Having found experts in our community, we analyzed all the information AES had shared with residents about the project which brought us to the conclusion that the real financial value for their company was not from the solar panels or the energy they produced but from the massive lithium-ion array of batteries they claimed to need, which were far in excess of what was required to store the energy from the solar panels. AES’s real aim for this project was to pull power off the PNM grid when demand and rates were low and then sell it back at a higher price to us or other utilities that might choose to buy it at that moment.
As concerned citizens, we meet with County staff in July to explain this to them and ask if they were aware of what we’d discovered. It was clear this was news to them and, in fact, seemed to take them by surprise. We presume they then contacted AES to confirm our assertion because within a week or two of that meeting, the following happened: AES sent us an email saying they would no longer communicate with residents about the project, the AES representatives we’d been communicating with abruptly left AES, and then AES filed suit against the County claiming that the hazardous information about the lithium-ion batteries were now “trade secrets” that were not to be shared with the community.
October 6, 2023: The neighborhood group, Keep Eldorado Safe officially became the Clean Energy Coalition for Santa Fe County, a 501c(3) public charity and was now able to accept donations and hire an attorney.
January 2024: CEC made a motion to intervene in the “trade secrets” suit, which Judge Maria Sanchez-Gagne ultimately granted so we could try to force AES to be transparent and release the so-called Hazard Mitigation Analysis Report (HMA). Not wanting to answer the questions in our motion of discovery and thus create a public record, AES dropped their suit entirely and released the information in the HMA.
August 2024: After withdrawing their initial application, AES submits a new (revised) application with the County which includes a REDACTED Hazard Mitigation Analysis (HMA) report. They once again sue the County to prevent them from sharing the redacted information about the hazards of the batteries with the public, again claiming that they were Trade Secrets. After a one-day hearing/trial on the issue in District Court, Judge Matthew Francis found against AES which then again forced them to share the results of the controlled tests that were done on the NCA type batteries they intended to use on the project. The UNREDACTED report, which was never added to the AES application materials on the County’s website, shows the batteries AES planned to use failed 3 of 4 systems tests.
December 4, 2024: A public County hearing was held with the Sustainable Land Development Code (SLDC) Hearing Officer to determine if a conditional use permit (CUP) should be granted to the applicant (Rancho Viejo Limited Partnership, Rancho Viejo Solar LLC, and AES Clean Energy Development LLC) for the location zoned Rural Fringe. This would be the first of three quasi-judicial hearings with Santa Fe County on this matter.
December 23, 2024: SLDC Hearing Officer, Marilyn Hebert advised the County to deny AES’ application, stating: “The evidence indicates the Project would be detrimental to health, safety and general welfare of the area; the Project would create a potential hazard for fire, panic, or other danger; and the Project is inconsistent with the purposes of the property’s zoning classification and inconsistent with the spirit and intent of the SLDC and SGMP.”

February 3 and 4, 2025: The second public county hearing was held over two days with the County Planning Commission voting 6 to 1 in favor of the project. The opposed parties with standing were given a total of 2 hours 47 minutes to present with no meaningful cross-examination allowed, while the parties in support of the project accumulated a total of 6 hours 27 minutes.

August 11 and 12, 2025: A FINAL COUNTY HEARING took place for the full Board of County Commissioners to consider the Rancho Viejo Solar (& Battery) Project. Multiple parties with standing presented for and against the project including CEC. Public comments in person were given on August 12, with 112 opposed and 40 in support; total comments in person and emails were 418 opposed, 280 in support. The County extended the hearing for a third day on August 13 to hear more from AES and the County staff, holding their decision for a later date.
August 26, 2025: Despite the clear objections on the part of the public and the Hearing Officers recommendations, the Board of County Commissioners (BCC) votes 4 to 1 in favor of approving the Conditional Use Permit (CUP) for the Rancho Viejo Solar Project (RVSP). Commissioner Lisa Cacari Stone was the single dissenting vote. Her findings are provided at the bottom of the County’s Final Order with Conditions. The CEC Team meets to discuss appealing to District Court. The County’s final order:

September 9, 2025: A new application from a Spanish-based company, Linea Energy LLC, for a 2-phased solar and battery storage project called Globemallow 1 and 2, that had been in the works was now officially submitted to the county. The project site is located in the southern part of Santa Fe County, 2.4 miles north of Stanley and about 30 miles south of Eldorado and the city of Santa Fe. CEC begins reviewing Linea’s application.
