UK Renewable energy for businesses

With net zero on the horizon, finding ways to reduce your customers emissions is more important than ever, which is why many UK businesses are opting for carbon-free supply.

At npower Business Solutions (nBS), we offer renewable energy options to suit your customer’s needs, including energy from wind, solar and hydro, as well as fully traceable renewable energy through our UK Corporate Power Purchase Agreement (CPPA). 

Make the smart choice for your customers and join the transition to a net zero future with our UK renewable energy.

UK Business Renewable

Mixture of renewable generation

With our UK Business Renewable, your customers can reduce their carbon footprint, meet their environmental goals, and report zero emissions in their Scope 2 reporting.

UK Renewable Pure

Wind, hydro and solar

If you’re looking for something more, our UK Renewable Pure is generated only from wind, hydro and solar.

UK Renewable Pure Plus

Wind, hydro and solar from a known source

Our UK Renewable Pure Plus provides additional assurance as your REGO certificates are sourced from our generation customers within the United Kingdom.

Our UK Pure Plus Generators

For every MWh of energy you use, we ensure that an equivalent amount of renewable energy is purchased from our customers who generate their own power through wind, solar, or hydro installations across the UK. 

As of August 2023, we have a portfolio of over 60 generation sites, producing circa 500 MW of renewable energy from wind, solar or hydro.


How do REGO certificates work?

Renewable Energy Guarantees of Origin (REGO) certificates provide evidence that a specific amount of electricity has been generated from renewable sources. 

We match the power your customer consumes by securing the corresponding number of REGO certificates, which are usually issued for each megawatt-hour (MWh) of renewable generation fed into the UK electricity system. UK Renewable Pure Plus REGOs are from renewable sources directly contracted with nBS and purchased along with the associated generation.

*UK Renewable Pure Plus and UK CPPA will be reviewed informally by EcoAct in late 2023 as part of our annual accreditation process and will be formally included in the 2024 audit.


EcoAct assurance

The EcoAct assurance stamp gives your customers confidence that their supply is robustly backed by a sufficient amount of REGOs (from UK generation only) and can therefore be reported as zero-carbon emissions power. EcoAct carries out annual audits of our UK renewable products.

Renewable Energy Label

We will provide your customer with a Renewable Energy Label which they can display at their site to demonstrate their commitment to sourcing renewable power.

Corporate Power Purchase Agreements (CPPAs) are becoming an increasingly popular way for large businesses in the UK who don’t have generation assets of their own, to transition to pure renewable energy sources while reducing their carbon footprint. 

CPPAs also provide a stable revenue stream for renewable energy generators, which can help to fund new renewable energy projects and promote the growth of the UK renewable energy industry.

Our UK CPPA offering allows your customers to secure a long-term supply of renewable energy from wind or solar by partnering directly with the UK’s second largest power producer and third largest renewable generator, RWE.
