Building Energy Reliability in Adams County

About Birdseye Energy Storage
Birdseye Energy Storage is a 199MW Battery Energy Storage System (BESS) planned to support emission-less, cost-effective domestic energy for Adams County. The project will store electricity to deliver when it is most needed. The facility will increase regional grid reliability and lower blackout risk during high demand.
In addition to enhanced energy reliability, the project will create new local jobs during construction and operation, provide increased tax revenue to support essential services, support the county’s ability to control future energy costs, and contribute to community organizations through sponsorships and donations.
Current Project Phase
Birdseye Energy Storage is currently in the interconnection study process with Xcel Energy and in the permitting process with Adams County and in consultation with the City of Thornton. This phase includes comprehensive onsite diligence and application for all necessary approvals. Construction is anticipated to begin as early as 2027, with a commercial operations date planned for 2028 or 2029.

FAQs
Birdseye Energy Storage is a 199MW Battery Energy Storage System (BESS) planned for Adams County. The project will store low-cost electricity from the grid and send it back to the grid when it is needed most such as during times of high demand.
Adding energy storage to the electrical grid makes it more resilient and reliable, and can help facilitate the integration of zero-carbon resources like wind and solar. Energy storage projects also support Colorado’s goal of supplying 100% of electricity sales with zero-carbon resources.
Energy storage is generally very low-impact because it requires only a small land footprint, has no emissions, requires little water, and causes negligible traffic impacts. Birdseye Energy Storage is not expected to have significant impacts on local residents, the environment, or cultural resources.
Birdseye Energy Storage is strategically located on the grid to optimize energy delivery, reduce congestion-related price spikes, and deliver cost savings to families and businesses. The site selected for the project was based on a comprehensive review including environmental considerations, design constraints, and proximity to existing infrastructure.
The location where the power will enter the grid is a substation owned by Public Service Company of Colorado (Xcel Energy). The project location was chosen to ensure it benefits local families and businesses, regardless of the actual power traded on the market.
Decommissioning will be initiated if the entire Project has not operated for a period of up to three years, or when the Project has surpassed its useful lifespan. To ensure this commitment, the Project will obtain, for the benefit of Adams County, a bond from a creditworthy entity in an amount equal to one hundred percent (100%) of the estimated net costs to comply with applicable decommissioning and restoration requirements.
The location of the proposed Birdseye Energy Storage is being designed to minimize visual impacts. Neighboring properties will be visually shielded from the project by a combination of setbacks, visual barriers, natural features and native vegetation. As part of the design process, the Project has completed a series of visual simulations to further inform the site layout and visual mitigation plans.
Battery projects like the proposed Birdseye Energy Storage do not cause light pollution or otherwise impact dark skies. A limited amount of security lighting near the substation will be shielded, directed downward, and only used during a very limited amount of maintenance activities.
Yes. Safety is fundamental to all parts of the electrical grid, including battery energy storage. Because the project will be connected to the electrical grid, it will be subject to significant oversight and strict safety regulations that are frequently updated. The project will be monitored 24/7 by trained personnel prepared to maintain safety and respond to emergency events in coordination with local emergency responders as necessary. Our projects are equipped with proven monitoring technology and advanced safety design features, like sensors that monitor battery voltage, current, temperatures, and health, to ensure early detection and mitigation of issues.

Responsible Development
At every stage, from technology selection and engineering to construction, operation, and emergency preparedness, Birdseye Energy Storage prioritizes the safety of our facilities and our neighbors.
Birdseye Energy Storage has provided training to the South Adams County Fire Department and will continue to seek their input on the design and provide project-specific training as the project progresses.
