Can a battery energy storage system complement a PV plant in Mexico?

An analysis was carried out to verify if it would be commercially feasible to operate a Battery Energy Storage System (BESS) to complement the operation of a PV plant in the Mexican market. This PV plant would generate a revenue through the contracting via the 2015, 2016 or 2017 LTAs in Mexico.

How much energy will Mexico produce by 2022?

By 2022, the company plans to increase clean energy generation to 2,342 gigawatt hours, equivalent to powering 1.42 million homes and meeting the energy needs of 5.1 million people, while avoiding about 1,018,882 tons of carbon dioxide emissions, contributing to environmental protection and sustainable development in Mexico.

How much does a power plant cost per MW?

This value is in line with typical market conditions worldwide, where the contracted operation of such services is typically between 150,000 USD and 400,000 USD (3 to 8 million MXN) per MW and year.

How much power does a battery energy storage system use?

A typical Battery Energy Storage Systems in standby only consumes between 0.5 – 2% of its nominal power (e.g., a BESS with a nominal power of 1 MW would have an average auxiliary power consumption of 5 kW - 20 kW) and can be started from the “cold” ofline state to the “hot” running state within 5 seconds or less

Why do we need energy storage?

The current main driver for the need for energy storage is the fact that renewable energies in general, and particularly photovoltaic and wind power plants (variable Renewable Energies – vRE), are increasingly entering the electricity market whilst displacing conventional technologies.
