Project Presentaton

In February 2012, the Summit of ECOWAS Heads of States and Government approved the revised ECOWAS Master Plan for the Generation and Transmission of Electric Power which identifies the Côte d'Ivoire, Liberia, Sierra Leone, and Guinea (CLSG) Interconnection Project as one of the five (5) priority projects of the West African Power Pool (WAPP) for the West African Sub-Region.

The objective of the WAPP is to establish a regional electricity market in West Africa through the appropriate development and implementation of key infrastructures so that all ECOWAS member states are given access to economic energy resources.

In order to accelerate the implementation of the CLSG interconnection project, WAPP uses a Special Purpose Companies as a vehicle of achieving this objective. Accordingly, the four countries have duly signed and ratified an International Treaty establishing a Regional Transmission Company (RTC) known as TRANSCO CLSG with the mandate to finance, construct, own, operate and further develop the CLSG transmission interconnection line.. TRANSCO CLSG is fully established and has been operational since September 5, 2014 following the appointment of its General Manager and his subsequent assumption into office at its Headquarters in Abidjan, Côte d’Ivoire.

When the CLSG Interconnection Project is realized, it will interlink the completed WAPP Coastal Transmission Backbone Interconnection Project and the proposed (on-going) OMVG/OMVS Power System Development Projects which are part of the WAPP Priority Projects. It is expected that the on-going Inter-zonal Transmission Hub and the North Core Transmission Projects when completed, will connect the existing robust 330kV transmission corridor in the sub-region to close the ring of the proposed WAPP High Voltage Grid mesh.

PRESENTATION

The project is being implemented in four (4) Countries:

  • Côte d’Ivoire(C)
  • Liberia (L)
  • Sierra Leone (S)
  • Guinea (G)

There are two main infrastructures to be built within the framework of the project:

  1. The Transmission Line

Four main 225 kV high voltage Transmission Lines (TL):

  1. 1 TL Man (CI) - Yekepa (L) - Nzérékoré (G) --- 202 km
  2. 2 TL Yekepa (L) - Sierra Leone/ Liberia border --- 463 km
  3. 3 TL Sierra Leone/ Liberia border - Yiben (SL) --- 419 km
  4. 4 TL Yiben (SL)- Kamakwie (SL) - Linsan (G) --- 220 km

The total length of the high voltage TL is approximately 1 349 km.

The expected power to be transmitted when the two (2) circuits will be fully operational is 290 MW.

  1. The Substations

Within the framework of the CLSG project, eleven (11) Substations (SS) will be constructed and one existing SS (Man) will be extended. The locations are detailed in the table below:

ENVIRONMENTAL AND SOCIAL SAFEGUARDS ASPECTS

1.Political, Legislative and Institutional Framework of the environmental and social aspects

1.1 Political and Legislative Framework

The Environmental and Social Impact Assessment (ESIA) for the project was prepared in accordance with the Environmental Impact Assessment Guide in ECOWAS related to the energy sector; the regulation of Côte d'Ivoire, Liberia, Sierra Leone, and Guinea and the requirements of the funding institutions of the project: AfDB, EIB, KfW and the World Bank.

1.2 Institutional Framework

The institutional framework of the project on environmental and social issues includes environmental protection agencies and other institutions.

1.2.1. Environment Protection Agencies (EPA)

Their mission and attribution:

  • ensure the integration of environmental requirements into development projects and programs;
  • implement the impact assessment process and the assessment of the environmental impact of macro-economic policies

The jurisdiction of these agencies in this project includes:

  • validating the Terms of Reference of the ESIA,
  • assessing the ESIA report,
  • monitoring the implementation of the Environmental and Social Management Plan (ESMP) monitoring the environmental compliance of Companies’ activities in the energy sector, by carrying out environmental audits.

These are the agencies that deliver the Environmental Permit or Environmental Compliance Certificate.

