Profit per kw of energy storage

Should energy storage be shifted from abundance to scarcity?

Shifting the electricity they produce from times of abundance to times of scarcity is one of the most promising ways to allow for more renewables on the grid. With so many organizations, researchers, and governments interested in the benefits of energy storage the question shifts to how they balance value against the costs.

How much does PV cost per kWh?

By discounting cycles to a present value of 2.63 million kWh and applying that value, we get an LCOS for this cost component of 2.8 cents per kWh. Applying that value to the annual throughput results in total costs of $98,674 and PV costs equal to our target of $74,156.

How much will LCOE cost a second set of energy storage investments?

This could be a mistake though, because there is no more curtailed solar to charge the devices, which means that the LCOE for the second set of energy storage investments would be $0.04/kWh plus $0.06/kWh from charging with existing, dispatchable generators.

Is energy arbitrage profitable?

Because the driving factor behind the profitability of energy arbitrage, which is the buying of energy during low-price periods and selling it back during relatively higher price periods, is the spread between prices, not the sale price, LCOE becomes less meaningful in this context except in the case of a generation-storage hybrid plant.
