It’s the upgraded version of our Happy Hour plan for solar and battery customers. It pays a bigger feed-in tariff on the energy exported during the evening ‘happy hour’ window, and moves you onto a two-way network tariff where available.

You can join until 31 December 2026.

Yes, where your network offers a two-way tariff. You consent to the switch when you join. We don’t pass the network’s midday charge on, and its evening credit helps fund your Happy Hour Plus rate. If the switch can’t go through, you still get the full Happy Hour Plus rates at no cost to you.

A two-way tariff is how some networks price solar exports. They give a small credit for evening exports, when the grid needs power, and apply a small charge for midday exports above a free daily allowance, when the grid is full of solar. These charges and credits apply to retailers like Flow Power, not to your bill. On Happy Hour Plus we don’t pass the midday charge on, and the evening credit helps fund your higher evening feed-in rate.

Happy Hour Plus is a new product built on a favourable two-way network tariff, and we’re passing that value through as a bigger evening feed-in rate. We’re running it as a trial while we prove the process at scale. It’s available until 31 December 2026, and if you join in that window you keep your rates even if the trial ends, until at least the market price change in July 2027.

No. Some networks charge retailers for midday solar exports above a free allowance (sometimes called a ‘sun tax’). On Happy Hour Plus, Flow Power pays those charges and doesn’t pass them on.

Yes. Queensland customers get the same Happy Hour Plus plan:

• 35c/kWh for the first 15kWh you export between 5:30pm and 9:30pm
• 10c/kWh for any more you export in that window
• 0c/kWh at all other times (no credit, but no charge either)

The only difference is that Queensland customers aren’t moved onto a two-way network tariff. Energex’s trial tariff is currently fully allocated and Ergon (regional Queensland) doesn’t offer a trial. This doesn’t change your Happy Hour Plus rates. If a two-way tariff becomes available, we’ll let you know.

For Victorian and Queensland customers the first 15kWh you export during Happy Hour earns the boosted feed-in tariff of 35c/kWh. Any additional energy exported during the same Happy Hour period is paid at 10c/kWh.

For NSW and SA customers the first 15kWh you export during Happy Hour earns the boosted feed-in tariff of 40c/kWh. Any additional energy exported during the same Happy Hour period is paid at 10c/kWh.

Electricity markets and network conditions differ across Australia, which means export rates can vary depending on your location.

Outside the Happy Hour export window, your feed‑in tariff is 0c/kWh.

That’s because during the middle of the day the grid is often flooded with solar and wholesale electricity prices are lower, so your exports aren’t worth much to the system.

We use data from your smart meter, which records how much electricity you export to the grid in 5‑minute intervals.

Each export interval is tagged with the exact time it occurred, so we can clearly identify exports that happen during Happy Hour from exports that happen at other times of day.

Your bill then applies the Happy Hour export rate to the energy you exported during that window, and the standard export rate (currently 0c/kWh) to exports outside that window.

Happy Hour Plus is not a VPP (Virtual Power Plant), which means that you will be the one calling the shots, and will be in full control of managing your battery settings and exports.

We simply provide the export window; you will need to schedule the exports in your battery app.

Here are some guides on how you can do that.

You can manage your exports using your battery or solar app. At this stage you cannot manage exports directly using the Flow Power app. You can only view your energy usage and export patterns via the Flow Power app.

Eligible feed-in tariff credits are applied to your Flow Power account. If your account has an eligible credit balance, you can request a refund through the Flow Power app in the ‘more’ section.

Any feed-in credit automatically rolls over from month to month and will be applied as a credit to your next monthly bill.

Please note it may take up to 21 days for the credit refund to be processed.

If you cancel your Flow Power contract, any Happy Hour Plus credit will be paid out to you.

You can see all of this in the Flow Power app: 

• A live or near real‑time view of your household usage when live data is available (typically updating every few seconds via smart meter or Flow Hub). 

• A “Today” view showing how your usage and exports have tracked so far. 

• Historical views of your last 30 days (and beyond) in 5‑minute intervals, including how much you exported and when. 

• An energy forecast for the week ahead, highlighting cheaper and more expensive times so you can plan usage and exports. 

• A price efficiency dial that shows whether your current behaviour is likely to improve or worsen your monthly Price Efficiency Adjustment. This makes it easy to see how your habits line up with cheaper and more expensive times, and how much of your solar you’re using or exporting. 

The Price Efficiency Adjustment (PEA) reflects when you use electricity during the billing period.

Using more electricity during lower-price periods may reduce your rate, while using more during higher-price periods may increase it.
