Automating a gas storage field

McDonald Island Gas Storage Field has expanded from average deliverability of 200 MMcfd to 1.2 Bcfd. It represents near thirty percent of P. G. and E.'s total abnormal peak day firm load demand. The storage field is capable of fast response to large scale load fluctuation due to either abnormal peak day firm load demand or unscheduled outage of any of P. G. and E.'s major transmission lines. It has both a large deliverability and fast response capabilities. This storage field is in the true sense a system inventory control type storage facility, as opposed to the base load type of storage facility.
