How long does a grid need to store electricity?First, our results suggest to industry and grid planners that the cost-effective duration for storage is closely tied to the grid’s generation mix. Solar-dominant grids tend to need 6-to-8-h storage while wind-dominant grids have a greater need for 10-to-20-h storage.
How does energy storage affect energy prices?As energy storage is added to the grid, the high July and December prices are reduced but prices in neighbouring months increase. In the 20 TWh scenario, average marginal prices for July, August, November, December and January range from 52 to 100 $/MWh while other months average 35 $/MWh or less.
How does long-duration energy storage affect marginal electricity prices?The total (a), regional (b), hourly (c), and monthly (d) distributions in the mean marginal electricity prices as the amount of mandated long-duration energy storage (in TWh) increases. Increases up to 20 TWh significantly decrease the variability in marginal prices while increases beyond 20 TWh have a lesser effect.
Does a zero-emissions western North American grid provide a value for long-duration storage?This study models a zero-emissions Western North American grid to provide guidelines and understand the value of long-duration storage as a function of different generation mixes, transmission expansion decisions, storage costs, and storage mandates.
How does energy storage affect marginal prices?This large variability in marginal price decreases as energy storage is added to the grid since energy storage shifts the costs of generation during periods of peak demand to periods of low demand. For example, with 20 TWh of storage, 99% of marginal prices drop below 130 $/MWh and only 32% of marginal prices are still at 0 $/MWh.
Do solar and wind dominant grids require different storage durations?Solar and wind dominant grids are expected to require different storage durations since solar has a diurnal cycle and wind might n
