6 FAQs about [Investment ratio of wind solar and storage]

Do storage technologies add value to solar and wind energy?

Some storage technologies today are shown to add value to solar and wind energy, but cost reduction is needed to reach widespread profitability.

How to maximize the value of a solar or wind plant?

We first present the results of optimizing the discharge behaviour of a solar or wind plant combined with storage, for a fixed storage size, to maximize the revenue of the plant. We then optimize the storage size to maximize the value of the plant, where value is defined as the ratio of the plant revenue to the plant cost.

How does energy storage affect the selling price of solar energy?

The average selling price without storage is lower for wind than solar, but as the energy storage increases in size (per unit rated power of solar or wind generation), the pricing distribution and mean selling price become increasingly similar across the two energy resources (Supplementary Figs 6–8).

Do solar photovoltaic (PV) storage technologies reduce EROI ratios?

All storage technologies paired with solar photovoltaic (PV) generation yield EROI ratios that are greater than curtailment. Due to their low energy stored on electrical energy invested (ESOI e) ratios, conventional battery technologies reduce the EROI ratios of wind generation below curtailment EROI ratios.

Is solar storage more valuable than wind?

Storage is more valuable for wind than solar in two out of the three locations studied (Texas and Massachusetts), but across all locations the benefit from storage is roughly similar across the two energy resources, in terms of the percentage increase in value due to the incorporation of optimally sized storage.

What is the power to energy cost trade-off of storage technologies?

The power to energy cost trade-off of storage technologies is also similar across the two energy resources. This means that the direction of optimal improvement in energy and power costs is similar across the three locations and two energy resources for any given storage technology.
