6 FAQs about [Energy storage costs and peak-valley electricity price differences]

How much does electricity cost in a valley?

Table 1 shows the peak-valley electricity price data of the region. The valley electricity price is 0.0399 $/kWh, the flat electricity price is 0.1317 $/kWh, and the peak electricity price is 0.1587 $/kWh. The operation cycles (charging-discharging) of the Li-ion battery is about 5000–6000.

What is the difference between Peak-Valley electricity price and flat electricity price?

Among the four groups of electricity prices, the peak electricity price and flat electricity price are gradually reduced, the valley electricity price is the same, and the peak-valley electricity price difference is 0.1203 $/kWh, 0.1188 $/kWh, 0.1173 $/kWh and 0.1158 $/kWh respectively. Table 5. Four groups of peak-valley electricity prices.

How many provinces have a peak to Valley electricity price difference?

The State Grids and China Southern Power Grids of 29 provinces, autonomous regions and municipalities announced the electricity tariffs for industrial and commercial users in December 2021. According to the statistics, 14 provinces and cities have a peak to valley electricity price difference that exceeds 0.7 yuan/kWh.

Can user-side energy storage projects be profitable?

At present, user-side energy storage mainly generates income through the arbitrage of the peak-to-valley electricity price difference. This means that if the peak to valley price difference is higher than the levelized cost of using storage (LCUS), energy storage projects can be profitable.

What happens when electricity price is high?

When the electricity price was high, the ESS discharged to the power grid, and the ESS obtained income through the price difference of energy storage and release. Dufo-López R. based on the Spanish electricity market to optimize the size and control of a grid-connected private ESS.

Does energy storage contribute to peaking shaving and ancillary services?

Conclusions Energy storage can participate in peaking shaving and ancillary services. It generates revenue though electricity price arbitrage and reserve service. The BESS's optimization model and the charging-discharging operation control strategy are established to make maximum revenue.
