What do we mean by 100% renewable electricity?

All our customers' homes and businesses get 100% renewable electricity, at no extra cost. Eligible businesses are SME customers that sign a contract directly with E.ON. Electricity sourced from E.ON’s renewable generation assets, supply agreements with independent UK wind generators and the purchase of renewable electricity certificates. The electricity supplied to homes and businesses comes from the National Grid and DNOs.

How do I get involved?

If you're a customer, you already are. Cleaner electricity should be the norm, not the exception. So we’ve made it standard1 for all our customers, without making you pay a penny more – you don’t need to do anything.

What about small businesses?

If you’re a small business, we’ll switch you to renewable electricity for free the next time you renew your contract or sign a new one. (Unless your smart meters take readings every half hour, in which case you might not be eligible.) 

Do your bit for the planet

Using 100% renewable electricity is an easy way to bring your carbon footprint down without disrupting your day-to-day. And if you're not already with us, it's free to switch.

Our energy mix

Think of the National Grid like a bucket. All the electricity that’s produced in the UK goes in there, and customers like you take it out. We can’t guarantee all the electricity in the bucket is renewable, but we can make sure our portion is. We have a long history in renewable energy, going back to the development of our first onshore windfarm in 1991.

We generate our own electricity

We've been pioneering the UK's renewable energy future for the past three decades, investing more than £3.3bn in UK renewables in the last ten years alone. 

How do we generate our own renewable electricity?

We’re proud to be one of the only energy companies who actually produce our own electricity, instead of just buying it. In fact, our biomass power plants in Lockerbie and Sheffield create enough to power 100,000 homes up and down the UK. We start with natural material (normally waste wood), burning it to heat water: water turns to steam, steam powers the generator, and we make electricity. We don’t import our biomass from overseas, and we tend to use material that would otherwise go to waste – like offcut wood from sawmills.

How do we work with other renewable generators?

We work with UK-based generators who create Ofgem-certified renewable electricity. Right now, we’re working with wind farms up and down the country: the Scottish Highlands, the Yorkshire Moors, the Sussex coast. Don’t underestimate the power of the wind - our partners’ sites can power up to 170,000 homes and offices. And in fact, we helped to build a few of them ourselves.

How do REGO certificates work?

It might sound complicated, but the certificates actually make everything more transparent. The industry regulator, Ofgem, introduced the Renewable Energy Guarantee of Origin (REGO) certificates to help you track your energy back to a renewable source. Firstly, a renewable generator gets REGO certificates. 1,000 units (which is one megawatt hour) of electricity equals one REGO certificate. Then, we buy those certificates to make sure we match what you’re using. 

Other ways to be more sustainable

100% renewable electricity is just one step towards running a more sustainable home or business. We have other solutions that can help you improve your low carbon credentials.
