Pre-investment phase
The pre-investment phase starts with a problem or an idea, and ends in a project recommendation
It may include a range of assessments and studies, such as:– Opportunity study– Pre-feasibility study– Feasibility study
AccuracyInvestment costs
![Page 5: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/5.jpg)
slide 5/60
Opportunity study An opportunity study is an assessment to determine
whether there are opportunities for a project
For example: whether there are possible solutions for an existing problem (e.g. high energy costs, unreliable energy supply, environmental concerns)
Or, are there similar examples of success/failures
Often not a “formal” study – entrepreneurs usually take the initiative, informally discuss their problem and possible solutions with their peers and experts
Outcome is a project idea (e.g. a cogeneration project)
Sotik: completed
![Page 6: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/6.jpg)
slide 6/60
Pre-feasibility study
A pre-feasibility study is a quick assessment of the basic feasibility of a certain project idea.
It determines whether basic technical / organisational requirements are met, and whether the solution is cost effective.
Pre-feasibility studies are often executed by external experts, and have a short lead time (weeks).
The study should indicate whether or not a feasibility study is justified.
![Page 7: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/7.jpg)
slide 7/60
Feasibility study
A feasibility study is an extensive assessment of the feasibility of a certain project
Key elements include (see next slides):– Technical issues– Environmental issues– Financial feasibility– Organisational issues– Risk analyses– Financing
The feasibility study should result in a project recommendation and a bankable project document
![Page 8: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/8.jpg)
slide 8/60
Feasibility study: technical issues (1)
Technical assessments should determine which system is required, and what are the inputs and outputs
Basis for the technical assessment is an analysis of on-site processes, for example:– Determine current energy demand (heat and electricity) and
projected developments therein: energy consumption, peak demand, load profiles, steam condition requirements, etc
– Determine fuel availability and attributes (moisture, contaminants, morphology, ash content, density, calorific value)
– Integration of CHP plant to the local project site
![Page 9: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/9.jpg)
slide 9/60
Feasibility study: technical issues (2)
Technology selection, for instance:– combustion/steam cycle or gasification/engine– steam turbine or steam engine or ORC– anaerobic digestion
Technology attributes – heat and power output– efficiency– fuel requirements– fuel pretreatment– O&M requirements
![Page 10: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/10.jpg)
slide 10/60
Steam engine vs Steam turbine
Advantages Disadvantages
Steam engine Low cost at low power ratings
Robust design, long life expectancy
Good performance at lower loads
Low capacity (<200-500 kW)
Low efficiency (~6-7%)
Low temperature heat (80-90 oC)
High oil consumption
Steam turbine Higher efficiency (>10%)
Possible higher temperature heat supply
Low consumables
Higher capacity (>500 kW)
Higher cost in smaller scale
Less suitable for intermittent use
Steam engines for smaller loads, intermittent operation, at low biomass price
Steam turbines for higher loads, continuous operation, biomass may be to be bought

slide 11/60
ORC (Organic Rankine Cycle)
For instance in Ludwigsfelde, Germany– Wood-fired boiler– Wood consumption: 18700 ton/yr– 1,5 MWe, 10 MWth– 7500 hrs/yr– 86% availability– Fully remote controlled from Italy
![Page 12: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/12.jpg)
slide 12/60
Feasibility study: environmental issues
Environmental assessment should indicate to what extent the project can meet local / national environmental standards
Example:– Assessment of emission regulations (e.g. dust, NOx, SOx)– Comparison with expected (rated) emissions from systems– Determine required emission control systems (flue gas filters, de-
NOx)
Legal requirement Kenya: EIA, Environmental Impact Assessment
![Page 13: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/13.jpg)
slide 13/60
Feasibility study: environmental issues emission control [1]
Main contaminants: particles, NOx, CO
Aspects to consider – Environmental legislation– Local situation– Technological state of the art – BAT: Best Available Technology
Levels of control (and measures)– Fuel side (prevention)– Conversion side (prevention)– Flue gas side (end-of-pipe)
![Page 14: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/14.jpg)
slide 14/60
Feasibility study: environmental issuesemission control [2]
Fuel side (prevention):– moisture content, fuel size, no contaminants– quality clauses in fuel delivery contracts
Conversion side (prevention):– optimal process control (partial vs full load)– multiple air supply/staged combustion– flue gas circulation (NOx control)
Flue gas side (end-of-pipe):– particles: (multi)cyclones, fabric filters, electrostatic filters– NOx: catalytic reduction (combined with SOx)

Feasibility study: financial issues (9)
Financing– Determine financing needs (fixed investments, interest during
construction, working capital)– Determine financing mix (equity, loans, subsidies)– Risk assessment
Some general observations– Maximisation of subsidies and loans give the highest Return on
Investment, and reduces the risk for the investor– Often an iterative process, depending on the availability of equity
and loan conditions

Planning
Example– For industries, energy production is often not core business. They
may prefer to undertake such activities in a separate company. In such a company, other shareholders can be sought: e.g. biomass suppliers, utility companies or private equity companies. The industry may choose to retain a majority position (51% of the shares) in order to keep control.

slide 39/60
Recommendations (1)
Set-up an organization scheme:– taking into account the interest of all parties involved:
fuel supplier(s), operating entity of bio-energy plant, energy consumer, financing parties, authorities, technology suppliers
– identify relations and necessary agreements between parties involved (i.e. fuel delivery agreements, energy supply agreements)
– evaluate different organization models

slide 40/60
Recommendations (2)
Special attention to fuel supply: – characteristics– seasonal aspects– base price– transport (+costs)– pretreatment requirements (+costs)– storage (+costs)– contractability
Special attention to energy consumers – delivery conditions– consumption assurance– price assurance
![Page 41: The Project Cycle Presentation 2 for Sotik Tea Company Harrie Knoef 10-11 th January 2008](https://reader030.vdocument.in/reader030/viewer/2022032313/56649e685503460f94b64f26/html5/thumbnails/41.jpg)
slide 41/60
Recommendations (3)
Involve local parties and authorities in an early stage
Take into consideration all potential succes and failure factors– also seemingly less important factors– it’s better to mention and refute than not to mention at all

Feasibility results vs practice Investment tend to become higher than expected,
because of:– Delays– Too optimistic planning and cost estimate (often to secure finance
from banks)– Additional desires– Mistakes during engineering phase– New legislation on HSE, emissions, …
This results often in lack of working capital
Fuel switch and portfolio projects are very successful
