About The Project

Birdseye Energy Storage is a 199 MW 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 a more reliable and resilient local energy system that can help moderate future energy costs, and contribute to community organizations through sponsorships and donations.

Current Project Phase

  • Phase 1: Permitting & Compliance

    Birdseye Energy Storage is currently progressing through the interconnection study process with Xcel Energy, the permitting process with Adams County and in ongoing consultation with the City of Thornton. This phase includes comprehensive onsite diligence and application for all necessary approvals. Following the completion of this process, construction is anticipated to begin in 2028, with a commercial operations date planned for 2029.

  • Phase 3: Operations

Project Benefits

Economic

Birdseye Energy Storage is committed to supporting the local workforce by creating opportunities for stable, well-paying jobs during the construction and maintenance of the project.

Birdseye Energy Storage will generate significant tax revenue that will benefit local schools, infrastructure, and community services without adding pressure on other governmental services.

Community

As part of the project’s commitment to being a good neighbor, Birdseye Energy Storage has established a quarterly community giving program that supports community-based organizations. Birdseye Energy Storage also plans to create local scholarship opportunities once the project is operational.

Energy

Aging transmission grids and inefficient power systems are costing us more money each year. Energy storage projects like the proposed Birdseye Energy Storage project will help manage future energy cost volatility, reducing the burden on local families and businesses. By storing energy for use during periods of high demand, the project will help reduce reliance on less efficient generation facilities and support the electrical grid without the need for some costly transmission problems.

Sustainability

Energy storage is a critical part of building a reliable, affordable, and increasingly clean energy system.

America’s electric system is in the midst of a technological transformation. Infrastructure and generation built before the computer age is retiring. Zero-emissions power sources are being built at unprecedented scale, replacing fossil fuel generation. Transportation and industrial sectors are swapping fuels for electricity. Energy storage helps bridge the gap between when electricity is generated and when it is needed, turning intermittent clean energy into dependable power when homes and businesses need it most.

Flexible & Responsive

When charged during periods of excess solar, wind, or hydropower generation and discharged at times of high demand otherwise served by fuel-based generation, energy storage maximizes the use of renewable energy and reduces the carbon intensity of the power system. As storage provides more flexibility to the power system, fuel-based resources can also run less frequently and more efficiently, reducing emissions further.

By storing electricity when it is abundant and delivering when it is needed most, energy storage helps the grid adapt to changing conditions throughout the day.

Batteries are the fastest resource on the grid, providing electricity instantaneously in response to sudden changes in demand or disruptions to supply. In a future with more renewables and increasingly extreme weather, quick ramping from storage will ensure continuity of service.

As renewable energy grows and extreme weather becomes more frequent, energy storage’s rapid response will be essential to maintaining reliable, continuous service. The ability to respond in seconds to changing grid conditions makes energy storage an essential tool for supporting the evolving demands of the power system.

GridStor has demonstrated this capability during a real grid emergency. In November 2024, Goleta Energy Storage was dispatched to help keep the region powered when wildfire-related shutoffs compromised local infrastructure, demonstrating how battery storage can support continuity of service during extreme conditions.

Boosting Domestic Energy Supply

Birdseye Energy Storage directly supports efforts to increase national security and boost domestic supplies for our energy needs. After decades of relatively little change, U.S. energy consumption is forecasted to grow significantly through 2050, primarily resulting from the adoption of artificial intelligence and increased U.S. manufacturing. Birdseye Energy Storage is a resilient, clean, and cost-effective solution to an increasing demand for reliable domestic energy.

Supporting Adams County

Birdseye Energy Storage supports community-based organizations and nonprofits serving Adams County.

As GridStor becomes a community member of Adams County, we look forward to continuing to support organizations that enhance the community and provide valuable resources to its residents such as the Northglenn-Thornton Rotary Club, Adams County Fair, the Adams 14 Education Foundation, and the South Adams Fire Fighters Association that enhance the community and provide valuable resources to its residents.

Once the project is operational, the existing Community Giving program will be converted to a scholarship program to support students preparing for the jobs of tomorrow.
