1. Introduction

The integration of biodiversity law into energy infrastructure means incorporating the protection of species, habitats, ecosystems and ecological processes into the planning, approval, construction, operation and decommissioning of energy projects.

Energy infrastructure—including solar parks, wind farms, hydroelectric projects, transmission lines, substations, pipelines, thermal power plants, offshore wind facilities and energy-storage systems—can produce significant environmental benefits in the context of decarbonisation, but can also create biodiversity impacts. These may include habitat fragmentation, bird and bat mortality, forest diversion, disturbance of marine ecosystems, loss of wetlands and impacts on protected species.

Modern environmental law therefore increasingly requires energy infrastructure to be planned not merely according to engineering and economic criteria, but through environmental impact assessment, ecological screening, protected-area regulation, species protection, mitigation, restoration and monitoring.

In India, this integration operates through the Environment (Protection) Act 1986, Environmental Impact Assessment Notification 2006, Wild Life (Protection) Act 1972, Forest (Conservation) Act 1980 as amended, Biological Diversity Act 2002 as amended in 2023, and related rules and regulations. The Supreme Court's environmental jurisprudence has also established principles such as sustainable development, precaution, public trust and scientifically informed environmental decision-making. The Supreme Court itself categorises energy laws and environmental laws separately but overlappingly, including environmental clearance and biodiversity legislation. (Supreme Court of India)

2. Meaning of Biodiversity Law in the Energy Sector

Biodiversity law concerns the conservation and sustainable use of:

Genetic diversity

Species diversity

Ecosystem diversity

Habitats of threatened species

Protected areas

Ecologically sensitive areas

Wetlands, forests, grasslands and coastal ecosystems

When applied to energy infrastructure, biodiversity law asks questions such as:

Where should the project be located?

Will construction destroy or fragment habitat?

Will transmission lines cause bird collisions?

Will turbines affect protected birds or bats?

Will hydropower alter river ecosystems?

Will offshore wind affect marine species?

Is forest or wildlife-land diversion legally permissible?

Are alternatives available that cause less ecological damage?

Can impacts be avoided, minimised, restored or compensated?

Thus, biodiversity law should operate before project approval, rather than being treated merely as a condition imposed after construction has been authorised.

3. Major Legal Mechanisms

A. Environmental Impact Assessment

Environmental Impact Assessment (EIA) is one of the principal mechanisms through which biodiversity considerations enter infrastructure planning.

An energy project requiring environmental clearance must assess relevant environmental consequences. Biodiversity-related information may include:

flora and fauna surveys;

endangered species;

wildlife corridors;

habitat fragmentation;

forest cover;

wetlands;

aquatic ecosystems;

migratory routes;

cumulative impacts; and

proposed mitigation measures.

The Supreme Court has emphasised that environmental decision-making must be based on adequate empirical information. In Hanuman Laxman Aroskar v Union of India, the Court scrutinised the environmental-clearance process and emphasised the importance of a genuine, informed and legally compliant decision-making process.

The broader principle was reiterated in subsequent environmental litigation: environmental assessment should not be regarded simply as an obstacle to infrastructure development but as a mechanism for making an informed decision consistent with sustainable development and precaution. (Sci API)

Application to energy infrastructure

For example, before approving a large solar or wind project, authorities may need to consider:

Project location → habitat → species → ecological impacts → alternatives → mitigation → residual impacts → monitoring.

This transforms biodiversity from an external consideration into part of the infrastructure approval process.

4. Wildlife Protection and Energy Infrastructure

The Wild Life (Protection) Act 1972 becomes particularly important where energy infrastructure affects:

national parks;

wildlife sanctuaries;

conservation reserves;

protected species;

ecological corridors; or

areas surrounding protected areas.

Transmission lines, roads, mines supplying power stations and renewable-energy projects may interact with protected landscapes.

The Supreme Court has repeatedly insisted that wildlife-related approvals cannot simply be ignored during infrastructure development.

Goa Foundation v Sesa Sterlite Ltd (2018)

In Goa Foundation v Sesa Sterlite Ltd., the Supreme Court considered environmental clearances and compliance with wildlife-protection requirements. The Court's discussion highlighted serious failures involving environmental clearances and the requirement for approval of the Standing Committee of the National Board for Wildlife in relevant circumstances. (Sci API)

The case demonstrates an important legal proposition:

Environmental clearance does not automatically substitute for separate statutory wildlife protections.

For energy infrastructure, this means that a developer may need to satisfy multiple environmental regimes rather than treating a single clearance as an all-purpose authorisation.

5. Forest Biodiversity and Energy Infrastructure

Energy infrastructure frequently requires land.

Transmission corridors, hydropower projects, mining projects, roads and renewable-energy developments can require the diversion of forest land.

The forest-conservation framework therefore creates an important biodiversity control.

T.N. Godavarman Thirumulpad v Union of India

The Godavarman litigation fundamentally changed Indian forest jurisprudence by requiring protection of forests according to their ecological character rather than relying exclusively on formal governmental classification.

