RENEWABLE ENERGY CONCEPT FOR ZAMBIA Kabompo Gorge Hydro Power Station and Energy park HYDRO, PHOTOVOLTAIC, BIOMASS
ELECTRICITY IN ZAMBIA The production is 1,9 GW - while the demand is much higher and still increasing (Source: Ministery of Mines, Energy and Water Development) More than 90% of the power production comes from Hydro Energy The Energy Regulation Board is encouraging private investments in power generation, especially in the rural areas The national grid in Zambia only extends to some parts of the country - rural electricity is underdeveloped and based on Diesel generators Outages and Voltage drops are regularly The growth of economy is limited by the lack of Electricity
ENERGY PARK: HYDRO, BIOMASS, PHOTOVOLTAIC Energy Park includes the construction of solar- and biomass energy generation plants in North Western Province which will work in conjunction with the Kabompo hydro power plant Construction of a 10 MWp Photovoltaic Power plant and a 0.5 5 MWel Biomass generation plant near Kabompo hydro power plant
OUR CONGLUTIONS Electricity from sun and biomass could be very attractive in Zambia but will cost more than the current price of electricity. This will change in the future as cost of conventional energy will increase (+ 48% compared 2011 to 2004). Electricity from Plant Oil or Bio Mass can be attractive, but a regulation for the combustible material is needed in case Government will decide to support energy out of CHPs (this form or energy was mentioned on the Zambian Gov. Road map). We estimate a potential for approx. 100 CHPs as a supplement to existing power generation and coming solar power sources. Renewable Energy plants can be financed by the Government - or by private investors if a feed-in-tariff or a PPA (power purchase agreement) is guaranteed long term. Private investment can be secured by the Government or by public banks, e.g. World Bank, African Development Bank.
PHOTOVOLTAIC PARK Planned 10 MWp Photovoltaic Park Land usage approx. 18-20 hectars Option is to use floating pontons on water surface Electricity output in Zambia 1,600-1,800 kwp/kwp and year 18 Million kwh production per year 450 Million kwh lifetime production Lifetime saving total 3 Billion kg CO 2
BIOMASS WOODGAS CONCEPT German car after World War II driven with wood gas up to the early fifties At that time fuel was in short supply 3 kg wood delivered power as 1 liter fuel Wood was available and so many cars were remodeled to wood gas consumption Nowadays technology is on a higher level and can be used at each place in the world where waste-wood is available Modular cascaded 40 foot container-size possible easy transport
WHAT IS WOOD GAS? Wood gas is a syntheticgas which can be used to run standard Diesel generators to produce electricity The heating value of wood is typically 15-18 MJ/kg 1.000 kg of wood can substitute 365 l of Diesel A wood gasifier burns wood incompletely in a fire box, producing solid ashes and soot and wood gas The wood gas can then be filtered for tars and soot/ash particles, cooled and directed to an engine
ECONOMIC FEASIBILITY 400 KW BIOMASS Plant with 400 kwel producing in 7,500 h per year 2. 7 Mio kwh electricity Total Invest is 1,9 Million USD Fuel consumption is 2,550 tons of wood per year Kabompo wood will remain approx. 25 years Diesel equivalent would need 750,000 l Diesel worth 1.42 Million USD per year
BIOMASS WOODGAS CONCEPT Total Area 35 km 2 of land available Timber volume is estimated to 110.000 m 3 Usage of wood for building materials/furniture industry due to high transport cost not possible Available bio mass will run a 5 MW-plant for about 3 years Phase I: Camp and Construction supply (asap) Phase II: feed-to-grid (next 9 month) It is foreseen to expand the project with plantation of fast-growing wood to increase the burning material Scalable wood gas production machinery (size 125 500kWel) is recommended, up to 5 MWel total capacity Machinery can be downsized and relocated if necessary
