Project Overview

The 100 MW / 400 MWh Oso Negro Energy Storage facility will provide energy and capacity services to the local grid, enhancing grid reliability and accelerating the integration of locally produced renewable energy. The project will abide by the most stringent design and safety standards to ensure the project maximizes benefits to Tri-State and the City of Albuquerque.  

Construction of the Oso Negro facility is anticipated to start in late 2026. The 2028 completion of the facility will ensure that Tri-State meets its reliability needs and contributes to its goal of 70% clean energy resources by 2030.   

Situated along a major transmission corridor feeding the West Mesa substation, the site will have no adverse environmental impacts. Oso Negro’s site location is optimal for new energy infrastructure as it does not require long transmission lines to connect the facility to the power grid and is complementary to surrounding land uses.
