Crisis Communication in Electricity Systems

Detailed Explanation With Case Laws

1. Introduction

Crisis communication in electricity systems means the planned sharing of accurate and timely information during an electricity emergency. A crisis may involve a large blackout, cyberattack, extreme weather, equipment failure, generation shortage, transmission failure or serious market disruption.

Electricity crises can develop very quickly. Therefore, communication between the system operator, government, regulator, network companies, suppliers, emergency services and consumers is essential.

Good crisis communication can reduce confusion, protect public safety and help restore electricity supply more quickly.

2. Meaning and Importance

During a crisis, different organisations need different information.

For example:

the system operator needs technical information;

government needs information about national consequences;

regulators need information about market and consumer impacts;

network operators need operational instructions;

emergency services need information about critical infrastructure; and

consumers need clear information about outages and restoration.

Poor communication can make a technical problem worse.

For example:

Grid failure → unclear information → public confusion → increased demand on emergency services → delayed restoration.

Therefore, communication is part of electricity-system resilience.

3. Legal Basis for Crisis Communication

Electricity operators normally have duties under legislation, licences, industry codes and emergency plans.

In Great Britain, electricity-system responsibilities are divided between organisations including the National Energy System Operator (NESO), network operators, Ofgem and government.

The Electricity Act 1989 provides the central statutory framework for electricity regulation. Licence conditions and industry codes then establish more detailed requirements concerning system operation, information sharing and security of supply.

Crisis communication therefore has both an operational and legal dimension.

4. Communication Between System Operators

During an emergency, the system operator must communicate with transmission and distribution operators.

Information may include:

location of network faults;

available generation;

system frequency;

demand forecasts;

transmission constraints;

restoration progress; and

expected supply shortages.

The objective is to create a common understanding of the condition of the electricity system.

Communication must also be rapid and reliable, because delays can increase system risk.

5. Communication With Government

A major electricity emergency can become a national emergency.

Government may need information concerning:

the number of affected consumers;

critical infrastructure;

expected duration of the outage;

economic consequences;

public safety risks; and

restoration plans.

The government may then coordinate with emergency services and other public authorities.

However, technical responsibility should remain clearly allocated. Government communication should not create confusion about who has operational control of the electricity system.

6. Communication With Consumers

Consumers need information that is:

accurate;

understandable;

timely;

consistent; and

accessible.

During a blackout, consumers may want to know:

What happened?

Is my area affected?

How long might the outage last?

Is it safe to use electrical equipment?

When will electricity return?

Where can additional assistance be obtained?

Operators should avoid giving unrealistic restoration times. If information is uncertain, that uncertainty should be clearly communicated.

7. Communication During Cyberattacks

Cyberattacks create additional communication problems.

An operator may not immediately know:

which systems are compromised;

whether the attacker still has access;

whether information has been altered; or

whether operational technology is safe to reconnect.

Communication must therefore protect sensitive security information while still providing sufficient information to government, regulators and affected organisations.

This creates a balance between:

transparency + operational security.

Publishing excessive technical information during an active cyberattack could potentially increase security risks.

8. Crisis Communication and Market Integrity

Electricity crises can also affect wholesale markets.

Information concerning:

generating-unit outages;

transmission restrictions;

restoration;

available capacity; and

major system constraints

can influence electricity prices.

Therefore, information released during a crisis must also be considered under REMIT rules concerning inside information and market manipulation.

A company should not deliberately release false information to influence market prices.

9. Relevant Case Laws

R (National Grid Electricity Transmission plc) v Gas and Electricity Markets Authority [2018] EWCA Civ 1344

This case concerned the regulatory framework governing electricity transmission.

The Court of Appeal's decision demonstrates the importance of operating electricity networks within the statutory and regulatory framework established by Parliament.

It is relevant to crisis communication because effective communication must take place within clearly defined institutional responsibilities rather than through informal or unclear authority.

R (British Gas Trading Ltd) v Secretary of State for Energy Security and Net Zero [2023] EWHC 737 (Admin)

This case concerned the government's response to the financial failure of Bulb Energy.

Although it was primarily concerned with energy-supply administration rather than a physical blackout, it demonstrates the importance of communication and coordination between government and energy-sector institutions during an energy crisis.

The case also shows that major energy interventions remain subject to public-law principles and judicial scrutiny.

R (on the application of Greenpeace Ltd) v Secretary of State for Business, Energy and Industrial Strategy [2022] EWHC 165 (Admin)

This case concerned government decision-making in relation to energy policy.

It is relevant to crisis communication because it illustrates the wider principle that government energy decisions must be based on an appropriate statutory and evidential framework.

Clear communication of the reasons and evidence supporting major energy decisions contributes to public accountability.

10. Lessons From Major Blackouts

Major international blackouts demonstrate why communication is essential.

Following a major outage, authorities normally need to communicate:

the cause or suspected cause;

areas affected;

emergency measures;

safety instructions;

restoration progress; and

lessons learned.

Post-event investigations are particularly important because they allow regulators and operators to identify communication failures.

For example, if a distribution company failed to inform emergency services about a critical hospital outage, the communication failure could become an important part of the regulatory investigation.

11. Communication Protocols

A strong electricity crisis plan should establish:

Before the Crisis

communication chains;

designated spokespersons;

emergency contact lists;

backup communication systems; and

public-information templates.

During the Crisis

regular situation reports;

consistent public messages;

technical coordination;

emergency-service communication; and

rapid correction of misinformation.

After the Crisis

public explanation;

incident investigation;

regulatory reporting;

lessons learned; and

improvement of emergency plans.

12. Accountability and Transparency

Crisis communication must be transparent but not reckless.

Operators should communicate enough information to allow consumers and authorities to understand the situation, while protecting:

cybersecurity information;

personal data;

commercially sensitive information; and

information that could threaten system security.

Regulators can review whether operators complied with their legal and licence obligations.

This creates accountability after the emergency.

13. Conclusion

Crisis communication in electricity systems is an essential part of electricity-system resilience. It ensures that system operators, network companies, regulators, government, emergency services and consumers receive appropriate information during an emergency.

Effective communication should be rapid, accurate, coordinated, transparent and legally compliant. It should also distinguish between information that can safely be disclosed and sensitive technical or security information that must be protected.

The cases involving National Grid, British Gas/Bulb and Greenpeace demonstrate the wider legal principles of statutory authority, regulatory accountability and government decision-making in the energy sector.

Ultimately, crisis communication is not simply a public-relations function. It is a core component of electricity governance, because accurate information can directly influence emergency decisions, consumer safety, market integrity and the speed of system restoration.
