Phase IFoundation

Background

Overview

Crucial for India's energy security, climate change mitigation goals (NDC targets), economic growth, and sustainable development. It involves a complex interplay of technology, policy, economics, and infrastructure, making it a multi-dimensional topic for UPSC.

India's rapid expansion of renewable energy, particularly solar and wind, necessitates robust grid integration strategies to manage intermittency and ensure stable power supply. This involves technological advancements, policy frameworks, and infrastructure development to balance generation and demand across the national grid.

  • India's RE capacity: Solar (154 GW), Wind (52 GW) by 2026.
  • Key challenge: Intermittency of solar, leading to grid instability.
  • Solution: Energy Storage Systems (BESS, PSP) and wind-solar hybridisation.
  • Policy shift: From 'capacity-first' to 'stability-first' integrated power model.
  • Institutions: MNRE, CEA, SECI, MoP drive policy and implementation.

Elimination traps

Authority vs ministryDistinguishing the roles of statutory bodies like CEA from ministries like MNRE or MoP in energy policy and implementation.

Ministry sets policy; regulator often has quasi-judicial powers.
