In northern regions, frequent haze forces us to save energy and reduce emissions. The best solution is to shift peak loads to valleys, storing heat during off-peak electricity hours and releasing it during peak hours when electricity prices are high. This not only helps save energy and reduce emissions but also lowers costs and increases corporate profits.
Using thermal oil to store energy up to 320°C, taking advantage of the off-peak electricity price from 0:00 to 8:00 AM, which is only 0.3-0.39 yuan per kWh. In contrast, the peak price from 7:30 AM to 12:00 PM is 1.39 yuan plus the standard price of 0.86 yuan, with an average price of 1.15 yuan. The profit between the two is 1.15 yuan - 0.39 yuan = 0.76 yuan.
In China, especially north of the Yangtze River, heating is required 24 hours a day in winter. This includes hotels, shopping malls, office buildings, commercial buildings, factories, etc.
Calculate its value:
1. The annual heating period is 120-180 days, averaging about 150 days.
2. The heat storage brick equipment is calculated at 2000 kW/h.
3. The profit per kWh is 0.76 yuan, minus the next day's operating cost of 0.06 yuan = 0.7 yuan/kWh.
4. From 0:00 AM to 8:00 AM, calculated as 8 hours.
