Case Study

Engineering support for MHHS data processing platform delivery

Engineering support for Energy Assets across MHHS data processing, DIP integration, observability, and testing capabilities.

Energy Assets

Our Client

Energy Assets is one of the UK's leading independent metering and utility services providers, operating across smart metering, energy data services, and network operations. Clever Grapes joined the MHHS transformation programme in May 2023, scaling from 2 to 9 engineers while contributing across selected data processing, integration, observability, and testing capabilities.

The Challenge

MHHS required scalable processing of half-hourly consumption data across complex market flows.

Energy Assets needed engineering support across MHHS-related data processing capabilities, including ingestion from multiple sources, validation and aggregation of half-hourly readings, complex MPAN and meter relationships, missing-data estimation, secure DIP integration, and operational traceability across distributed services.

High-volume data processing

The programme required scalable processing of large half-hourly consumption datasets.

Complex market logic

MPAN and meter relationships, time-based rules, retrospective corrections, and missing-data estimation added significant complexity.

Secure DIP integration

The platform needed secure integration with DIP using certificate-based authentication and mTLS communication flows.

Operational traceability

Distributed processing needed monitoring, traceability, and reliable troubleshooting across services.

The Solution

Engineering contribution across cloud-native MHHS platform capabilities

Clever Grapes engineers contributed to the design, implementation, testing, performance validation, and scalability of MHHS-related platform components, working across distributed processing, secure integration, observability, and test tooling inside the Energy Assets programme.

Large-scale settlement processing

Supported half-hourly consumption aggregation, validation workflows, message orchestration, retries, retrospective corrections, and missing-data estimation for settlement-ready processing.

Multi-tenant retrieval services

Helped shape a retrieval layer that can operate as a shared service across multiple organisations and metering ecosystems, supporting API-based integrations and onboarding of additional external consumers.

Secure DIP integration

Contributed to secure Data Integration Platform communication using certificate-based authentication and mTLS patterns.

Observability and telemetry

Helped improve operational visibility with tracing, logs, metrics, dashboards, and alerting across distributed services.

Custom MHHS testing platform

Supported tooling for reusable request collections, workflow validation, integration testing, and audit history.

Business Outcomes

Production-ready MHHS capabilities

The first production-ready version was delivered, with continued support for rollout, fixes, feature expansion, and future regulatory change.

Large-scale data processing

The platform supports high-frequency half-hourly consumption processing across large metering datasets, with architecture shaped around long-term scaling ambitions of up to approximately 500,000 meters.

Improved operational visibility

Telemetry, tracing, dashboards, and alerting improved troubleshooting, incident analysis, and performance optimization.
