National Grid, payment not to use electricity and the cost and risk of generation strategy.

In recent days, sunny weather combined with lower demand from the time of year and BH weekend has allowed solar to exceed 9GW at solar noon and be the leading source of power at this time. This has also caused the raw price of electricity to go negative during the day, when normally if it goes negative it's in the middle of a windy night.

I hope EV owners on agile tariffs are charging their cars at these times…

In the south it's been sunny, dry but not as hot as previous Mays. Will there be a temperature point where people start using building air con at significant levels and that adds enough demand to cancel out the negative price?

There will be a point, but it won't be the same temperature across the UK, and humidity and other weather properties will have to be factored in when it comes to how prospective air con users feel.

I recall a story last year where, during the 40C heatwave, the National Grid revealed they paid a record sum for electricity to be imported from Belgium, to prevent London having a blackout.
