The frequent smog in northern regions forces us to save energy and reduce emissions. The best solution is to shift peak load to valley periods, 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 heat up to 320°C, and utilizing the off-peak electricity price from 0 AM to 8 AM, which is only 0.3-0.39 yuan per kWh. However, from 7:30 AM to 12:00 PM, the peak price is 1.39 yuan plus the flat price of 0.86 yuan, making the average electricity price 1.15 yuan. The profit between the two is 1.15 yuan - 0.39 yuan = 0.76 yuan.
In our country, especially in areas north of the Yangtze River, heating is required 24 hours a day during winter. For example, hotels, shopping malls, office buildings, office spaces, factories, etc.
Let's calculate its value:
1. The heating period is 120-180 days per year, averaging around 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, resulting in 0.7 yuan per kWh.
4. From 0 AM to 8 AM daily, calculated as 8 hours.
