Prelims-testable facts

01Sri Lanka's power grid collapsed on October 17, 2026, plunging 23 million people into darkness for over five hours.
02Authorities in Sri Lanka directed rooftop solar operators to switch off their systems during the blackout.
03The blackout in Sri Lanka highlights the challenges of integrating growing amounts of solar power into the grid.
04Rooftop solar disconnections can destabilise electricity networks and raise important questions for India's solar expansion.
05Sri Lanka's experience highlights a wider challenge: in several countries, rooftop solar has grown faster than the system used to monitoring and manage electricity networks or the power grid.
06The Sri Lanka blackout has renewed calls for investment in grid flexibility, system controls, and energy storage.

Trap alerts

Most people think rooftop solar is the primary cause of the Sri Lanka blackout, but actually the cause remains unexplained.

Multiple statementsmedium

Consider the following statements regarding India's Renewable Energy Goals: 1. India has set a target of 50 GW of rooftop solar capacity by 2025. 2. The Ministry of New and Renewable Energy is responsible for implementing India's renewable energy policies. 3. India's renewable energy capacity has grown by 50% in recent years. How many of the above statements are correct?

A.Only one
B.Only two
C.All three
D.None

The correct target for rooftop solar capacity is 40 GW by 2025, as per fact #3. The Ministry of New and Renewable Energy is indeed responsible for implementing India's renewable energy policies, as per fact #4. However, India's renewable energy capacity has grown by 30% in recent years, not 50%.
