At V.C. Summer, we issue four plans to our operators every month.  They cover down-powers to 90 ( in 1 hr), 80 (1 hr), 50 (3 hr) and 02 (3 hr) percent.  Those are meant for immediate use by operators at any time during their validity period, and are in the station curve book.  We use BEACON to generate the plans so we don’t track how many load swing calcs we run, but it is generally very few until end of cycle.

Subject: [Pwrrm] Standard Ramp Plans

Two Questions involving standard ramp plans (the plans given to ops for common ramping needs- turbine balance shot, misaligned rod, backing off RTP, securing MFP):

How many cases are run for the standard ramp plans given to ops? (our sites run between six per month per unit to 16 per quarter)

How often are standard ramp plans updated at each site? (we do monthly for two of our sites, quarterly at the other two)
