SHANTHI: The Atomic Pivot:
Introduction
1.
In the history of
post-independence India’s energy statecraft, nuclear power has long occupied a
unique position. For over six decades, atomic energy remained a tightly guarded
state monopoly under the statutory framework of the Atomic Energy Act of 1962.
While this centralized approach established indigenous technological
self-reliance, it fell short of delivering the massive scale required to power
a rapidly expanding economy. Today, nuclear power accounts for less than 3% of
India's total installed electricity generation capacity.
2.
The enactment of the Sustainable
Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI)
Act, 2025, alongside its recently released draft SHANTI Rules, 2026,
represents a significant policy reform. By opening the civil nuclear domain to
private capital, foreign collaboration, and captive power generation, the state
aims to expand nuclear capacity to 100 Gigawatts (GW) by 2047.
3.
However, transitioning from
a state monopoly to a competitive market framework raises complex questions
regarding tariff predictability, risk allocation, capital financing, and
regulatory oversight.
Nuclear Energy in India: Current Status and
Strategic Value
1.
Nuclear energy provides a
vital, zero-emission baseload power source. Unlike solar and wind
energy—which are inherently intermittent and depend on weather
conditions—nuclear power plants operate at exceptionally high Plant Load
Factors (PLF) exceeding 80% with an operational design life of 60 years or
more.
2.
Beyond basic grid
stability, modern nuclear power—particularly Small Modular Reactors (SMRs)—is
increasingly viewed as an essential energy source for high-tech,
power-intensive industries. SMRs can provide dedicated, reliable captive power
for artificial intelligence data centres, semiconductor fabrication facilities,
supercomputing hubs, and green hydrogen production.
The SHANTI Act, 2025 and the Privatization of
Nuclear Energy
The SHANTI
Act, 2025 (which replaced the legacy Atomic Energy Act, 1962, and the Civil
Liability for Nuclear Damage Act, 2010) established an updated legal framework
for atomic power:
1.
Private Sector
Participation: Permits private and foreign joint ventures
to build, own, and operate civilian nuclear installations under regulated
oversight.
2.
Single Composite Licence: Introduces a streamlined licensing process through the draft SHANTI
Rules, 2026, covering site selection, construction, operation, and eventual
decommissioning under a single regulatory umbrella.
3.
Strengthening Regulatory
Independence: Grants statutory backing to the Atomic
Energy Regulatory Board (AERB), empowering it with independent enforcement,
inspection, and safety mandate.
4.
No-Fault Operator
Liability: Establishes a strict, no-fault liability
regime for plant operators alongside mandatory long-term financial security and
insurance requirements.
The Dual Challenge: Investment and Tariff
Structures
While the
legislative path for private entry is clear, commercial viability remains a
major hurdle. Industry experts and distribution companies (discoms) have
highlighted several structural challenges:
1.
High Upfront Capital and
Gestation Costs: Nuclear installations require massive
initial capital expenditure and long construction periods (typically 6 to 8
years). Traditional short-term project financing strains cash flows during
construction. Developers are calling for long-term green bond financing and
back-ended tariff structures.
2.
Cost Asymmetries Across
Technologies: Indigenous Pressurised Heavy Water Reactors
(PHWRs) operated by NPCIL generate electricity at around ₹4 per unit. In
contrast, imported foreign technology or unproven SMR designs are substantially
more expensive.
3.
Tariff Fixation vs. Bidding
Mechanisms: Unlike solar and wind power—where tariffs
are determined through competitive market bidding—nuclear tariffs under the
SHANTI Act are established by the Department of Atomic Energy (DAE) based on
committee recommendations.
4.
The Single-Part vs.
Two-Part Tariff Conflict: Currently, nuclear power
operates on a single-part tariff as a baseload supply. However, state
distribution companies (discoms) are advocating for a two-part tariff
structure (separating fixed capacity charges from variable fuel charges).
This would allow discoms the flexibility to ramp nuclear supply down or up as
variable renewable power (solar/wind) fluctuates on the grid, without
penalizing the plant operator financially.
Core Issues for Policy Consideration
1.
Establishing a Level
Playing Field: Nuclear equipment currently faces higher
Goods and Services Tax (GST) rates (18%) compared to competing renewable
technologies (5%). Furthermore, nuclear energy requires formal classification
as "Green Energy" to unlock global ESG capital pools and green bonds.
2.
Viability Gap Funding (VGF)
for SMRs: Early-stage SMR deployments carry higher
per-megawatt costs. Without initial government capital support or VGF
mechanisms, private developers may hesitate to deploy SMR technology at scale.
3.
Managing Construction Cost
Overruns: Historical nuclear projects have often
experienced prolonged delays, driving up interest costs during construction.
Clear contractual risk allocation between developers, vendors, and discoms is
necessary to protect consumers from sudden tariff hikes.
Way Forward
To build
a predictable, bankable nuclear energy ecosystem by 2035, policymakers should
focus on four priorities:
1.
Transparent Regulatory
Tariff Guidelines: DAE must establish a
clear, long-term regulatory tariff methodology that outlines benchmark fuel
costs, foreign exchange adjustments, and capital expenditure approvals.
2.
Mitigating Merchant Risk: The Centre should consider providing guaranteed minimum floor tariffs
or power purchase assurance frameworks to safeguard private developers against
extreme market price collapses.
3.
Accelerating
Indigenization: Lowering reliance on imported components and
scaling domestic manufacturing capacity will be essential to bringing capital
costs down toward the competitive ₹8/kWh target.
4.
Operationalizing National
Risk Pools: Developing accessible nuclear liability
insurance structures under the draft SHANTI Rules, 2026, will help private
operators secure financial backing without bearing unmanageable liability
risks.
Conclusion
The
SHANTI Act, 2025, marks a major step in modernizing India's nuclear governance.
By combining private sector agility with strict safety oversight by the AERB,
India has created a legal framework capable of supporting its long-term energy
needs. However, turning this legal framework into operational reactors will
depend on establishing transparent, predictable, and fair tariff rules.
Balancing fair returns for private investors with affordable electricity for
consumers will allow nuclear energy to serve as a reliable, clean foundation
for India's net-zero transition.
