AES’ Rancho Viejo Solar project is a planned solar facility that will incorporate the most advanced solar energy and battery storage technologies and is designed to minimize impact on the local environment. Rancho Viejo Solar will support New Mexico’s clean energy goal of 50% renewable by 2030, and 100% renewable by 2045.
96 MW Solar + 48 MW Battery Energy Storage
Enough clean energy to power 30,000 New Mexican homes annually
* EPA Calculator
Developed on 680 acres of privately owned land
Located off South NM HWY 14
Provides clean energy to PNM customers
35-year project life span with AES as long-term owner and operator
For publicly available copies of the CUP application, please contact the Santa Fe County Planning Department.
AES submitted Rancho Viejo Solar's Conditional Use Permit to the Santa Fe Planning Department on Jan 26, 2023. Copies will become public information upon the determination of a complete report by County officials.
The AES team has been working closely with the community over the past many months and we have heard your questions, concerns, and suggestions. We have listened and adjusted our plans to ensure that AES’ Rancho Viejo Solar project reflects our commitment to being a good neighbor, and delivers long-lasting, positive impact.
The site design has been adjusted so that the project is no longer directly to the north of the San Marcos neighborhood and therefore all necessary modules will move to the northeast corner of the site. This shift in design will continue to ensure the neighboring residents of Rancho San Marcos will have as unobstructed viewshed as possible to the north. Updated visual simulations were developed and are available below on this page. The battery energy storage systems (BESS) will be located in the remote northeast corner of the site design, more than one mile from any residential property.
Neighborhood Meetings: To apply for a Conditional Use Permit, the County requires project applicants to host a pre-application neighborhood meeting. AES hosted two in-person and one virtual meeting, giving notice to adjacent property owners by First Class Mail, email notification, and published a half-page advertisement in the Santa Fe New Mexican, inviting the public to attend. Neighborhood meetings were held at the Turquoise Trail Charter School on August 3 and October 4, 2022. A virtual meeting was hosted on January 4, 2023. A recording of the 10/4/2022 meeting is linked at the bottom of the page, along with the slide presentation.
Long-term tax revenue to counties, towns and school districts
Job creation during construction and operation
Landowner income diversification, empowering landowner rights
Local economic stimulus during construction

Best practices in responsible battery energy storage management
At AES, safety is our highest priority, and we’ve focused on improving lives for more than 40 years. As a leading innovator in energy solutions, sustainability is core to both our strategy and our culture. We are committed to responsible land use and incorporating sustainable best practices into the entire project lifecycle, contributing to building a domestic circular renewables economy and reducing foreign dependence.
AES is the world leader in lithium-ion-based energy storage, both through our projects business and joint venture Fluence. We pioneered the technology over one decade ago, and today almost half our new projects include a storage component.
AES is working closely with Santa Fe officials during the Rancho Viejo Solar project’s development and with the Santa Fe County Fire Department to implement safety best practices and training.
AES designs, specifies, and procures energy storage modules, systems, and enclosures driven by wholistic plant safety, performance, and reliability metrics. The components are independently tested and then certified to several industry standards, including UL 1642, UL 1973, and UL 9540, as well as designed compliant to NFPA 855.
We conduct a series of studies that ensure our projects are thoughtfully and responsibly designed.

Partnering with communities for the future of energy
At AES, we understand that our success as a company is only as strong as our partnerships with the communities where we operate. That’s why we partner with communities, customers, state agencies, higher education, elected officials, and other key stakeholders to see how we can best work together to support sustainable social and economic development.
Building New Mexico's clean energy workforce with Santa Fe YouthWorks
AES has partnered with Sante Fe-based nonprofit, YouthWorks, and donated funds that will allow 10 students to attend solar installation training courses to prepare them for the PV Associates exam and a career in the renewable energy industry. Since 2001, YouthWorks has served thousands of youth while expanding youth development opportunities that include youth advocacy, high-impact interventions, alternative education, and employment connections for young people.
Training students for a future in solar with Solar Energy International
AES has partnered with Solar Energy International (SEI), a nationally leading solar training and educational non-profit, to provide solar workforce development training in New Mexico. As part of that effort, AES has created an AES-funded scholarship, which provides financial assistance to 15 New Mexico residents to cover solar education tuition fees.
The partnership with SEI also includes services for colleges and universities to provide career development consulting for the future solar industry workforce. These efforts aim to stimulate participation in New Mexico’s clean energy future.
AES has partnered with schools in New Mexico to provide access to renewable energy educational materials that will continue to resource teachers and create learning opportunities for our clean energy leaders of the future.
