Harness the power of your homegrown electricity

Max Power is for customers that want to be more sustainable and self-sufficient with their energy.

We know lots of businesses have multiple sites and generate their own electricity.

But, typically, they have to manage each site's power separately.

We created Max Power to change the way these things work - for the better.


Is Max Power right for you?

If you meet these criteria, you could make your energy cheaper and greener with Max Power:

    ✅ Does your business have 2 or more sites?
    ✅ Does your business generate any renewable energy?
    ✅ Do you have a working smart meter or half-hourly meter?
    ✅ Are you happy to export excess energy back to the grid?
    ✅ Can we assess a year of energy data to check you're suitable?

If you don't generate power yourself but want to be involved, check out Max Power: Connect.


How we'll share your electricity between your sites

A site is any property that generates or uses electricity.

We look at each of your sites' usage in every half-hour period. If any of them are generating electricity, we put that energy into a pool. Any of your other sites can then draw from the pool.

You can use this self-generated energy for free.

If there's less energy in the pool than your sites need, you'll import the rest from the grid.

If there's more energy in the pool than your sites need, we'll send the excess to the electricity grid for you.

This process is called time-matching.

Old v New systems Max Power

A new way of managing
multi-site energy

Max Power doesn't just make energy cheaper and greener. It makes it simpler too.

We don't think you should have to treat your different business sites as totally separate entities.

So, when you use the energy you generate yourself, you don't pay anything for it.

For the rest, we give you the same import and export rates across all of your sites.

And have a look at our FAQs:

Do I need to have onsite generation across all of my sites?


No - you only need onsite generation at 1 site as a start.

The more onsite generation you have, the greater the chance of meeting your other sites' demand.

If you're thinking about increasing your onsite generation, we can help with that too.

What type of onsite generation do I need?


We're on board with all technology types that generate energy.

You could have rooftop solar, ground mounted solar, onshore wind or even battery storage.

I'm currently supplied by another energy supplier, what are my choices?


We are currently quoting the import and export tariffs for Max Power up to three months ahead of a start date. Given the current volatility of the energy market we unfortunately cannot quote further out than this just now. If you are within these time frames and interested to know more, please fill in the form above and we'll be in touch!

Do my sites need to be near each other?


No. They can be anywhere across the UK. As long as we can supply your import and purchase your exported energy, we can share energy between the sites.

How much of my time-matched energy will I use?


The sky’s the limit!

We’ve seen customers with high daytime demand use all of the energy they generate. It will vary depending on each business' demands and generation profile.

A more typical example we’ve seen is a customer increasing the amount of their generation they use from 20% to 60% - 3x as much onsite generation than without Max Power.

For my import tariff, can I still have a day/night tariff?


Absolutely! Your import tariff can still be structured how you like - whether that’s a single rate or day/night tariff.

It’s worth noting that energy transported from one site to another will be even cheaper than a night tariff.

Do I have to own the properties to bring them into Max Power?


No. As long as you have the ability to control the energy arrangements you’re good to go.

How long is a Max Power contract?


12 months - but we may extend this in the future.

Do my meters need to be half-hourly or smart?


As long as we can take readings every 30 minutes, your meters will work with Max Power.

How will I know if energy has gone from one site to another?


We'll do all the maths for you and summarise it monthly for each site.

We're currently developing a way for you to see live where your energy is going - more on this soon!
