Decarbonising The Energy
Grid With Transparency
RE24 is the technology company bringing transparency to
the business energy market.
Our dedicated 100% green renewable energy marketplace, RE24 Energy Marketplace, connects businesses directly with generators. Delivering traceable, EnergyTag compliant, hourly energy certificates.
Using our business energy platform, RE24 Energy Insights, businesses and generators access their consumption, generation and carbon emission data across multiple sites & countries.
Our Vision
Our vision is to make our electricity affordable and carbon-free at all times.
We believe that complete global decarbonisation of the energy grid will reduce 50% of global emissions.
To achieve net zero by 2050, we believe that renewable energy must be affordable and genuinely green. However, to achieve this, we all need to know exactly what kind of energy we’re buying.
The Problem With Green Energy Tariffs
An estimated third of green energy tariffs in the UK are greenwashed. Conventional energy suppliers sell electricity generated with fossil fuels, offset with the purchase of a renewable energy certificate (REGOs & GoOs).
This practice can reduce investment in renewables and mislead consumers.
At RE24, we’re working to change that. Our energy marketplace connects customers directly with green energy generators, delivering green energy that is completely traceable.
