The PUE Challenge

Whether operating an on-premises data center or a colocation facility, the challenge is similar: computing infrastructure consumes large amounts of electricity, making energy a major operating expense and an important factor in overall efficiency. Reducing unnecessary consumption is therefore a key priority.

Facility managers aim to ensure that as much energy as possible is used by the IT equipment itself. Higher consumption from supporting systems—particularly cooling—can increase PUE and may indicate opportunities to improve facility design and operational efficiency.

Improve your PUE

Data center power efficiency is commonly measured using Power Usage Effectiveness (PUE):

PUE = Total facility energy ÷ IT equipment energy

The closer the PUE value is to 1.0, the greater the proportion of facility energy used directly by IT equipment. A higher PUE indicates greater consumption by supporting systems, such as cooling, and may highlight opportunities to improve energy efficiency.

SATEC combines high-accuracy metering equipment, including multichannel meters, with the Expertpower energy management software suite. Together, these solutions support real-time energy monitoring, detection of irregular consumption, and evaluation of overall system efficiency. Revenue-grade meters may also support tenant or customer billing in colocation and managed hosting facilities.

SATEC also provides solutions for direct DC metering. As some data centers adopt DC distribution systems, accurate monitoring is essential for evaluating performance and managing energy consumption.

SATEC’s DC metering portfolio includes compatible Hall-effect sensors, power supplies, and solutions for measuring higher DC voltage ranges, including applications up to 3,000 V DC.
