How Pumped Storage Power Can Transform Bihar’s Industrial Growth

Bihar has historically been the cradle of some of India’s greatest empires—from the Magadha Empire and Magadha Mahajanapada to periods under the Mughals, when provinces like Bihar, Bengal, and Odisha consistently contributed revenue to the central treasury. Over time, colonial policies and internal political challenges slowed development, leading to the label of “BIMARU state.” Changing this narrative requires focusing on industrial growth, which depends heavily on reliable power infrastructure.

For decades, coal-based power plants formed the backbone of Bihar’s energy supply. However, with stricter carbon emission targets and the push for sustainable energy, the state is gradually transitioning to renewable sources. The challenge with renewables, especially solar power, is intermittency—electricity generation depends on sunlight, making consistent supply difficult.

Pumped Storage Power: A Game-Changer

A major solution is pumped storage electricity, a form of renewable energy that stores surplus power for later use. In southern Bihar’s Nawada district, a historic region once central to the Magadha Empire, a 2,120 MW (2.1 GW) pumped storage project has been approved under Bihar’s Pumped Storage Project Promotion Policy 2025. With an investment of ₹13,000 crore, this represents the state’s largest renewable energy initiative to date and has the potential to become a cornerstone of Bihar’s industrial transformation.

How Pumped Storage Works

Pumped storage projects use the potential energy of water to stabilize power supply:

1. During peak solar generation, excess electricity pumps water from a lower reservoir to a higher reservoir.

2. When solar energy is unavailable, the water flows back down, turning turbines to generate electricity.

This closed-loop system requires no river dam, minimizing environmental impact and ensuring reliable energy supply, day or night.

Significance for Bihar

• Reliable electricity during peak industrial hours
• Strengthened energy security and grid stability
• Enhanced industrial growth and investment
• Reduced reliance on fossil fuels

Project Design Features

• Off-stream reservoirs: Independent of river flow, reducing ecological disruption
• Closed-loop circulation: Minimizes water wastage and social displacement

Investment Breakdown

• Genco Energies: ₹7,800 crore (Amba site)
• Sun Petrochemicals: ₹5,200 crore (Sahatri site)
• Location: Nawada district, Bihar

Challenges

• Land acquisition and rehabilitation
• Environmental and regulatory compliance
• Managing costs and timelines
• Ensuring local workforce participation and skill development

Addressing these challenges effectively can help Bihar retain talent and create a sustainable industrial ecosystem.

Bihar’s pumped storage project represents a strategic leap toward renewable energy and industrial development. Reliable power infrastructure, combined with investment in local talent and industries, can help rewrite Bihar’s developmental narrative, turning historical potential into modern progress.
