Every business leader knows the end of the year is chaos. Deadlines pile up, priorities compete, and energy contracts slip down the list. Here’s the reality: leaving your renewal to the last minute can cost your business.
The year-end crunch
November and December are peak months for expiring commercial energy contracts. These contracts are for large businesses, typically those using more than 100,000 kWh of electricity each year (the threshold varies by state) or spending over $3,000 a month.
Approximately 60%* of large business customers have contracts expiring in this window, which creates a surge in demand. Wait too long and you risk missing competitive offers or being rolled onto expensive default rates.
Luke Pearce, Zembl Commercial Energy Manager, says: “At the end of every calendar year the market sees a surge in large business contract renewals, which puts pressure on retailers’ capacity and reduces the flexibility of offers available. Securing your next agreement early helps you avoid default rates and gives you greater choice and negotiating power for your next contract.”

What happens if you don’t act
Do nothing and you could find yourself stuck on default market rates, often well above your previous contract. That is money straight off your bottom line. In December, retailers can also afford to be choosy. Expect fewer favourable terms and slower turnarounds.
Default rates also come with no leverage. You pay more without the benefits that a negotiated plan can include, such as fixed rates, tailored contract lengths, or greener energy options. For businesses already managing inflation and higher operating costs, that extra spend hurts.

How to prepare
Get ahead by gathering usage data, past rates, and any changes in your energy needs. Walking into renewal discussions with the right information helps retailers tailor offers that actually fit your business.
Think beyond price. Decide what matters most to you: cost certainty, sustainability commitments, or flexibility in contract length. Clear priorities keep negotiations on track.
