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 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.
How Our Solution Works
RenewaBlox uses the same technology
to solve energy problems in three different ways
Grid
Flexibilty
RBX can, on demand, absorb excess energy under NESO’s latest flexibility markets - reducing constraints payments for consumers.
Offtake for stranded / wasted energy
Grid constraints mean that energy currently being generated is often deliberately wasted by operators. RenewaBlox can monetise this energy.
Heat-as-a-Service (HaaS)
RBX’s by-product, heat, can be used to solve commercial heating problems, leading to decarbonisation & reduced energy bills for consumers.

Anywhere, Anytime
Most data centres require close to 100% up time, proximity to end consumer, and specialist internet connections to operate profitably.
This is where ours differ.
We can operate anywhere, anytime and at any scale - even in the most remote locations. This allows us to provide a totally unique solution that ensures that no amount of energy, no matter how large or small, goes to waste.
Heat on Demand
There are other benefits too.
95% of electrical energy is converted into usable heat as a natural part of the operating process. That heat can be put to work on your site, saving you money on additional energy costs, or freeing up power for profitable export.
Our advanced monitoring systems allow us to remotely manage our Data centres
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
