6 FAQs about [Cold storage energy storage peak and valley electricity price]

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.

How long do Valley electricity prices last?

For a valley electricity price of 0.0208 $/kW·h, the SPP ranges from 9.02 to 1.11 years, and for 0.0432 $/kW·h, it ranges from 5.16 to 0.82 years. Based on the peak-valley electricity prices in Xining and Shanghai, the SPPs are 4.62 years and 3.7 years, respectively.

What is a peak and Valley price policy?

The peak and valley price policy makes use of leverage to tap the potential of power generation and supply, enhance social and economic benefits, and achieve a reasonable distribution of costs. Fig. 12. Economic performance of ASU-CTES. In the ASU-CTES system, a larger peak-valley price difference brings in greater operating cost savings.
