However, as per sample studies carried out by independent agencies including TERI, these losses have been estimated to be as high as 50 percent in some states. In a recent study carried out by SBI Capital Markets for DVB, the TD losses have been estimated as 58%. This is contrary to claims by DVB that their transmis- sion and distribution losses are between 40 and 50 percent. With the setting up of State Regulatory Commissions in the country, accurate estimation of TD Losses has gained importance as the level of losses directly affects the sales and power purchase requirements and hence has a bearing on the determination of electricity tariff of a utility by the commission. Components of TD lossesComponents of TD losses Components of TD losses Components of TD lossesComponents of TD losses Energy losses occur in the process of supplying electricity to consumers due to technical and commercial losses. The technical losses are due to energy dissi- pated in the conductors and equipment used for transmission, transformation, sub- transmission and distribution of power. These technical losses are inher- ent in a system and can be reduced to an optimum level. The losses can be further sub grouped depending upon the stage of power transformati
