ENERGY GOVERNANCE OPERATES UNDER INHERENT UNCERTAINTY

1. Introduction

Energy governance operates under inherent uncertainty because governments, regulators, courts and energy companies must make long-term decisions without possessing complete knowledge about future electricity demand, fuel prices, technological development, climate change, infrastructure performance, investment costs or political conditions.

Energy infrastructure commonly operates for decades. A coal-fired power station, nuclear facility, transmission network, gas pipeline or renewable-energy project may have consequences extending far beyond the information available when the original decision is taken.

Therefore, energy law cannot assume that regulators possess perfect knowledge.

The basic problem can be expressed as:

Incomplete Information + Long-Term Investment + Changing Technology + Environmental Risk + Demand Uncertainty = Inherent Energy Governance Uncertainty

The legal challenge is consequently not to eliminate uncertainty, which is impossible, but to establish institutions capable of making lawful, rational, precautionary and adaptable decisions despite uncertainty.

2. Sources of Uncertainty in Energy Governance

Energy systems face several interconnected uncertainties.

Demand uncertainty concerns how much electricity society will require in future. Economic growth, population changes, industrialisation and energy efficiency can substantially change forecasts.

Technological uncertainty concerns future costs and performance of renewable energy, batteries, nuclear technology, hydrogen, smart grids and other technologies.

Financial uncertainty includes changing interest rates, construction costs, electricity tariffs and fuel prices.

Environmental uncertainty includes climate change, water scarcity, pollution and extreme weather.

Finally, institutional uncertainty arises from changes in legislation, regulatory structures, government policies and market design.

Energy regulators therefore govern systems in which future conditions cannot be predicted with absolute precision.

3. Uncertainty Does Not Remove the Duty to Decide

A government cannot ordinarily justify inactivity simply because scientific or economic information is uncertain.

Instead, uncertainty changes the quality of decision-making required.

Decision-makers should identify relevant risks, consider available evidence, compare reasonable alternatives and explain why a particular course has been selected.

This connects energy governance with the constitutional principles of rationality, legality and administrative justice.

Case Law: Earthlife Africa Johannesburg v Minister of Environmental Affairs (Thabametsi) (2017)

A major South African example is Earthlife Africa Johannesburg v Minister of Environmental Affairs and Others 2017 (2) All SA 519 (GP).

The case concerned environmental authorisation for the proposed Thabametsi coal-fired power station.

The High Court considered whether climate-change consequences had been adequately assessed before authorisation. The judgment recognised that climate change created risks concerning greenhouse-gas emissions, water availability and the long-term viability of the proposed power station.

The significance is important:

Future uncertainty does not justify ignoring future consequences.

Instead, where long-term energy infrastructure may generate serious environmental consequences, the decision-making process must meaningfully investigate those consequences.

4. Climate Uncertainty and Energy Infrastructure

Climate change creates a particularly difficult form of uncertainty because energy infrastructure both contributes to climate change and is vulnerable to its consequences.

For example:

Coal Generation → Greenhouse-Gas Emissions → Climate Change

but simultaneously:

Climate Change → Water Scarcity/Extreme Heat → Reduced Power-System Reliability

The Thabametsi litigation demonstrates this relationship. The proposed power station required significant quantities of water in an already water-stressed area. The Court noted that climate change could intensify water scarcity and therefore affect the power station's viability during its lifetime.

Energy governance must therefore assess not merely the immediate effects of infrastructure but also reasonably foreseeable long-term risks.

5. Precautionary Principle

One important legal response to uncertainty is the precautionary principle.

The principle broadly means that uncertainty regarding the precise extent of environmental harm should not automatically become a reason for postponing reasonable protective measures.

In energy governance, precaution can influence decisions concerning:

• nuclear safety;
• radioactive waste;
• coal pollution;
• offshore drilling;
• transmission infrastructure;
• climate impacts; and
• environmentally sensitive renewable-energy developments.

Precaution does not mean that every uncertain project must be prohibited. Instead, it requires uncertainty itself to become a relevant consideration within risk assessment.

