What an ERP for biogas plants has to cover

ERP for biogas plants:
from the weighbridge to the invoice.

An ERP holds the commercial side of a business together: material, partners, contracts, billing. A biogas plant adds what no standard system knows about, such as silo stock, dry matter, trace elements and gas composition. Terra Flow Systems is built for exactly that combination.

“ERP” sounds like something for a corporate group, but it describes a simple principle: every process in a business sits in one data model instead of in several programs that know nothing about each other. The benefit does not come from the individual program. It comes from the points where two things meet, the weighing with the contract, the silo stock with the feeding, the gas reading with the feedstock it came from.

In the biogas industry that meeting still happens mostly in the plant manager’s head. The weighbridge prints slips, the stock sits in Excel, the contracts are in a folder, the gas analysis shows its readings on its own screen. Any evaluation that reaches beyond one of those sources is manual work, and therefore rare.

Six areas decide whether a system is any use in a biogas plant. What is written about TFS underneath each of them is part of the packages today. Nothing there is an announcement.

01

Taking in feedstock and weighing it

Every delivery needs a gross weight, a tare, a net figure, a supplier, a contract and a feedstock type, recorded in the moment the vehicle stands on the weighbridge and not in the evening from a pile of slips.

In TFS

The Performance Cube reads the weight straight from the weighbridge terminal. More than a dozen protocols for common terminals are built in; Pfreundt wheel loader scales come in through their own interface and do not need the Cube. The status light at the weighbridge is switched by the Cube itself.

02

Keeping storage and batches

What is in which silo, how long will it last, where did it come from? Without reliable stock figures, purchasing turns into guesswork and traceability into a search through files.

In TFS

Every batch gets a digital identity with origin, dry matter, trace elements and storage location. Storage management is included from the Basic package onwards, and the trace element management grows with the package.

03

Managing suppliers and contracts

Quantities, prices, terms and commitments for each supplier. Beyond a handful of partners this is the point where a spreadsheet stops carrying the load.

In TFS

Digital contract management from Advanced onwards. The Premium package adds a managing portal in which partners and suppliers look up their own weighings, which takes the follow-up calls out of the office.

04

Billing

Deliveries turn into credit notes and invoices. Anyone who types up the weighing slips for that pays for digitalisation twice: once in time, once in typing errors.

In TFS

Weighing, contract and price hang together in the system, and invoices come out of that automatically. The fertiliser product balance runs from the same data.

05

Bringing process data in

Gas composition, dry matter, CHP load: figures that sit in the plant control system and are missing on the commercial side. Kept apart, they cannot be set against each other.

In TFS

Gas analysis and sensors come in the same way as the weighbridge, through Awite systems and through control systems over Modbus, OPC UA or S7. In the Premium package gas readings are correlated with the feedstock input.

06

Records and evaluation

Certification, the operating logbook, figures for the bank. All of it is an evaluation of the same data, provided the data sits in one place.

In TFS

Dashboards and KPI management, freely configurable in the Premium package. The operating data is held on Austrian servers.

How TFS gets into an existing plant

The connection to the plant is handled by the Performance Cube, a small computer that we send out ready configured. Put it down, plug in power and internet, done; from then on it reads weights at the terminal and sends them to TFS encrypted. A day after unpacking at the latest, the plant runs digitally. The Advanced and Premium packages include a Cube.

On the security side, the Cube opens the connection outwards. Not a single port has to stand open in the plant network. The operating data is held on Austrian servers.

Which package suits a plant depends on its size, the number of suppliers, the number of sites and on whether a gas analysis is in place. The software advisor asks about that in nine questions and writes down why the recommendation turns out the way it does.
