UK Substation batteries upgrade project.

broadgage

I refer here not to utility scale batteries for feeding power into the grid at times of shortage.

Thinking of the batteries installed for switchgear operation (often 110 volt) and for communications or remote control equipment (often 48/50 volt). I recall reading of a plan to upgrade these batteries to ones of much greater capacity in order to ride through much longer outages than were originally foreseen.

IIRC the plan or proposal was that the 50 volt batteries would be increased in capacity so as to give several days autonomy.

The 110 volt switchgear operating batteries were to be duplicated with each set giving 6 hours operation. In the event of any prolonged outage, one battery was to remain in use until automatically disconnected to avoid damage from deep discharge. The second battery was to be disconnected after  a short time and kept in reserve, still almost fully charged. To be put into service under remote manual control when needed.

The purpose was to assist in a black start after a multi day shutdown.

Does anyone have more details, links etc ?  Not certain why I have thinking about multi day shutdowns

  • I hope that all this is just speculation Harry. Even the suggestion that the UK electricity Grid fails in any way is so far off expectation that it is completely unacceptable. Those who are responsible for this ridiculous state of affairs need to be locked up for a very long time, probably in a mental institution. I note that my warnings here for a number of years were treated with derision and poo-pooed as being nonsense.  IF the Grid were to fail in any way including load shedding, the economy and the country would be completely wrecked, if it has not been already. I note from the news this morning that the Government (NAO) cannot account for £16 Billion of OUR money during Covid, a fully artificial crisis. The serious fraud office must be very busy at the moment, or more likely they are lounging at home!

    The IET is still unaware that "Green" policies by stupid politicians and the Editor of E&T magazine have completely failed, and have been a hugely expensive "virtue signalling" exercise with a terrible outcome, which can only get worse as the weather gets colder.
