Per capita energy consumption is high in urban locations of any country. In this context, this article explores the deployment of standalone photovoltaic (PV) water pumping units in every household of a sustainable city. The various photovoltaic water pumping schemes and the domestic pumping requirements of a city in India are given in this paper. The peak shaving of load and reduction in line losses due to PV pump deployment on a secondary distribution transformer in a residential locality of the same city is investigated to bring out the advantages of the above policy initiative. The need for a legislation to install PV water pumps is thus brought out in this paper.
