Data scattered, rebuilt for every buyer
Production information sits across monitoring systems, reports and files. Each counterparty asks for it again, in its own shape, and somebody assembles it again by hand.
For producers
Wattstamp is being built to turn production data from your plant into a clear, reusable record.
The difference
Today
Production information sits across monitoring systems, reports and files. Each counterparty asks for it again, in its own shape, and somebody assembles it again by hand.
With Wattstamp
One connection at the source becomes one verified record. The same record answers the certifier, the buyer, the bank and the auditor, without being rebuilt for each of them.
Zero friction
We start from the information your plant already generates. Understand your production, organise the evidence behind it and explore how that information could support conversations with buyers, certifiers and financial partners.
That information often sits across monitoring systems, reports and files. Wattstamp’s approach brings it into a common structure, so it can be understood and reused more easily.
We connect to the plant and the systems you already run.
Market participants pay for the data services they use.If a separate service or future programme is proposed, its scope and any fees will be set out before you choose to take part.
What you get
01
A continuous view of how your plant is producing, from the systems you already run.
02
A checked, structured history of your production that you can show to anyone who asks.
03
The evidence prepared in the hourly detail a granular certificate needs.
04
A track record a financing conversation can start from, as those services become available.
Granular Certificates
Your renewable energy has a location, a source and a time of production. Granular Certificates make that detail visible, recording electricity generation in hourly or shorter intervals and helping buyers match their consumption with renewable production during the same period.
For producers, this opens a path to buyers who value when and where electricity is generated, alongside its renewable origin.
Traditional GO
One total for the whole period.
Granular certificate
Every hour visible, in its own right.
What a traditional GO is worth
€0.64–0.70per certificate — and one certificate covers a whole MWh

Wattstamp is building the data foundation for that access. By collecting, checking and organising production data, we aim to help producers prepare the evidence required for granular certification and share it with participating issuers and market partners.
Show how your plant generates throughout the day, beyond aggregate production volumes.
Turn available metering data into structured records that can support an issuer’s assessment.
Future opportunities
A better production record can support the assessment of opportunities involving energy purchasing, certification, financing or other market services, as these become available.
Each opportunity has its own requirements. A record supports the assessment; it does not guarantee acceptance, financing or additional income.
From your plant to the Vault
The Vault
01
Your verified production is what backs it. Access expansion capital based on what your plant actually produces, not on months of paperwork.
02
Every verified MWh adds to your history. After a period of verified production, you can open a financing request:like showing your payslips before a mortgage.
03
Once your contract is in the Vault, its terms run on your verified data: what you produce, what is due, when it is paid.
04
You bring a mandate on your data and contracts, not your asset. Your plant and your business remain yours.
Onboarding
Share the location, generation technology and the systems you currently use to monitor production. If you manage several plants, we can discuss the portfolio together.
We look at how your production information can be accessed through existing systems or available records. The aim is to use the infrastructure you already have, without requiring new hardware.
Before a connection is made, we define the data involved, the access required and the permitted uses. Any proposed sharing with market participants should be clear from the start.
The data is organised and checked so that the source, production period and quantity can be understood together. From that foundation, we can assess which uses are relevant to your plant.
