The purpose of this paper is to explore the financial and economic aspects of the renewable energy sector aiming to develop and present a project feasibility analysis model that allows the public sector to master plan socially beneficial infrastructure projects and to find financially viable options for private investments. This paper develops a general frame that can be harmonized to a certain project by applying relevant country specific schemes.

The cost-benefit analysis (CBA) approach is used to develop relevant formulas aiming to compare the economic internal rate of return (EIRR) and financial internal rate of return (FIRR) of the possible investment options. The IRR method is used for the development of a platform that will allow comparing different project alternatives and choosing an optimal model for both public and private partners. A case study approach from Uzbekistan is used to highlight the implementation possibilities of the model based on a certain country example.

This paper develops a decision-making frame allowing the public sector to find organizational options that provide economically viable projects and at the same time attract private investors in the latter. The designed map of possible benefits, costs and revenue mechanisms allows practitioners to analyze the economic and financial viability of the existing combinations by using the developed model.

The developed model will allow the public sector to use the needed data on different possible design models in the developed formulas in order to identify the EIRR and FIRR of each option. Nevertheless, the application of the model will be possible after considering country specific options needed for CBA. The private sector can use the model to identify the financially acceptable options for the investments.

The paper provides the decision makers with a sound tool to identify the possible combinations of the options to conduct a relevant project with private investments in the renewable energy sector and to choose the model that generates the highest social welfare.

The purpose of this paper is to introduce a project development framework (PDF) aiming to find socially beneficial public infrastructure provision (PIP) projects in the transport sector. From this perspective, the current paper focuses on the framework of finding an optimized PIP organizational model based on which the projects will be both economically and financially viable and will meet the interests of all the stakeholders. From this perspective, the objective of the current paper is to find in the design phase of the projects, a PIP organizational model for the transport sector, that generates the socially required economic internal rate of return (hereinafter EIRR), thus providing the society with the added social values from the relevant infrastructure projects and, at the same time, ensuring relevant level of the financial internal rate of return (hereinafter FIRR) for the private companies interested in investing in relevant assets. This allows finding socially beneficial PIP organizational model according to the adopted PDF.

The methodology aiming to develop the PDF focuses on analyzing both the economic and financial effectiveness of the PIP projects by exploring different combinations of available options for business, contractual, and financial models of relevant projects. Based on the example of the Republic of Armenia it is shown how the EIRR can be calculated for the PIP projects using the adopted PDF by taking into consideration the transport sector specifics of the country.

The main advantage of the designed framework is that it focuses on the calculation of the EIRR not only based on the different design options, but also explores the influence of the chosen procurement models on the economic output of the projects. The identification and the calculation of the positive and negative externalities (benefits and losses of the projects) in the economic values within the current PDF serve as the main instrument for the development of the PIP optimized socially beneficial/viable organizational models. The main privilege of the paper is that it considers the social aspect of the project together with the financing aspect without extruding any interests of the parties.

The uniqueness and the novelty of the adopted PDF is that it considers the efficiency of the PIP projects based on the analysis of not only the design options that influence the economic and financial output of the projects, but also compares the impact of the different combinations of the existing privatization, partnership, contractual, financial, and business models on the level of the EIRR and the FIRR. The socially beneficial infrastructure (economically viable) model generates economically and financially viable projects. Thus, the public partner is provided with the highest social value while the private partner is guaranteed a desired financial return.
