Dinson Iron and Steel Company has recently unveiled a significant 50MW power plant at its Manhize Steel Plant, marking a pivotal step towards energy self-sufficiency. This new facility is designed to decrease the company’s dependence on Zimbabwe’s national power grid, which has been characterized by frequent outages and supply challenges. The launch was attended by Energy and Power Development Minister Edgar Moyo, along with other senior government officials, who highlighted the importance of this initiative for the nation’s energy landscape.
Currently, the Manhize Steel Plant operates with a consumption of approximately 28MW. The power plant not only meets this demand but also aims to synchronize the excess capacity back into the national grid, providing additional electricity to the Zimbabwe Electricity Transmission and Distribution Company. Minister Moyo expressed his enthusiasm about the project, stating that the plant's energy generation capacity could significantly contribute to alleviating the power supply gap in the region.
The project director at Dinson, Wilfred Motsi, noted that while the facility can generate up to 50MW, current usage is around 24MW due to ongoing construction. Plans are already in motion to further expand the power generation capabilities with an additional 20MW installation, which would bring the total output to 70MW. This expansion underscores Disco Steel's commitment to enhancing its operational efficiency while also supporting the national grid.
A key feature of the new power plant is its use of advanced heat exchange technology. The power generation process begins with coal combustion in a Circulating Fluidized Bed boiler, renowned for its high efficiency and low emissions. The heat generated from the combustion process is utilized to produce high-pressure steam, which then drives turbines to generate electricity. This method not only optimizes energy production but also minimizes maintenance costs.
Additionally, the plant captures waste heat and combustible gases produced by the blast furnace and Basic Oxygen Furnace. By harnessing these waste products, Disco Steel significantly reduces its carbon footprint and environmental impact. This innovative approach not only promotes sustainability but also aligns with global trends towards greener industrial practices.
Minister Moyo encouraged other energy-intensive industries to emulate Disco Steel’s initiative by investing in their own power generation solutions. By doing so, companies can not only lower their operational costs but also play a crucial role in bridging the persistent energy supply-demand gap in Zimbabwe.
