1. Introduction

Governance of unknown risks in energy systems refers to the legal, institutional and regulatory mechanisms used to manage threats whose probability, magnitude, timing or consequences cannot be reliably predicted in advance. It is different from ordinary risk management because conventional risks can generally be identified and assigned probabilities, whereas unknown risks involve deep uncertainty, incomplete scientific knowledge, emerging technologies or unforeseen interactions between systems.

Energy systems are particularly exposed to such risks because they involve interconnected electricity grids, oil and gas infrastructure, nuclear facilities, renewable-energy technologies, storage systems, digital control systems, artificial intelligence, climate-dependent generation and international supply chains.

The central governance question is therefore not merely “How can a known risk be controlled?”, but also “How should the law act when the nature of the risk itself is uncertain?”

Indian environmental and energy jurisprudence provides important foundations for this approach, particularly through the precautionary principle, sustainable development, public trust doctrine, absolute liability and adaptive regulatory powers.

2. Meaning of Unknown Risks

An unknown risk exists where decision-makers lack sufficient information to determine:

the probability of an event;

the extent of potential damage;

the interaction between different risks;

whether existing safety standards remain adequate;

the long-term consequences of a technology; or

whether a new technological or environmental phenomenon may create entirely new hazards.

For example, a regulator may understand the ordinary failure probability of a transformer but may not know the consequences of a highly interconnected grid failure involving artificial intelligence, battery storage, cyber systems and extreme weather simultaneously.

Thus:

Known risk → probability can reasonably be estimated.

Unknown risk → probability or consequences cannot reliably be estimated.

Governance response → precaution, resilience, monitoring, adaptability and continuous reassessment.

3. Sources of Unknown Risks in Energy Systems

A. Technological uncertainty

New technologies such as:

advanced batteries;

hydrogen;

carbon capture;

artificial intelligence;

autonomous grid management;

small modular reactors;

floating offshore wind; and

advanced geothermal systems

may create risks that existing regulatory frameworks were not designed to address.

B. Climate-related uncertainty

Extreme heat, floods, droughts, storms and changing rainfall patterns can affect:

thermal power plants;

hydropower;

transmission lines;

fuel transportation;

cooling-water availability; and

renewable-energy generation.

C. Systemic risks

Modern energy infrastructure is highly interconnected. Failure in one component can spread across:

generation → transmission → distribution → communications → financial markets → essential services.

Consequently, regulators must consider cascading failures rather than isolated accidents.

D. Geopolitical and supply-chain uncertainty

Energy systems depend upon international supplies of:

oil and gas;

coal;

uranium;

critical minerals;

semiconductor components;

batteries; and

renewable-energy equipment.

Unexpected export restrictions, wars or trade measures can therefore create energy-security risks.

E. Regulatory uncertainty

Frequent changes in:

tariffs;

environmental standards;

subsidies;

renewable obligations;

carbon policies; and

market rules

can create investment uncertainty and affect long-term infrastructure decisions.

4. Constitutional Foundation

Governance of unknown risks is closely connected with the Indian Constitution.

Article 21

The right to life has been interpreted broadly to include environmental protection and protection against serious environmental harm.

Article 14

Regulatory decisions concerning uncertain risks must be non-arbitrary, rational and based on relevant evidence.

Article 48A

The State is constitutionally directed to protect and improve the environment.

Article 51A(g)

Citizens have a fundamental duty to protect the natural environment.

Article 39(b)

Material resources of the community should be distributed to promote the common good.

Together, these provisions support a governance model in which energy development cannot be separated from environmental protection, public safety and intergenerational interests.

5. Precautionary Principle

The most important legal principle for unknown risks is the precautionary principle.

In Vellore Citizens' Welfare Forum v. Union of India, (1996) 5 SCC 647, the Supreme Court held that environmental authorities must anticipate and prevent environmental degradation and that scientific uncertainty cannot itself justify postponing protective measures where serious or irreversible damage is threatened. The Court expressly accepted the precautionary principle as part of Indian environmental law. (Indian Kanoon)

This principle is extremely important for energy governance.

For example, if a new energy technology has uncertain but potentially catastrophic environmental consequences, the regulator need not wait for an actual disaster before imposing safeguards.

Precaution may involve:

pilot projects;

safety standards;

environmental impact assessment;

monitoring;

emergency plans;

insurance requirements;

financial guarantees;

technology-specific licensing; and

periodic regulatory review.

6. Absolute Liability and Unknown Energy Hazards

Energy industries may involve inherently dangerous activities involving:

petroleum;

natural gas;

chemicals;

nuclear materials;

hazardous waste; and

high-voltage infrastructure.

In M.C. Mehta v. Union of India (Oleum Gas Leak Case), the Supreme Court developed the principle of absolute and non-delegable liability for enterprises engaged in hazardous or inherently dangerous activities. The enterprise must bear responsibility for harm resulting from such activity, even where it claims to have exercised reasonable care. (Indian Kanoon)

This is highly relevant to unknown risks because an enterprise cannot simply argue:

“The particular hazard could not have been predicted.”

The governance philosophy is that those who undertake hazardous activities must internalize the consequences of those activities and maintain the highest safety standards.

7. Polluter Pays Principle

Unknown risks also require appropriate financial responsibility.

