Microservices Architecture for UK CleanTech — Ofgem Built In

Energy Data Microservices Architecture

UK CleanTech microservices decompose naturally by energy data domains. Recommended domain boundaries: (1) Meter Data Service (smart meter data ingestion — AWS IoT Core, DCC integration, half-hourly HH data), (2) Generation Service (renewable generation data — SCADA, REGO generation, grid export), (3) Carbon Calculation Service (Scope 1/2/3 calculation — DEFRA emission factors, SECR reporting), (4) Tariff and Settlement Service (energy tariff, imbalance settlement, CfD settlement — Elexon, Xoserve), (5) ESG Reporting Service (TCFD, GRESB, SECR reporting — independently deployable for regulatory submission deadlines), (6) Grid Service (DNO interactions, flexibility services, P272 half-hourly settlement registration).

Ofgem Regulatory API Isolation in Microservices

Ofgem-regulated data submissions: each regulatory submission is mission-critical — REGO under-reporting results in ROC shortfall (financial penalty). Microservices isolation for regulatory submissions: (1) REGO Submission Service (independent service — submits REGO data to Ofgem e-serve, retry logic with dead letter queue on REGO API failure — critical that REGOs are not lost), (2) RO Submission Service (Renewables Obligation Certificate — annual submission, independent from daily operations), (3) FIT Submission Service (Feed-in Tariff — quarterly, independent service). Isolation benefit: regulatory submission services have zero-dependency outages — if the main energy platform has an incident, REGO submission continues independently.

IoT and SCADA Microservices at Scale

CleanTech IoT at scale: 840 wind turbines × 10-second SCADA data = 84,000 data points per minute. Microservices architecture for IoT: (1) SCADA Ingestion Service (AWS IoT Core MQTT → Kinesis Data Streams → S3 raw zone — ingestion only, no processing), (2) Real-Time Analytics Service (Kinesis → Lambda → DynamoDB — current turbine status, alert generation), (3) Historical Analytics Service (S3 → dbt → Redshift — trend analysis, performance benchmarking), (4) Predictive Maintenance Service (Redshift data → SageMaker → maintenance schedule API — isolated from operational services). Service isolation: SCADA ingestion continues even if predictive maintenance service is down — never lose raw SCADA data.

Carbon Market Microservices

UK voluntary carbon market microservices: (1) Credit Registry Service (Verra/Gold Standard API — carbon credit portfolio, purchase, retirement), (2) Credit Pricing Service (BeZero Carbon/Xpansiv market data — real-time carbon price feed, portfolio valuation), (3) Net Zero Trajectory Service (CRREM pathway calculations, scenario modelling — computationally intensive, isolated ECS service with auto-scaling), (4) Offset Recommendation Service (match company emissions profile to high-quality credit portfolio — AI recommendation engine). Service independence: credit registry and pricing services run 24/7 (market hours). Net Zero trajectory and offset recommendation services run on-demand (user-triggered — scale to zero when not in use, saving cost).
