What defines the sector
The energy industry is asset-heavy, highly regulated and divided by labour. Generation, transport, distribution, metering and sales are split across distinct market roles — and each role brings its own processes, data models and supervisory obligations.
The main actors are generators, transmission and distribution network operators, metering point operators, suppliers, energy traders and balance-group managers. Market communication has run for two decades over standardised message formats (UTILMD, MSCONS, INVOIC, REMADV) — modernised since 2024 as MaKo 2024 with AS4 as the transport layer.
Supervision sits with the Federal Network Agency (BNetzA) and state regulators, complemented by the BSI for KRITIS obligations. On top: 15-minute balancing as the operational beat, smart meter rollout under MsbG, EU rules from the Clean Energy Package, German implementations like EnWG, EnFG and EEG.
Generation
Conventional, renewable, distributed — from large plants to neighbourhood PV.
Network
Transmission and distribution networks as KRITIS infrastructure, with high demands on safety and stability.
Sales
Classic tariffs, dynamic electricity prices, bundled products, neighbourhood and tenant power models.
Market roles
A utility usually plays several roles at once — balancing across role boundaries is where the complexity lives.
Current challenges
Three themes have dominated the IT landscape of the energy industry for years — and will keep dominating it for the rest of this decade.
Smart meter rollout and smart meter gateway. The MsbG mandates the gradual installation of smart metering systems. The accompanying BSI protection profile (TR-03109) is technically demanding: every gateway needs integrating, every reading log evaluating, every TAF tariff application mapping cleanly. Standard legacy systems struggle with this.
Market communication on MaKo 2024 / AS4. The switch from EDIFACT-via-mail to AS4 web services has shaken the industry. Smaller utilities and municipal energy providers in particular wrestle with the transition — from certificate management through new process diagrams to special cases for tenant power or dynamic tariffs.
Dynamic tariffs under §41a EnWG. Since 2025 suppliers must offer dynamic electricity tariffs. That requires 15-minute consumption capture, spot-price feeds (EPEX), new tariff engines and transparent customer views — all in parallel with classic fixed-price tariff business.
KRITIS and IT security. The IT-Sicherheitsgesetz 2.0 and the NIS-2 directive raise the bar on protection measures, audits, incident reporting and supply-chain risk. Utilities above the thresholds must have their ISMS audited — IT architecture decisions directly carry compliance cost.
Legacy decommissioning. Many utilities still run SAP IS-U/CRM from the late 2000s. Migrating to S/4HANA Utilities or alternative stacks is a multi-year programme that has to happen alongside live operations — and survive intermediate states where old and new systems coexist.
Why custom software
Standard software covers the common third of the energy industry cleanly — booking logic, master data, classic market communication. Differentiation lives in the other two thirds: where a utility wins or loses against its competition.
Market roles are not all the same. A pure sales operator has different needs from a distribution network operator; a municipal utility with cross-utility activities (electricity, gas, water, heat, mobility) brings a complexity that no off-the-shelf product covers. Tariff variety, sales channels, neighbourhood models, charging-infrastructure operating models — every one of these levers calls for tailored software.
Concrete examples from practice where custom components pay off:
- Tariff engine for dynamic electricity prices: spot-price feed, customer-mix steering, transparent customer view — cleanly attached to existing master data.
- MaKo adapter for special processes: tenant power, neighbourhood models, dynamic tariffs — cases the standard system doesn't cover, without modifying it.
- Smart meter data pipeline: ingest of TAF readings from the SMGW, balancing, hand-off to billing and customer portal — privacy-compliant, performant, auditable.
- Energy KRITIS cockpit: ISMS indicators, patch state, supply-chain risks in one view — bridging IT, audit and management.
Our position: we build what standard software doesn't cover — and integrate it so the existing landscape doesn't suffer. That requires not just Java or .NET expertise but an understanding of EnWG, MsbG, MaKo processes and the daily reality of an energy supplier.
