Reducing incidents, improving power supply reliability

Ho Chi Minh City (HCMC) has been actively implementing the project proposal of developing a smart city in the period 2017-2020. Supporting the breakthrough decision of HCMC's leaders in improving urban management capacity and life quality of the city's residents, on behalf of the electricity sector, Mr. Pham Quoc Bao, Deputy General Director of EVNHCMC said: "The sector is gaining a lot of advantages because it has actively implemented smart power grid development programs under the Prime Minister's instructions in approval of the Smart Power Grid Development Project in Vietnam.

Basically, the EVNHCMC’s roadmap being implemented is fully appropriate and ready to be integrated with basic configurations of the smart urban project proposal of the city. Therefore, the project after being announced is a great motivation for EVNHCMC to promote the implementation of the project proposal and is expected to contribute to the overall success of the Smart Urban project of HCMC.

As per specific analysis, from 2016, EVNHCM has completed developing a Modern power grid management system (SCADA/DMS) and in 2017, set up the Remote control center of power grid with the tasks of monitoring, supervising the power supply, automatic control throughout the grid of the city. EVNHCMC has completed the transfer to the remote, unmanned operation at 42/50 110kV intermediary station of the city. The remainder shall be completed in 2018, to ensure that all the 110kV substations throughout the city are remotely operated via the operating center.

EVNHCMC is also implementing the automation plan for 220kV distribution power grids; promoting the application of live-line working in order to mitigate the disruption time of power supply. The unit also successfully studied, manufactured and put into operation 21 insulated cleaning sets for 110kV and 220kV power grids with high pressure water taps (online porcelain cleaning) to maintain the grids without outage, contributing to reducing incidents and improve the reliability of power supply to customers.

Especially, EVNHCMC bravely piloted the Micro Grid model (regional smart power grid) in 4 areas: Hi-tech Park in district 9, commercial offices along main roads in District 1, Mieu Noi residential area in Phu Nhuan district and residential area in District 7 as the basis for the replication of this model in 2018 and the coming years.

Diversifying forms of electricity payment

Remarkably, currently, the Electricity sector of the city has implemented 19 transaction methods with customers through 4 forms of online transactions of Customer Service Center 1900545454, Email: cskh@hcmpc.com.vn, Website: http://cskh.hcmpc.vn/ and the customer care application of EVNHCMC, Zalo on mobile devices.

The corporation’s Customer Care Center also was put into operation since 2014 and deployed value added services such as 8055, 8655 mailboxes to support customers in searching information of electricity bills and, bill debts, cause of cut-off power and power consumption recording schedule. Application for tracking power load chart was provided; customers installing remote data collection system can directly monitor the load and the power using situation on the website: cskh.hcmpc.vn.
