When to export

  • Best-paid 3-hour run starts 16:00, averaging 16.00p per kWh.
  • Best-paid half hour today is 16:00 at 16.00p.
  • Worst-paid is 00:00 at 9.00p, so it is worth holding generation back if you can.

Use your own figures

What could Prime Outgoing Octopus pay you?

South East England

Use your own export and rate assumptions. Variable payments depend on when electricity reaches the grid.

Estimate annual export earnings

Enter your annual export and the rate you expect to apply. The best currently displayed payment is 16.00p per kWh (16:00–19:00), but it is deliberately not assumed for your whole year.

Enter all of the figures above to see the calculation.

This values only the annual kWh and rate entered. It does not forecast solar generation, household use or future export prices.

Test a battery export spread

Enter the actual import cost, intended export payment and your battery efficiency. The displayed export rate is not assumed to be the cost of charging the battery.

Enter all of the figures above to see the calculation.

Gross energy spread only, not profit: excludes standing charges, battery degradation, inverter losses beyond the stated round-trip efficiency and any change in household consumption.

The short answer

Who Prime Outgoing Octopus is most likely to work for

Prime Outgoing is most compelling for a battery home that can deliberately place meaningful export into the 4pm to 7pm peak.

In its favour

  • Higher 4pm to 7pm export rate
  • Predictable repeating schedule
  • No exit fee in the current product data

Against it

  • Lower payment for the other twenty-one hours
  • Best results generally need storage
  • Battery spread is not the same as profit
Read the fuller verdict and trade-offs

For solar without storage, much of the export may receive the lower rate. Compare actual export timing with a flat export tariff rather than choosing on the peak figure alone.

  • The headline peak rate applies for only three hours; most unshifted solar export may earn the lower rate.
  • A gross difference between cheap and peak prices is not battery profit because losses, degradation and import costs are excluded.
  • Using solar electricity in the home can be worth more than exporting it and buying electricity back later.

Household fit

Who Prime Outgoing Octopus might be good for

The right answer depends on your equipment, routine and tolerance for changing prices—not just how much electricity you use.

Likely to suit

  • Solar-and-battery homes able to export between 4pm and 7pm
  • Households wanting a fixed export schedule rather than day-ahead prices
  • People prepared to compare self-consumption with peak export value

Less likely to suit

  • Solar homes without enough late-afternoon generation or storage
  • Households that export almost everything around midday
  • Anyone without a smart export meter and export MPAN

Before switching

Check the requirements and what will affect the result

What you need

  • Eligible small-scale generation and an export MPAN
  • A smart meter capable of recording half-hourly export
  • An Octopus Energy account and an import tariff currently compatible with Outgoing
  • Acceptance of the current Prime Outgoing product terms

What drives what you earn

  • How many exported kWh land between 4pm and 7pm
  • How much surplus generation remains after the household uses its own electricity
  • Battery capacity, round-trip losses and the import cost of any electricity used to charge it
  • The selected region's export rates

How it works

How Prime Outgoing Octopus sets its prices

There are two repeating export bands every day: a three-hour peak from 4pm to 7pm and an off-peak rate for the other twenty-one hours.

Read the full pricing explanation

A smart meter records export by time, so electricity sent to the grid in the peak band earns the peak rate.

Solar generation often falls by the evening. A battery can move surplus daytime generation into the more valuable period, but charging losses and the value of using that electricity at home still need to be considered.

Practical advice

Getting the most out of Prime Outgoing Octopus

1

Measure when you export

Use half-hourly export data to see how many units already land between 4pm and 7pm before assuming the peak rate will dominate earnings.

2

Keep the battery calculation honest

Include round-trip losses and compare the import cost or forgone self-consumption with the extra export payment.

Match the tariff to your home

Solar, a battery and your import tariff change the answer

Export income is only one side of the decision. Electricity used at home avoids an import purchase, while storing and exporting later loses some energy in the battery.

Solar without a battery

Compare the rate paid when your panels naturally export, usually through the middle of the day. A high evening rate is less useful if you cannot move generation into it.

Solar with a battery

A battery can move export into a valuable band, but the headline spread is not profit. Allow for round-trip losses, degradation and the import cost or self-consumption value of the electricity stored.

Choose import and export together

Check whether the export tariff restricts the import tariff you can hold. Even where it does not, the best export rate can be outweighed by a poor import fit for the same home.

Alternatives

These are other smart-tariff comparisons from the two suppliers, not a claim that every option suits the same household.

Outgoing Octopus

Outgoing pays one flat variable rate at every time.

More detail

Prime Outgoing may pay more when export can be moved into 4pm to 7pm, while the flat tariff is simpler for unshifted daytime solar.

How to switch

Moving to Prime Outgoing Octopus

  1. 1

    Confirm the generator, smart meter and export MPAN are ready before applying.

  2. 2

    Confirm you are an Octopus customer and that your import tariff is on the supplier's current compatibility list.

  3. 3

    Compare the selected region's peak and off-peak rates with the times your home actually exports.

  4. 4

    If using a battery, model charging losses and the value of self-consumption rather than treating the peak-rate spread as profit.

Frequently asked questions

Are Prime Outgoing rates payments or charges?

Payments. It is an export tariff, so the rates show what Octopus pays for each kWh sent to the grid.

When is the Prime Outgoing peak rate?

The peak export band runs from 4pm to 7pm local time each day. The other twenty-one hours use the lower export rate.

Do I need a battery?

Not as a general export requirement, but a battery is usually needed to move substantial midday solar generation into the 4pm to 7pm peak. Without one, compare your natural export timing with a flat export tariff.

Is the difference between the two rates battery profit?

No. It is a gross price spread. Battery losses, degradation, the source and cost of charging electricity, and the value of using the electricity at home are separate.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
