QA & Testing for UK CleanTech — Ofgem Built In

SCADA and IoT Integration Testing for CleanTech

CleanTech SCADA and IoT testing presents unique challenges not found in standard software testing. SCADA testing: (1) hardware-in-the-loop (HIL) testing — real PLCs (Programmable Logic Controllers) in test environment, (2) OPC-UA protocol testing (verify OPC-UA client correctly reads values from test OPC-UA server), (3) SCADA simulation (GE iFIX or Wonderware simulation mode — test logic without real hardware), (4) edge computing testing (AWS IoT Greengrass local deployment testing — Lambda functions run at edge, unit tested with Greengrass Local Deployment). Key CleanTech test scenarios: sensor failure (NULL or out-of-range reading → graceful degradation), communication loss (edge → cloud disconnect → reconnect data reconciliation).

Ofgem Regulatory Data Quality Testing

CleanTech Ofgem data submissions require high data quality — incorrect REGO submissions or smart meter data lead to regulatory penalties. Ofgem data quality testing: (1) REGO generation volume reconciliation (smart meter MWh total must equal REGO certificate count — test with known test generation data), (2) smart meter half-hourly data completeness (every settlement period 00:00–23:30 must have a reading — test for missing interval detection), (3) Balancing Mechanism notification accuracy (Physical Notifications match SCADA actual generation within tolerance — automated k6 test verifying PN submission within 30 seconds of SCADA reading), (4) EPC data integrity (MHCLG EPC register API response validation — test all rating fields present and valid).

Energy Calculation Accuracy Testing

CleanTech platforms involve complex energy calculations — errors directly cause financial and regulatory impact. Energy calculation testing: (1) unit tests for all calculation functions (kWh conversion, grid emission factors, Scope 2 calculation — parameterised tests with DEFRA known values), (2) SECR calculation cross-check (manual calculation of energy consumption × DEFRA emission factor versus platform output — must match to 4 decimal places), (3) carbon accounting boundary testing (Scope 1 vs Scope 2 vs Scope 3 boundary — test that assets are correctly classified), (4) ISO 50001 energy baseline calculation (3-year average baseline — test with known historical data). Tolerance: SECR carbon calculations must match DEFRA methodology to 0.01 tCO2eq.

Smart Meter and DCC Integration Testing

Ofgem DCC (Data Communications Company) integration testing for UK smart meter platforms. DCC sandbox: DCC provides a developer sandbox with test MPANs (Meter Point Administration Numbers) and test smart meters (simulated). DCC test scenarios: (1) HAN (Home Area Network) join — new smart meter joins the DCC network, (2) half-hourly data retrieval (SMETS2 — retrieve HH data for test MPAN), (3) prepayment top-up (test PAYG credit command), (4) tariff switch (test tariff change command → verify meter reflects new tariff), (5) data quality error handling (partial read — missing intervals, estimated reads). ClickMasters DCC integration: all 5 DCC test scenarios passing in sandbox before production connection.
