangements.

This institutional division demonstrates that balancing governance is increasingly multi-level governance rather than purely national electricity regulation.

Key Issues and Principles

1. Real-Time System Security

The fundamental objective is maintaining electricity-system frequency and reliability.

Market participants submit schedules and trading positions before electricity is physically delivered. Actual generation or consumption may nevertheless differ because of weather changes, plant failures, forecasting errors, renewable variability, unexpected demand, or transmission constraints.

Balancing mechanisms permit system operators to correct these differences.

Consequently, balancing-market rules must reconcile two objectives:

market efficiency and physical system security.

Where the two conflict, maintaining secure grid operation remains fundamental.

2. Balance Responsibility

A central governance principle is that market participants should generally bear responsibility for the imbalances they cause.

A Balance Responsible Party (BRP) therefore has incentives to keep its actual production or consumption reasonably consistent with its contractual or scheduled position.

Imbalance settlement prices are important because badly designed prices may weaken incentives for accurate forecasting, whereas efficient imbalance prices encourage participants to manage their positions properly.

3. Balancing Service Providers

Balancing Service Providers (BSPs) offer resources capable of helping the system operator restore balance.

These resources can include:

conventional generating units;

renewable-energy facilities;

batteries and other storage systems;

industrial loads;

demand-response resources; and

aggregated distributed resources.

Modern governance increasingly supports technology-neutral participation rather than reserving balancing services for large conventional generators.

4. Competitive Procurement

Balancing capacity and balancing energy should normally be procured through transparent and market-oriented arrangements.

Governance rules should prevent discrimination, preferential treatment, artificial barriers to entry, and unjustified technical requirements.

This becomes especially important as batteries, aggregators, flexible consumers, and distributed energy resources enter markets traditionally dominated by large generators.

5. Balancing Price Formation

Balancing prices perform two functions.

First, they compensate providers that supply balancing energy.

Second, they create economic signals concerning the real-time value of electricity and the cost of system imbalance.

Prices that are artificially suppressed may discourage flexibility investment. Conversely, poorly supervised scarcity pricing can create opportunities for market-power abuse.

ACER has specifically recognised that balancing markets can be structurally more concentrated than day-ahead and intraday markets because fewer assets can respond in real time and cross-zonal capacity may be limited. This creates legitimate concerns about potential market power.

6. Market Power and Regulatory Oversight

Balancing markets can create particular competition problems because TSOs may urgently require electricity or flexibility within a very short period.

A participant controlling a strategically located flexible generator or storage facility may therefore possess substantial temporary market power.

Governance consequently requires:

market monitoring;

transparency requirements;

bidding rules;

competition-law supervision;

surveillance against manipulation;

carefully designed price limits where legally justified; and

regulatory investigation of abnormal bidding behaviour.

The challenge is avoiding market manipulation without destroying legitimate scarcity-price signals.

7. Cross-Border Balancing

European electricity law increasingly treats balancing as a regional rather than exclusively national function.

European platforms permit balancing energy to be exchanged across borders. This can reduce overall balancing costs because one country's available flexible resources can help correct another country's imbalance.

Cross-border balancing nevertheless creates difficult governance questions concerning transmission capacity, congestion, settlement, regulatory jurisdiction, TSO responsibilities, platform operation, and allocation of costs.

8. Renewable Energy Integration

Wind and solar generation increase the importance of flexible electricity systems because their output depends partly upon changing weather conditions.

Balancing markets therefore play an important role in renewable-energy integration.

Storage, demand response, improved forecasting, flexible generation, aggregation, and cross-border balancing can collectively reduce the system costs associated with renewable variability.

Governance must therefore avoid rules that unnecessarily discriminate against renewable resources or newer flexibility technologies.

9. Transparency and Accountability

Balancing decisions can involve substantial amounts of money and may directly affect wholesale electricity prices.

Accordingly, governance should require transparent methodologies for:

procurement;

activation;

pricing;

settlement;

capacity allocation;

platform operation; and

calculation of imbalance charges.

Regulatory decisions must also contain adequate reasons so that affected participants can understand and, where permitted, challenge them.

Important Case Laws

1. Austrian Power Grid AG and Others v ACER

General Court of the European Union, 15 February 2023

This litigation concerned ACER decisions relating to implementation frameworks for European platforms exchanging balancing energy from automatic and manual frequency restoration reserves.

The disputes raised fundamental questions about the distribution of powers among TSOs, national regulators, and ACER.

The litigation demonstrates that European balancing platforms are not merely technical arrangements. Their design involves legally enforceable decisions concerning platform functions, regulatory authority, and cross-border capacity.

Principle: Balancing-market integration may legitimately involve supranational regulatory governance where national electricity systems are technically and economically interconnected.

2. Polskie Sieci Elektroenergetyczne and Others v ACER

Joined Cases C-281/23 P and C-282/23 P

These proceedings developed from disputes concerning European platforms for exchanging balancing energy from manual and automatic frequency restoration reserves.

