Power Quality & Reliability

At CenterPoint Energy we understand that our customers demand both reliable and high-quality electric service. Dependable electricity is a necessity for the productivity and comfort of our residential customers.

We make reliable power delivery a top priority. In these pages, we explain reliability and power quality and events that produce them. We’ll also explain how the electric delivery system works and what to expect from your CenterPoint Energy delivery service in terms of reliability and power quality. We will also identify possible solutions to help relieve undesired events.

What do power quality and reliability mean?

Power quality is measured by fluctuations in electricity, such as momentary interruptions, voltage sags or swells, flickering lights, transients, harmonic distortion and electrical noise (i.e., fewer such incidents indicate greater power quality)
Reliability is the continuity of electric delivery measured by the number and duration of power outages (i.e. fewer, shorter outages mean greater reliability).
