Copia Power's Monarch Data Center would be a 4.6 million square foot, 1,000 megawatt campus on about 505 acres at 150 and 155 Penrose Lane in Mason Valley near Yerington, paired with a 500 megawatt natural gas backup plant and battery storage, and requiring an estimated 800 acre-feet of water a year. Lyon County commissioners approved the needed zoning change 3-1 on August 6, 2026, even as neighboring Reno, Nye County and Humboldt County have all passed data center moratoriums. Copia still needs final design approval and additional permits before construction, and Lyon County is separately developing a countywide data center ordinance.
Power bills in Lyon County
Most of the county is served by NV Energy.
2026 fuel cost filings is pending; NV Energy says it would take about $4 to $6 off a typical monthly bill. Nothing here changes a bill today. What matters is whether the large load contract survives intact; if it is weakened, the cost of plants built for data centers starts showing up in the next general rate cases around 2027 and 2028. Sierra Pacific 2024 general rate case (docket 24-02026) adds about $2.00 a month to a typical bill from October 2024.
NV Energy asked regulators to lower southern Nevada electric bills about 5.01 dollars a month from October 2026, citing falling fuel and wholesale power costs. In northern Nevada it asked to cut electric bills about 1.86 dollars a month while raising gas about a dollar.
