6 FAQs about [Calculation of energy storage peak and valley electricity price benefits]

Why is the peak-to-Valley electricity price gap widening?

As the share of renewable energy in the energy system increases, the peak-to-valley electricity price gap may widen due to the declining in the cost of renewable energy generation costs or narrow, or may narrow due to the increasing in grid dispatch costs .

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 Peak-Valley price ratio?

The peak-valley price ratio adopted in domestic and foreign time-of-use electricity price is mostly 3–6 times, and even reach 8–10 times in emergency cases. It is generally believed that when the peak-valley price difference transcends 0.7 CNY/kWh, the energy storage will have the peak-valley arbitrage profit space (Li and Li, 2022).

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.

When is energy storage charged & discharged?

Usually, the energy storage is charged at night when the price is at valley stage, and discharges during the daytime when the power consumption is at peak, so as to achieve peak-valley arbitrage and save cost.

What is economic benefit evaluation for energy storage?

The economic benefit evaluation for energy storage is an important part to investigate the feasibility of the project, which offers an essential basis for the scientific decision-making in the early stage of project implementation and provides the technical support for distributed energy storage system project investment.
