About Us

Energy projects are complex and the different development stages must be carefully thought through. Once the need for an energy generation facility has been identified, the technology options must be considered, taking into account factors such as the generation patterns required, the available space for the facility, possible environmental impacts, costs, funding options and local legislation to name but a few. Kambuku Consulting provides technical advisory services to successfully guide project developers and funders through this complex process.

project examples

Some recent projects which have been undertaken by Kambuku Consulting are described below:

Zimbabwe 20MW PV feasibility study – Kambuku Consulting analysed the project’s electrical loads to determine the viability of various energy generation options, compared to the base case
of grid electrical supply supported by diesel generation. Possible options investigated ranged from onsite solar PV with energy storage backed up with diesel generation, to various offsite IPP
options with electricity wheeled to the site. The assessment confirmed that for this project the lowest risk option was onsite solar PV with diesel generation, although the option with the most rapid delivery time was the use of an offsite solution.