6. Uncertainty and Rational Energy Planning

Energy planning involves forecasting future generation requirements. However, forecasts are inherently imperfect.

Governments therefore require adaptable planning frameworks rather than treating one prediction as permanently correct.

This issue can be connected with Earthlife Africa Johannesburg v Minister of Energy and Others 2017 (5) SA 227 (WCC) concerning South Africa's proposed nuclear procurement programme.

The case involved determinations for the procurement of approximately 9.6 GW of nuclear generation capacity and related governmental arrangements. The High Court ultimately declared the relevant nuclear procurement determinations unlawful and unconstitutional.

The judgment is significant for uncertainty because massive energy investments cannot escape constitutional and statutory governance merely because government considers them necessary for future energy security.

Long-term uncertainty actually strengthens the importance of transparent, rational and procedurally lawful decision-making.

7. Irreversibility and Energy Decisions

Another major problem is irreversibility.

Some energy decisions create commitments lasting several decades.

For example:

Decision Today → Construction → Financing → Infrastructure Lock-In → Long-Term Tariff and Environmental Consequences

Once billions have been invested in particular infrastructure, changing technological direction becomes economically difficult.

This creates the danger of technological lock-in.

Legal oversight is therefore especially important before governments undertake extremely expensive and long-lasting infrastructure commitments.

The nuclear procurement litigation illustrates this point. The High Court scrutinised governmental determinations and intergovernmental arrangements because the proposed programme involved major questions of procurement, energy security and constitutional legality.

8. Adaptive Energy Governance

Because uncertainty cannot be eliminated, energy governance should become adaptive.

Adaptive governance means institutions continuously revise decisions as new information becomes available.

The process can be represented as:

Forecast → Decision → Implementation → Monitoring → New Information → Regulatory Adjustment

This requires flexible licensing conditions, periodic energy-plan reviews, environmental monitoring, tariff reassessment and opportunities to reconsider obsolete assumptions.

Therefore, good energy regulation should distinguish between certainty and resilience.

A resilient regulatory system does not claim that its original predictions will always be correct. Instead, it possesses mechanisms capable of responding when those predictions prove incorrect.

9. Uncertainty and Judicial Review

Courts generally do not replace technically specialised energy regulators merely because another policy choice might have been possible.

However, uncertainty does not create a law-free zone.

Courts can examine whether decision-makers:

considered relevant information;
ignored material risks;
followed statutory procedures;
acted rationally;
provided required participation; and
complied with constitutional obligations.

This distinction is fundamental.

Courts need not determine the perfect energy policy. They ensure that uncertain energy choices are made through legally legitimate processes.

The Thabametsi case illustrates this approach because the court focused on whether climate consequences had been properly considered within the environmental authorisation process rather than designing South Africa's electricity mix itself.

10. Core Legal Principle

The central principle is:

Uncertainty does not reduce the need for energy regulation; it increases the need for rational, precautionary, transparent and adaptive regulation.

Energy authorities cannot know future demand, technologies, climate conditions or costs perfectly. But they can establish decision-making processes capable of responding intelligently to incomplete knowledge.

Thus:

Uncertainty → Risk Assessment → Precaution → Monitoring → Adaptation → Resilient Energy Governance

Conclusion

Energy governance inherently operates under uncertainty because energy decisions concern complex systems and long-term futures that cannot be predicted with complete accuracy. Electricity demand, technological innovation, climate change, fuel prices, water availability and infrastructure reliability continuously evolve.

Cases such as Earthlife Africa Johannesburg v Minister of Environmental Affairs (Thabametsi) demonstrate that uncertainty about future climate consequences does not permit authorities to disregard those consequences. Meanwhile, Earthlife Africa Johannesburg v Minister of Energy demonstrates the constitutional importance of lawful decision-making surrounding major long-term energy commitments such as nuclear procurement.

The appropriate legal response is therefore not to demand impossible certainty but to construct adaptive, evidence-based, transparent and precautionary governance systems. In this sense, the legitimacy of energy governance depends not upon accurately predicting every future event, but upon developing institutions capable of recognising uncertainty, managing risk, learning from new information and correcting decisions as circumstances change.
