The Corporate Training Institute (CTI), the training arm of the Transmission Corporation of Telangana (TSTRANSCO), conducted a 14-day online live training programme for 198 members of its O&M staff on the maintenance of substations, lines and safety. Due to the vast expansion of its network and substations in Telangana, there is a shortage of manpower for charging 400 kV, 220 kV and 132 kV substations and EHT lines. To meet this requirement, the management of TSTRANSCO decided to utilise the services of 198 members of Telangana State Power Generation Corporation Limited’s (TSGENCO) O&M staff, on deputation for various substations and EHT line divisions. Owing to the Covid-19 pandemic, it was not possible to organise a classroom training programme for such a large number of employees at the CTI. However, conducting online live training sessions for employees posted across 41 EHT substations located in remote places in Telangana with poor or zero internet connectivity was a major challenge. With the experience gained from conducting the programme, TSTRANSCO is now planning to extend it to all 3,000 members of the maintenance staff in the organisation, in six batches over six months, to upgrade their skills.
