Conventionally, the utilities are supplying electricity and water to households through electricity grid and water networks. In this study, the future role of distribution infrastructures has been analysed.

Solar photovoltaic technology is chosen for supplying the household electricity demand. Economics of grid connected PV systems has been analysed with the help of experience curves. Grid parity years for Germany have been calculated as 2012 and 2021 in retail and wholesale electricity market, respectively. Using PV electricity at the time of its generation, real grid parity year would be between 2017 and 2013.

Breakeven year for stand alone PV systems in Cologne is calculated between 2026 and 2034. The breakeven grid access distance has been found around 2.1 km. Without seasonal variations, module size would decrease from 22.1 to 7.8 kWp.

In Nepal, breakeven year for stand alone PV systems is calculated between 2036 and 2026. The rural electrifi cation option from utility’s and consumer’s perspective has also been analysed.

The calculations for an autonomous electricity and water supply household in Germany show that the combined breakeven grid access distance would be about 1.6 km.