Under the polluter pays principle, the entity responsible for environmental harm may be required not merely to compensate victims but also to bear the cost of ecological restoration.

Vellore Citizens' Welfare Forum recognized this principle as part of Indian environmental law. (Indian Kanoon)

In energy governance, this can justify:

environmental compensation;

restoration funds;

decommissioning funds;

financial guarantees;

insurance requirements;

remediation obligations; and

liability mechanisms.

8. Adaptive Governance

Unknown risks cannot be managed through completely rigid legislation.

The regulatory system must permit:

continuous data collection;

periodic review;

modification of technical standards;

emergency intervention;

expert consultation;

regulatory experimentation;

stakeholder participation; and

revision of outdated rules.

This principle is strongly supported by PTC India Ltd. v. CERC, (2010) 4 SCC 603. The Supreme Court explained that under the Electricity Act, CERC possesses important regulation-making and decision-making functions and that regulations constitute delegated legislation within the statutory framework. (Indian Kanoon)

This gives electricity regulators the institutional capacity to respond to changing market and technological conditions rather than relying exclusively on primary legislation.

9. Governance Through Scenario Planning

Where future conditions cannot be predicted, regulators should use scenario-based governance.

Energy authorities can develop scenarios involving:

extreme weather;

sudden fuel shortages;

major grid failure;

rapid renewable penetration;

battery-storage failure;

cyber incidents;

geopolitical disruption;

unexpected technology failure; and

simultaneous multiple crises.

The objective is not to predict exactly what will happen but to ensure that the energy system remains functional under several plausible futures.

10. Resilience and Redundancy

Unknown risks require energy systems to possess resilience.

Important measures include:

diversified generation;

multiple fuel sources;

reserve capacity;

geographically distributed infrastructure;

grid interconnections;

energy storage;

emergency electricity procurement;

backup communication systems;

black-start capability; and

disaster-recovery mechanisms.

A resilient system does not assume that failures can always be prevented. Instead, it ensures that failures do not become systemic catastrophes.

11. Regulatory Monitoring and Data Governance

Unknown risks frequently become visible only through accumulated information.

Therefore regulators should establish:

real-time monitoring;

incident reporting;

safety databases;

predictive analytics;

grid-condition monitoring;

environmental monitoring;

technology-performance databases; and

mandatory disclosure of significant failures.

CERC's statutory functions include regulating inter-State transmission, specifying the Grid Code, and enforcing standards concerning quality, continuity and reliability of electricity services. (CERC)

This monitoring function is essential for discovering previously unknown risks.

12. Contractual Governance of Unknown Risks

Long-term energy contracts also need mechanisms for unforeseen events.

Energy Watchdog v. CERC, (2017) is particularly important. The case concerned long-term PPAs and major changes affecting imported coal prices. The Supreme Court examined contractual provisions concerning force majeure and change in law, demonstrating that unforeseen market and regulatory developments do not automatically rewrite contractual obligations; their treatment depends upon the contractual and statutory framework. (Indian Kanoon)

The case illustrates an important governance lesson:

Unknown economic conditions should be allocated through carefully drafted contractual risk mechanisms rather than assumed to be automatically recoverable from consumers.

13. Public Trust and Intergenerational Governance

Unknown risks may affect future generations in ways that present decision-makers cannot accurately quantify.

The public trust doctrine therefore requires the State to manage important natural resources for present and future generations.

This is particularly relevant to:

fossil-fuel extraction;

groundwater-dependent energy projects;

forests and hydropower;

coastal energy infrastructure;

critical minerals; and

nuclear materials.

Energy governance must therefore consider long-term ecological and social consequences, not merely short-term energy supply.

14. Important Case Laws

15. Major Challenges

Governance of unknown risks faces several difficulties:

1. Lack of scientific information

Regulators may have to make decisions before adequate evidence becomes available.

2. Regulatory lag

Technology can develop faster than legislation.

3. Institutional fragmentation

Energy, environment, climate, disaster management and competition authorities may operate under different mandates.

4. Excessive precaution

Over-regulation can prevent beneficial innovation.

5. Insufficient precaution

Under-regulation may expose society to catastrophic consequences.

6. Intergenerational uncertainty

Some energy decisions have consequences lasting decades or centuries.

7. Liability uncertainty

It may be difficult to identify responsibility when multiple infrastructure operators contribute to a systemic failure.

16. Conclusion

Governance of unknown risks in energy systems requires a shift from prediction-based regulation to precautionary and adaptive governance.

The objective is not to eliminate every uncertainty—an impossible task—but to create institutions capable of detecting emerging risks, responding rapidly, learning from failures and revising regulatory frameworks.

Indian jurisprudence provides a strong foundation. Vellore establishes precautionary governance; M.C. Mehta establishes strong liability for hazardous activities; PTC India recognizes the regulatory capacity of electricity institutions; and Energy Watchdog demonstrates the importance of contractual allocation of unforeseen risks.

The ideal energy-governance framework therefore combines precaution, resilience, scientific expertise, transparency, monitoring, adaptive regulation, financial responsibility and intergenerational equity. In an energy system characterized by technological disruption, climate change and systemic interdependence, the ability to govern what is not yet fully known is becoming as important as the ability to regulate known risks.
