With reference to "Energy Banking," consider the following:1.It allows a renewable energy generator to "deposit" surplus power into the grid and "withdraw" it later.2.Banking is typically allowed on a monthly or yearly basis as per State Electricity Regulatory Commission (SERC) norms.3.The grid owner usually charges a "banking fee" in the form of a percentage of the energy stored.Which of the statements given above is/are correct?

Correct Answer: C - 1, 2 and 3

Quick Concept Explanation

Energy banking is a regulatory arrangement in which eligible renewable generation exported at one time can be adjusted or withdrawn against consumption in another permitted period. The settlement period, banking charge/loss and eligibility are set by the applicable electricity-regulatory framework, so exam questions should distinguish the concept from the exact state-specific percentages.

Exam focus: Separate the concept of banking from the current regulatory rate. Common trap: Do not assume banking is free or unlimited.
