Are battery energy storage systems worth the cost?Battery Energy Storage Systems (BESS) are becoming essential in the shift towards renewable energy, providing solutions for grid stability, energy management, and power quality. However, understanding the costs associated with BESS is critical for anyone considering this technology, whether for a home, business, or utility scale.
How do you convert kWh costs to kW costs?The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2022 value such that each projection started with a value of 1 in 2022.
How much does a 4 hour battery system cost?Figure ES-2 shows the overall capital cost for a 4-hour battery system based on those projections, with storage costs of $245/kWh, $326/kWh, and $403/kWh in 2030 and $159/kWh, $226/kWh, and $348/kWh in 2050.
Are battery storage costs based on long-term planning models?Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Does battery storage cost reduce over time?The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
