21st April 2017 looks like the first day ever with no coal generation in the UK. Here are some fast facts to explain what is happening:
- This was the first day since the late 19th century that no coal power is being produced in the UK for a 24 hour period.
- Coal went offline at 10pm on 20th April and has yet to come back on.
- Overall in 2016, coal was off for 210 hours. In 2017, it is already been off for over 70 hours.
- Almost exactly a year ago was the first time coal had been offline for 4 hours in the UK and now a year later it’s jumped to an entire day. It’s not even particularly windy!
- On 21st April, the only non-gas burning going on was Drax’s biomass.
- Low carbon renewables (solar, wind and hydro) have generated 10 times more electricity than coal in April 2017. In April, 18% of electricity has come from solar, hydro and wind. L
- Overall, coal use is down 29% in 2017 than the same period in 2016.
- Coal generation is over twice as carbon intensive than gas generation according to the IPCC.
The UK Government hails switching off of coal as part of a carbon reduction plan. However, more needs to be done.
- Today represents the one of the lowest carbon intensities possible for British electricity. Ways to further reduce emissions would be to either: reduce overall electrical demand, invest in more low carbon generation to reduce the supply from gas generation, or to import more more low carbon electricity from abroad.
- Coal may be off the system for extended periods of time over the summer period – but produce for periods in the winter where its capacity has greater value.
