The temporal variation of basin yield that naturally occur over a large time series is the most critical parameter for arriving at the power potential of a project. It is obvious that after the projects commenced operation there must be a change in the inflow pattern to the reservoir due to upstream developments, variations in rainfall pattern, inflow calculated using synthetic data at the DPR stage due to lack of observed data. There is variation in the availability of water for the hydro power stations not only due to change in inflow pattern but also due to water allocation to other priority sectors like irrigation, Municipality and industrial usage, loss in the live storage capacity of reservoir due to sedimentation, change in rule curve of the reservoir to moderate flood and ensure irrigation. In this backdrop OHPC decided to the energy delivery capabilities of the existing 5 projects, so that timely action could be taken to rectify any impediment in power generation from these plants as per the guideline prescribed by CEA/CERC in 2001.
System based design energy study of hydro-power stations helped in
- Accurate assessment of the availability water for hydro-power projects and comparative temporal analysis of production capacities
- The GIS database forms a platform for understanding the water requirement Vs power generation capacity of the hydro power plants
