Micro hydroelectric power: Feasibility of a domestic plant

The article presents the analysis of technical and economical feasibility of a small hydropower plant for domestic use (micro-hydro), how it can be implemented in Prignano sulla Secchia (MO, Italy). The necessary information and input regarding the duration of the discharge curve are reconstructed here through direct measures and indirect methods. Different solutions and combination of pipes and turbine and storage tanks have been analyzed in order to identify the most convenient. In particular the following alternatives have been considered: - systems with or without a storage tank; - the possibility of selling the produced energy directly to the network or using the energy for own consumption. For each solution the yearly energy production was evaluated. Different scenarios were considered: cases in which produced energy is consumed directly or cases in which the produced energy is sold to the electric network through an exchange contract in place. No solution is currently depreciating rapidly (<5 years), but given the negligible investment, the cost of which is likely to grow, as well as incentive policies, we conclude that the potential for generation of electricity for own use and consumption is promising.
