The Economics of Renewable Energy Expansion in Rural Sub-Saharan AfricaAccelerating development in Sub-Saharan Africa will require massive expansion of access to electricity -- currently reaching only about one-third of households. This paper explores how essential economic development might be reconciled with the need to keep carbon emissions in check. The authors develop a geographically explicit framework and use spatial modeling and cost estimates from recent engineering studies to determine where stand-alone renewable energy generation is a cost effective alternative to centralized grid supply. The results suggest that decentralized renewable energy will likely play an important role in expanding rural energy access. But it will be the lowest cost option for a minority of households in Africa, even when likely cost reductions over the next 20 years are considered. Decentralized renewables are competitive mostly in remote and rural areas, while grid connected supply dominates denser areas where the majority of households reside. These findings underscore the need to de-carbonize the fuel mix for centralized power generation as it expands in Africa.

Turkey’s Energy Transition Milestones and ChallengesThrough a variety of interlinked measures, Turkey’s energy reforms have achieved energy security for a fast-growing economy with rapidly increasing energy needs. These measures include legislation regarding electricity, gas, renewable energy, and energy efficiency; the establishment of an energy sector regulatory authority; energy price reform; the creation of a functional electricity market and large-scale introduction of natural gas; the restructuring of state-owned energy enterprises; and large-scale private sector participation through privatization and new investment. The objectives of this are to: (a) inform future energy reforms and reformers seeking to learn and benefit from Turkey’s experience, and (b) contribute to the dialogue on future energy reforms in Turkey. The report will present Turkey’s accomplishments in developing and implementing market-oriented energy reforms as well as selected key reform challenges going forward. In terms of reform milestones, the primary focus is on the electric power and natural gas sectors, although energy pricing and subsidies in the petroleum sector are also addressed. The report covers mainly the period starting from 2001, when progressive electricity and natural gas market laws were enacted, though the preceding period - from the opening of the energy sector to private investment in 1984 up to the enactment of the new energy market laws in 2001 - is covered briefly to present key milestones and to highlight key lessons. In terms of future challenges, the report discusses the ongoing and unfinished liberalization of the electricity and gas markets as well as required government support, including governance, in the energy sector. The challenges include the reform of the natural gas market, further development of the electricity market, and governance issues in the energy sector. Discussion of environmental and social issues and challenges has been integrated into the relevant sections.

Vietnam Power Sector : Generation OptionsThis report discusses the energy sector in Vietnam. The central task for the energy sector is to meet demands for electricity in sufficient quantity and of an acceptable quality, in as commercially and financially efficient a way as possible. Several issues arise if this task is to be accomplished in the short and medium term. They are: optimizing power investments; financing the investments that must be made; implementing the reforms in the power industry and restructuring EVN; improving access and service quality; and addressing shortcomings in pricing and tariffs. This study discusses the first of these issues, though inevitably there is some overlap. The study has four specific objectives: (1) to inform decisions about technology choices; (2) to inform decisions on energy and energy sector policy; (3) to inform the energy sector planning process; and (4) to inform the internal discussion within the Bank on how Vietnam's energy sector development can be assisted.
