Solar net-metering customer Bernard Wentzell files response in DRO appeal citing three-way discrepancy between NSPI meter records, AMI data, and SolarEdge inverter generation totals for January–March 2026 billing period

M12947 · NSPI DRO Appeal - Meter and Power Consumption - Bernard Wentzell

AI summary

Appellant Bernard Wentzell filed exhibit W-8 on August 4, 2026, disputing a $738.61 bill covering 59 days (Jan 24–Mar 24, 2026) under Billing Procedures for domestic service at rate code 03BC2/03BG2.
Wentzell identifies three conflicting generation figures from Nova Scotia Power's own records: 752.68 kWh (meter usage column sum), 797.44 kWh (meter read difference × 40 multiplier = 795.64 kWh), and 817 kWh as credited on the bill — none of which align with each other.
SolarEdge inverter software reports total generation of 2,573.2 kWh for the billing period, producing a discrepancy of approximately 1,777.56 kWh versus the NSPI meter-indicated generation figure, raising serious questions about Advanced Metering Infrastructure accuracy.
Day-level comparisons submitted by Wentzell show consistent gaps between SolarEdge generation and NSPI-credited above-consumption amounts (e.g., Jan 24: SolarEdge 70.5 kWh vs. NSPI credit 36.92 kWh; Feb 22: SolarEdge 94.9 kWh vs. NSPI credit 63.12 kWh), supporting the appellant's contention that net generation is being systematically under-credited.
Multiple 'No AMI Read Available' gaps appear throughout the billing period data tables, suggesting Advanced Metering Infrastructure communication failures that may be contributing to inaccurate consumption and generation accounting under the Residential Solar Pv Program.