In Sierra Leone, the EPA is known as SL_EPA; in Liberia EPA; in Guinée, the ‘Bureau d’Études et d’Évaluation Environnementale (BGEEE)’ and in CI, the ‘Agence Nationale de l’Environnement’

1.2.2. Other Institutions

  • Cote d’Ivoire: Ministry of Construction, Housing Sanitation and Urbanization (MCLAU). This Ministry is responsible, through a commission, of the validation of Resettlement Action Plan (RAP) of the Project Affected People. Hence, the Resettlement Action Plan of the CLSG project has been validated by this ministry in Côte d’Ivoire.
  • Liberia: Ministry of Lands, Mines and Energy (MLM&E); the Bureau of Land Survey of this Ministry is the technical section of the Government that handles land demarcation and land survey.
  • Sierra Leone: Ministry of Lands Country Planning and Environment (MLCPE) through the land valuation committee will participate in the process of land acquisition and transfer of titles as the final owner of land to be acquired and witness the whole process of compensation and resettlement.
  • Guinée : Ministry of Territorial Administration and Decentralization (MATD) through the National Directorate of Territorial Administration and Decentralization (DNATD) is the leader of all the institutions that will be involved in the implementation of the RAP of the interconnection project. It must ensure the effective implementation of the measures contained in the RAP. It must also prepare and submit for the signature of the Minister in charge of the administration; the decree setting up land commissions in the prefectures affected by the interconnection project.
  1. 2.Environmental and Social Safeguards Vision at TRANSCO CLSG

Within the framework of the implementation of the interconnection project Côte d'Ivoire-Liberia, Sierra Leone and Guinea, our objective ofthe environmental and social safeguards is to prevent and minimize in the best ways possible the environmental and social impacts of the project on people located in the corridor of the high voltage 225 kV line of about 1,349 km and the environments of the 4 countries alike.

We envisage to apply social safeguards standards-based on the institutional and regulatory principles of the CLSG countries and the international best practices as laid out by our donors namely the World Bank, EIB, AfDB and KFW.

TRANSCO CLSG, through its environmental and social safeguard policy, commits:

  • to operate on the basis of an open communication with all stakeholders and persons affected by the project (PAPs) in order to build a positive and lasting relationships with them while involving them in all stages of the project.
  • to work in transparency, respect of the customs, beliefs,values and patrimony of the different communities located across the line.
  • to ensure that all those affected by the project receive fair and equitable compensation for all damages.
  • to mitigate the negative impact of the project on the environment and to provide a sustainable development.
  • to ensure that all contractors involved in the construction of the line work in accordance to our objective of the environmental and social aspects, in respect of the environment and population of the CLSG countries.

COUNTLESS BENEFITS OF THE CLSG PROJECT

“In recognition of the benefits that this project will bring to the CLSG countries, it was singled out by the G20 as a priority project at the 2011 Cannes meetings.”

Regional Integration of electricity networks

It provides the power utilities of the region with a vehicle to achieve the vision embodied in the ECOWAS Energy Protocol –that of creating a “level playing field” to facilitate the balanced development of diverse energy resources of the ECOWAS Member States for their collective economic benefit, through long-term energy sector cooperation, unimpeded energy transit and increasing cross-border electricity trade.

Reducing the greenhouse gas emissions

The interconnection results in reduced use of hydrocarbon fuels in the four countries and helps avoid more than 5.6 million tons of carbon over the lifetime of the project in comparison to the “without” project scenario. Assuming a damage cost value of US$20 per ton, overall gains from avoided carbon emissions can be valued at US$62.5 million in net present value (NPV) terms.

Economic Recovery and Poverty Reduction

The project will contribute to economic recovery and poverty reduction through improved access to essential power supplies in the CLSG area. This will be accomplished through the re-construction of essential infrastructure and strengthening of institutional capabilities to plan, procure, operate, maintain and sustainably manage these services. It will provide support for targeted critical investments with the aim of developing the most economic power resources in the CLSG area and making services available from a regional power system that overcomes the structural inefficiencies presented by the small sizes of the individual economies.

Improving the Financial Performance

The CLSG project will improve the financial performance of at least some of the national utilities significantly, as the energy imported would displace more expensive generation sources. In turn, the combined regional and domestic impacts will support the transition to normally functioning power utilities in these countries with lower cost, more sustainable generation and more effective means to control and optimize system expansion and operations.

Developing Alternative Power Supply Model

Grid connection of mining sites would allow a number of alternative power supply models to be developed. The CLSG countries are endowed with vast areas of world class iron ore deposits that once developed could represent a major demand on the CLSG line. Indeed the CLSG line goes closely past the most significant mining areas and the potential amount traded by the mining companies is high. If mining demand were interconnected to the grid, different supply arrangements could be developed that would allow the energy supply surplus from mining to be sold to the grid (either bilateral or to the utilities) or allow the development of large supply generation plan to meet the mining demand while using the CLSG line.
