With any hydro scheme, case study solution downstream river environment has an altered hydrograph due to case study solution curbing of major floods and a flow range restricted to case study answer turbine discharge capability. For a peaking station, a common hydrograph shows twice daily fluctuations from off to full capacity discharges often with weekend shutdowns. A peaking station may show constant daily to weekly styles of discharge throughout case study answer year in preference to case study answer strong seasonal sample that may be shown for base load providers, and depending on case study answer scale of case study solution scheme inter annual variability may be low. Downstream results on water pleasant depend on case study solution storage configuration and offtake depth. If case study solution storage is deep and stratifies and case study answer offtake is low, case study solution downstream environment may event frequent temperature and dissolved oxygen fluctuations particularly during case study answer summer period, with case study solution power station injecting cold water from deep in case study answer reservoir into case study solution warmer waters of case study answer receiving environment. In instances where there are downstream pollution resources draining into case study answer river system, peaking power station discharges can cause pulses of polluted water downstream in place of a average dilution effect when working to fulfill baseload demand.
