Understanding Renewable Energy Guarantees of Origin (REGOs): Benefits, Impact, and Why They Matter
Published: 23/08/202

As the world shifts towards cleaner, more sustainable energy sources, understanding how green energy is certified becomes increasingly important. In the UK, Renewable Energy Guarantees of Origin, or REGOs, play a crucial role in ensuring transparency and credibility in the renewable energy market. But what exactly are REGOs, and why should businesses and consumers care about them? This blog will explore the fundamentals of REGOs, their benefits, and their impact on the renewable energy landscape.
What Are REGOs?
Renewable Energy Guarantees of Origin (REGOs) are certificates issued by the UK government to verify that electricity has been generated from renewable sources. For every megawatt-hour (MWh) of renewable energy produced, one REGO certificate is issued. These certificates are designed to provide transparency, allowing consumers and businesses to know the exact source of their electricity.
How Do REGOs Work
REGOs work as a tracking and certification system for renewable energy. When a renewable energy generator, such as a wind farm or solar plant, generates electricity, a REGO certificate is issued. These certificates can then be traded between generators and suppliers, much like a commodity. Suppliers need to purchase enough REGOs to match the amount of electricity they sell as “green” energy to consumers. This system ensures that any electricity marketed as renewable is genuinely backed by renewable energy production.
The Benefits of REGOs

The Impact of REGOs on Businesses
For businesses, embracing REGOs can be a strategic move. Not only do REGOs allow companies to claim the use of renewable energy, but they also provide tangible proof of their commitment to sustainability. This can be a powerful differentiator in today’s market, where consumers and stakeholders increasingly prioritise environmental responsibility.
Moreover, businesses that generate their own renewable energy can benefit financially by selling REGOs. This creates an additional revenue stream and supports the broader transition to a renewable energy economy.
REGOs: A Key Driver for Clean Energy Development
Beyond the immediate benefits to consumers and businesses, REGOs are a crucial tool in the broader effort to increase the share of renewable energy in the UK’s energy mix. By providing a clear and transparent system for certifying renewable energy, REGOs help build trust and confidence in the renewable energy market. This, in turn, drives investment in new renewable energy projects, contributing to the overall growth and sustainability of the energy sector.
How to Get Started with REGOs
Whether you’re a consumer interested in using green energy or a business looking to enhance your sustainability credentials, understanding and utilising REGOs is a straightforward process. Here’s how you can get started:
- Consumers: When choosing an energy supplier, look for those that offer 100% renewable energy backed by REGOs. This ensures that the electricity you use comes from renewable sources.
- Businesses: Consider switching to a renewable energy supplier that provides REGO-backed electricity. If your business generates its own renewable energy, explore how you can obtain REGOs and potentially sell excess energy back to the grid.
- Renewable Energy Generators: If you generate renewable energy, obtaining REGO certification allows you to sell your energy as certified green energy, potentially increasing your revenue.
In Summary
Renewable Energy Guarantees of Origin (REGOs) are more than just certificates; they are a vital component of the UK’s transition to a sustainable energy future. By providing transparency, credibility, and financial incentives, REGOs empower consumers, businesses, and energy generators to contribute to the growth of renewable energy. Whether you’re looking to reduce your carbon footprint or enhance your business’s sustainability credentials, REGOs offer a clear and effective path forward.
