Sites that are hard to qualify
When the project is still vague, full of assumptions or hinging on constraints to be understood before spending time and capital.
Vertical RES advisory
We turn RES sites, documents and opportunities into clear, defensible and bankable decisions.
Big 5 Energy supports developers, investors, EPCs and industrial operators with specialist advisory on Site Intelligence and documentary / full-spectrum Due Diligence.
The problems we solve
When a project is promising, but not yet legible.
Many energy projects look good on paper, but turn fragile once you get into constraints, grid, layout, documents, contracts and underlying assumptions. Our job is to give shape to that complexity and surface right away what holds up, what needs deeper analysis and what should be stopped.
Data rooms to read and organise
When the documentation exists, but it is scattered, misaligned or hard to translate into a clear position.
Deals to reduce to negotiable terms
When the deal can move forward only if risks are isolated, described and brought back to concrete terms.
Decisions to defend before third parties
When you need a reading that an engineer, an investor or a lender can use without ambiguity.
The two services
Two services, two levels of decision.
Site Intelligence to qualify an opportunity. Documentary / full-spectrum Due Diligence to read a dossier or a data room and understand what you are really buying.
Site Intelligence
Analysis of the site and its context
To understand whether an opportunity is worth developing, exploring further or discarding.
- Qualifies a site before committing resources.
- Reduces risk in the early stages of the process.
- Produces a first, well-founded decision.
Documentary / full-spectrum Due Diligence
Multidimensional analysis of a dossier or a data room
To understand what you are really buying, what the risks are and on what terms to proceed.
- Reads and organises the available documentation.
- Surfaces risks, gaps and material conditions.
- Supports acquisitions, financing and closing.
The method
Method, priority, depth.
We do not work by piling up documents, but by hierarchy of risk. We start from the problem driving the decision, ordering the sources, defining the critical points and producing an output the client can use in development, negotiation or investment.
- 01
Framing
We start from the right question, the real perimeter and the client’s decision point.
- 02
Ordered reading
We separate data, assumptions and risks. We organise the useful material and discard the noise.
- 03
Defensible synthesis
Every output must help to decide, not just to describe. The recommendation is always explicit.
- 04
Clear escalation
If the project requires a deeper level, we say so immediately and propose the next step.
Why Big 5 Energy
A vertical advisory, not generalist consulting.
Big 5 Energy is built for those who must move in a complex market, where value lies not in owning data but in the ability to interpret it well. Our advantage is combining territorial reading, documentary logic and deal orientation in a single workflow.
Specific focus on the RES world
We work on sites, projects and data rooms with a vertical specialisation, not a generalist logic.
Outputs legible to engineers and decision-makers
Our analyses serve both those who must go into technical detail and those who must make an investment decision.
Fit for development, investment and closing
The same working structure holds across different phases of the process, from first qualification to closing.
Clear language, not simplified
The reading is ordered and concrete, but not flattened. The client understands what matters and why.
