Prefeasibility studies
Assess the viability of an energy project before committing to detailed studies
Contact usInformed investment decisions from the earliest stage
Our prefeasibility studies give project developers, funders and public authorities a clear, quantified view of a project’s potential. They rely on qualified data and a documented method, so that every conclusion can be checked.
Our studies help your teams:
- Rule out sites and configurations that do not hold up, early on
- Compare several options on a common, transparent basis
- Quantify energy yield and costs with their uncertainty
- Give funders a sourced, verifiable file
Backed by our knowledge of West African energy data, our studies reduce the risk of later phases and speed up decisions.
-
Solar plants, mini-grids, hybrid systems and solar pumping
-
From a single site to a site portfolio and a national programme
-
Sourced assumptions and quantified uncertainty
Reduce risk before detailed studies
A sound prefeasibility study avoids commissioning in-depth studies for a project that cannot succeed. It brings out, from the start, the factors that decide its success: resource, site constraints and cost level.
With our studies, you can:
- Identify the factors that determine the project’s success
- Focus the study budget on the strongest options
- Prepare the terms of reference for the detailed feasibility study
Compare options on a common basis
Sites, technologies and system sizes are assessed with the same data, assumptions and method. Differences between options then come from the project itself.
The study lets you:
- Rank candidate sites by potential
- Compare PV alone, hybridisation and storage
- Measure the project’s sensitivity to key assumptions
A file your funders can verify
Every input points to its source and a dated release. Energy yield is given as P50 and P90, and every economic assumption is listed.
The file presents:
- Solar resource from series calibrated on ground measurements, where available
- Energy yield, investment costs and levelised cost of energy
- Identified risks and our recommendations for next steps

Presentation
We present the results and deliver the report, with our recommendations.
Frequently asked questions
What is the difference between prefeasibility and feasibility?
Prefeasibility establishes whether a project is worth pursuing and which options to keep. The detailed feasibility study follows, on the selected option, with in-depth field studies.
Which countries do you work in?
Across West Africa. In Guinea, our studies rely on series calibrated on ground measurements. Elsewhere, they use satellite products with documented uncertainty.
How long does a study take?
It depends on the number of sites and options studied. It is set at scoping, together with the scope and price.
Can you use our own data?
Yes. Measurements, records or bills you provide are integrated and qualified in the same way as our data.
Are the results kept confidential?
Yes. A study carried out for a client belongs to that client and is not published.
