Commercial battery optimisation, paid only on the uplift

Get 7 to 16% more from the batteries you already run

Your battery follows a schedule set at commissioning. Prices move every five minutes and your demand charge is set by a single half hour. Termina runs the battery against the market and against the tariff on each site instead. We measure what it earns on its own first, then we only get paid on the increase.

Why a good battery underperforms

The hardware is fine. The timing is what costs you

Most commercial batteries run a fixed rule: fill from solar, empty in the evening. That rule was set once, at commissioning, and it has never looked at your demand tariff or at what energy is actually worth right now.

It misses the half hour that sets your demand charge

On a demand tariff, one thirty minute peak can set a charge you then pay every month. A battery that empties on a timer is often already flat when that peak arrives.

It ignores your rates, site by site

The same battery behaviour is worth very different money on a flat rate, a time of use tariff, or a demand tariff. Run several sites and they are rarely on the same one. Your battery has never seen any of them.

It leaves the cheap hours unused

There are periods where energy is close to free, or negative. A solar-only charging rule sits those out entirely.

Nobody is watching it drift

Network tariffs are reset each year, seasons move, and trading hours change. Set-and-forget quietly drifts away from optimal and nothing tells you it has.

How it works

We measure first, then we improve on it

You never have to take our word for the uplift, because we establish what your battery does without us, on your site, before we touch anything.

Your installer hands it over

Nothing changes about your system, your warranty, or who installed it. We connect to the battery you already have.

We measure your baseline

We record what the system earns running on its own, including every kilowatt-hour charged from your solar. You see that number, and it is the number we are measured against.

We optimise, and share the increase

We charge and discharge against live market prices, your energy rates and your demand tariff. Our fee is an agreed share of the improvement only, and there is no fee in any period we do not beat the baseline.

Where our fee comes from

You paid for the battery, so you keep what it earns

Everything your system earns by itself stays with you, solar included. We only share in the part that would not exist without us, and the split is agreed in writing before we start.

Illustration only, not to scale. Your share and ours are agreed in writing before we start.

How this compares

What gets compared before we touch your battery

Most of the money in a battery is decided before it ever discharges: which programme it sits in, which pricing model you are on, and what your demand tariff does to the bill. One provider only ever compares their own option. We compare the lot, and tell you if something beats us.

	On your own	A single installer, VPP or retailer	Termina
Deciding when it charges and discharges	A fixed schedule set at commissioning	Their own programme's rules	Live market prices, your rates and your demand tariff, every interval
VPP and aggregator programmes	Not assessed	Only the one they operate	We compare the programmes open to your sites, and say so if one earns you more than we do
Wholesale against traditional retail pricing	Not compared	Usually one model, the one they sell	Both modelled against your actual load before you choose
Your demand tariff	Not considered	Worth asking, it is often out of scope	Checked per site, and part of the baseline we measure
If you are still in contract	Wait for expiry	Usually asked to wait	Battery optimisation can start now, and we model whether breaking or waiting is worth more
Baseline measured before you start	None	Worth asking, it is rarely published	Yes, measured on your own system and shown to you
What you pay, and if it does not improve	Nothing either way	Ask how the fee or credit is calculated, and whether it still applies	$0 to join, an agreed share of the measured improvement, and no fee in a period without one

What's the catch

There isn't one, we are paid on the uplift or not at all

We refuse retailer commissions. There is no subscription and no joining fee, so the only way we earn anything is by making your battery earn more than it did on its own.

Questions, answered

The questions battery owners ask

I'd rather watch it run on its own for a few months first

That is exactly what we do first. From the day your installer hands the system over, we measure how it performs on its own, and that measurement becomes your baseline. There is nothing to lose by starting the measurement now.

I paid for the battery. Why would I share the savings?

You don't. Everything it earns by itself stays yours, including every kilowatt-hour charged from your solar. Our share only comes from the extra we create on top of that.

What if you can't improve on it?

Then you pay us nothing for that period. Our only motivation is to help you make more from your battery, and if we find no better rate in 12 months you get $100 off your next bill.

What does joining cost?

Nothing. There is no joining fee, no subscription, and no commission from a retailer. You only ever pay an agreed share of a measured improvement.

How is this different from a VPP, and do you compare them?

A virtual power plant pays you to make your battery available when the grid needs it, on the aggregator's terms. We run your battery against your own tariff and live market prices to lower your own bill. We also compare the VPP and aggregator programmes open to your sites as part of your baseline work, and if one of them earns you more than we do, we will tell you that. The two questions worth asking any provider are what baseline you are being measured against, and what you pay in a period where nothing improves.

We are locked into a contract until next year

That does not stop the battery work. Optimising what your battery earns does not require a new energy contract, so we can measure your baseline and start on it now. Separately, we will model what leaving early would cost against what a better rate would save, and if waiting is worth more we will say so.

Would wholesale pricing be better for us?

Sometimes, and it depends on the shape of your load rather than on the headline rate. Wholesale exposure rewards sites that can move consumption, which is exactly what a battery lets you do, but it carries volatility a flat rate does not. We model wholesale and traditional retail pricing against your actual usage and show you both before you choose.

Which batteries and inverters do you work with?

Tell us the make and model when you request your baseline and we will confirm compatibility on the spot. We connect to the system you already have, through its own controls.

Does this affect my warranty or my installer?

Your installer stays your installer and nothing about the installation changes. We operate the battery through its own controls, inside the limits the manufacturer sets. If you would like us to confirm this against your specific warranty, send it over and we will read it with you.

Do I have to change retailer?

Not to get your baseline. Once we can see your rates we will tell you whether a better plan is part of the answer, and if it is, we handle the switch. Your battery and your rates work as one system, which is the whole point.

We run several sites. Do they have to be identical?

No. Sites on different tariffs, different networks and different retailers are the normal case, and each one gets its own baseline and its own optimisation. 10,000+ locations are already managed by Termina, so mixed estates are what we are built for.

Can this reduce our demand charges?

That is one of the levers, and on a demand tariff it is often the largest one. A demand charge is set by your highest half hour, so holding charge for that window can be worth more than arbitraging the rest of the day. Whether it applies to you depends on your network tariff, which we check as part of your baseline.
