Generating Electric Power for in-house Use
Kakira is in the fortunate position being able to generate its own electricity so that its factory is self-sufficient.
Bagasse (the fibrous residue left after sugar-cane crushing) is burnt in boilers to produce high-pressure steam. This high pressure steam is then:
The electric power used in Kakira is hence generated from a renewable biomass energy source.
In 2005, Kakira had two 20 bar steam-driven turbo-generators (3 MW + 1.5 MW) in addition to 5 diesel standby generators.
2004-2008 Expansion to Generate Electricity for Grid Supply
As part of its 2004-08 expansion, KSW installed :
The capacity of Kakira's expanded co-generation not only meets the entire increased needs of KSW's factory and infrastructure on a 24hr per day basis but also supplies up to 12 - 14 MW of electricity to the National Grid.
This project not only diversified the scope of the company's business, but also augmented its substantial contribution to the economy of South Busoga and, indeed, of Uganda.
Planned Further Expansion 2010-2012
There is a continuing deficit in electricity generation in Uganda and the national utility has undertaken emergency measures to supplement generation using diesel and heavy-fuel oil. Moreover, there is a growing demand for power in the country for development.
Considering this situation and the need to increase the renewable energy supply whilst conserving fossil fuels and reducing carbon emissions, the Madhvani Group has decided to expand its electricity co-generation capacity.
The Kakira co-generation expansion envisages installing:
The large new boiler will effectively replace the five 20 bar(a) boilers (which will be placed on stand-by for any emergency or new system break-down). Hence the bagasse burning efficiency will improve to generate steam at a pressure that is more than 3 times higher, thereby increasing its electricity generation potential.
All of the new equipment will be procured shortly and the expanded co-generation project is expected to be commissioned by July 2012, after which Kakira will supply around 32 MW electricity to the grid for 24h/d for at least 305 days each year.