Among the important questions were the interpretation of Articles 20, 21 and 37 of Regulation 2017/2195 and the treatment of functions necessary for operation of the balancing platforms, including issues connected with cross-zonal capacity.

The litigation also raised questions regarding the intensity of review exercised over ACER's regulatory decisions.

Principle: The governance of integrated balancing markets requires a legally defined allocation of responsibilities between system operators and regulatory institutions; technical platform design remains subject to administrative and judicial review.

3. Swissgrid AG v European Commission

Case C-121/23 P, Court of Justice, 13 February 2025

Swissgrid challenged matters concerning Switzerland's participation in European platforms for exchanging balancing energy.

Regulation 2017/2195 permits participation by Swiss TSOs only under specified legal conditions. The Court's proceedings concerned, among other matters, whether the Commission communication at issue constituted a challengeable act.

The case illustrates the connection between balancing-market governance, international electricity cooperation, market integration, and judicial review.

Principle: Participation in cross-border balancing arrangements is governed not merely by engineering feasibility but also by formal legal and institutional requirements.

4. Swissgrid AG v ACER

General Court, Case T-557/23, 8 October 2025

This later litigation concerned Swissgrid and the European platform for exchanging balancing energy from manually activated frequency restoration reserves.

The case addressed access to ACER's appeal mechanisms and the requirement of standing, including whether the applicant was directly concerned by the relevant regulatory measure.

Principle: Effective balancing-market governance includes procedural governance. Market participants must satisfy legal requirements of standing and admissibility before regulatory decisions can be challenged.

5. RWE Supply & Trading GmbH v ACER

Case T-487/24

This dispute concerns ACER's approach to technical and transitional price limits applicable to balancing energy.

RWE argued, among other matters, that the relevant limits interfered with free price formation, created market-entry barriers, and were insufficiently justified. The proceedings therefore illustrate the difficult regulatory balance between unrestricted price formation and safeguards necessary for an integrated balancing market.

Principle: Regulatory intervention in balancing prices must have a lawful basis, pursue legitimate market objectives, and satisfy requirements of adequate reasoning and proportionality.

6. Associated Electric Cooperative, Inc. v FERC

United States Court of Appeals for the Eighth Circuit, 2024

The dispute involved payment for emergency electricity supplied between balancing authorities and whether the relevant market tariff and market-participation agreement governed the transaction.

The court accepted FERC's conclusion that the applicable tariff controlled the emergency-energy transaction and rejected attempts to separate balancing-authority personnel from power-marketing functions in a manner unsupported by the governing agreements.

Principle: Electricity-balancing transactions remain governed by approved tariffs and market agreements even where emergency operational circumstances exist. System reliability does not automatically displace established regulatory and contractual pricing rules.

Governance Challenges

Electricity balancing governance faces several emerging challenges.

The first is decentralisation. Millions of batteries, electric vehicles, smart appliances, distributed generators, and flexible consumers may eventually provide balancing services.

The second is digitalisation. Automated bidding, artificial intelligence, smart meters, forecasting algorithms, and real-time data platforms increasingly influence balancing decisions.

The third is renewable variability. Higher renewable penetration increases the economic value of flexibility and fast-response resources.

The fourth is cross-border integration. National regulatory systems must cooperate where balancing energy flows through interconnected European networks.

The fifth is market concentration. Real-time balancing markets may contain fewer available suppliers than ordinary wholesale markets, creating stronger possibilities for temporary market power.

The sixth is regulatory accountability. Because technical methodologies can significantly affect market prices and participant rights, regulatory bodies must provide clear legal reasoning and remain subject to appropriate administrative and judicial review.

Conclusion

Electricity balancing market governance represents the intersection of electricity law, competition law, administrative law, market regulation, and power-system engineering. Its fundamental purpose is to ensure that electricity supply and demand remain balanced while allowing the necessary flexibility to be obtained efficiently through competitive markets.

Modern governance has moved from nationally controlled balancing arrangements toward interconnected and increasingly harmonised systems. The EU framework particularly demonstrates this transformation through common balancing rules, European platforms, TSO cooperation, national regulatory supervision, and ACER oversight.

The emerging case law—including Austrian Power Grid v ACER, Polskie Sieci Elektroenergetyczne v ACER, Swissgrid v Commission, Swissgrid v ACER, RWE Supply & Trading v ACER, and Associated Electric Cooperative v FERC—shows that balancing is no longer simply a technical matter for electricity engineers. Questions concerning platform governance, regulatory competence, price limits, cross-border participation, tariffs, standing, competition, and judicial review have become central legal issues.

Ultimately, effective balancing-market governance must achieve three objectives simultaneously: real-time system security, economically efficient market operation, and legally accountable regulatory decision-making. As renewable generation, storage, demand response, electric vehicles, and digital technologies expand, the balancing market is likely to become one of the most important areas of modern electricity regulation.
