Sell your power to businesses, not just the grid.
The Smart Energy Markets private energy market matches your output to business buyers every half hour, so you can sell on longer, fairer terms than a standard export tariff.
Who it’s for
Owners of operating or planned renewable generators.
- Technology
- Solar, onshore wind, run-of-river hydro and anaerobic digestion. Battery storage is assessed separately.
- Size
- From small rooftop arrays to multi-megawatt sites.
- Stage
- Operating, under construction or consented.
- Metering
- A half-hourly export meter, or one that can be fitted.

How the market works
Generators on one side, business buyers on the other.
Our licensed supplier partner sits in the middle. Every half hour it matches generators’ output to buyers’ demand and settles it. The electricity travels over the public grid.
A day’s 48 half hours
Matched and settled every half hour. The electricity itself travels over the public grid.

Step 4 of 4: Unmatched output is still sold
Output that isn’t matched to a buyer in a half hour is sold through our licensed supplier partner. Your generator contract sets out the price for it.
Routes to market
Why sell through a private market?
How the private energy market compares with the two usual routes for a generator’s output.
| Smart Export Guarantee | Utility PPA | Private Energy Market | |
|---|---|---|---|
| Price basis | The supplier’s export tariff, often variable | Negotiated, usually for large sites only | Matched to business demand, on the basis set out in your written offer |
| Contract length | Often 12 months, or variable | Typically 3–15 years | Agreed for your generator and set out in your offer |
| Size | Up to 5 MW | Usually several MW | From small rooftop arrays to multi-megawatt sites |
| REGO value | Often kept by the supplier | Negotiated | Set out in your generator contract |
| Know who uses your power | No | No | Yes, where buyers agree to be named |
REGOs are Renewable Energy Guarantees of Origin, the certificates that show electricity came from a renewable source.
