The factors that restrict energy storage are

Why is energy storage a barrier to deployment?

Though they can provide numerous grid services, there are a number of factors that restrict their current deployment. The most significant barrier to deployment is high capital costs, though several recent deployments indicate that capital costs are decreasing and energy storage may be the preferred economic alternative in certain situations.

What is a barrier in energy storage?

The term barrier, as used in this report, is broadly defined as an issue that hinders deployment of energy storage technologies. In some instances, a barrier may prevent deployment; and in others, it may limit deployment, limit revenue or limit consideration for deployment.

Should energy storage resources have their own functional classification?

number of commenters in the FERC NOPR on cost allocation suggest that energy storage resources should have their own functional classification. This echoes calls for a different classification since the renewal of interest in energy storage technologies.

Are energy storage systems a generating entity or a controllable load?

separate barrier to deployment, but relevant to the asset classification topic, exists in ERCOT. Current market rules require that an energy storage system register as both a generating entity and as controllable load.

What are the different types of energy storage barriers?

The barriers are broadly categorized into regulatory barriers, market (economic) barriers, utility and developer business model barriers, cross-cutting barriers that cross the different categories, and technology barriers specific to energy storage technical performance and capabilities.

Why is energy storage a problem?

The lack of direct support for energy storage from governments, the non-announcement of confirmed needs for storage through official government sources, and the existence of incomplete and unclear processes in licensing also hurt attracting investors in the field of storage (Ugarte et al.).
