Tab 1: Engineering Telemetry Summary
During Quarter 3, the facility's grid-scale battery energy storage system logged a roundtrip charge-discharge efficiency of $94\%$. Telemetry sensors recorded energy input and output strictly across the battery cell terminals during active storage cycles.

Tab 2: Financial Utility Billing Report
Energy billing records for Quarter 3 indicate that total kilowatt-hours ($\text{kWh}$) purchased from the regional utility grid exceeded baseline operating projections by $25\%$. Financial auditors concluded that net facility energy losses were far higher than the $6\%$ loss implied by battery telemetry.

Tab 3: Operations Maintenance Log
All auxiliary HVAC cooling units and thermal control systems operate on dedicated grid sub-circuits that bypass battery cell meters. Operational policy mandates continuous thermal conditioning whenever ambient site temperatures exceed $30^\circ\text{C}$. During Quarter 3, site temperatures exceeded $30^\circ\text{C}$ for $65\%$ of operational hours.

Based on the information provided across the three tabs, which of the following statements, if true, help resolve the apparent discrepancy between the $94\%$ battery efficiency reported in Tab 1 and the $25\%$ excess energy consumption reported in Tab 2? Select all that apply.
