Territorial analysis for energy supply of western Turin area from alternative renewable sources: impact and potential

It is now generally assumed that a radical reversal in economy is needed in order to cope with the effects of climate changes and to improve the resilience of populations in relation to these effects.

In fact, European policies for climate change and economic recovery due to Covid-19 (Guidance to Member States, Recovery and Resilience Plans, 8th Environmental Action Program) are supposed to work in synergy to promote green and efficient energies, shifting the cost/benefit ratio in favor of renewable natural resources. As part of these policies, Italy is increasing the number of mini hydroelectric plants (max. power of 1000 kW), which are considered advantageous both in economic and environmental terms without being in contrast with the surrounding environment.

The aim of this study is the evaluation of potential production of hydroelectric energy, by means of mini hydroelectric, in the western area of ​​Turin, considering lowland areas (such as the Municipalities of Collegno, Druento and Alpignano) and high valley areas such as the Municipality of Coazze and upper Sangone Valley. In these investigated area, the development of mini hydroelectric could possibly result in partial or entire energy self-sufficiency.

In order to comply with environmental policies, a feasibility study will be conducted, based on geological, hydrogeological, morphological, ecological and climatic components.

The study will also be congruent with European and national guidelines regarding the Environmental Impact Assessment, so as to evaluate any possible plant locations in terms of environmental impact.

The geological and geomorphological data collected will also be employed to evaluate the possibility of reuse of the materials which could possibly accumulate in the reservoirs, in accordance with the policies of the Green Communities.
