Electricity-cost intelligence for C&I sites

Your electricity bill tells you what you paid.
It doesn't tell you why.

BillinQ reconstructs your bills against interval-meter data to show exactly what's driving demand charges, tariff exposure and avoidable cost — independent of any retailer, broker or equipment vendor.

The problem

Most invoices are difficult to validate, difficult to explain internally, and too late to guide operational decisions.

  • One short peak-demand intervalcan materially increase a month's electricity cost, and it's rarely visible on the bill itself.
  • Tariff structures don't always match how a site actually operates— and misalignment compounds quietly, month after month.
  • Finance and operations teams see the total, not the cause — so decisions about solar, batteries, or tariff-switching get made without knowing what's actually driving cost.

Why now

From 1 July 2026, Victorian network tariffs changed structurally — not just in price.

The new distribution determination (2026–31) changes how large C&I demand charges are calculated, and retailers have little incentive to proactively flag it. The impact varies by distributor, tariff assignment and retail contract.

Demand basis

kW → kVA

Large business demand charges shift to a kVA basis, changing how power factor and reactive load affect cost.

Reassignment

New Medium Business class

Mid-size C&I accounts are being automatically reassigned to a new tariff class — often without site-level review.

Charge floors

Minimum chargeable demand

Stacked incentive demand charges and minimum demand floors mean some sites pay for capacity they don't use.
