Deterrence-Based Electricity Enforcement

1. Introduction

Deterrence-based electricity enforcement means using legal enforcement powers to discourage electricity companies, generators, suppliers, traders and network operators from breaking electricity laws and regulatory rules. The basic idea is simple: if unlawful behaviour creates a real and predictable consequence, companies have a stronger reason to follow the rules.

In the UK, Ofgem uses enforcement to deal with breaches of electricity licences, regulations and market rules. Enforcement may include financial penalties, consumer redress, compliance requirements and other regulatory measures.

2. Why Deterrence Is Important in Electricity Law

Electricity is an essential service. A regulatory violation can affect thousands or millions of consumers. For example, unlawful market conduct may increase electricity prices, poor supplier practices may harm vulnerable consumers, and failures in network management may threaten electricity security.

Therefore, electricity enforcement has two purposes:

Correct the particular breach, and

Prevent similar conduct in the future.

The second purpose is the main idea behind deterrence.

3. Financial Penalties

The most common deterrence tool is the financial penalty. A penalty should be sufficiently meaningful so that a company does not regard unlawful conduct as simply another business expense.

Ofgem can impose substantial penalties for breaches of electricity licence conditions and relevant competition rules. In certain cases, penalties can reach up to 10% of turnover.

The calculation of a penalty may consider matters such as the seriousness and duration of the breach, consumer harm, cooperation and the need to achieve future deterrence.

4. Consumer Redress

Deterrence is not only about punishment. Consumer redress is also important.

If an electricity company has caused financial harm to consumers, regulatory enforcement can require payments or other forms of redress. This helps restore consumers and prevents the company from retaining the economic benefit associated with its unlawful conduct.

Therefore, electricity enforcement can combine:

penalty + consumer redress + corrective action + future compliance.

Ofgem specifically recognises fines and redress as separate but related enforcement outcomes.

5. Market Manipulation and Electricity Trading

Deterrence is particularly important in wholesale electricity markets. Electricity prices can change very quickly because supply and demand must remain balanced.

If a trader or generator deliberately manipulates bids, prices or available capacity, other market participants and consumers may be affected.

For example, Ofgem's enforcement action against EP SHB Limited resulted in a £23.63 million penalty concerning excessive bid prices during transmission-constraint periods. Ofgem stated that the conduct affected consumers through higher costs.

This demonstrates how a penalty can send a wider message to other market participants that strategic manipulation of electricity markets can result in serious consequences.

6. Case Law: ScottishPower v HMRC

In ScottishPower (SCPL) Ltd & Others v HMRC [2025] EWCA Civ 3, the Court of Appeal considered issues arising from penalties connected with Ofgem's regulatory enforcement.

The case is useful for understanding deterrence because the court discussed the regulatory objectives behind penalties, including achieving appropriate outcomes for consumers and deterring future non-compliance.

Its importance is that electricity penalties are not necessarily designed only to punish past behaviour. They can also be designed to influence future behaviour by the same company and other regulated businesses.

7. Enforcement Orders

Financial penalties are not the only enforcement mechanism. Regulators can use orders and directions requiring companies to change their behaviour.

This is particularly useful where continuing non-compliance could cause ongoing consumer or system harm.

For example, an enforcement order may require an electricity company to improve its procedures, provide information, change its practices or comply with a particular regulatory obligation.

This creates a more practical form of deterrence because the company must change the behaviour that caused the regulatory problem.

8. Deterrence and Electricity Network Security

Deterrence also applies to electricity infrastructure and cybersecurity.

Modern electricity networks depend heavily on digital systems, smart meters, control systems and communications networks. A cybersecurity failure can therefore have consequences beyond the individual company.

Ofgem's enforcement framework for the Network and Information Systems Regulations recognises enforcement as a means of encouraging compliance and deterring failures in the protection of critical energy systems.

9. Proportionality

Deterrence must be balanced with proportionality and fairness.

A regulator should consider:

seriousness of the breach;

duration of the conduct;

harm to consumers;

financial benefit obtained;

whether the company cooperated;

steps taken to correct the breach; and

whether stronger enforcement is necessary to deter future violations.

Therefore, deterrence does not mean automatically imposing the maximum penalty.

10. Limits of Deterrence

Deterrence-based enforcement also has weaknesses. If penalties are too low, large companies may simply treat them as a cost of doing business. Enforcement that takes too long may also reduce its preventive effect.

For this reason, electricity regulation needs a combination of monitoring, guidance, reporting duties, investigations, penalties, consumer redress and corrective orders.

11. Conclusion

Deterrence-based electricity enforcement uses regulatory consequences to make unlawful electricity-sector behaviour less attractive. Its purpose is broader than punishing one company: it seeks to influence the behaviour of the entire electricity market.

The strongest approach combines early detection, effective investigation, proportionate penalties, consumer redress and corrective measures. In this way, enforcement supports consumer protection, fair electricity markets, reliable networks and long-term regulatory compliance.
