BACKGROUND
Sri Lanka’s electricity demand has been growing at an average of
6.8% per year from 1986 to 2003 (Amarawikrama & Hunt, 2007).
There is a need for a secure and accessible supply of energy for the
sustainability of modern societies (Tiwari &Mishra, 2012)
Energy generation by renewable energy sources is a solution for the
current energy crisis.
As availability of hydro resources within the country and it is
renewable energy source, energy can be generated sustainably.
BACKGROUND (Contd.)
feasibility study is an analysis of the potential impact of a proposed
project and it is conducted to assist decision makers in determining
whether the project or program will implement or not (Urkiaga et
al, 2006).
Many contemporarily using feasibility factors are there in the
world.
Currently using feasibility factors are not much comprehensive and
cover all the feasibility aspects of a project.
Thus, a comprehensive framework for assess the feasibility of MHP
projects is needed to assess the project success.
AIM OF THE STUDY
Develop a multidimensional framework for feasibility assessment
of mini hydro power projects in Sri Lanka.
OBJECTIVES
The current demand for electricity in Sri Lanka.
The sources of the electricity generation in Sri Lanka.
The implementation and importance of MHP projects.
Investigate the current level of implementation of MHP in Sri
Lanka.
Identify feasibility assessment perspectives and criteria for MHP
projects feasibility.
Develop a conceptual hierarchy for feasibility assessment of MHP
in Sri Lanka.
Multidimensional framework for feasibility assessment of MHP
projects in Sri Lanka.

LITERATURE FINDINGS (Contd.)
Many other MHP project feasibility criteria according to the
expert’s recommendations.
Theoretical hierarchy for assess the MHP project feasibility
6 feasibility perspectives have been identified with 42 criteria
respectively to each perspective.
PRELIMINARY QUESTIONNIRE SURVEY
Survey carried out among 10 MHP industry expertise.
Data were analyzed, and concluded the perspectives and criteria
for MHP project feasibility assessment and developed the
conceptual hierarchy.

AHP QUESTIONNAIRE SURVEY
Survey was carried out among 30 MHP industry expert’s within
different organizations.
Data were analyzed using AHP (Analytical Hierarchical Process)
tool.
Developed the multidimensional framework with prioritized
perspectives and criteria for assess the MHP feasibility in Sri
Lanka.
