DOE’s Energy Storage Grand Challenge supports detailed cost and performance analysis for a variety of energy storage technologies to accelerate their development and deployment The U.S. Department of Energy’s (DOE) Energy Storage Grand Challenge is a comprehensive program that seeks to accelerate.
Each year, the U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U.S. solar photovoltaic (PV) systems to develop cost benchmarks. These benchmarks help measure progress toward goals for reducing solar electricity costs.
Let's cut through the industry jargon - when we talk about battery storage costs per MW, we're essentially asking: "How much does it cost to park a lightning bolt in a box?" The short answer? About $1.2 million for a 4-hour lithium-ion system. But like any good tech story, the devil's in the detail.
In 2025, with lithium-ion battery prices dancing around $0.32 per watt-hour (thanks to those oversupplied Chinese factories) [1], understanding storage economics isn’t just for engineers anymore. It’s become as essential as knowing your morning latte price. Think of a modern battery storage system.
Buyers typically pay a broad range for utility-scale battery storage, driven by system size, chemistry, and project complexity. The price per kWh installed reflects balance of hardware, permitting, and integration costs. Cost also hinges on duration, interconnection requirements, and regional labor. How to calculate power storage costs per kWh?In order to accurately calculate power storage costs per kWh, the entire storage system, i.e. the battery and battery inverter, is taken into account. The key parameters here are the discharge depth [DOD], system efficiency [%] and energy content [rated capacity in kWh]. ??? EUR/kWh Charge time: ??? Hours.
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.
What is a good round-trip efficiency for battery storage?The round-trip efficiency is chosen to be 85%, which is well aligned with published values. 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.
How do I calculate energy storage based on cost lines?You can add all of the cost lines together (in $) and divide them by the total power rating in kW (yielding a $/kW metric). Or you can add all of the cost lines together (in $) and divide them by the total energy storage in kWh (yielding a $/kWh metric).
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.
Why did we choose a 100 MWDC PV system?We chose a 100-MWdc PV system because that was the approximate average size of U.S. utility-scale systems reported in EIA (2022). The per-unit cost results are meant to be generally applicable to systems with PV sizes between about 50 and 200 MW
