Why in the News?

Despite rising power deficits amid urbanisation and climate pressures, India’s UJALA scheme showcases energy efficiency’s impact—saving $10B and 9,500 MW—highlighting efficiency over mere capacity expansion.

What challenges does India face in meeting its peak power demand?

• Rising Peak Demand due to Urbanisation and Climate Change: Rapid urbanisation and increasing use of cooling appliances during hotter summers have significantly increased electricity demand. Eg: In 2023–24, India’s peak power demand reached 250 GW, making it the third-largest power consumer globally.
• Slow Expansion of Power Generation Capacity: Building new power plants, especially coal-based, is capital- and time-intensive, which cannot keep pace with rising demand. Eg: Despite efforts, power deficit widened from 0.69% in FY20 to about 5% in FY24, reflecting supply constraints.
• Integration Challenges with Renewable Energy: While renewables are growing, their intermittent nature and grid integration issues limit their effectiveness in meeting peak demand. Eg: Solar and wind power face supply variability, making it difficult to meet peak-hour requirements consistently.

Why is enhancing energy efficiency crucial for India’s energy future?

• Bridges the Gap Between Demand and Supply: India faces a widening peak power deficit (from 0.69% in FY20 to ~5% in FY24) despite increased generation. Eg: Energy efficiency helps reduce demand quickly—schemes like UJALA lowered peak demand by 1,500 MW, easing pressure on the grid.
• Delays the Need for New (Often Fossil-Based) Power Plants: Building new fossil-fuel-based power plants is time-consuming and costly. Eg: Efficiency measures like LED lighting under UJALA avoided building 19 new coal plants (9,500 MW)—cutting cost, time, and pollution.
• Supports Climate Goals and Reduces Emissions: India’s energy mix still depends 70% on coal, worsening climate and pollution. Eg: Energy efficiency improvements between 2000–2018 helped avoid 300 Mt of CO₂ emissions, according to the International Energy Agency.

Where can further energy efficiency mandates be applied in India?

• Buildings and Construction Sector: Residential and commercial buildings consume significant energy, especially for cooling and lighting. Eg: Mandating energy-efficient designs and green building codes (like ECBC) in urban housing projects can reduce long-term electricity use.
• Home Appliances: Many households still use inefficient devices that consume more electricity. Eg: Expanding BEE’s star-rating program to cover more appliances like fans, refrigerators, and ACs can push consumers toward efficient options.
• Micro, Small and Medium Enterprises (MSMEs): MSMEs often use outdated machinery that wastes energy. Eg: Energy audits and subsidized upgrades in sectors like textiles or ceramics can reduce energy costs and improve competitiveness.

Way forward:

• Invest in Grid Flexibility and Energy Storage: Promote battery storage, pumped hydro, and smart grid systems to manage peak loads and integrate renewable energy reliably.
• Strengthen Energy Efficiency Mandates: Enforce stricter efficiency norms for buildings, appliances, and MSMEs, backed by incentives, audits, and awareness campaigns.

Mains PYQ:

[UPSC 2016] “Give an account of the current status and the targets to be achieved pertaining to renewable energy sources in the country. Discuss in brief the importance of National Programme on Light Emitting diodes (LEDs).”

Linkage: Despite growth in electricity generation, including recent additions of renewable energy, India has faced peak power demand deficits. While adding new power production capacity takes time, especially for fossil fuels, focusing on energy efficiency is presented as the quickest and least expensive way to address rising power demand and climate change. This question is highly relevant as it specifically asks about renewable energy targets and the importance of the National Programme on LEDs.
