The month-by-month evolution of what you pay: energy, cost, unit price, demand and power factor, each with its change against the previous period.
The Billing Trends module lines the months up in one table and computes the variation of each item. A high cost says nothing on its own; a cost up 18% while consumption rose 3% does, and points at where to look.
By separating kWh from $/kWh, the table distinguishes two causes the bill blurs together: consuming more, and energy costing more per unit.
The module opens as a dashboard: period indicators with their variation, and six charts covering twelve months against the prior year.
