Electricity supply to Jersey under threat.

broadgage
TPTB in France have threatened to cut of the power to the island of Jersey as part of an ongoing dispute.


Jersey is very reliant on power from France via several submarine cables.

What I can not find is any up to date information on 

Maximum demand on Jersey

Average demand.

On island generating capacity.

Contingency plans for extra generation.

Contingency plans for load shedding.


I would urge that we confine ourselves to the strictly ELECTRICAL aspects and refrain from political or brexit related arguments.

    Normandie 3 is a High Voltage Alternate Current (HVAC) 90 kV link.  Prysmian Group did the cable for it in 2013


    Normandie 1 is another  90 kV 3 core cable    (prysmian did that one as well.)



    In French HV distribution,  a voltage of 90kV phase to phase AC without neutral  is a standard level used as an intermediate level of distribution / transmission , much as 132/ 33kV is used in the UK

    French voltages of 'transport electrique' are 400kV, 225KV then 63 or 90kV for regional, and 20kV and then local distribution at 400/230 with neutral as we would recognise.

    Like us they have preferred levels at which generation of different sizes may be added - so 10- 40MW stations might feed in at 90kV, and smaller sites in the 0.25-10MW range at 20kV, and less than that,  down to the odd roof top solar feed in at 400/230.
