What You Need to Know
India has made significant strides in solar energy, with 157 Gw of solar capacity by May 2026, representing 29% of its total installed capacity. However, the integration of solar power into the grid poses challenges due to its intermittent nature. The 'duck curve' phenomenon, characterized by a sharp decline in net load during the day when solar power is abundant and a steep increase in the evening, necessitates the development of energy storage solutions.
Why It Matters for UPSC
The importance of energy storage lies in its ability to stabilize the grid and ensure a reliable power supply. Without adequate storage, the grid may struggle to absorb excess solar power during the day and meet the increased demand in the evening. This can lead to inefficiencies, increased costs, and strain on conventional generators. The article highlights that India's current storage capacity is insufficient, with only 0.27 Gw of batteries installed as of January 2026, despite a projected need of 8.68 Gw by 2026-27.
Current Relevance
The article emphasizes the need for India to develop its energy storage capabilities to support its growing solar energy sector. The government has taken steps to address this challenge, including drafting the Electricity (Amendment) Bill, 2025, which incorporates energy storage into the law for the first time. Additionally, the draft Electricity (Rights of Consumers) Amendment Rules, 2026, aim to introduce time-of-day tariffs and set firm deadlines for demand response. These measures are crucial for managing the grid effectively and ensuring a smooth transition to renewable energy sources.
Key Points for Revision
- •India has 157 Gw of solar capacity, representing 29% of its total installed capacity.
- •The 'duck curve' phenomenon poses challenges for grid management due to the intermittent nature of solar power.
