This feasibility study was carried out at Mweiga Blooms Ltd in order to identify various Alternative Energy
Sources (AESs) at the facility and with a main focus of a solar PV system on the upper farm.
One (1) AESs was identified as the ground mounted solar PV system, this was due to availability of a large
tract of land which will be rolled out in phases. Other than the alternative sources of energy, we
recommended other energy conservation measures, the practice of using more energy efficient systems
in the facility was to reduce further the energy consumption on the farm, when the farm is in operation.
Energy conservation measures (ECMs) are considered here because the cleanest and cheapest energy
source is the energy that is used.
From the outlined recommendations on the energy efficiency system and renewable energy technologies
we have a draft investment plan phased our as follows:
? AES 1 – Energy conservation measures (ECMs) – To be implemented in phases with Lighting and
High Efficiency Motors (HEMs) within the Year 1 of operation resumption and Variable frequency
drives on Year 2 of facility operations resumption
? AES 2 – Solar PV system - To be implemented one year after the study that’s January 2020, thus
allows other regulation fulfillment such as licenses and negotiations for Phase 1 (3,000 kWp).
Phase 2 that’s 13,701 kWp system be rolled out in 2022
Techno economic analysis was done for the solar PV system to ascertain their viability for implementation
at the facility. The following is a summary of the AESs studied;
1. AES1 - Energy Conservation Measures(ECMs) - this is the cheapest and the cleanest energy source.
Once implemented, ECMs have the ability to reduce energy consumption in the facility hence a
reduction in the operating expenses of the facility.
Implementation of the ECMs should be the first step when it comes to installation of a new power
generation plant because it can significantly reduce the size and consequently the cost of
constructing a power plant. ECMs can reduce the size of a power plant that is to be constructed,
thus in itself is an energy source.
In this study the following ECMs were identified and analyzed to assess their impact on energy
consumption at the facility.
a) Lighting Upgrade- This will involve replacement of all fluorescent high efficiency LED lights
which can save over 60% of lighting energy in the facility.
b) Replacing standard efficiency motors with high efficiency motors - Energy constitutes to the
highest percentage of Life Cycle Costs of a motor; approximately 95%. Thus, a high efficiency motor reduces the Life Cycle Costs of a motor. A high efficiency motor can save up to 5% of
the energy compared to standard motors.
c) Installation of Variable Frequency Drives(VFDs) on all the pumps. The pump motors are running
at 100% during the facility runtime. With VFDs, the motor speed is matched to the flow as per
affinity laws hence leading to energy savings. Motor speed is dependent on load.
A survey of agro-industries (outside the sugar sector) that are currently generating their
own heat and power from agricultural waste or deploying other renewable energy
technologies such as biogas, solar and small hydro show that the installed generation
capacity of most is in the order of less than 1 MW with only a handful of tea companies and
flower processing enterprises using 2-3MWs. The report is organised in the following fashion: the first two sections present an overview
of the energy and key agro-industrial sectors in Kenya, respectively. The third section,
examines each selected agro-industrial sector with the objective of assessing its ability to convert its agricultural residues to green energy or to deploy other renewable energy
technologies. Based on a review of each sector’s production history and trend, prevailing
organisational structure, energy needs and use, the study discusses relevant clean energy
options. The fourth section discusses opportunities available for agro-industries to expand
clean energy deployment and identify key barriers to harnessing the significant clean energy
resources available to agro-industries.
By assessing four main agro-industrial sectors as well as reviewing past and recent policy
developments in the energy sector, this report has identified key stakeholders, their
interests as well as possible barriers to engaging in clean energy production in their
respective sectors. It contributes to strengthening a foundational understanding of the
influencing factors, the motivation as well as constraints that impede agro-industries from
participating or scaling up their capacity in clean energy production. The report also
observes that sectors that have managed to retain their share of the global market i.e tea
and horticulture - driven by the need to cut costs and ensure reliable supply -have
registered encouraging success in utilising their agricultural waste and deploying renewable
energy technologies. With more direct support and better cross-agencies coordination, the
Government can create a conducive environment to support and scale-up agro-based clean
