Power generation, consumption and management interact in many ways with water resources, yet surface water management differs from groundwater management. About 2.6% of Brazilian energy consumption is used for groundwater supply. Actions for energy efficiency in this sector can bring energy savings.

A time-of-use rate was recently introduced to incentive consumers to manage their demand in order to avoid electricity consumption during on-peak hours. Solar Domestic Hot-Water Systems can be a useful tool to reduce the energy consumption and on-peak power demand but represents additional investment costs, so depending on the relation between the different levels of electricity costs, they can be an economically feasible option. The present work shows an optimization procedure to define the sizing of the Solar Domestic Hot Water System for a study case and also presents multi-objective optimization analysis considering the conflicting objectives of the consumers that want a lower monthly expenditure and the utility that wants to smooth the demand curve. Results shows that considering the actual regulation, solar heating systems are economically feasible for both rates with a slightly advantage to the time-of-use rate. Reduction in the on-peak electricity consumption is always achieved, but more precise results needs a more realistic distribution of the heating demand along the year.
