Final Report: Sub-Saharan Africa Refinery Project - Volume II-A Summary

Core Content

This report, submitted to the World Bank and the African Refiners Association (ARA), presents a comprehensive analysis of the impact of transitioning to cleaner fuel specifications in Sub-Saharan Africa (SSA). The study is part of a two-part initiative that includes a Refinery Sector Study and a Health Study. The focus is on the economic and environmental implications of adopting AFRI-4 fuel standards, which are modeled after EU regulations.

Main Objectives

• To evaluate the effects of cleaner fuel specifications (AFRI-4) on refining operations, investment costs, and air quality in SSA.
• To assess the economic and health impacts of transitioning to AFRI-4 standards.
• To analyze the potential for SSA refineries to modernize and compete in the global market.

Key Findings

Fuel Specifications

• The AFRI-4 standards require:
  • Gasoline: Sulfur content ≤ 150 ppm, benzene content ≤ 1%.
  • Diesel: Sulfur content ≤ 50 ppm.
• These standards aim to reduce sulfur dioxide (SOx) and particulate matter (PM) emissions, which are harmful to both the environment and human health.
• The study assumes that all SSA refineries will reach AFRI-4 standards by 2020.

Modeling Approach

• The WORLD® model is used to simulate the global and regional impacts of fuel specifications.
• The model considers:
  • Crude oil price, supply, and demand.
  • Refinery configurations, capacities, and investment costs.
  • Product specifications and trade flows.
  • Environmental and health impacts.

Economic and Environmental Impacts

• The transition to AFRI-4 standards involves incremental investment costs and increased supply costs.
• These costs are analyzed for different scenarios, including:
  • Base Case: Current refining conditions (2008).
  • 2015 Case: Impact of AFRI-4 standards in 2015.
  • 2020 Constrained Case: Impact under current fuel specifications.
  • 2020 Open Market Cases: Impact under both favorable and unfavorable conditions for SSA.

Oil Price Projections

• Oil prices are a critical input in the WORLD® model.
• The study uses EIA's 2009 Annual Energy Outlook (AEO2009) as a baseline.
• Adjustments were made to reflect the global economic recession:
  • Light sweet crude prices: $54.50/barrel in 2010, $65/barrel in 2015, $75/barrel in 2020 (all in 2007 dollars).
• Prices for other crude oils are derived based on quality and location.

Regional Groupings

• SSA countries are divided into three large demand regions: West, East, and South.
• These regions are further split into nine refinery supply regions.
• Exhibit 1-2 and Exhibit 1-3 illustrate the demand regions and refinery supply regions, respectively.

Key Assumptions

• Global Assumptions:
  • Use of the WORLD® model.
  • Crude oil price trends based on EIA and IEA data.
  • Regional demand and supply patterns.
• SSA Assumptions:
  • Refineries will transition to AFRI-4 standards by 2020.
  • Fuel specifications will affect:
    • Refinery operations.
    • Investment and operational costs.
    • Environmental emissions and health outcomes.

Cost Benefit Analysis

• The study includes a cost benefit analysis comparing the incremental supply costs of AFRI-4 fuels with the health benefits.
• Monetary valuation of health benefits is provided, including the net present value (NPV) of supply costs versus health benefits over a 10-year period.
• Incremental investment costs and refinery expansion costs are calculated for different cases, including:
  • Base Case (2008).
  • 2015 Case (Current and AFRI-4 specifications).
  • 2020 Constrained and Open Market Cases (Current and AFRI-4 specifications).

Conclusions and Recommendations

• The adoption of AFRI-4 standards will lead to increased refining costs but also reduced environmental and health impacts.
• The economic viability of the transition depends on:
  • The global oil price trends.
  • The market conditions in SSA.
  • The ability of SSA refineries to modernize.
• The study recommends that SSA refineries should:
  • Invest in modern refining technologies.
  • Transition to AFRI-4 standards.
  • Engage in international trade to optimize costs and supply chains.

Summary of Key Cases

Key Information

• The study was funded by the World Bank and co-sponsored by UNEP and IPIECA.
• The WORLD® model is used to simulate the impact of fuel specifications on the refining sector.
• AFRI-4 standards are modeled after EU regulations.
• The economic recession influenced the oil price assumptions.
• The transition to cleaner fuels is expected to improve air quality and public health in SSA.
• Refinery modernization is essential for global competitiveness and environmental compliance.
