Office building energy storage cost vs benefit calculation in Mexico

How does cost of storage affect LCOE?

As the fraction of electricity that is directly consumed decreases and the fraction of electricity that is stored beforehand increases, the impact of the cost of storage per energy throughput (also called levelized cost of storage or LCOS) on the LCOE increases. For renewable energy shares above 70%, long term storage is required.

What is levelized cost of Storage (LCOS)?

The common method for this is to use the levelized cost of storage (LCOS) approach, where a cost is assigned to storing and releasing a defined amount of energy (e.g. one kWh or one MWh) in a certain application without consideration of the actual size of the ESS.

Is electrical energy storage system use case a source of revenue?

An Electrical Energy Storage System use case for the capacity component only exists if a capacity component was awarded in the auctions. Therefore, no revenue can be generated from the results of the 2015 auctions due to a lack of awarded capacity bids. However, capacity is a possible source of revenue from the 2016 and 2017 auctions.

Should electrical energy storage systems be used in long-term power auctions?

As being generally technology-agnostic, the use of Electrical Energy Storage Systems (EESS) within the long-term power auctions was neither explicitly encouraged nor discouraged. This analysis assumes that the EESS, more specifically the BESS, would be part of a solar PV plant.

Can a capacity component be used for electrical energy storage system?

These bids included PV plants, wind power plants and geothermal generators. An Electrical Energy Storage System use case for the capacity component only exists if a capacity component was awarded in the auctions. Therefore, no revenue can be generated from the results of the 2015 auctions due to a lack of awarded capacity bids.

What is the optimum Bess energy configuration?

Analyze the commercially optimum BESS active power and nominal energy configuration, within ranges up to 15 MW and 100 MWh. Financial modeling and sensitivity analysis of the three selected BESS technologies.
