Image source: Twitter/ Neoen El Salvador @NEOEN_SV Capella Solar, the 140-MW project involving two photovoltaic (PV) parks and battery storage facility that Neoen SA (EPA:NEOEN) is building in El Salvador, is more than 90% finished, the French company’s local unit has informed.

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 are battery costs expressed in $/kWh?

By expressing battery costs in $/kWh, we are deviating from other power generation technologies such as combustion turbines or solar photovoltaic plants where capital costs are usually expressed as $/kW. We use the units of $/kWh because that is the most common way that battery system costs have been expressed in published material to date.

Does battery storage cost reduce over time?

The projections are developed from an analysis of recent publications that consider utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.

Do longer duration batteries have a lower capital cost?

On a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 6 (left) also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 6.
