High-volume data processing
The programme required scalable processing of large half-hourly consumption datasets.
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.
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.
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
The first production-ready version was delivered, with continued support for rollout, fixes, feature expansion, and future regulatory change.
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.
Telemetry, tracing, dashboards, and alerting improved troubleshooting, incident analysis, and performance optimization.
"Our partnership with Clever Grapes over the past few months has been extremely positive. Their team is flexible, adapting swiftly to our changing needs in the fast-paced energy industry. Communication has been exemplary, with frequent updates and swift responses to our feedback. Their ability to act quickly without compromising on quality has made a real difference to our operations. As we look forward to further progress and the implementation of future processes, we are confident in Clever Grapes' ability to deliver high-value results."
