This document discusses an energy conservation scheme based on tariff modification for domestic users. It proposes a new tariff rate structure that provides incentives for low consumption and penalties for high consumption. This aims to motivate consumers to reduce energy usage without causing losses for electric utilities. The existing structure provides 100 free units, which does not encourage conservation and causes losses. The proposed system calculates bills based on consumed units and compares to averages to determine incentives or penalties. The goal is to reduce residential energy usage through this modified tariff approach.
