Which of the following authorities or provisions is empowered to invoke Section 11 of the Electricity Act, 2003, for mandating generation from captive coal-based power plants during peak demand?

Option C is correct because the Union Ministry of Power is the designated authority that invokes Section 11 of the Electricity Act, 2003, directing captive coal-based power plants above a specified capacity to generate electricity at maximum availability. MoEFCC deals with environmental clearances, not power sector emergency dispatches; RBI and NABARD deal with financial and agricultural credit matters.
