Biogas Plant in Kenya – A Custom-Made Plant Layout
Biogas Plant Overview
•
The biogas plant is build on the premises of the largest producer and
exporter of processed food (fruits, beverages, etc.) in Kenya.
•
The biogas plant will have an installed capacity of nearly 5 MWel.
•
The biogas plant uses waste from the food processing and field waste as a
substrate.
•
This specific waste (e.g. pineapple) is not used as a substrate as of now.
agriKomp tested the substrate with very good results in terms of biogas
standard volume and organic dry substance (ODS) figures.
•
The biogas plant will have four digesters and 2 post-digesters and will
roughly produce more than 21,000,000 m³ of biogas per year.
The planned biogas plant will be largest biogas plant in Africa so far

Biogas Plant in Kenya – Products
Products
The biogas plant is designed to meet the specific demands of the food-processing company (main customer). Thus, the biogas plant will also
produce steam for the food processing.
Electricity:
• The biogas plant produces electricity which will meet the main customers total demand.
• The rest will be fed into the national grid (Kenya Power) at the FiT scheme of 2012 (currently 10UScents/kWh).
Biogas as Biofuel:
• Because of the food processing the main customer needs a very significant amount of steam which is currently generated by burning
fossil fuels. Here, the biogas plant will provide biogas which will be burned in a dual-fuel burner.
Steam:
• Besides the biogas which will be used as biofuel, the biogas plant will produce steam out of exhaust heat from the CHP generators. In
total, approx. 50% of steam will be provided by the biogas plant.
Fertilizer:
• The biogas plants will produce effluent, both liquid and solid, which is rich in nutrients. This will be sold to the market.
Certified Emission Reductions (CER):
• The project is already registered under the Kyoto Protocol/Clean Development Mechanism and will generate CERs which can be sold in
the market.
The planned biogas plant will cover the total electricity demand of the food processing
company and will feed-in the rest into the grid under the FIT scheme of 2012

Biogas Plant in Kenya – Discussions with Customers
Food-Processing Company
Kenya Power (KPLC)
•
•
The Feed-in-Tariff process was started by submitting the EOI –
the Expression of Interest.
•
The next steps include an evaluation of the site, the
assessment of the Feasibility Study and the Environmental
Impact Assessment Study as well as the obtaining of required
licences, etc.
•
Currently, a Power Purchase Agreement (PPA) with Kenya
Power is prepared.
•
The negotiations with Kenya Power with respect to the PPA will
commence presumably in November 2013.
A Heads-of-Terms agreement was signed which governs the
currently agreed terms, e.g. price for electricity, land lease,
sourcing of raw materials, etc.
•
The discussions with the food-processing company are
constantly ongoing and very positive.
•
The Managing Director has expressed his interest in the biogas
technology as he sees the advantages for his company, e.g.
energy cost savings,
fertilizer for agricultural use,
reputational benefits (renewable energy, Clean
Development Mechanism),
and more reliable and stable energy production.
•
The biogas plant in Kenya will have a BOOT agreement
between the parties to guarantee supply of substrate and fixed
energy costs.

Biogas Plant in Kenya – GIZ/Project Development Programme (PDP) Sub-Saharan
Africa Involvement
GIZ-PDP members acted as an intermediator between the project sponsors and
different stakeholders in Kenya, e.g. food-processing company, local property
owners and played a role in increasing the FiT scheme from 8 USD-cents/kWh to
10 USD-cents/kWh.
GIZ-PDP bore some up-front expenses, e.g. legal expenses (a.o.).
Currently, GIZ-PDP has a strong role in facilitating potential business relation with
local and international partners, e.g. financing, sourcing etc.

Biogas Plant in Kenya –
Potential in Africa – Why Africa is so exciting for us?
The energy costs in Africa are rising as many energy sources currently used are pegged to the oil/gas (fossil fuel) price.
There is a huge potential of similar agricultural companies with high energy costs in East Africa alone, e.g. flower
production, etc.
→ The planned biogas plant in Kenya is seen as a role model for the biogas technology in Africa.
The governments of many countries have expressed their strong will to support the installation of clean technologies, e.g.
wind, solar, biogas/biomass, geothermal or hydro power and will support their efforts with attractive subsidies and customfree imports of technical components.
The market for Biogas in Africa is currently not very well developed, although overall good condition for this technology
prevail. A first mover advantage with support of government backed development institutions will provide advantageous
market.
