AES is deeply committed to working with the community, area leaders, policymakers and regulators to responsibly develop and operate all of our clean energy projects. Our strategic approach is to engage early and often with local stakeholders to share information about the project and most importantly, gather feedback to address issues that may arise. This proactive approach to stakeholder engagement is intended to ensure the local community’s questions and concerns are addressed and enable timely approvals.

Environmental and technical studies

AES’ National Grassland solar project was studied extensively and carefully planned to have no negative impact on regulated habitats, threatened and endangered species or cultural/historical resources. AES is conducting ongoing consultations with Colorado Parks and Wildlife and U.S. Fish and Wildlife Service to ensure the sanctity of the land.

Community engagement

AES is committed to being a good neighbor to the Baca County community. We value our relationships with local partners and community members, and we work diligently to maximize the positive impact our clean energy projects have on local communities. Our projects are intentionally developed to create lasting positive benefits for landowners and to create significant economic opportunities in the community over the life of the project, without burdening existing infrastructure.

This is why we collaborate with a broad cross section of community leaders from government, local businesses, education, social services and residents to identify opportunities where AES can provide financial support, volunteerism and other types of partnership to support high-impact initiatives, programs and institutions in the local communities.
