A while back I stumbled across the spec for an equivalent system in England, where the generator has dedicated fibre to the local substation, where the data passes through a Modbus/TCP -> 4-20mA -> Modbus/TCP "firewall" before being allowed anywhere near the network's SCADA system.
The spec noted that this did seem a bit convoluted and they would hopefully find a better way of achieving comparable security soon...
