Our electricity supply product is zero carbon, 100% renewable, sourced solely from solar, wind and hydro (there’s no coal, gas or nuclear in our fuel mix) and has been audited and verified by an independent third party, EcoAct. They have certified that our supply is matched with guarantee of origin certificates (REGOs and GoOs), which allows our customers to report zero carbon emissions on their scope 2 under the Greenhouse Gas (GHG) protocol market-based method. See our assurance statement here.

Our fuel mix is the ratio of different sources used to generate the electricity supplied to our customers. All UK electricity suppliers must detail their fuel mix on an annual basis to Ofgem and their customers – this is called a ‘Fuel Mix Disclosure’ or FMD. This must also include the associated carbon content so that customers can accurately measure their associated carbon emissions and compare each suppliers’ offered Fuel Mixes. Our current fuel mix can be viewed here.

We purchase all our electricity through our parent company, Statkraft, who procure the electricity volume to match our customers’ contracted amount from the wholesale electricity market.

No. The electricity to your business is supplied via National Grid’s transmission network and local distribution networks (not directly from a renewable generator), so you will be provided with electricity from a mix of sources that the grid is being supplied with at that time from all generators – this may include fossil fuel sources. To ensure your business can show they have procured renewable electricity, we purchase guarantee of origin certificates (REGOs & GoOs) to match the electricity we supply to you. This is currently the only official method for recognising renewable electricity supply in the UK, as mandated and operated by BEIS and Ofgem. The guarantee of origin certificates prove that a quantity of renewable electricity has been generated and purchased by Bryt Energy to match your consumption volumes in a particular year.

REGOs (Renewable Energy Guarantees of Origin) and GoOs (Guarantees of Origin) are certificates issued to renewable generators per megawatt hour of renewable electricity generated. These are purchased by suppliers and demonstrate to the consumer (and Ofgem) that the equivalent of their supplied electricity in a given year came from renewable generation. Without sufficient certificates, suppliers cannot claim to be providing a renewable supply. REGOs are issued within the UK, whilst GoOs are issued to generation within the EU. Both are currently valid within the UK for reporting purposes so we may purchase a mixture of both.

We source the majority of our guarantee of origin certificates through our parent company, Statkraft, but we may also purchase elsewhere to ensure we get the best price for our customers. When we purchase guarantee of origin certificates from Statkraft they can be from Statkraft-owned renewable generation assets, Statkraft-controlled renewable generation assets in their portfolio, or fully independent 3rd party renewable energy generators. However, we always ensure that we only purchase REGOs and GOOs for solar, wind and hydro electricity generation.

These certificates are held by suppliers (Bryt Energy) for fuel mix reporting purposes (rather than the customer) and are submitted to Ofgem.

Currently we cannot provide our customers with the identity of specific renewable generation assets (sites) that we have purchased guarantees of origin certificates for. Therefore, we also cannot issue the specific REGOs or GoOs certificates to our customers to match their supply volume, as these are held by Bryt Energy.

Our supply products are evidenced through our Bryt Energy renewable contract certificates that we can provide to our customers. This certificate confirms that the customer on contract with us is being supplied with electricity that’s been sourced solely from zero carbon, 100% renewable sources, Solar, Wind and Hydro, for that contract period. The customer is therefore able to report zero carbon emissions for electricity consumption in Scope 2 under the Greenhouse Gas (GHG) Protocol market-based method. We also recommend keeping our EcoAct Assurance Statement with your Bryt Energy renewable contract certificate to show your supply has been audited and verified as zero carbon and 100% renewable.

The GHG (Greenhouse Gas) protocol is a set of internationally accepted standards of measuring and reporting emissions. The guidance categorises emissions activities into different scopes for accounting and reporting purposes.

The GHG Protocol have defined three scopes of emissions which are essentially who ‘owns’ those emissions and how much control a company has to change or influence them:

Transmission and distribution (T&D) losses refer to the losses that occur in the transportation of electricity between the sources of generation and the end customer.
T&D losses come under Scope 3 – Category 3: Upstream fuel and energy-related activities. You can report zero carbon emissions for T&D losses for the electricity supplied by Bryt Energy, as we purchase sufficient REGOs and GoOs to cover the electricity lost in the transmission and distribution of your electricity. This is calculated based on the annual loss factor published by BEIS as part of their ‘Fuel Mix Disclosure Data Table’, and is built into our own Fuel Mix Disclosure (FMD).

The GHG protocol Scope 2 market-based method reflects emissions from electricity that companies have purposefully chosen to procure and report on.


This differs from the GHG protocol Scope 2 location-based method, which looks at the average carbon emissions for the country of operation, which is mandatory to include on your GHG reporting. For the UK, you can find the location-based average emission factors from the Government website which are updated annually.
