Supporting Adams County
By engaging local stakeholders, supporting economic development and aligning with community-driven philanthropic goals, we aim to create projects that not only generate renewable energy but deliver meaningful long-term benefits to the people and places we serve. Since 2023, we have contributed more than $900,000 to local schools and non-profits across the United States.
Lightsource bp believes that the success of our projects begins with building strong, lasting partnerships with local partners. If you are part of a local organization that would like to learn more about our community giving, please contact our Community Relations Managers at uscommunityrelations@lightsourcebp.com.

How solar farms work
Solar farms add energy to the local electric grid, just like other electric power plants. Rows of solar panels produce the electricity, which flows through the grid to power places like homes, businesses, schools and hospitals.
Solar panels are mounted on structures called racking. Racking sits on posts that raise the panels above the ground. The posts take up less than 5% of the land. With significant open space under the panels, in the rows and in buffer areas to plant site-specific grasses and other vegetation, we set a goal of increasing biodiversity in the first 5 years of operation. We also integrate agriculture where practical.
The racking is equipped with smart solar trackers that slowly and quietly rotate throughout the day, following the sun to maximize solar energy production. These smart trackers serve other important purposes, too: they help protect solar panels from hailstorms, high winds and buildup of snow on solar panels.
Best practices for solar development
Lightsource bp has a deep commitment to delivering safe and affordable renewable energy, as well as maximizing the environmental sustainability and positive social impacts of our projects. We are intentional with every detail, from the fencing we choose to the vegetation we plant. We want our sites to be great additions to the local community.
Environment and aesthetics
- Adding buffer zones of greenspace with trees and shrubs between the solar panels and public view.
- Installing game fencing— consistent with the local aesthetic of the area—around the project, as opposed to industry-standard chain link fencing.
- Planting vegetation under and around the solar panels, with a seed mix customized for the local area. These seed mixes help to increase biodiversity and improve soil health.
Planning for lifetime success
- Developing a comprehensive drainage and traffic management plan, working directly with the county on road use agreements.
- Budgeting for consistent maintenance and upkeep of the facility.
- Preparing a decommissioning plan to ensure to ensure the safe, efficient and environmentally responsible removal or repurposing of equipment and facilities.
- Committing to recycling solar panels.
Making a local impact
A solar farm is so much more than energy production. It can boost biodiversity on the land. It can provide new tax revenue to your community. It’s a new, year-round type of harvest for your neighbor farmers that helps them keep their land for future generations.
Long-term benefits
In addition to generating affordable, renewable energy, home-grown solar has several long-term benefits, including:
- Rest and regeneration of the land during the project’s life, improving soil health and preserving it for future use.
- Healthy groundcover under and around the panels that boosts local biodiversity, creating a stable, long-term home for plants, pollinators, birds and other wildlife.
- Opportunity for integrated agriculture such as sheep grazing or bee keeping.
- Rural resilience through continued local ownership of the land with long–term lease payments.
Economic growth for the community
- Big Bronco Solar and Storage represents a $675 million private investment into home-grown, affordable energy for Colorado.
- Throughout its life, Big Bronco Solar and Storage will contribute up to $39 million in estimated revenue to the local tax base, benefitting local school systems and many other community public services.
- During peak construction, Big Bronco Solar and Storage is estimated to create approximately 400 jobs.
- Lightsource bp is committed to supporting philanthropic activities and charitable donations to local organizations.
