Finnish technology group Wärtsilä is to provide a "project-critical” lithium-ion battery energy storage system for a 50MW wind farm in Mexico.

A Wärtsilä spokesperson told World Battery News the GridSolv Max BESS is designed to deliver a power output of 10MW for the operational life of the Eolica Coromuel, S de R L (ECO) wind farm in La Paz – which is owned by San Diego-based Eurus Energy America Corporation.

The commissioning date for the BESS is expected in the summer of this year, the spokesperson said.

Eurus’ majority owner is the Tokyo-based global renewable energy company, Toyota Tsusho Corporation.

Smart storage

Eurus Energy America VP Nick Henriksen said: "This project will help Mexico meet its renewable energy goals, and efficient energy storage is a key element for its success. The Mexican government is to have 30% of energy generated by renewables by 2021 and 35% by 2024.”

The order marks an expansion of Wärtsilä’s smart storage technology to the region. The company is also providing a long-term service agreement for ECO, including maintenance, spare parts, repairs, remote monitoring and performance guarantees.

ECO and the BESS will be connected to the local grid controlled by the National Center for Energy Control, Mexico’s independent system operator. Wärtsilä’s ‘GEMS’ smart energy management system will interface with and take instructions from the wind farm master controller.
