Currently, HEPCO is performing the main street lighting task for 336km, with a lighting rate of 98%. Lighting the street, alley 142km, lighting rate 65%. Total installed capacity is 1.830KW, with 15.372 lamps of all kinds. In which, 5.671 led bulbs, accounting for 37%.
According to a representative of HEPCO's leadership, because most of the public lighting system of the city. Hue still uses more than 60% of old and degraded reflectors, and energy-saving LED bulbs account for less than 40%, so they consume a lot of electricity.
In addition, the multi-route lighting system controls the power-saving mode at late night by reducing the number of lights by half (phase-cutting), which still has many shortcomings, such as uneven lighting, causing problems. The "light potholes", which do not ensure traffic safety and reduce the aesthetics of the route, do not meet the standards but have not been invested or replaced, are also the reasons for not reducing the electricity as desired. .
However, in order to meet the needs of public lighting, traffic safety, and save electricity in the dry season, HEPCO annually deploys effective energy-saving solutions. This year, the weather forecast is complicated, with intense heat, so the demand for electricity of the people will increase. In order to contribute to the electricity industry to reduce capacity, starting from May 20, HEPCO has cut down the hours of off-peak lighting.
Specifically, in the downtown area. In Hue, the current evening power-on time is implemented starting at 18:20 and cutting off the power at 4:50 am the next morning. Previously, the central areas were 100% energized from the beginning of the night to the morning. Areas 1 and 2, similar lighting power on and off hours. Only difference is that before, these two areas from 23:30 to cut 1/2 of the lights alternately along the route, now cut off at 4:50 am every day. The area of wards and communes is expanded, the evening power-on time begins at 18:30 and the electricity is cut off at 4:30.
Particularly in priority areas such as Le Duan and Hung Vuong streets (depending on each section) and the western quarter, the time for alternating lights is cut off at 22:30 and the power is cut off at 4:30. Previously, these areas were prioritized to turn on electricity from the beginning of the night to the morning.
Compared with the winter lighting, HEPCO now adjusts to reduce about 1 hour of power on/off, that is, the winter power-on time frame is performed at about 17 pm daily and the power is cut off at 6 am. In the summer, the electricity is turned on at 17:30 and the power is cut off at 5 am. However, now, thanks to the automatic control system, it is possible to track each location. If the day is sunny and there is still a lot of light, you can delay the time to turn on the power or if it is cloudy, it can be closed earlier to flexibly ensure light for pedestrians.
According to HEPCO, the options to reduce lighting hours have been carefully calculated over many years of performing lighting tasks. Even if electricity prices have not yet increased, the company has also implemented solutions to save electricity in the dry season to reduce lighting costs for the budget.
In the summer, from 5 am, it is already bright, so there is no need to waste lighting. Similarly, in the afternoon, after 18pm, it will be completely dark, only then need lighting. Moreover, now a lot of families use solar electric bulbs to illuminate the gate, which is also a solution to contribute to public lighting and save electricity.
This is also one of the solutions that HEPCO deploys in mobilizing people to join hands in public lighting and reduce power consumption. Along with that, HEPCO is also gradually replacing traditional light bulbs with energy-saving filling bulbs. Implement projects to renovate and upgrade lighting in some central streets of the city. Hue, in the period of 2021-2025, install 1.450 sets of led lights, with a total cost of about 20 billion VND; project to replace 1.071 sets of led bulbs on central roads funded by the Luxembourg Government… It is expected that by 2025, lighting on main streets will reach 100%, of which LED lighting will reach 50%.
HEPCO leaders said that by applying the solution of adjusting lighting hours, alternating lighting ..., the unit has saved a large amount of power consumption, which also means a part of costs for the House budget. water. The replacement of LED bulbs alone saves electricity costs of nearly 200 million VND per year. In the near future, when the number of new LED lights reaches 50% of the total number of street lights, the cost of lighting will be reduced even more.
