The unaccountability of state Electricity Boards (SEBs) in India has led to gross inefficiency at all levels. This article examines significant aspects of inefficiency costs involved in SEBs functioning.

Part II deals with the supply cost of electricity, tariff and revenue, as well as financial performance.
