Description:1. CFS values throughout the hour are averaged into an hourly flow value. 2. That value is rounded up to the nearest 50 cfs. 3. Values are sent delayed by four hours. The calculated flow is the difference between the metered flow downstream of Pit 1 PH at PH71, and the Pit 1 powerhouse flow (itself a calculated point based on generation and performance curves) . Since it takes between 15 and 30 minutes, depending on flow volumes, for water to travel from the powerhouse to PH71, metered flow from 22 minutes ago at PH71 is used in the calculation. PG&E testing determined that 22 minutes is a good average time delay that minimizes spikes on the leading and trailing edges of load shifts at the powerhouse.
