Why PowerShaper is Important

For those who don’t follow energy systems closely I thought it might be useful to demonstrate why developing solutions like PowerShaper is important following yesterday’s loss of interconnector.

Just after 06.08 there was a 100MW loss of connection on the IFA2 interconnector resulting in a drop of the system frequency to 49.65 hertz (normal operating range for the UK supply system is 50 +/- 0.05 hertz) - see image below.

This needs to be recovered urgently to prevent further losses and /or powercuts.

5MW of the loss was may up by aggregated management of in-home batteries.

Exactly the sort of service PowerShaper could deliver if widely deployed.


Thanks for sharing this @ian is it okay if I reference this in this evenings mini-webinar?

Thanks for this Ian. Batteries are great assets for this sort of rapid frequency response service but we probably still cant utilise many that have been installed in homes to date due to woeful lack of interoperability and onerous metering requirements. If someone with a battery signs up to PowerShaper at the moment odds are we wouldnt be able to enrol them as their wont be anyway to talk to them. There is a huge untapped potential resource out there in the wild right now of batteries and other large electrical appliances and the grid of 2050 will seamlessly integrate and utilise millions of such assets in homes and small businesses to provide GWs of flexibility every day but we have a lot of work to do to make this a reality!

Batteries accepted into the Capacity Market
The UK’s latest one-year-ahead capacity auction for 2021/2022 cleared at between GBP45-50/kW/year UK's one-year-ahead capacity market auction clears at record GBP45-50/kW/year | S&P Global Platts.
With modern EV’s having circa 150kW batteries that’s about £6,000 - £7,000 just to have it sat on the drive plugged in if you have a vehicle to grid unit!
