Avoid generating capacity losses in aging hydropower plants
Turbine generators are essential to hydropower systems, and the loss of a generating unit for an extended period of time could result in costly repair and opportunity costs.
This makes up about 54% of the overall losses. Electricity used internally by the power plant during operations. This makes up about 5% of overall losses. Another 5 to 7% of the original primary energy is lost during the delivery of electricity through the T&D system.
It is primary energy that is converted to heat and then lost as waste heat. Here is where losses occur: It is estimated that of the 66% lost, 59% of it is lost in the generation process. This includes: Waste heat occurring due to inefficiencies in the process of converting primary energy to electricity.
There has not been a single year over the past decade in which power generation operators have not sustained a loss in excess of US$25 million; despite the many millions of dollars invested in risk management and operational safety. To complicate matters, the causes of these losses have become increasingly varied.
There are also losses during electric power transmission. In addition to these losses of energy, there may be non-technical loss of revenue and profit, leading to electrical energy generated not being paid for, primarily due to theft.