The Supreme Court has continued to refer to the importance of identifying forest areas and regulating non-forest activities. In later proceedings, the Court reiterated the significance of prior Central Government approval for non-forest activity within forest areas. (Sci API)

Significance for energy infrastructure

An electricity transmission line or renewable-energy project cannot be assessed solely as an energy project where its physical footprint affects forest ecosystems.

The legal question becomes:

Can the infrastructure be designed, relocated or technologically modified to reduce forest loss?

This encourages:

route optimisation;

avoidance of intact forests;

reduced-width corridors where legally and technically feasible;

compensatory measures;

habitat restoration; and

monitoring of ecological impacts.

6. Biodiversity and Transmission Lines: The Great Indian Bustard Case

One of the clearest examples of biodiversity law interacting directly with energy infrastructure is M.K. Ranjitsinh v Union of India, concerning the critically endangered Great Indian Bustard (GIB) and overhead power transmission lines in Rajasthan and Gujarat.

The Court considered the conflict between:

conservation of the Great Indian Bustard; and

India's development of renewable-energy transmission infrastructure.

The Court initially imposed significant directions concerning overhead transmission lines, but subsequently recognised that a blanket requirement to underground all relevant transmission lines over an enormous area was not technically or economically practicable and would not by itself address all causes of GIB decline.

The 2024 judgment specifically noted other factors including habitat loss, fragmentation, predators, prey loss and the species' low fecundity. (Sci API)

The Court therefore moved toward a more scientifically informed and geographically differentiated approach.

It also required consideration of:

conservation and protection measures;

habitat restoration;

community engagement;

climate-change impacts;

sustainable future power-line options;

stakeholder participation; and

monitoring and research. (Sci API)

Legal significance

This case illustrates that biodiversity law does not necessarily require "energy infrastructure versus conservation" as an absolute choice.

Instead, law can require:

Energy transition + species conservation + technological alternatives + scientific assessment + adaptive management.

It is particularly significant because renewable-energy infrastructure itself can generate biodiversity conflicts.

7. The Precautionary Principle

The precautionary principle is central to biodiversity-sensitive infrastructure regulation.

Its basic logic is that lack of complete scientific certainty should not automatically justify proceeding with an activity where there is a credible risk of serious environmental damage.

In energy projects, this is relevant where scientific evidence concerning:

bird mortality;

marine ecosystems;

groundwater;

forest fragmentation;

endangered species;

cumulative impacts

is incomplete.

The precautionary principle does not necessarily prohibit development. Rather, it encourages decision-makers to incorporate uncertainty into project design and approval.

8. Sustainable Development

Indian environmental jurisprudence treats sustainable development as an important principle for reconciling development and environmental protection.

Energy infrastructure is a classic example.

A country needs:

electricity;

energy security;

industrial development;

electrification;

renewable energy;

grid expansion.

At the same time, it must protect:

forests;

wildlife;

biodiversity;

water systems;

ecological communities.

Therefore, sustainable development requires the infrastructure system to internalise ecological constraints.

The Supreme Court has repeatedly linked environmental decision-making with sustainable development and precautionary principles. (Sci API)

9. Public Trust Doctrine

The public trust doctrine treats important natural resources as resources that the State holds in trust for the public and future generations.

This is particularly relevant where energy infrastructure affects:

forests;

rivers;

wetlands;

coastal ecosystems;

wildlife habitat; and

common natural resources.

The doctrine prevents environmental resources from being treated simply as disposable inputs into infrastructure development.

In practical terms, government authorities must exercise their regulatory powers consistently with their environmental responsibilities.

10. Biological Diversity Act and Energy Projects

The Biological Diversity Act 2002, substantially amended in 2023, creates a legal framework for conservation, sustainable use and benefit-sharing.

Its importance for energy infrastructure is broader than simply protecting individual endangered species.

It can become relevant where projects interact with:

biological resources;

traditional knowledge;

local biodiversity;

biodiversity management committees;

access to biological resources; and

benefit-sharing mechanisms.

For large infrastructure projects, biodiversity governance can therefore involve not only central environmental authorities but also state and local institutional structures.

11. Biodiversity in Renewable-Energy Planning

Renewable energy is central to climate policy, but "renewable" does not automatically mean "biodiversity neutral."

Solar energy

Potential impacts include:

conversion of grasslands;

habitat fragmentation;

fencing;

disruption of animal movement;

water consumption for cleaning panels;

impacts on soil and vegetation.

Wind energy

Potential impacts include:

bird collision;

bat mortality;

habitat disturbance;

road construction;

transmission infrastructure.

Hydropower

Potential impacts include:

alteration of river flows;

fish migration barriers;

sediment disruption;

forest submergence;

fragmentation of aquatic ecosystems.

Offshore wind

Potential impacts can include:

seabed disturbance;

marine mammals;

birds;

fisheries;

underwater noise;

benthic ecosystems.

The UK Supreme Court's recent Orsted West of Duddon Sands litigation illustrates how environmental surveys form an important part of offshore-wind development. The Court's description of the development process specifically includes studies concerning seabed flora and fauna, construction timing and environmental effects. (Supreme Court of the United Kingdom)

12. Cumulative Impact Assessment

Traditional project assessment often asks:

"What will this particular project do?"

