Shunt Capacitance VARs

Hi,
I am trying to figure out how to calculate the shunt capacitance VAR for a project I am looking over.
The data I have is:
Voltage45kV Conductor Size=2-795kcmil Length miles Resistance=0.71428 ohms (total) Reactance=7.11065 ohms (total) Susceptance†.187 micro-siemen Current39.167 amps Power Factor=0.967 VARsQ.429 MVAR Power6.038 MW
The shunt capacitance vars they are showing are 10,258.41 KVARs.
Thanks for your hep.

That is correct. The total 3 phase shunt vars is given by 3(Vlg^2)*Ylg Voltage l-g45/root(3)9.2 KV Ylg†.2 micro-seimens Shunt vars (3 phase) =3*(199200^2)*86.2*10^-6 .26*10^6 VAR .26 MVAR ,260 KVAR or reduce it to (345^2)*86.187 *10^-6 .26 MVAR
Numbers rounded to reasonable (but still overly optimistic) precision. No-one knows the resistance, inductance and capacitance to 5 sig figs-too many Bougerre Factors exist .
