Motivations for engaging in PPP power projects in Ghana: comparison of the public and private sectors

Abstract

Purpose In the past few years, the public–private partnership (PPP) model has become increasingly popular in the infrastructure projects of developing countries, especially in the power sector. The purpose of this study is to ascertain the motivations for engaging in PPP power projects in Ghana by comparing the public and private sectors. Design/methodology/approach Questionnaires were used to elicit responses from respondents using a two-round Delphi survey. Mean score ranking was used to rank the motivation factors, while reliability analysis was conducted using Cronbach alpha coefficient, and level of agreement was tested using Kendall’s concordance. One-sample t-test assessed the relative significance of these motivation factors. Findings For the public sector, the topmost motivations were achieving improved value for money; access to additional capital; increased certainty of projects; greater efficiency of project delivery services; and improved ability to deliver new infrastructure. For the private sector, the topmost motivations were obtaining of investment support; improvement in private sector’s international image; synergy with public sector; sharing of risks; and gaining of profits. Practical implications The findings of this study will lead to increased knowledge on the motivation factors for the public and private sectors engaging in PPP power projects in Ghana. Originality/value The output of this research contributes to the checklist of motivation factors for engaging in PPP power projects and contributes to the development of PPP practice.

Evaluation of risk factors in Ghanaian public-private-partnership (PPP) power projects using fuzzy synthetic evaluation methodology (FSEM)

“…Changes in the private investor may arise if there are disputes or contractual abuses which cause the private sector to exit the consortium (Ke et al. , 2013; Kukah et al. , 2022c).…”

“…Design change (risk impact = 4.88, rank = 21, significance = 0.712) was ranked highly by the respondents. Improper designs at the onset or inflexible adjustments may lead to design changes in PPP power projects (Kukah et al. , 2022c).…”

“…Private investor change was ranked 2nd with a risk significance index of 30.73, high probability of occurrence (5.52), high severity (5.57) and high impact (5.54). Changes in the private investor may arise if there are disputes or contractual abuses which cause the private sector to exit the consortium (Ke et al, 2013;Kukah et al, 2022c).…”

Strategies to Reduce the Impact of Resource Consumption in the Ghanaian Construction Industry

“…The techniques were ranked using a mean score ranking based on mean values and standard deviation. On a statistical data set, standard deviations represent the amount of variability and consistency associated with respondents' interpretation of variables (Field, 2009;Kukah et al, 2022b). It is considered crucial in terms of statistical credibility and data dependability (Field, 2009;Motulsky, 2003).…”

Revolutionising Public Private Partnerships: A Transition to the Fifth Industrial Revolution

“…PPPs can take advantage of these mechanisms to improve efficiency and performance, making them more adaptable, sustainable, and competitive. Other major benefits of the 5IR on which PPPs can capitalize, include greener solutions, cost optimization, customization and innovation [47].…”
