3 RURAL ELECTRIFICATION AUTHORITY (REA) Rural Electrification Authority (REA) and the Rural Electrification Fund (REF) were established through the Rural Electrification Act No. 20 of 2003 REA administers and manages the REF which it uses to implement the rural electrification program The overall mandate of REA is to provide electricity infrastructure to rural areas using appropriate technologies Rural Electrification Master Plan- Target 3.1% to 51% by the year 2030 REA has subsidy provisions for providing support to promoters of renewable energy based projects 3

4 TECHNOLOGIES EMPLOYED BY REA REA has been creating electrification infrastructure in rural areas using various technologies. The technologies used by REA to implement the rural electrification projects include:- Grid Extension Mini hydropower Development Solar energy Biomass Wind The Authority is focussing more on projects that are adding to power generation capacity of Zambia to help meet the increasing demand for electricity. 4

Project scheduled for completion in December The feasibility study and engineering design was completed in However, the site is not economically viable 6

7 EU FUNDED PROJECT EUROPEAN UNION CAPACITY BUILDING AND DEMONSTRATION PROJECT The financial agreement is meant to support the Zambia energy sector: Increase Access to Electricity and Renewable Energy Production (IAEREP) The overall objective is to increase access to clean, reliable and affordable energy and promote renewable energy production and energy efficiency in Zambia. This will be achieved through: Support to policy legal and regulatory framework for renewable. Support for feasibility study and development of demonstration projects. 7

8 EU FUNDED PROJECT REA through the European Union has received funds towards the undertaking of Pre-feasibility studies and demonstration projects. (1 hydro sites, 2 hybrid 2 SHS & 2 mini grids under EU). The project will among others help in the formulation of a Framework and Master Plan for Mini Hydropower Development which will be an input to the policy guidelines on the mini hydro development in Zambia in line with REA s Mini hydropower Development. Once the Framework is concluded, it will provide an enabling environment in exploiting the many undeveloped sites in the country and subsequently contribute to the development of the energy sector and promotion of industrial development. 8

9 REA-KASANJIKU MINI HYDRO POWER GENERATION REA is developing a 640kW Kasanjiku Mini Hydropower Station project on the Kasanjiku Falls. The project site is located on the Kasanjiku River in Mwinilunga District, North Western Province. The project work involves the construction of a 640kW (2x320kW) surface Hydropower Station, Concrete Weir with a Central Spillway, a Power Canal, a Fore-bay, a Penstock, Turbine Generator set, 33kV Switchyard and 20km long of 33kV overhead transmission line to Luwi Hospital with supporting infrastructure which includes access road, multi-facility building and staff houses. 9

10 KASANJIKU MINI HYDRO POWER GENERATION The project is being implemented by the National Research Institute for Rural Electrification (NRIRE)/CCC Engineering Limited/HNAC Technology/ Eltech Investments Limited in Joint Venture. The project which commenced on 21 st December 2015 is expected to be completed by 20 th December 2018). The 10km gravel finish access road together with bridge Structures and Drainage systems have been completed. The construction of the weir, water canal, forebay, power house and switchyard had been completed. All major equipment had been installed and the contractor was making final touches in readiness for technical commissioning scheduled for end of November

18 CHALLENGES The development of these projects comes with its own challenges which include but not limited to financing and inadequate regulatory framework. High cost of developing mini-grids REA has to provide a capital subsidy. Due to the high cost and specialised knowledge required there is need to partner with institutions involved in RE technologies for purposes of building capacity. Thereisneedtohaveanchorloadscapableofpayinga cost reflective tariffs to meet the costs of operation and maintenance of mini-grids. Private sector is more interested in on-grid renewable energy projects. 18

19 OPPORTUNITIES The regulatory framework was being addressed by various consultancies engaged under the EU and UNDP. The development of hydropower presents an opportunity to industrial development in Zambia and Africa as a whole as the role electricity plays in industrial development can not be over emphasized. Development of Mini-hydro framework. Government should encourage local manufacturing of equipment for renewable energy technology in order to reduce initial investment cost and promote sustainability. 19

20 CONCLUSION REA remains committed to its mandate of providing electricity infrastructure to rural areas of Zambia by using appropriate technologies demonstrated by the successful implementation of the first ever Mini Hydropower Plant which is nearing completion. Further, REA will continue to conduct feasibility studies and develop more hydropower sites in a quest to uplift the living standards of rural people through provision of electricity infrastructure. Industrial development will thus be facilitated through the same provision of electricity infrastructure in the rural areas. 20
