One way of energy conservation and Greenhouse Gases (GHG) reduction is a more rational energy consumption. However, increased energy efficiency does not always leads to the desired outcomes regarding the reduction of consumption and consequently the reduction of GHG. The effect that makes it impossible to obtain the totality of benefits due to increasing energy efficiency is known as the rebound effect. This study aims to focus on rebound effect, controlling them by setting different prices according to the consumption period. A family production function is developed incorporating the electricity consumption, dividing them between peak and off-peak periods. The function for the direct rebound effect is calculated through the elasticity of electricity service comparing to the increased energy efficiency. The consumption variations are thus obtained in each of the periods that are associated with a particular direct rebound effect. In this perspective, a new Time-of-Use tariff (TOU) dual tariff is defined wherein the prices vary in order to cancel the full rebound effect. This way, the increased energy efficiency causes a further decrease of consumption in the critical period (peak period), promoting the smooth of the load diagram. It is proposed a partial sectioning of the dispatch priority of renewables based electricity in a special regime (SR). This procedure allows freeing resources to promote greater energy efficiency. Increased energy efficiency will be accompanied by the TOU tariff we are proposing, making these actually effective efficiency gains, since the proposed tariff ensures the control of RE.
