A clear, inexperienced future wants power that’s carbon-free. 24 hours a day, 7 days per week.
Meaning matching each unit of electrical energy we use with carbon-free technology.
At Octopus Power for Enterprise, we’ve been serving to companies on their journey in the direction of traceable, matched, carbon-free power for a while with Electrical Match.
Now, we’re working to make 24/7 matching a market-wide actuality, as quickly as attainable.
Let’s dive into what we – and the broader enterprise world – are doing to make this occur.
Why are we speaking about carbon-free electrical energy?
On the UK grid, electrical energy is traded and provide is matched to demand each half-hour. However, present carbon reporting depends on certificates (EACs) which are matched to consumption on an annual foundation.
This strategy doesn’t align with the fact of how the grid works. And it doesn’t present companies all the main points of the place and when the electrical energy that they use was generated.
We’re beginning to see a shift. Local weather Group revealed their 24/7 carbon free coalition framework in June 2025 (which we suggested on). And different voluntary requirements equivalent to SBTi, RE100 and the Greenhouse Fuel Protocol are beneath critiques that are anticipated to maneuver in the direction of a greater reflection of the temporal actuality of electrical energy methods.
Forward of this, we all know that a lot of massive organisations already need provide that’s traceable right down to the half-hour. Companies equivalent to Google, Vodafone and AstraZeneca have publicly pledged their dedication to work in the direction of being powered by 24/7 carbon-free electrical energy.
That is what we’re right here to speak about. Why we predict 24/7 is the way forward for enterprise electrical energy, how we’ll get there, and the way companies can proof their dedication to a greener power system right now by Electrical Match.

Temporal-based scope 2 reporting
An evolution of each of the above carbon reporting strategies, which (a) matches the electrical energy a enterprise makes use of to EACs produced by mills in the identical half-hour, and (b)makes use of the location-based methodology to work out the carbon impression of the remaining unmatched consumption solely
Electrical Match: carbon-free electrical energy for companies
Electrical Match has been supplying companies with carbon-free, matched power since 2023. It powers among the UK’s greatest identified manufacturers:
They get their energy from particular mills that Octopus works with. We allocate sufficient electrical energy to cowl the quantity of power that we count on the shopper to make use of in a 12 months.
We match the technology from these belongings towards the electrical energy that the shopper makes use of in actual time. If the shopper and the generator match precisely, each half-hour of the 12 months, then the shopper will probably be 100% matched.
In the intervening time, our Electrical Match clients are reaching 60% – 80% matching. The precise ranges depend upon climate situations and the way every enterprise makes use of power. Each kilowatt-hour of this matched electrical energy is totally traceable and carbon-free.
Electrical Match clients can confirm that their electrical energy has been matched to renewables, and that this temporal matching has lowered their carbon emissions.
They will proof this by:
- Matching reporting
We run month-to-month and annual matching evaluation utilizing half-hourly buyer and generator information. - Carbon reporting
We present clients their market, location and temporal-based scope 2 reporting, in addition to the carbon profit from being on Electrical Match. - Renewable certificates reporting
We share particulars of the asset-specific EAC certificates that we allocate to clients.
How will we assist clients to extend their matching ranges?
Since launching Electrical Match, we’ve developed a toolkit to assist companies improve their matching rating. It has 4 most important parts.
1. The Electrical Match platform
Every Electrical Match buyer will get entry to a bespoke, all-in platform. Right here they will:
- Hint the place their energy comes from
Prospects can see their consumption websites and linked renewable technology belongings. - Improve their matching
We offer a ahead wanting forecast of technology and consumption, in addition to historic matching evaluation. Prospects can increase long term efficiency by figuring out matching traits. They will enhance day-to-day matching by reacting to climate variations. - Report on their scope 2 emissions
Prospects have entry to view and obtain all the information we’ve talked about above.
All put collectively, it appears like this.

2. Incentivising demand flexibility
Altering enterprise’ consumption patterns could sound difficult. However, we all know that companies can and do flex once they use electrical energy – when given the suitable incentives.
We’ve proven this time and time once more. Since 2023, over 5,000 companies have shifted their option to financial savings of over £34,000 by Saving Periods.
Plus, we’ve the one good product for small companies: Form Shifters. This protects clients cash once they use electrical energy outdoors of 4pm – 7pm. A median Form Shifter strikes 13% of their peak consumption to cheaper, greener durations – and a few clients shifted as much as 95% of their electrical energy utilization out of peak hours!
With clients utilizing power flexibly, we will form demand to higher match renewables once they’re considerable.
3. Entry to a variety of technology varieties
Technology is on the coronary heart of what we do at Octopus. This offers us entry to a variety of renewable belongings.
To extend matching, selection is vital. It’s because renewable applied sciences generate energy at completely different occasions, seasons, or in response to several types of climate. So numerous belongings are usually complementary and assist a extra strong, greater matching proportion.
The chart exhibits how this could look in motion over 48 hours. The sunshine blue line is what the shopper makes use of. Photo voltaic and wind work collectively to satisfy the shopper’s demand for many of this era. On this instance, the solar does the heavy lifting throughout sunlight hours, after which wind plugs the hole in a single day.
4. Profiting from batteries
For Electrical Match clients with batteries, we will use these to extend matching on an intraday foundation.
Take the instance under. This exhibits ranges of carbon-free electrical energy accessible over a couple of summer season weeks versus the power that customers eat. Every day there are durations the place the shopper makes use of extra electrical energy than their matched belongings are producing, and in addition durations the place the alternative is true.
Batteries would take this buyer nearer to 24/7 matching. They will replenish on carbon-free electrical energy when their belongings are producing and use this at occasions the place they want extra inexperienced electrons.
What are the subsequent steps for companies to attain 24/7 carbon-free electrical energy?
We’re excited to push ever nearer to 100% matching and we’re exploring rising applied sciences that may assist us to get there.
Let’s carry this to life with an instance.
The graph under exhibits renewable technology and enterprise consumption over a sequence of days. The beginning of the interval is gusty, which builds up a surplus of fresh energy. However then, the wind subsides and gray stillness takes maintain. There follows a sequence of consecutive days the place the enterprise makes use of extra electrical energy than might be generated by renewables.
That is on the coronary heart of the 24/7 clear power problem that we’re waiting for overcome.
There are two alternatives to develop right here: multi-day storage and constant renewable technology.
Multi-day battery storage
Shorter-duration (intraday) storage has already scaled by lithium-ion batteries. And we’re waiting for see the identical for longer durations. Within the instance above, this might use the excess technology from the beginning of the interval to cowl deficits in a while.
There’s progress with several types of batteries involving metallic air, nickel hydrogen, liquid metallic and sodium sulphur. However none of them has fairly offered the proper resolution simply but.
Constant renewable technology
Photo voltaic and wind power create a powerful basis upon which we will layer different kinds of technology.
Supplementing this with ‘always-on’ types of clear energy would cut back the prospect of constant deficits – and make greater matching attainable. We already use run-of-river hydropower to extend matching. And are wanting in the direction of the scaling of present and new applied sciences on this area too, like geothermal technology.
