Software testing for energy utilities

Grid control, smart metering, market communication – energy IT is critical infrastructure. Outages and defects have consequences far beyond IT.

Typical challenges

Critical infrastructure (KRITIS/NIS2, BSIG) with the highest availability and security demands.
Grid control and metering systems, smart meter gateways and their secure integration.
Market communication (EDIFACT / EDI@Energy) with regular format changes on fixed dates.
Energy-transition projects: new processes, redispatch, dynamic tariffs.

Regulation & standards

IT Security Act 2.0 and BSI-KritisV, the IT security catalogueue under §11 EnWG (BNetzA), ISO/IEC 27001/27019 and BSI TR-03109 (smart meter gateway). We test with evidence that withstands these audits.

Testing focus in the energy sector

Market communication: GPKE/MaBiS processes, EDIFACT messages and deadline logic – test cases along market roles rather than system boundaries.
Smart meters and gateway integration: Meter readings, time series and reading windows; verification of measurement processing and plausibility checks under realistic data volumes.
Billing and grid fees: Periodic and final invoices across tariff changes, price adjustments and retroactive corrections.
Control systems: Separating OT and IT, testing in environments with critical-infrastructure constraints and restricted access.

Typical starting point

We usually find a landscape of standard software, in-house development and market partner interfaces in which nobody tests the deadline logic end to end. The fastest win lies in automated checks of market communication – that is where the defects arise that later have to be cleared up manually.
