Curtailed Renewables
Did you know the UK spends billions of pounds each year paying for stranded or curtailed energy.
In the 2024/25 financial year, thermal constraints costs reached a record high of £1.7B* and this is just the start.
These costs are paid by you and me via our electricity bills.

Energy Problems are Everywhere
From micro level to grid scale.
We convert wasted energy into revenue generating flexible compute and heat.
Working with private renewable generators and grid operators, we ensure no Watt is wasted.
Our Solutions
RenewaBlox uses the same technology
to solve energy problems in three different ways
Monetise
Wasted Energy
Grid constraints mean that energy currently being generated is often deliberately wasted by operators. RenewaBlox can monetise this energy.
Electrify
Heat
RBX’s by-product, heat, can be used to solve commercial heating problems, leading to decarbonisation & reduced energy bills for consumers.

Grid Flexibility / Demand Response
RBX can, on demand, absorb excess energy under NESO’s latest flexibility markets - reducing constraints payments for consumers.

Our Mission
We monetise stranded and curtailed energy to help accelerate the energy transition and generate revenues for producers and consumers alike.
Accelerate the Transition to Clean Energy
We are passionate about accelerating the transition to cheap and abundant clean energy. By targeting otherwise ‘lost’ energy from renewable sources, we aim to ensure that no Watt is wasted.
Unlock New Revenue Opportunities
Some energy generators are limited by how much they can export to the grid, often leaving them with excess. We look to co-locate with your power source on a flexible response basis and harness your energy to generate revenues.
Reduce Energy Bills
Instead of the grid paying for electricity it cannot use - a process called ‘curtailment’ - we can monetise that energy at source and reduce overall impact on electricity bills for the end consumer.
True Flexibility
Dynamic Response
Wouldn’t it be great if you could have a flexible dispatchable load co-located with your energy generation to automatically generate real, tangible revenues when you had excess or unused energy?
There has simply never been a way to do this. Until now.
Any Place, any Time, any Size
Our datacentres use a new technology that allows them to be highly flexible, modular and entirely location agnostic.
That means we can deploy anywhere at any scale and run only when you actually need it to - or when it is more profitable to do so.
A UK First
Flexible compute like ours has not yet been deployed in the UK, even though it has already been proven in many other countries across the world.
But now...
Renewablox can bring it to your site.

Who We Work With
We work with anyone who generates energy on a commercial basis, from small operators right up to grid scale producers. Our solution works for all.
Renewable Energy at Supply
Many renewable energy operators are not optimising their assets and leaving potential revenues on the table, such as:
-
Curtailed or wasted energy
-
Unrealised energy from anaerobic digestion
-
Flat & fixed export tariffs
Typically, we work with:
-
Anaerobic Digestors
-
Solar Farms
-
Hydro-Electric Plants
-
Wind Farms
-
Hybrid Sites
Heat as a Service
(HaaS)
UK Businesses face pressure to decarbonise heat immediately, and many cannot easily afford to do so.
Our datacentres can recover wasted heat and re-purpose it for industrial uses:
-
Aquaculture
-
Horticulture
-
Swimming Pools
-
District Heating
-
Distilleries
