// The Challenge

Why energy providers need
an API Portal.

The energy transition, smart metering, and decentralized generation are creating a flood of interfaces — between grid operators, metering operators, generators, and regulators. Without central management, control slips away.

Version chaos in practice

Grid operations uses v2, sales is still on v1, and a utility partner integrates against an outdated spec. No shared state. No changelog. Just tickets.

Partner onboarding by word of mouth

Metering operators, energy traders, utilities — everyone needs access to different endpoints. Today that runs on Slack, spreadsheets, and goodwill. It doesn't scale.

Developers can't find APIs on their own

If you don't know an interface exists, you ask. If you ask, you block someone. If you block, you slow down. Self-Service solves this — if there's a portal.

// Use Cases

Built for the
energy sector.

Smart Metering

Manage meter data and MDM interfaces centrally.

Manage all APIs around intelligent metering systems in one place — from meter readings and load profiles to tariff switching. Metering operators and grid operators find the right interface via Self-Service.

  • Self-Service access for metering operators
  • Sandbox with simulated meter data
  • Versioning per release with automatic changelog

GET/api/v3/meters/{meterId}/status
PUT/api/v3/meters/{meterId}/config
GET/api/v3/load-profiles/daily
Grid Operations

Document and deliver grid operations APIs with controlled access.

APIs for grid control and feed-in management — centrally documented and delivered with role-based access control for the teams that need them daily.

  • Role-based access control per API and team
  • Automatic breaking-change detection
  • Complete audit trail of all changes and access

E-Mobility

Orchestrate charging infrastructure APIs and billing interfaces.

APIs for charging infrastructure, roaming, and billing — centrally documented and accessible via Self-Service for charge point operators and roaming partners.

  • Self-Service portal for roaming partners
  • Sandbox for integration testing before go-live
  • Separate environments per partner type

// Security & Operations

Built for
sensitive infrastructure.

Access control, audit trail, and flexible deployment — for teams that can't compromise on security.

Access under control

Every team, every partner, every endpoint — role-based permissions with granular configuration. No developer sees more than they should.

Complete audit trail

Every change, every access, every deploy is logged. Immutable. Traceable. For internal reviews and external audits.

On-premise available

Want to run the platform in your own infrastructure? Self-hosted deployment included — even for isolated network segments.

GDPR / GDPR

All data stays in Frankfurt. Full data sovereignty, no detours.

// API Landscape

Typical energy APIs
managed in the portal.

From meter data to grid control to e-mobility — the API Portal organizes the entire interface landscape of an energy provider.

POST /grid/feedin-management/curtail
REST CRM

Customer Portal API

Customer portal interfaces for contract management, tariff changes, consumption display, and installment adjustments.

GET /customers/{id}/contracts
POST /customers/{id}/tariff-change
REST Billing

Billing & Tariff API

Billing processes, tariff calculation, EDIFACT message generation, and receivables management.

GET /billing/invoices/{invoiceId}
POST /billing/tariffs/calculate
REST OCPP

Charging Station API

Charge point management, charging sessions, roaming integration, and real-time availability for e-mobility infrastructure.

GET /charging/stations/{stationId}/status
POST /charging/sessions/start
REST Forecast

Weather & Forecast API

Weather forecasts, generation predictions for wind and solar, and load forecasts for grid planning.

GET /weather/forecasts/{region}
GET /generation/forecast/solar/{parkId}
“With the API Portal, we've taken collaboration between grid operations, metering, sales, and 30+ utility partners to the next level. API onboarding now takes hours instead of weeks.”
Faster partner onboarding

// Architecture

Seamless integration into the energy IT landscape.

The API Portal integrates with existing energy provider systems — from ERP and billing systems to IoT platforms. CI/CD pipelines sync API specs automatically on every release.

  • ERP & billing system connectivity
  • Grid operations system connectivity
  • IoT platforms & messaging systems
  • SSO via SAML / OIDC with corporate identity
  • On-premise & air-gapped deployment

Each partner gets Self-Service access through the portal only to the APIs cleared for them. Role-based access control allows granular configuration per partner, team, and environment. Sandbox environments enable integration testing without having to ask the development team.
The API Portal supports OpenAPI 3.x for REST APIs and AsyncAPI 2.x/3.0 for event-driven architectures and MQTT-based streams. This lets you centrally document both classic request-response APIs and real-time data streams — such as meter readings or grid events.
Each API version is maintained separately in the portal — with auto-generated changelog, diff view between versions, and breaking-change detection before every deploy. Teams and partners always see the version that applies to them, while older versions remain accessible and documented.
Yes. The API Portal is available as a self-hosted deployment and can be run in your own infrastructure — including air-gapped networks without internet connectivity. Suitable for environments with elevated requirements for data residency and network segmentation.
The portal is built with multi-tenancy — every partner, region, or team can get an isolated view of the API Catalog. APIs, teams, and access rights can be managed via the portal's own API, enabling automated onboarding processes.
