Components associated with battery systems, inverters, safety systems, and installation infrastructure necessitate expenses that lead potential smaller and medium-sized parties to walk away from an investment. The inability for smaller businesses and developing countries to access affordable financing offers additional market reluctance for investment.

Battery Degradation and Limited Lifespan

• Batteries will slowly lose performance over time as they experience repeated cycles of charging and discharging. Decreased performance leads to added costs of operations due to the requirement of replacing or refurbishing a battery system once it reaches a certain life span. Life cycle concerns in the form of lifespan, re-usability, and performance reliability of a battery system makes certain grid operators and investors remain cautious about investing in a large-scale battery energy storage system.

Market Opportunities

Rising Demand for Electric Vehicles (EVs)

• The rapidly developing EV market is reinforcing the broader ecosystem for battery manufacturing, which concurrently benefits the BESS industry. Mass production of EV batteries enables technology advancement. It decreases total costs of battery production, thereby creating a pathway for more cost-effective and higher performance energy storage solutions and added revenue opportunities in battery reuse and second-life applications.

Development of Microgrids and Smart Grids

• The increased investment in microgrids and smart grid systems brings strong growth opportunities to the BESS market. BESS play a critical role to decentralized power systems by providing back-up power, furthering energy efficiency, and enabling demand response. As urban settings, remote communities, and industrial sites expect to achieve energy independence and reliability, demand for a package of integrated storage solutions is expected to increase.
