Connected commercial-energy intelligence

Every record connected to the work it should trigger.

Commercial energy information is often divided between supplier portals, bills, spreadsheets, inboxes and contract folders. Dernetz brings that information together and uses Joji AI to help organise, prioritise and prepare the work around it.

Joji AI

AI assistance with human review built in.

Dernetz’s built-in AI assistant supports bill and document processing, account research, missing-information checks and next-step guidance, while human users retain oversight and approval.

Technology prepares the intelligence. People control the commercial decision.

Joji prepares information for review; experienced people decide what happens next.

AI at utility-estate scale

Built for complexity that cannot be managed in another spreadsheet.

Data centres, industrial operations and large estates can generate extensive meter information, half-hourly data, bills, contracts, supplier communication and open commercial actions. Dernetz keeps the operating record connected so important priorities do not disappear inside the volume.

Complexity grows. The operating record stays connected.

Real commercial applications

One operating system. Every part of the commercial-energy lifecycle.

Procurement, bill validation, metering support, supplier disputes and renewal planning are applications of the connected operating model rather than the whole proposition.

Start with one bill. Build the account picture from there.

A bill can provide the first information required to connect the site, supply, meter, charges and supplier account. Further bills, contracts, usage data or supplier records may be required for a complete review.
