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.

What are battery cost projections for 4 hour lithium-ion systems?

Battery cost projections for 4-hour lithium-ion systems, with values normalized relative to 2022. The high, mid, and low cost projections developed in this work are shown as bolded lines. Figure ES-2.

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.

Will higher capacity prices boost the business case for new power generation?

Source: Lawrence Berkeley National Laboratory (Berkeley Lab) Purchase Licensing Rights Higher capacity prices boost the business case for new power generation as well as keeping existing fossil fuel plants online, Brynna Foley, Associate, Research at data provider Enverus, told Reuters Events.

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 long-term power purchase agreements affect prices?

The price of long-term power purchase agreements (PPAs) with commercial offtakers and utilities are influenced by a number of drivers and developers will factor in capacity payments over a longer period when negotiating prices, Foley noted. However, the auction highlighted the tightness in the market.
