Investment cost estimation of large energy storage projects

How to promote energy storage technology investment?

Therefore, increasing the technology innovation level, as indicated by unit benefit coefficient, can promote energy storage technology investment. On the other hand, reducing the unit investment cost can mainly increase the investment opportunity value.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

What is the cost of energy storage?

The cost of energy storage varies by technology. According to a 2018 report by RedT Energy Storage, the cost of their Gen 2 machines starts at $490/kWh.

How many TWh of electricity storage are there?

Today, an estimated 4.67 TWh of electricity storage exists. This number remains highly uncertain, however, given the lack of comprehensive statistics for renewable energy storage capacity in energy rather than power terms.

What is the expected value of a second energy storage technology?

The expected value of the first energy storage technology, including the embedded option, is Φ 1 (P). In State (1,2), the second energy storage technology arrives with a Poisson process, and the firm invests in the second technology at the optimal time. The investment opportunity value of the second energy storage technology is F1,2 (P).

What is the investment benefit coefficient of energy storage technology?

Therefore, this study uses the unit annual peaking capacity of the energy storage system for the solution, that is, the investment benefit coefficient of the first energy storage technology is 140 (14,000 MWh/100 MWh).
