Summary of Liberia's Energy Sector Development Options

Core Content

This document outlines options for the development of Liberia's energy sector, focusing on expanding electricity access and modernizing energy services. It is part of the Africa Energy Unit (AFTEG) Energy Sector Policy Notes Series and was published in October 2011 by the World Bank.

Key Information

Current Energy Access in Liberia

• In mid-2011, Liberia had one of the lowest rates of electricity access in the world.
• Only 0.58% of Monrovia's population had access to public electricity.
• No publicly supplied electricity service was available outside Monrovia except for a limited municipal mini-grid in Gbarnga, Bong County.
• Over 80% of household energy needs are met through thermal energy, primarily charcoal and firewood.
• Charcoal production consumes about 960,000 trees annually around Monrovia, threatening forest resources.

Impact of Civil War

• Liberia's power sector was severely damaged by 14 years of civil war, ending in 2003.
• By 2005, most infrastructure had been destroyed, including the Mt. Coffee hydropower plant and the entire transmission and distribution network.
• Operations of the Liberia Electricity Corporation (LEC) ceased, necessitating a full reconstruction of the power system.

Economic and Social Context

• High electricity costs and poor service quality in 2010 hindered long-term economic development.
• The price of electricity from the grid was US$0.43/kWh, possibly the highest in Sub-Saharan Africa.
• Alternative energy sources like dry-cell batteries, car batteries, candles, and kerosene are used by those without access, at significantly higher costs.

Main Scenarios and Supply Options

Demand Scenarios

• Conservative Demand Growth: Assumes slower economic growth, leading to moderate electricity demand.
• High Demand Growth: Assumes more pronounced economic growth, especially in commercial and mining sectors, leading to higher electricity demand.

Supply Options

The following are the key supply options analyzed for Liberia's energy development from 2010 to 2040:

Key Findings

• A least-cost expansion plan for the medium term (until 2015) and long term (until 2040) was developed using the GAMS model.
• The plan suggests the construction of a range of hydropower plants, including the rehabilitation of the Mt. Coffee plant by 2015 and the development of the St. Paul River and Mano River projects by 2020.
• Thermal power options include diesel and HFO, with HFO being more cost-effective.
• The WAPP transmission interconnection for CLSG (Côte d'Ivoire, Liberia, Sierra Leone, and Guinea) is expected to become operational in 2015, which will help bridge the emerging supply gap.

Rural Electrification Strategies

• Decentralized off-grid solutions, such as mini-grids and stand-alone systems, are recommended for rural areas due to limited grid coverage.
• Renewable energy technologies (solar, biomass, and hydropower) are well-suited for off-grid applications.
• Private sector models like dealer sales and fee-for-service are suitable for rural electrification, but require supportive government policies.
• The Rural and Renewable Energy Agency (RREA) is encouraged to develop a rural energy master plan and take leadership in implementing these strategies.

Policy and Financing Recommendations

• A clear and timely implementation of the National Energy Policy (NEP) is essential.
• The RREA and its Rural Electrification Fund (REFUND) need to become fully operational.
• Public financing is preferred for initial investments due to the lack of a solid customer base.
• A regulatory environment should be established to facilitate future private sector interventions.
• Financing from multilateral partners, including the World Bank, is crucial for the reconstruction of the energy sector.

Challenges

• The LEC's financial situation is precarious, with average revenue still below operating costs.
• Meeting the NEP targets for electricity connections by 2015 seems difficult under current policies.
• Fuel supply challenges persist, including high costs and lack of international safety standards.
• Rehabilitation of diesel and HFO supply facilities is expected to be completed by 2012.

Conclusion

This report provides a comprehensive analysis of Liberia's energy sector development options, emphasizing the need for strategic planning, policy support, and both public and private financing. It outlines a path for sustainable energy development, focusing on expanding access, modernizing services, and leveraging renewable and thermal resources to meet growing demand.
