Wärtsilä has been contracted to provide a project-critical energy storage system for the 50 MW Eolica Coromuel, S. de R. L (ECO) Wind Farm in La Paz, Mexico. The storage system is designed to deliver a power output of 10 MW for the operational life of the project. Wärtsilä is also providing a long-term service agreement, including maintenance, spare parts, repairs, remote monitoring and performance guarantees. The storage solution is to support ECO’s ability to meet grid code requirements.
ECO is owned by San Diego based Eurus Energy America Corporation, the majority owner of which is the Tokyo based global renewable energy company Toyota Tsusho Corporation. Eurus Energy America Corporation is part of the Eurus Energy Group.
ECO and the Wärtsilä energy storage system will be connected to the local grid controlled by the National Centre for Energy Control (CENACE), Mexico’s ISO. The system can control the facility’s ramp rate, in order to enhance generation reliability, as well as providing frequency control and capacity.
Wärtsilä’s GEMS smart energy management system will interface with and take instructions from the wind farm master controller.
“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. For this reason, we required an experienced supplier with an outstanding track record and Wärtsilä was, therefore, the obvious choice,” said Nick Henriksen, vp, Eurus Energy America.
