A school renewal beyond the headline rate
During its December 2025 electricity renewal, an existing school customer in Mackay considered a Zembl proposal. It continued with Bulk, completing a Shell supply agreement and a separate PLUS ES metering agreement.
The review covered more than peak and off-peak rates. Bulk’s analysis included annual spend estimates and invoice comparisons across energy, network, regulated and environmental charges, alongside the contract conditions and metering arrangements.
The remuneration basis was also disclosed. Bulk’s service agreement described supplier-paid commission included in the retailer’s price, capped at $4 per 1,000 kWh. That is the disclosed cap—not the commission actually earned on this renewal.
As the renewal progressed, Bulk updated the pricing, followed up the offer deadlines and lodged the signed supply agreement returned on 11 December. Its 13 December update confirmed that Shell had honoured the most recent offer and provided the countersigned agreement.
The resulting supply term ran from 1 January 2026 to 31 December 2028, with 30-day payment terms. Signed metering paperwork followed on 17 December. The separate PLUS ES order recorded an initial annual meter-service charge of $950 excluding GST, subject to its agreement conditions.
The documented outcome was a retained renewal carried through to completed agreements. It shows the work around the comparison—updating offers, explaining the commitments and following the paperwork through acceptance. It does not establish realised savings or a price advantage over the competing proposal.
Sources and calculation notes
Historical case study. Sources: the renewal analysis and invoice comparisons, Bulk’s service agreement, the signed and countersigned Shell agreement, the 13 December update and the signed PLUS ES order.
The supply term, 30-day payment terms and initial $950 annual metering charge are contracted terms, not realised savings. The initial metering charge excludes GST and remains subject to the agreement conditions.
A direct meter-service charge has a different scope from a bundled metering-and-management fee. The disclosed $4 per 1,000 kWh commission cap is not a statement of actual commission earned. No competitor price advantage is claimed.
