– LEAP model application
This study develops a scenario-based model to assess the current and future trends in energy demand in Africa and associated greenhouse gas emissions. Future energy demand is forecast on the basis of socio-economic variables such as gross domestic product, income per capita, population, and...
Working Paper
pdf
This paper develops a scenario-based model to identify and provide an array of electricity demand in Africa, and to derive them from the African power system of development. A system-based approach is performed by applying the scenario methodology developed by Schwartz in the context of the energy...
Working Paper
pdf
High levels of inflexible bilateral trade in southern Africa have limited the participation in the competitive short-term markets, leading to inefficient use of energy infrastructure and blocking the Southern African Power Pool’s long-term goal of transitioning from a cooperative to competitive...

– Proposed model for regional power sector integration in Africa
Regional power pools present a significant and potentially defining opportunity for African power systems to develop domestic energy resources, improve system reliability, and contribute to overall economic development. Hydropower is expected to play a significant role in many regional power pools...
Working Paper
pdf
As the technology of climate-dependent energy sources is improving—both cheaper and more efficient—the energy sources are becoming more accessible for many of the nations in Africa. However, little is known about the underlying climate that would therefore be harvested by renewable technologies...

– Preliminary study of the Inga 3 Dam
Large hydropower dams are at the centre of a debate weighing the value and costs of renewable energy against the risks of climate change. The debate is especially relevant on the African continent, which offers vast hydropower potential, but which is exposed to possible climatic changes. This paper...
Working Paper
pdf
– A hybrid assessment
Projections of regional changes in surface air temperature and precipitation for the greater Nile River basin and northern Africa are presented. The probabilistic projections are obtained through a technique that combines projections of the MIT Integrated Global System Model with climate-change...

– Case Study: Zambezi Basin and South Africa
The present study develops a reliability assessment method of wind resource using optimum reservoir target power operations that maximizes the firm generation of integrated wind and hydro power. A combined water resources model for a system of reservoirs that implements a priority based linear...

– Evaluating Carbon Taxes and Electricity Import Restrictions
We link a bottom-up energy sector model to a recursive dynamic computable general equilibrium model of South Africa in order to examine two of the country’s main energy policy considerations: (i) the introduction of a carbon tax and (ii) liberalization of import supply restrictions in order to...
Working Paper
pdf
In spite of not being ‘public goods’ in the strict sense of the term, public provision has been a common way of supplying utilities services around the world. Among the major reasons underlying the dominant position of the public sector as the provider of infrastructure are the recognition of the...

– Subsidies and Service Obligations
Any infrastructure reformers concerned with social issues in a developing country need to address two problems. The first is increasing access by the poor, and the second is ensuring consumption affordability, i.e. the ability of the poor to pay for both consumption and the amortization of the...
Working Paper
pdf
The privatization of the national public utilities that took place almost a decade ago in Argentina seem to be explained by the persisting deficits of the enterprises, a general dissatisfaction with their performance and the difficulties government faced in their control. During the period of...

– Access to Basic Services in Bolivia
This paper analyses the privatization of utilities in Bolivia, detailing the particularities of the capitalization mechanism which was used for this purpose. The analysis suggests that capitalization and regulation, and the liberalization of the utilities sector more generally, succeeded in...
Working Paper
pdf
Relying on a general equilibrium model of Argentina’s economy calibrated for 1993 and internalizing all productivity and scale gains achieved up to 1999, this paper isolates the distributional effects of utilities reform from the impact of other reforms taking place in the country during the 1990s...
Working Paper
pdf
Privatization has been one of the primary factors generating changes in the Chilean economy over the last decade. Privatization has faced some opposition due part to its uncertain effect on employment and prices. Despite the importance of the topic, only few attempts have been made to analyse...
Working Paper
pdf
Almost five years after privatization took place in electricity and telecommunications, and major reforms had been carried out in the administration of water, the results is not clear a priori. In order to elucidate the panorama, this research tries to assess the consumption and welfare impacts of...
