Can Data Centers Achieve 99.999-Percent Reliability
In a world of long lead times and rising expectations, using proven tools brings you one step closer to the reliability your customers now expect.
Speed to power. “Five nines” of reliability. “We need more grid capacity.” These are the phrases you hear every day from data center developers and hyperscalers. Their focus falls on getting the building designed, permitted, built, powered, and running. Every month of delay can cost a large data center tens of millions in lost revenue, so the pressure to energize quickly is intense.
What often drops out of that conversation is a simple question: Once the site is online, how do you keep it that way for the full design life? In an era of strained supply chains, “run to failure” is no longer a safe strategy for critical equipment. During COVID-19, global manufacturing and logistics disruptions hit many core grid components, and six years later availability still has not fully recovered.
Transformers sit near the top of that risk list. Large power transformers that once took roughly a year and a half to procure can now require as long as seven years from order to delivery. Medium- and low-voltage units have followed the same trend, with lead times stretching from under a year to multiple years. When a key transformer fails, you may not be able to replace it within the current planning horizon. That reality changes the economics of reliability.
Fortunately, you have practical tools to extend transformer life and reduce unexpected outages. The most important is dissolved gas analysis (DGA), which measures specific gases in transformer oil to reveal emerging problems. Think of DGA as a routine blood test for your transformer fleet. Just as a doctor watches changes in cholesterol or enzyme levels over time, operators can track gas trends to spot overheating, arcing, or insulation breakdown before they lead to failure.
Utilities have relied on DGA for decades as a cornerstone of transformer health monitoring, combining online sensors, periodic laboratory testing, and clear maintenance actions. For data center operators, adopting these established utility practices is part of becoming a good grid citizen, protecting your own uptime while supporting overall system reliability.
In a world of long lead times and rising expectations, using proven tools like DGA brings you one step closer to the reliability your customers now expect.
