Jupiter Power is proposing to build and operate the Spruce Summit Energy Storage Facility (Spruce Summit) in Hayden, Colorado. Spruce Summit is a proposed 400-megawatt utility-scale battery energy storage project that is expected to connect to the existing Mt. Harris substation near Hayden Station. The project represents an approximately $500 million investment in Northwest Colorado’s infrastructure.
Project Location
Spruce Summit Energy Storage will be located off County Road 51, less than a mile west of Hayden Station. The generation tie-line will run across utility property, near existing transmission lines, to interconnect at the Mt. Harris substation. In the photo, the green lines represent the outline of the site’s property lines, while the area shaded in blue is the actual project footprint.

Project Status
The project is currently in the outreach and permitting phase, and is applying to Hayden & Routt County for land use permits.
The Jupiter Power team hosted a community open house at the Hayden Center on June 11th from 3 to 7 p.m. If you missed the open house, a virtual presentation can be found on our FAQ tab.
Pending successful permitting, Spruce Summit is anticipated to begin construction in 2027 and begin operating in late 2028.
Further updates to project schedules will be posted on this website.

Community Benefits
The Spruce Summit Energy Storage Project will benefit residents and businesses by bolstering the power grid and supporting the local economy.
- Spruce Summit will bring an approximately $500 million investment to Hayden & Routt County on only 30-40 acres of property
- The Project is expected to pay over $1.5 million in local taxes annually.
- At peak construction, the project will create approximately 200 construction jobs, and an estimated six full-time technical positions for ongoing operations. Local residents are preferred and encouraged to apply for these positions.
- The projects will improve the reliability, stability, and resiliency of the regional power grid
- Jupiter Power is committed to being a long-term member of the community and hopes to find ways to contribute meaningfully to the local community above and beyond the benefits mentioned above.

Project Safety
At Jupiter Power, safety is our top priority—for the community and for our team—through every stage of the project. During normal operations, Spruce Summit will not produce fumes, pollution, odor, dust, or other off-site impacts to those nearby.
Jupiter Power uses only standardized, lab-tested and approved equipment, complies with all National Fire Codes, including standards specifically governing energy storage, and specifically engineers our projects so that in the extremely unlikely case of an equipment malfunction, any resulting event can be managed safely. To make that possible during operations:
Jupiter Power uses only standardized, lab-tested and approved equipment, complies with all National Fire Codes, including standards specifically governing energy storage, and specifically engineers our projects so that in the extremely unlikely case of an equipment malfunction, any resulting event can be managed safely. To make that possible during operations:
- Each battery module is monitored 24/7 and is equipped with sensors, fire suppression systems and alarms.
- Every battery is individually tracked by advanced software to catch problems early.
- Enclosures are spaced deliberately to ensure that any potential fire would stay contained within a very limited area of the projects.
- The projects will be built to meet national Fire Code standards and will be tested to strict safety protocols developed by Underwriters Laboratories (UL), the world’s leading safety testing organization.
Jupiter has met with the West Routt Fire Protection District and will work closely with them and other emergency responders throughout the process of the projects' design. Jupiter looks forward to continuing that coordination throughout the life of the projects, offering fire safety training opportunities and resources to support preparedness.
Bottom line: Spruce Summit is designed with the highest safety standards, using cutting-edge technology, and with ongoing coordination with local first responders to ensure safe and responsible operations.

Why battery storage?
- Getting more from our existing grid:
By charging when there is more power available on the grid than needed to meet demand, and then shifting that supply to when it’s needed most, energy storage helps us get more out of the power grid we already have, potentially reducing the need for new power plants and power lines. - Customer demand:
Homes and businesses need reliable energy at all times. Morning and evening hours are typically when the largest amount of energy is needed from the grid to serve customers. During these times, we can pull energy from batteries to meet the high demand when other sources of power would be more expensive or unavailable. - Maintain stability:
Supply and demand of energy fluctuate throughout the day and sudden changes in either can affect grid stability. Batteries can act much faster than other power sources to help even out the fluctuation of energy on the grid, helping to ensure that our power supply remains stable.
