Start from Standstill Condition

Hi all, My unit is six Gas Turbines SIEMENS SGT5-2000E with power output 186 MVA, 16 stages compressor and 4 stages turbine. Because of this pandemic, our gas turbine is no longer in operation, but currently, our GT is stay at turning gear speed so that the GT is always ready for start. That is based on our SOP, but after 3 months, and the network demand is still low, we'd like to reserve all the GT in standstill condition

Do anyone have experience in starting this kind of GT from standstill condition?

What does the manufacturer's operating manual and or the company rep say? Typically a minimum time on turning gear is stipulated prior to run-up to eliminate any developed sag...

Has the option of sharing the time on turning gear between units been considered? This could maximize power savings while still satisfying maximum permissible at-rest shaft times.
