FAQS

Numerous studies done by assessors, real estate groups, and industry experts confirm that solar projects have no negative impacts on property values. Solar can even be beneficial because it is a quiet, passive and regenerative use of the land.

Please see the Property Valuation and Solar in Colorado Memo provided on the Resources page.

The project is working with the Lincoln County Road and Bridge department to ensure that impacts to public infrastructure are kept to a minimum and roads are adequately maintained. A detailed independent Traffic Study is being performed and the results will be posted here when it is complete.

This will be subject to an agreement to be developed with Lincoln County Road and Bridge. In general, construction traffic will be limited to areas designated through a Road Use Agreement with Lincoln County, as well as with schedules and penalties for violating the agreed-upon rules. Enforcement is likely to be a collaboration between the Lincoln County Sheriff’s Office and the project's general contractor.

A glare analysis for the project was completed prior to incorporating additional setbacks of solar arrays from residences. No glare hazards were identified for any residences or transit corridors. The solar modules use glass with an anti-reflective coating specifically designed to minimize glare hazards. As a result, modern photovoltaic (PV) modules reflect as little as two percent of incoming light, about the same as water and less than windows and many other common objects. To underscore this point, several major U.S. airports and military bases have installed solar modules at or surrounding airport facilities with no impact to pilots' visibility. General aviation would not be impacted, including crop dusting and medevac operations.

There are no chemical or liquid discharges associated with the normal operation of the project other than water used for dust control during construction and panel cleaning during operation. In addition, the project will utilize industry-standard spill prevention, control and countermeasure plans to ensure no contamination of local soils or watersheds occurs.

Federal policy directs us to source equipment from the U.S. where possible, yet we are technology agnostic in terms of Country origin.

Electrons flow to the closest loads, and the electric grid is highly interconnected between different utility companies and providers. The power will flow to the nearest connected loads, including Limon, Hugo, Lincoln County, Colorado Springs, and the rest of Colorado. Because local energy providers like KC Electric and Mountain View Electric in Lincoln County are a part of Tri-State, the energy produced by Ebba Solar may be used in part by local communities.

The project will utilize solar mounting structures that are able to accommodate the natural contours of the site without significant grading, which will minimize impacts and maintain the natural landscape as much as possible. The site will not be leveled except in certain small areas representing a tiny fraction of the total site for the placement of major equipment such as inverters, storage and other electrical equipment. The vast majority of the site will utilize steel piles driven directly into the native soil.

A detailed hydrology analysis has been performed to characterize flood zones and associated impacts. In addition, the project will comply with all applicable County, State and Federal stormwater and flood zone design regulations. In general, solar projects have a small impact on stormwater flows compared to other types of infrastructure given their preference for limiting impacts to natural contours and foundations mostly comprising small steel piles driven directly into the native soil.

After construction the project will be re-seeded with a blend of native grasses and forbs. Vegetation on site will be regularly maintained through a combination of mowing and/or grazing, and monitored for any erosion issues or invasive plants. The project has developed a re-vegetation plan that is available here.

Solar operations are a passive use of land and are significantly quieter than other potential land uses. The primary sound is from the inverters, which run only during daylight hours. The Massachusetts Clean Energy Center conducted a study of noise and inverters at utility-scale solar facilities running at optimum capacity and concluded that while solar projects do make some noise, that noise is negligible to begin with and becomes inaudible from between 50–100 feet of the facility’s boundary line. Given the 1000 ft. setbacks, there will not be audible noise at adjacent neighbor properties.

The primary fire suppression measure in the solar array areas will be vegetation management to control the amount of combustible material on site. There will be an Operations & Maintenance (O&M) plan that includes vegetation management requirements. The project will also work with the local fire districts to develop mitigation and response plans. In general, any response from local fire districts is not anticipated to include structure fire interventions inside the project fenceline beyond implementing containment measures to protect surrounding properties.

