A recent grid oscillation recorded in Rajasthan was reportedly felt as far as Kudankulam, Tamil Nadu, highlighting the growing stress within India’s national electricity grid. The incident has drawn attention to structural challenges in managing the rapid expansion of renewable energy while ensuring grid stability.

What are Grid Oscillations?

Grid oscillations refer to rapid fluctuations in voltage and frequency within the power transmission network. These fluctuations typically arise when there is a sudden mismatch between electricity generation and demand.

With increasing penetration of solar and wind energy, which are inherently variable and weather-dependent, the grid faces intermittent supply conditions. When not balanced properly, such variations can:

• Destabilise transmission voltage and frequency
• Damage equipment
• Trigger cascading failures
• Lead to large-scale blackouts

The recent oscillation event underscores the sensitivity of interconnected grids across long distances in India’s unified national grid.

Key Reasons for Grid Instability

• Limited Grid Flexibility and Automation: India’s grid is not yet sufficiently “smart” to seamlessly switch between conventional (coal-based) and renewable sources. Inadequate automation, limited real-time balancing mechanisms, and weak forecasting systems restrict efficient load management.
• Coal Plant Inflexibility: Coal-fired power plants are designed primarily for baseload supply, operating at steady output levels. They cannot ramp up or down rapidly to compensate for sudden drops or surges in renewable generation. This structural rigidity makes balancing intermittent sources difficult.
• Inadequate Energy Storage Infrastructure: Large-scale battery storage and pumped hydro facilities remain limited. Without sufficient storage:
  • Surplus renewable energy cannot be stored for later use.
  • Sudden drops in renewable output create supply gaps.
  • Grid stability becomes vulnerable during peak fluctuations.

India’s Renewable Energy Expansion

India has made significant strides in renewable energy capacity:

• 48 GW of renewable capacity was added in 2025, the highest-ever annual addition.
• Non-fossil sources now account for approximately 52% of installed capacity (around 264 GW).

However, a critical structural gap remains:

• Despite the large installed renewable capacity, nearly 75% of actual electricity generation still comes from coal because it provides reliable, on-demand power.

This highlights the distinction between installed capacity and actual generation share, an important concept for energy policy analysis.

Structural and Policy Implications

• Need for Smart Grid Modernisation: Deployment of advanced forecasting tools, AI-based load management, and automated switching systems is essential to manage renewable variability.
• Flexible Thermal Operations: Retrofitting coal plants for flexible operations can improve ramping capability and support renewable balancing.
• Energy Storage Expansion: Investment in:
  • Grid-scale battery storage
  • Pumped hydro storage
  • Green hydrogen-based storage is critical for long-term stability.
• Grid Infrastructure Strengthening: Transmission upgrades under initiatives like the Green Energy Corridors must be accelerated to integrate renewable-rich regions with demand centres.

The United States Department of Energy (DOE) has selected Standard Nuclear as the first company to establish a domestic supply chain for TRi-structural ISOtropic (TRISO) nuclear fuel, marking a major step toward reducing dependence on Russian uranium and advancing nuclear innovation. The initiative, part of DOE’s Fuel Line Pilot Program (2025), is designed to strengthen US energy security, promote private sector participation, and accelerate the deployment of advanced nuclear reactors.

Why TRISO Matters

TRISO is a next-generation nuclear fuel specifically engineered for high-temperature gas-cooled reactors (HTGRs) and molten salt-cooled reactors, both of which fall under Generation IV (Gen-IV) advanced reactor designs.

• Composition: TRISO fuel consists of a uranium–carbon–oxygen fuel kernel encapsulated by three protective layers of carbon and ceramic materials.
• Form: The particles are extremely small—seed-sized—and can be fabricated into cylindrical pellets or “pebbles.”
• Key Features:
  • Extreme durability: Resistant to neutron irradiation, corrosion, oxidation, and very high temperatures.
  • Self-containment: Each particle acts as its own containment system, preventing radiation leakage even under extreme reactor conditions.
  • Versatility: Compatible with multiple advanced reactor designs, including small modular reactors (SMRs).

This makes TRISO structurally and functionally superior to conventional nuclear fuels, ensuring safer, more reliable, and more efficient reactor performance.

Strategic Implications

• Energy Security & Supply Chains
  • The US has historically relied on imports of enriched uranium, particularly from Russia.
  • By developing domestic TRISO production in Tennessee and Idaho, the DOE seeks to build a resilient nuclear fuel ecosystem independent of geopolitical disruptions.
• Advanced Reactor Deployment
  • DOE’s Advanced Reactor Demonstration Program targets at least three new advanced reactor designs to achieve criticality by July 4, 2026.
  • TRISO fuel is central to this push, enabling safer operation of SMRs and Gen-IV reactors, both of which are crucial to America’s clean energy transition.
• Private–Public Partnership
  • Standard Nuclear will finance construction, operation, and decommissioning of TRISO fabrication facilities.
  • Reactor developers will source nuclear material feedstock, partly through DOE’s high-assay low-enriched uranium (HALEU) allocation program.
• Technological Momentum
  • Other firms, such as BWX Technologies (BWXT), have also developed TRISO production lines, including uranium nitride TRISO, in collaboration with Idaho and Oak Ridge National Laboratories.
  • These advancements reinforce US leadership in nuclear innovation while supporting its broader climate and national security goals.
