Electricity tariffs

Dynamic electricity pricing and home batteries

Dynamic electricity prices change by time period. A battery can move part of household electricity use between those periods, but the result depends on price spreads, losses, capacity and the contract available in your country.

How can a battery use dynamic electricity prices?

It can charge during selected lower-price periods and discharge during selected higher-price periods. A useful strategy also keeps enough capacity for expected household demand.

Look at the spread

The difference between charging and avoided purchase prices matters more than either price in isolation.

Include efficiency

The sell or avoided-purchase value must be compared with the energy and cost required to charge the battery.

Prices are not forecasts

Past volatility does not guarantee future spreads. Test conservative and less favourable scenarios.

Contracts differ by country

Supplier terms, settlement and taxes are local. Confirm them before relying on a strategy.

In depth

What to know before you decide

Dynamic electricity tariff, agile tariff and time of use tariff

These terms all describe the same underlying idea: the price you pay changes by hour or by period instead of staying flat. A dynamic electricity tariff typically follows the wholesale market hour by hour, while a time of use tariff uses fixed bands. Both can create the price gap a battery needs.

The gap, not the label, decides whether shifting energy is worthwhile. If the difference between cheap and expensive hours is small, no battery can turn it into a meaningful result.

What a battery can and cannot do with hourly prices

A battery can charge in selected hours and release that energy later, which moves cost rather than reducing consumption. Round-trip losses mean you recover less energy than you store, so any calculation must include them.

PowerHub ONE charges at up to 800 W on a suitable 230 V outlet, or up to 2.4 kW peak on a dedicated circuit. That limit determines how much energy you can actually move inside a cheap window, which is often the real constraint rather than capacity.

Frequently asked questions

Answers for an evidence-based decision

Only when the selected settings, price data, available capacity and expected demand support that decision.

The battery still stores energy, but a fixed tariff may offer little or no price-shifting opportunity without solar surplus.

No. PowerHub is not an electricity trader; third-party services and local availability determine any market participation.
