The proposed study should review the impact of integrating up to 7,200 MW of wind power into the power grid. It should examine the impact of wind farm characteristics on the potential static and dynamic stability issues, and to investigate how EEHC can require certain technical specifications from the manufacturers and developers to minimize the impacts on the grid stability. The main activities to be covered by the study include:
(i) Review of available technical documentation;
(ii) Review and validation of dynamic PSS/E and/or DIgSILENT model of the Egyptian power system;
(iii) Assessment of transmission capacity requirements based on load flow studies;
(iv) Assessment of load-following capability and reserve capacity requirements;
(v) Assessment of protection and FRT capability requirements for both symmetrical and asymmetrical faults based on dynamic studies;
(vi) Establishing grid code for integration of wind power plants; and (vii) Developing suggestions on how to integrate wind forecasting in power system operation and planning in Egypt.
The project aims at supporting Egypt's efforts towards implementing a sustainable energy strategy, including energy diversification and reduced dependence on fossil fuels through large-scale deployment of renewable energy technologies, especially wind energy. It will also contribute towards some indirect benefits such as transfer of technology, job creation, and environmental sustainability.
The complexity of the interconnection of wind farms to the power grid stems from the fact that wind energy is rather unstable and available only during certain hours of the day. By its nature wind power generation may drop suddenly. To keep the grid operation stable, there is a need to ensure that other power generation sources are available to compensate for the drop. The Egyptian power system is already highly constrained vis-
The challenges of renewable energy development are rather unique due to the requirements to create an incentive framework that is conducive to innovation, and an implementation system that is capable of bringing a variety of stakeholders together. Egypt has taken significant steps towards: (a) launching an accelerated program of wind power development; (b) enabling both public and private sectors to invest jointly or separately; and (c) establishing the associated manufacturing and services. Egypt has an ambitious program to expand its efforts in all these areas. In order to continue with these efforts it would need to formulate the technical requirements for equipment manufacturers and power developers in order to ensure the safety and stability of the country's power system. The proposed MIC Trust Fund activity is expected to result in the formulation of these requirements.
There are two benefits for this proposed MICTAF project. First, the development of clean energy reduces Egypt's carbon footprint and contribute to the international agenda on climate change. Egypt has been proactive in demonstrating its willingness to cooperate with the international community in this area. The international community has been in turn supportive of Egypt's efforts as indicated in the financial and technical cooperation in various power projects. Second, the Bank has recently positioned itself to become a reliable leader in promoting clean energy investments in Africa. The Bank's Board of Directors, in quick succession, approved strategic legal frameworks, programs and funding mechanisms that reflect the urgency of the climate-related crisis facing the world in general and Africa in particular. In recognition of the Bank's active role in dealing with the ongoing climate issues, the AfDB President, has been recently appointed to the High-Level Advisory Group on climate change by the UN Secretary General. To further support the emergence and development of clean energy in Africa the Bank is interested in drawing lessons from the most successful experiences on the continent for the benefit of its member countries. In this context Egypt's case could serve as a reference and example to follow for other African countries and Bank clients. Therefore, the proposed MIC Trust Fund activity will help Egypt to implement its ambitious wind development program while the results of such development could provide lessons for other countries in the region. Finally, the proposed MIC Trust Fund activity is a product of the current Bank dialogue in Egypt and thereby complements the Bank's current and planned energy operations. The Bank is interested in supporting the clean energy agenda and is considering to finance a 200 MW wind power plant in a public-private venture and in collaboration with the Clean Technology Fund and the International Finance Corporation. The Bank's energy strategy also emphasizes the integration of energy systems and cross-border energy trade which is indirectly supported by the proposed MIC activity.
The project will help Egypt achieve its ambitious plan to increase the share of renewable energy to 20% by 2020 comprising the installation of 7200 MW of wind energy. The study will develop all the technical requirements for integrating the targeted wind capacity into the existing power system in Egypt in order to harness the maximum benefits from wind power while at the same time ensuring the safe and reliable operation of the national grid.
