How to understand the energy storage cost recovery mechanism

How do market mechanisms and regulatory frameworks affect energy storage cost recovery?

As illustrated through our two case studies, market mechanisms and regulatory frameworks have powerful impacts on energy storage cost recovery and asset profitability. Current regulatory treatment of an asset classifies it as generation, transmission, or distribution.

Can energy storage reduce the need for New Generation Investment?

Where capacity markets exist, storage can provide capacity similar to traditional generators, reducing the need for new generation investment. A study by Sioshansi et al. demonstrated that the capacity value of an energy storage device with eight hours of storage would nearly be equal to its rated capacity.

What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

Can energy storage improve power system economics and reliability?

Energy storage can improve power system economics and reliability by providing various market-remunerated and regulated services including, but not limited to, those listed in Table 1. It is important to note that storage can also provide consumer-related services (e.g., demand charge reduction), but these are not discussed in this article.

Are market and policy barriers affecting energy storage cost recovery & asset profitability?

With recently proposed optimization approaches increasing the technological feasibility of stacking energy storage services, market and policy barriers remain the primary challenges. As illustrated through our two case studies, market mechanisms and regulatory frameworks have powerful impacts on energy storage cost recovery and asset profitability.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
