A WORLD BANK STUDY

evisiting Public-Private Partnerships in the Power Sector is part of the World Bank Studies series. These papers are published to communicate the results of the Bank’s ongoing research and to stimulate public discussion. Given the chronic power shortages that numerous developing countries face, as well as the global need to keep pace with demand, understanding the drivers of public-private partnerships (PPPs) in energy is critical. While many private electricity projects have been delayed and financing costs have increased, the impact of the global financial crisis on electricity in developing countries has been less severe than that of previous crises. This improved resilience in developing countries stems from generation capacity expansion, electricity sector reforms, better regulatory frameworks, and short-term solutions (such as rental power plants). This study reports the evidence from statistical analysis and a sample of case studies. It proposes a novel analytical approach to modeling PPPs, using a two-stage procedure based on Heckman’s sample selection, which distinguishes between those factors that determine whether private investment in energy takes place and those that influence the volume of investment. The results of the analysis provide the following conclusions:

Both general governance and regulatory instruments—not the subsequent level of investment— primarily affect investors’ decisions to enter the various power sector markets, indicating that investors seem to be adequately protected against risks. Support mechanisms, like feed-in tariffs, are crucial for attracting investors in renewable generation, but they do not succeed in displacing fossil fuel investment and they could play a bigger role in affecting the level of investment in renewables. There is a significant trade-off between effectiveness and efficiency of alternative instruments for deploying renewables. In the study, feed-in tariffs tended to be quite effective but were set on the high side, which reduced incentives to cut costs and posed significant strains on already stripped national budgets. Competitive auctions, conversely, tended to be efficient but initially low and not always the most effective instrument. Countries can scale up renewables by following different paths. For Brazil, the move from feed-in tariffs to auctions enabled it to both reduce costs and deploy additional capacity. Peru followed in Brazil’s path, opting for auctions instead of feed-in tariffs. China’s move from competitive tenders to feed-in tariffs allowed for discovery effects to determine the right level of prices to attract private investment in renewables.
