Investment-grade due diligence for distributed energy assets

Lumen reads every document in a project’s data room, runs codified technical, legal and commercial checks, and puts every finding in one register. Full diligence in days, not weeks, at a price small projects can carry.

The Lumen register for a demo project: findings grouped into discrepancies, issues, risks and assumptions, with one finding open showing its evidence documents and history.
The register on Lumen’s demo project. Every risk, issue and discrepancy is linked to the documents behind it.

On a small project, diligence costs four times more as a share of capex

A rooftop needs the same review as a solar farm. The project pack runs to about 100 documents whether the asset is 200 kWp or 20 MW, and consultants read every one by hand.

So most small projects go without. Only 8% of projects under £250k are formally diligenced, and without diligence they can’t reach third-party capital.

Full diligence, with nothing sampled to fit the fee

  • Every document, nothing sampled

    Every file in the data room is read start to finish. On average, 2,000+ variables per project go into one structured record, each cited to its source.

  • Codified engineering checks

    Checks written by engineers who have diligenced these assets, not prompted from a general AI model. They run as versioned rules on every project.

  • One register, signed off

    Every risk, issue and discrepancy sits in one shared list, linked to its evidence, with a full audit trail. PI-backed engineer sign-off when the deal needs it.

Tested against a manual review on a live UK project

Same scope, same data room. The client’s engineers confirmed the findings.

  • 100+documents in the data room, every one read start to finish
  • 4,000+variables extracted, cited to source and cross-checked against each other
  • 32register items raised and confirmed relevant by the client’s engineers
