Momentum Energy: ownership, plans and where it sells

Momentum at a glance

From Momentum Energy's own website and the Essential Services Commission.

Why the ownership matters to some customers

Buying from Momentum does not mean your electricity comes from Tasmanian hydro; power from all generators is mixed in the grid. What it does mean is that your retailer's profits flow to a government-owned renewable generator, which is why Momentum features in searches for Australian-owned and government-owned retailers.

Comparing Momentum in Victoria

Because most of Momentum's customers are Victorian, the yardstick for its plans is the Victorian Default Offer for your distribution zone. For 2026–27 the residential flat-tariff VDO ranges from $1,481 a year in the CitiPower zone to $1,748 in AusNet Services, for 4,000 kWh. Every Victorian plan must say how it compares with the VDO, so start with that percentage.

Victoria's own rules also help Momentum customers who have not compared for a while. Your bill must say whether you are on Momentum's best offer, and from 1 July 2026 any retailer must check at least once a year that customers on plans more than four years old are paying a reasonable price. Victorian Energy Compare lists every Momentum plan next to every competitor's.

Regulator actions

In 2025 Momentum paid 20 Essential Services Commission penalty notices totalling $764,380 for alleged breaches of Victoria's family violence protections, including disclosing the confidential information of family violence affected customers without their consent.

How to check Momentum's plans against the market

Retailers must publish their generally available plans to the government comparators: Energy Made Easy in NSW, Queensland, SA, Tasmania and the ACT, and Victorian Energy Compare in Victoria. Each plan there has a standard fact sheet listing every rate, fee and discount condition, which is the fairest way to line Momentum's plans up against everyone else's.

Start with how far below the reference price each plan is (the Default Market Offer in NSW, south-east Queensland and SA, or the Victorian Default Offer), then run your own annual usage from a recent bill through the shortlist. The same retailer can be among the cheapest in one network zone and not in another.
