ECOWAS Region - Support to RE Flagship Projects

ECOWAS, the Economic Community of West African states, comprises 15 West African countries: Benin, Burkina Faso, Cabo Verde, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone and Togo. The overall GIZ project supports the regional dissemination of experience concerning renewable energies and aims at improving the capacities of utilities in the long term.

Output Area B of the project "Generation - RE flagship projects" follows a two-pronged approach:

1. Documentation of information on and experience with existing RE flagship projects; 
2. Support to the development of planned projects through technical assistance for project development and transaction advice, accompanied by documentation of experience.

Provision and coordination of a pool of short-term experts to carry out the following tasks:

• Support to ECREEE in the process of screening, evaluating and prioritizing RE projects or promotion schemes
• Support to project developers and government representatives on technical, legal, financial and economic aspects of selected projects.
• Monitoring of selected projects during critical phases of their development and reporting of required action.
• Compilation of experiences with the selected projects and support to ECREEE / other institutions in the region in the dissemination of key findings and lessons learnt.
• Assistance to ECREEE and GIZ in supporting selected ECOWAS member states in creating an enabling legal, regulatory and administrative framework for grid-connected RE projects.

The above tasks cover PV, wind, small hydropower and biomass technology.

Uzbekistan - Development of Wind Power Potential

Uzbekistan intends to reduce its greenhouse gas emissions by diversifying the energy generation mix. Several small-scale wind power installations exist, most of them, however, have local (off-grid) or pilot character. The project studied and assessed the potential for installing wind generation facilities on an industrial scale.

Ghana - 100 MW Solar Project in Nyimbale - Sankana

Home Energy Africa (HEA) has obtained a siting clearance approval from the Energy Commission of Ghana for the installation of a 100 MW solar PV plant at Sankana, Nadowli-Kaleo District, Upper West Region. The site has a size of 200 hectares and shall be connected via a 161 kV power line. The electricity that will be produced by the planned PV plant shall be sold to the Electricity Company of Ghana (ECG) under a long-term Power Purchase Agreement (PPA).

HEA has retained the clean energy financial advisor GreenMax Capital Advisors to manage the solicitation of the different services required for the development of the above plant.

Pakistan - Study to Determine the Limit of Integrating Intermittent Renewable (Wind & Solar) Resources onto Pakistan National Grid

The Government of Pakistan encourages the development of renewable energy to close the gap between electricity demand and supply. The National Transmission and Dispatch Company (NTDC) is already in the process of integrating wind power, and many large and small solar parks have been added to NDTC's pipeline. NDTC requested to conduct the present power system study to clarify the limits of integrating RE into Pakistan's grid. The study includes the following subjects:

• Planning studies (load flow, dynamic and transient stability, impact of fault levels on substation protection and design, reactive power and voltage control, power quality issues, system flexibility requirements, system's frequency response)
• Operational studies (operation and control strategy, dispatch policy, methodology to forecast wind and solar power availability, determination of active spinning reserve)
• Financial analysis (determination of financial impact of wind and solar energy resources on Pakistan's overall energy mix)

All activities are closely coordinated with NTDC and the Alternative Energy Development Board (AEDB).
