The Central Electricity Authority (CEA) has notified guidelines for field efficiency test in hydropower plant (HPP) including pumped storage plants (PSPs).
The objective of the guideline is to guide hydropower generating utilities in the country, to provide a uniform approach for carrying out said tests, its acceptance and to minimise dispute between project authority and the supplier of the units in the project. This guideline mainly focuses on defining the terms and quantities to be used in the process, validity, the period for acceptance of test, agency to perform the test, to specify methods and ways of measuring quantities involved to ascertain the hydraulic/ electrical efficiency of the units and determination of fulfilment of contract guarantees and penalisation in case of failure of its fulfilment. This guideline will be applicable to any size and type of unit comprising generator –motor and impulse/ reaction turbine, and pump-turbine above unit size of 5 MW.
