Edged is building a 187 million dollar, 13.2 megawatt data center on Ankeny's southeast side, near Southeast Four Mile Road just north of Interstate 80. The Ankeny City Council approved a development agreement with a tax increment financing incentive capped at 2 million dollars, and construction broke ground on May 6, 2025, with completion expected in 2027. The company says the facility will use closed loop, waterless cooling.

Meta's Altoona campus is the company's largest data center in the world, spanning more than 5 million square feet after a seventh expansion completed around 2025 pushed total investment above 2.5 billion dollars. The site has been running since construction began in 2013 and is powered in part by wind energy contracts with MidAmerican Energy. It already employs more than 400 people and drew roughly 1,000 construction workers at its peak.
Most of the county is served by MidAmerican Energy.
MidAmerican Energy is asking the commission for a 5.2% residential increase (MidAmerican Energy natural gas rate increase (docket RPU-2026-0001)). On a $58 monthly bill that is about $3 to $5 a month. This case does not set rates directly, but the new solar plant it approves will eventually be paid for through customer rates, and MidAmerican has said data center growth is a major reason it is needed.
MidAmerican Energy's proposal would raise a typical residential customer's monthly natural gas bill by about 2.89 dollars, roughly 5 percent, and a temporary interim rate increase subject to refund has been in effect since around July 17, 2026. The Iowa Utilities Commission held public consumer comment meetings on September 8 in Cedar Rapids, September 9 in Des Moines and virtually, and September 10 in Sioux City, all in 2026, where MidAmerican reiterated its request; no settlement or decision date has been reported, and the company's prior gas rate case took roughly nine months from filing to a final order.
