Energy storage technologies provide for multiple applications(backup power, load leveling, frequency regulation, voltage support, and grid stabilization). Importantly, not every type of storage is suitable for every type of application, motivating the need for a portfolio strategy for energy storage technology. Energy storage technologies have recently been in the spotlight, discussed as essential grid assets. Though they can provide numerous grid services, there are a number of factors that restrict their current deployment. Typically, new energy storage deployments have relied on government financial assistance, but in a few cases, they may be the preferred economic alternative at current price points.
This report identifies the key barriers restricting further energy storage development and also includes a discussion of possible solutions to address these barriers. The most significant barrier to deployment is high capital costs. Though there are a number of regulatory and market barriers preventing the increased deployment of energy storage technologies, the primary barrier to deployment is high capital costs. Despite other barriers that exist, in most situations, this prevents a potential owner from creating a business case and further research is needed to decrease costs. Government, academia and manufacturers have an opportunity to play a key role here. Research should focus on reducing costs rather than improving marginal performance with the goal of a system that meets grid requirements at lowest possible costs. In addition to research focused on decreased storage system costs, additional initiatives aimed at opening market access for all resources to provide any services of which it is capable, should be implemented. Progress has been made in this effort, but much remains to be done and will require continued engagement from regulators, policy makers, market operators, utilities, developers and manufacturers. In this regards, A proactive regulatory intervention could be helpful in several areas to allow the emergence of new business models. This includes for instance the promotion of market access for aggregators which would allow for the participation of small scale electricity storage. Energy storage should be a well accepted contributor to realization of smart grid benefits

specifically enabling confident deployment of electric transportation and optimal utilization of demand side assets. It is expected that early deployments will be in high value applications, but that long term success requires both cost reduction and the capacity to realize revenue for all grid services storage provides. Energy storage has a great potential to be a major electricity system asset. However, it requires regulations that enable market access, and research that reduces costs. |
