    National Grassland solar project

    National Grassland solar project

    AES’ National Grassland solar-plus-storage project is a planned clean energy facility that will incorporate the most advanced solar and energy storage technologies. The project is designed to minimize impact on the local environment and will support Colorado’s clean energy goal of 100% renewable energy by 2040.

    Project overview

    Power generation icon

    199 MW solar plus 100 MW storage capacity


    Enough clean energy to power 71,739 homes annually


    Baca County, Colorado, off Hwy 116

    Project overview

    • 1,120 acres of privately owned land will host the project

    • Provides clean energy to Xcel Energy customers

    • 2025 estimated operational date

    • Up to 25-year project life with AES as long-term owner operator


    AES’ National Grassland project will deliver both environmental and economic benefits to the citizens and communities of Baca County. The project site consists of flat, vacant land with limited agriculture.

    Expected economic benefits include new tax revenue and 300 local jobs during construction and operations

    • 520,250 MWh of carbon-free electricity each year

    • 406,400 tons of CO2 emissions expected to be offset each year, equivalent to the emissions generated by burning more than 41 million gallons of gasoline in one year

    • Enough clean energy to power the equivalent of 71,739 homes annually

    • Project will increase patronage to local businesses and services through expanded workforce

    • AES cultivates local partnerships with organizations for economic and social impact

    • Low-cost supply of clean energy at a long-term fixed cost over the project lifetime

    • No permanent service requirements for the site, including the use of water and sewer

    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.
