Energy storage electricity fee profit analysis table

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.

How do you calculate energy price for charging in year N?

To simplify the equation, let E p r i c e n be the energy price for charging in year n, described by E p r i c e n = e p r i c e (1 + r e p) n.

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.

How much does a LCOE cost?

The LCOE may be calculated at $0.04/kWh for the energy storage device and $0.06/kWh for the generator. Imagine that a year later, during the permitting and planning process, the decision maker reads a report that says the system is expected to need 20MW of firm capacity in the near future.

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.

Should LCoS show how much cost is added to electricity?

1. LCOS should show how much cost is added to electricity by storing it This criteria is satisfied by the DAYS formula and the proposed formula. While the document, where the DAYS formula was first published, claims the units are $/kWh-cycle, this is not correct (ARPA-E, 2018).
