Paradigm shift in the sustainability of water-based power sector – an application of Hydropower sustainability assessment protocol

Abstract

Purpose

The study aims to identify the severe socioeconomic, environmental, and ecological impacts caused by the construction of mega and large hydro-power plants in Uttarakhand, India. In addition to identifying the attributes, the study creates an integrated index that will assist in the development of sustainable hydro-power.

Design/methodology/approach

The methodology used for this impact identification was based on extensive literature review, focused expert discussions and further validation through a primary survey among the stakeholders in the hydropower sector. The sustainability index (SI) was estimated using the fuzzy logic theory.

Findings

The study area SI shows that few projects are in extreme zones, and through suggestive measures, few project sites can be made viable for long-term sustainable project site. A Hydropower Sustainability Assessment Protocol–based conceptual model is also proposed for mitigation of impacts.

Originality/value

Hydropower plays an essential role in access to cleaner and cheaper sources of energy; it defines the usage of water resources toward inflation-free green energy and holds spectacular operational flexibility. Despite the significant advantages associated with hydroelectric power projects, there are adverse side effects as well. The water-based power sector industry contributes to any nation through both economic and environmental ways. Although one-third of the power business in India is carried out through water-based hydropower projects, recent trends in water-based hydropower projects show significant socioeconomic and environmental impacts that create a debate about the sustainability of these projects.
