Where does OVO get its electricity from?

At OVO, we are determined to offer our customers the cleanest energy we can, at the best prices we can manage.

That means saying goodbye to coal and offering you more natural gas and renewables instead.

As an independent energy supplier, our focus has always been on serving our customers rather than generating our own power. So we buy gas and electricity from the energy market and then offer it to our customers at competitive rates.

We also do our best to provide you with the greenest electricity we can, at the best possible prices. We call this balance between clean energy and great value ‘mainstream green’.

The chart above covers April 2015 through to March 2016. It’s based on the figures for our Greener Energy plan, and our standard electricity plans (Simpler Energy and Better Energy). These have been averaged to show our complete fuel mix, alongside the national average. 
 
Overall, we’re doing well – we’ve halved our CO2 emissions over the past three years, and increased the renewables in our energy mix to more than double the national average

We use no fuel generated by burning coal, and over half of the electricity we supply is renewable – a huge 53.1%. We’re really proud of this, as it’s clear proof of our commitment to mainstream green.

Over the past year, our fuel mix included no nuclear power, and no ‘other’ sources – that’s things like dirty diesel generators. Our fuel source besides renewables is natural gas, at 46.9%

This is higher than the national average (at 32.3), but we’re fine with that – there’s no dirty coal in the mix for us any more. 

Our CO2 levels are well below the national average, and we’re responsible for no high level radioactive waste. 

As you might expect, our Greener Energy plan electricity is 100% renewable, with no CO2 emissions (g per kWh).

How has OVO performed over time?

You can see how our fuel mix has improved over the past 3 years in the diagram below.

There are three interesting trends:

  • We have more than doubled the amount of renewables in our mix from 26% in 2013/14 to 53.1% – that’s more than twice the national average.
  • We have reduced our coal reliance from 39% in 2014/15 to 0%.
  • Over three years, we’ve more than halved our carbon emissions – from 486 to 183 grams of carbon dioxide (CO2) per kWh. It’s also 36.9% lower than the national average – more on that in the ‘what about carbon emissions’ section below.

What about carbon emissions?

The chart below shows how the carbon emissions of our mix have been falling over the past 3 years. 

  • Emissions fell 34% from 486 to just 321 grams in 2014/15 – this was achieved largely by eliminating coal. 
  • Over the past year (2015/16) our emissions have reduced again – this time by 43%. 
  • Now, we’re at 183 grams of carbon dioxide (CO2) per kWh – that’s 36.9% lower than the national average, 290 grams of carbon dioxide (CO2) per kWh.

Over three years, we’ve more than halved our emissions from 486 to 183 grams of carbon dioxide (CO2) per kWh – that’s a huge 62.3% decrease overall. 

To put it in real terms, we’ve reduced the carbon emissions of our electricity by over half since 2013/14 – saving 1.20 million tonnes of CO2 over three years

That’s equivalent to 6.1 billion miles* driven by an average new car.

Note - total supply for 15/16 = 2,672,041,000 kWh (488,984 tonnes CO2)
Total supply for 14/15 = 2,001,738,050 kWh

OVO’s renewable electricity

Since April 2015 all new and renewing customers get at least 33% renewable electricity, guaranteed. Where possible we look for opportunities to increase the proportion of renewables in our mix – we certainly achieved this aim in 2015/16.

The fuel mix charts below shows where our renewable energy came from over the past year. It’s mostly hydro power (56.8%), though from a range of renewable energy sources too, including wind (34%), geothermal (3.5%) and biomass (3.3%). We use less solar than you might imagine, at just 1%.

Feel-good energy from OVO

Overall, OVO’s fuel mix picture is a positive one. That means that OVO customers can feel confident that they’ve made a responsible choice when it comes to energy. 

If you’re on our Better or Simpler Energy plan, you get: 

  • At least 33% renewable electricity. 
  • Energy with ⅓ less emissions than the national average.

If you’re on our Greener Energy plan, you get: 

  • 5 trees planted on your behalf through our I Dig Trees programme.
  • 100% renewable electricity.
  • No carbon emissions for your electricity.

 

*Reduction in CO2 rate for 2014/15 from 486 to 290 so reduction of 196g/kWh.  Based on this, total CO2 reduction of 196g/kWh x 2,001,738,050 kWh = 392,341 tonnes of CO2.  Reduction in CO2 rate for 2015/16 rate from 486 to 183 so reduction of 303g/ per kWh.  Based on this, total CO2 reduction of 303g/kWh x 2,672,041,000 kWh = 809,628 tonnes of CO2.

Total reduction in CO2 across the two years of 1,201,969 tonnes of CO2

Average CO2/emissions of cars registered for first time (g CO2/km) in 2015 April to June is 122.1g per km or 196.5g per mile (https://www.gov.uk/government/publications/new-car-carbon-dioxide-emissions).  Total miles saved is 1,201,969 tonnes / 196.5g per mile = 6,148,179,441 miles