While some battery fires have occurred at other locations, there have been numerous advancements in technology and regulations that have made today’s batteries much safer, including a variety of preventative and monitoring tools, as well as a robust arsenal of built-in safeguards such as a fire suppression system, 24/7 monitoring, temperature sensors, gas detection, automatic ventilation, over-current protection and emergency shut-off panels. The project will comply with all local regulations, insurance requirements, and national code requirements in order to design the project in accordance with industry best practices to limit fire risks. The project will also work with local fire agencies to create a mitigation and response plan. In general, if a fire does occur, any response will be focused on containment.

Please see the Battery Energy Storage (BESS) Safety Fact Sheet provided on the Resources page.

The solar equipment itself is generally not flammable. Given the nature of the equipment, if a brush or prairie fire is impacting the project site, firefighting measures are likely to be limited to containment measures to protect adjoining lands and not involve significant volumes of water. The battery storage equipment is expected to have fire suppression equipment maintained on-site and integrated into the storage units.

During normal operation there is no risk of any chemical leakage from the batteries or PV site. Photovoltaic modules do not contain any liquid components. The battery, inverter and electrical equipment could include liquids for cooling such as ethylene glycol (anti-freeze) and non-toxic oils. The batteries contain a small amount of liquid electrolyte encapsulated in modules within larger overall enclosures. The risk of leaks from these systems is very low, and secondary containment will be utilized if indicated by local regulations and industry best practices. In general, the project will conform with all County, State and Federal regulations related to spills, including development of a Spill Prevention Control and Countermeasure (SPCC) plan, and containment measures for any materials stored or used on site (e.g., oil stored inside electrical transformers).

The project will use up to approximately 200-250 acre feet of water over the course of construction. All water sourcing will be augmented within the same water district. Compared to other electricity generation technologies solar photovoltaics require substantially less water.

During construction, water trucks will be used on site to minimize dust. Native soils will be left intact to the extent possible, and native grasses and forbs will be planted and maintained on the site during operations to minimize dust. Additionally, the operations team is keenly focused on minimizing dust to ensure optimal performance of the solar array during operations.

The project is in the Agricultural Zone. Solar and other renewable energy types are approved Special Review Uses for the Agricultural Zone and are governed by specific regulations adopted by Lincoln County for those technologies as memorialized in the County Zoning Regulations.

In general solar projects are best suited to less productive lands. The project has worked with its hosting landowners to identify lands with marginal agricultural value and no irrigation. Additionally, the project is considering incorporating potential “agrivoltaic” practices to benefit long-term soil health and the surrounding agricultural community which could include sheep grazing, pollinators, and other ecosystem services.

The project will be designed in accordance with all applicable requirements to support emergency access and the project will coordinate these designs with the local emergency services and fire districts. In general, 20 foot wide access roads to the substation and 16 foot wide roads within panel arrays are expected.

Solar modules will be no more than 12-15 foot high at max tilt, the project substation, adjacent to the Tri-State power plant, will have taller equipment where the project is connected to the grid.

The project has been designed to minimize viewshed impacts including meeting the county ordinance requirements of a minimum 1,000 foot setbacks from residences.

Heat Island research has proven that solar projects do not raise ambient temperatures outside of the project boundaries. The modules and surrounding air may get a few degrees hotter in the sun, but the effect is highly localized. The modules will return to ambient temperatures at night with no sustained heat effect that is characteristic of “heat islands.” Additionally, by converting a portion of sunlight into electricity (which is no longer available to heat the ground) and by shading the ground, PV arrays can cool rather than heat the ground surface, relative to uncovered land.  

See Resources page for more information.

The modules themselves generally run 30-50 degrees Fahrenheit higher than ambient air temperature in sunny conditions, (similar to how black plastic may feel sitting in the sunlight). However, the temperature of the modules has a very limited impact on the surrounding environment.

See Resources page for more information.

There are EMF emissions from solar plant equipment (e.g., module strings and inverters), but they are no different than those that we are exposed to every day from a variety of human-made and natural sources, including common household appliances and distribution lines. At the fenceline of a solar project, EMF emissions are comparable to ambient background levels, and much lower than many of the other sources we encounter on a daily basis.
