Utility scale ESS cost vs benefit calculation in Mexico

What are the costs and benefits of ESS projects?

Costs and benefits of ESS projects are analyzed for different types of ownerships. We summarize market policies for ESS participating in different wholesale markets. Energy storage systems (ESS) are increasingly deployed in both transmission and distribution grids for various benefits, especially for improving renewable energy penetration.

What are future cost projections for utility-scale Bess?

Projected Utility-Scale BESS Costs: Future cost projections for utility-scale BESS are based on a synthesis of cost projections for 4-hour duration systems as described by (Cole and Karmakar, 2023). The share of energy and power costs for batteries is assumed to be the same as that described in the Storage Futures Study (Augustine and Blair, 2021).

Does ESS affect electricity price?

The supply curve in the New York Independent System Operator (NYISO) day-ahead energy market is modeled to evaluate the impact of ESS on electricity price. The operation and degradation cost is, however, set to be $1/MWh, which is significantly less than the practical cost .

What are base year costs for utility-scale battery energy storage systems?

Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.

What factors affect the cost of a Bess system?

Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.

How can utilities benefit from a Bess system?

Utilities can benefit from installed BESS in two aspects. First, BESS can contribute to the secure and economic operation of the electric grid, especially with high penetration of renewable energy. Second, BESS can participate in the wholesale competitive markets to generate revenues for utilities.