Biodiversity law increasingly requires a broader question:

"What happens when this project is added to everything else already affecting the ecosystem?"

This is particularly important for:

multiple wind farms;

large solar parks;

transmission corridors;

hydropower cascades;

offshore wind clusters;

mining-energy complexes.

A species may survive the impact of one project but not the cumulative effects of twenty projects.

Therefore, biodiversity-sensitive energy planning should consider:

individual impact + cumulative impact + landscape-level impact + long-term ecological change.

13. European Union Jurisprudence

European Union biodiversity law provides particularly developed examples through the Habitats Directive and Birds Directive.

Holohan and Others v An Bord Pleanála (C-461/17)

The Court of Justice of the European Union addressed the scope of appropriate assessment under Article 6(3) of the Habitats Directive.

The underlying principle is that projects capable of significantly affecting protected sites must undergo an appropriate assessment before authorisation.

This approach is relevant to energy infrastructure because wind farms, transmission systems and other projects may be located close to Natura 2000 sites.

Recent Irish wind-farm litigation

The CJEU has also recently considered Irish wind-farm projects and the requirement for appropriate assessment under Article 6(3), including situations where site-specific conservation objectives had not yet been established. (Court of Justice of the European Union)

This illustrates a sophisticated principle:

Energy infrastructure cannot avoid biodiversity assessment merely because the ecological regulatory framework is administratively incomplete.

14. UK Approach

UK environmental law also demonstrates the integration of biodiversity assessment with infrastructure planning.

In R (Finch) v Surrey County Council, the Supreme Court considered the scope of environmental assessment and the relationship between a project and environmental effects associated with its operation. The judgment discussed earlier Irish jurisprudence concerning the inclusion of indirect effects and infrastructure that is fundamentally connected with a project. (Supreme Court of the United Kingdom)

This is important for energy infrastructure because a project should not necessarily be artificially divided into isolated components when their environmental effects are functionally connected.

For example:

power plant + fuel supply + transmission connection

may need to be considered in an integrated environmental framework where the law requires assessment of connected or indirect effects.

15. Mitigation Hierarchy

A strong biodiversity-infrastructure framework normally follows the mitigation hierarchy:

1. Avoid

Choose a different location or route.

2. Minimise

Reduce the project's ecological footprint.

3. Restore

Repair damaged ecosystems after construction.

4. Compensate/offset

Address residual biodiversity impacts where legally permissible.

The hierarchy is important because financial compensation should not become an automatic substitute for avoiding destruction of irreplaceable habitat.

16. Biodiversity as a Design Requirement

The most effective integration occurs when biodiversity considerations are introduced during project design, rather than after the design has already been finalised.

For example:

Thus, biodiversity law can operate as a design constraint, not simply as a licensing requirement.

17. Institutional Integration

Effective implementation requires coordination among:

energy ministries;

electricity regulators;

environmental ministries;

forest departments;

wildlife authorities;

biodiversity authorities;

local governments;

electricity transmission companies;

project developers;

scientific institutions;

local communities.

Fragmented regulation can produce contradictory decisions—for example, an energy authority may approve a transmission route while a wildlife authority identifies the same area as ecologically sensitive.

Integrated planning reduces such conflicts.

18. Case-Law Principles at a Glance

The Indian cases are particularly significant because the Supreme Court's environmental jurisprudence treats environmental protection as a substantive component of lawful governance rather than merely a technical administrative formality. (Sci API)

19. Emerging Concept: Biodiversity-Sensitive Energy Transition

The traditional energy-transition model is:

Fossil fuels → Renewable energy

A more legally sophisticated model is:

Fossil fuels → Renewable energy + biodiversity protection + ecological restoration + climate resilience

This matters because poorly located renewable infrastructure can create new ecological pressures.

The Great Indian Bustard litigation is particularly illustrative: the Court recognised both India's renewable-energy objectives and the need to protect a critically endangered species, while seeking technically feasible and scientifically informed solutions rather than treating either objective in isolation. (Sci API)

20. Conclusion

Integration of biodiversity law into energy infrastructure represents a shift from project-by-project environmental regulation toward ecologically informed infrastructure governance.

The central legal principles are:

Prior environmental assessment

Wildlife and habitat protection

Forest conservation

Precautionary principle

Sustainable development

Public trust doctrine

Scientific decision-making

Cumulative-impact assessment

Mitigation hierarchy

Adaptive monitoring

Public and stakeholder participation

Integration of biodiversity into infrastructure design

Indian jurisprudence demonstrates that energy development cannot be evaluated exclusively through the lens of electricity generation, economic development or energy security. At the same time, biodiversity protection need not imply an absolute prohibition on infrastructure. The emerging legal approach is one of integration: infrastructure must be planned and technologically adapted so that energy, climate and biodiversity objectives can be considered together.

The M.K. Ranjitsinh litigation is especially important in this respect because it demonstrates the legal challenge of reconciling renewable-energy expansion with species conservation and shows why future energy planning must incorporate ecological data, alternative technologies, spatial planning and adaptive management from the beginning.
