Since the start of electricity supply from Zhuhai to Macao on July 1, 1984, the China Southern Power Grid has delivered over 20 billion kilowatt-hours (kWh) of power to the region as of December 20, 2012. The total reached 200.03 million kWh, with an estimated 3.85 billion kWh supplied in 2012 alone—an increase of 21.6% compared to the previous year. This represents more than 20 times the power supply level at the time of Macao's return in 1999, and accounts for nearly 90% of Macao’s total electricity consumption.
The China Southern Power Grid has always placed a high priority on ensuring stable power delivery to Macao. Over the past 29 years, it has maintained a 100% power supply reliability for transmission to the region, playing a crucial role in supporting Macao's political stability and economic growth. To achieve this, several key strategies have been implemented.
First, the grid has significantly expanded its power transmission infrastructure. It completed the construction of a two-circuit 110 kV line connecting Nanao and Gongao for power supply to Macao. In addition, a new 220 kV double-circuit (cable) line between Zhuhai Qinyun and Lotus was commissioned this year. Today, the power supply network to Macao consists of five 220 kV lines as the main channels, along with four 110 kV lines serving as backup, forming a "double insurance" system. This has increased the power supply capacity to 900,000 kW.
Second, regular maintenance and operational improvements have been carried out. A cross-border repair mechanism has been established with the Macau Electric Power Company, and various cultural exchange activities are held to enhance cooperation and communication. These efforts ensure the safe and stable operation of the power transmission lines.
Third, a normalized protection mechanism has been set up, with regular joint anti-accident drills conducted to guarantee power security during major events in Macao. Through these measures, the China Southern Power Grid continues to support Macao’s development and ensure a reliable and uninterrupted power supply.Led grow light provide the following value in the agricultural and horticultural industries:
1. Provide light: indoor grow lights can provide the light required by plants, especially in the indoor planting environment, which can make up for the lack of natural light. This is important for the agriculture and horticulture industry, as light is a key factor in plant photosynthesis, which promotes plant growth and development.
2. Control spectrum and photoperiod: grow lights led can adjust the color and intensity of light to meet the light needs of different plants at different growth stages. For example, during the germination and flowering of plants, providing the appropriate spectrum and photoperiod can promote plant growth and flower fruit production.
3. Increase yield and quality: The use of plant lights can extend the growth time of plants and improve the yield and quality of plants. By controlling light conditions, photosynthesis and nutrient absorption of plants can be promoted, thereby increasing crop yield and improving the quality of agricultural products.
4. Energy saving: Compared with traditional agricultural planting methods, Led grow lights can use light energy more effectively and reduce energy consumption. grow lights can provide suitable light according to the needs of plants and avoid waste of energy.
5. Expand the scope of planting: The use of plant lights can free the agricultural and horticultural industries from the limitations of the natural environment and can be planted indoors or in a soilless culture environment. This can expand the range of cultivation and increase the availability and diversity of agricultural products.
In short, growth lights can provide important value in the agricultural and horticultural industry, such as light, spectrum and photoperiod control, increase yield and quality, save energy and expand planting range.
