Residents of Sangamon County, Illinois, are voicing strong opposition to a proposed CyrusOne data center, which is anticipated to receive approval from the Sangamon County Board on March 23. Concerned citizens, including a letter writer whose family has lived in the area for over 150 years, highlight environmental impacts such as increased energy consumption, noise and air pollution from diesel generators, and the destruction of prime farmland. They also question the lack of commitment from CyrusOne regarding expensive firefighting equipment and a plan for decommissioning the 280-acre facility. Opponents argue that the county board, with the exception of member Marc Ayers, is not adequately addressing these concerns or demanding sufficient protections for the community and ratepayers. A former technical sales professional with extensive experience in data-driven environments acknowledges the economic benefits but warns of long-term electrical and economic impacts, including potential utility cost increases for Ameren and co-op customers. He advocates for transparency in power-supply agreements and ratepayer safeguards. Calls have been made for the Sangamon County Board to approve a moratorium on data center development to allow time for proposed state legislation in Illinois to establish guardrails and protections for counties hosting such facilities. Residents also cite negative experiences with a CyrusOne data center in Aurora, where neighbors reportedly experience constant noise and vibrations, and express skepticism about the promised local jobs, noting that many data centers are pre-fabricated.
