What is a stationary energy storage system?

In most cases, a stationary energy storage system will include an array of batteries, an electronic control system, inverter and thermal management system within an enclosure. Unlike a fuel cell that generates electricity without the need for charging, energy storage systems need to be charged to provide electricity when needed.

What was the energy grid like in Uruguay?

Uruguay's energy grid was powered almost exclusively by domestically created, renewable energy, and, adjusted for inflation, consumer prices had gone down. Today, there are more than 700 wind turbines installed across Uruguay's countryside. "It was absolutely a complete transformation," says Méndez Galain.

Which energy storage system is best for stationary energy storage?

Each system offers a unique set of advantages and challenges for stationary energy storage. On the other hand, batteries, an electrochemical system, may be the most well equipped for stationary ESS applications.

How many charging stations are there in Uruguay?

In May 2022, there were 89 charging stations and 122 chargers, distributed in most departments of the country. The electric vehicles sold in Uruguay have Type 2 connectors according to UNIT standards (UNIT – IEC 61851-1:2017 and UNIT - 1234:2016).

Are energy storage systems the future of energy storage?

While traditional power plants and interconnections will continue to be key levers to address this challenge, energy storage systems are projected to be the rising star in solving this flexibility challenge. Advancements in battery technologies and decreasing costs are the enablers behind the rise of stationary energy storage technologies.

Why does Uruguay generate a surplus of electricity?

Typically, Uruguay generates a surplus of electricity due to an excess of wind-power capacity. The country seeks to identify additional domestic uses for excess electricity and potentially increase exports to Argentina and Brazil.
