Cumulative Impact Assessment for five Hydropower Projects (2MW, 41MW, 9MW, 67MW, 9MW)
ARPE Limited (which consists of shareholders, Berkeley Energy, through the African Renewable Energy Fund (AREF), and PAC S.p.A – an Italian Engineering firm), was developing a cascade of five hydropower projects: HPP-1, HPP-2, HPP-3, HPP-4 and HPP-5 of varying capacities, along River Achwa and River Agago in the districts of Gulu and Pader, in Northern Uganda. Development of this cascade of five hydropower projects had potential to cause a number of cumulative impacts, and it is upon this background that ARPE Limited contracted Atacama Consulting to undertake the Cumulative Impact Assessment (CIA) of the five planned hydropower projects.
The CIA describes the combined impacts of the proposed hydropower projects, how they interact with other existing and realistically predictable future projects, and the external environment and social drivers to produce a cumulative effect. The CIA built upon the assessment of the direct and indirect impacts identified in each of the project specific Environment and Social Impact Assessments (ESIAs).
The CIA was developed under the guidance of the International Finance Corporation’s (IFC’s) Draft (External Peer Review) – CIA Guidance Note for Private Sector in Emerging Markets, and IFC Performance Standard 1 (Assessment and Management of Environmental and Social Risks and Impacts).
