Regulation with the LMS100Primary Frequency Regulation• 30-second response capability is in excess of 25 MW• 50% contribution within 15-seconds, 100% contribution

within 30-seconds (field data 20 to 25 seconds)• Available with Reserve Margin Control, adjustable

deadbands, adjustable limits and adjustable MW floor.

Automatic Generation Control• Highly suited to the LMS100, offering ramp rates up to 53

MW/min across the power range• Minimum Stable Generation set as low as 20 MW by some

sites (emissions considerations influence level)

Tertiary Control• The LMS100 offers reliable 10-minute starts to full load from

a non-spinning reserve status
