Electricity is essential for companies to conduct business as usual. That's why CenterPoint Energy strives to maintain a safe and reliable electric delivery system.

We understand that our customers demand reliable, high-quality electric service. Dependable electricity is a necessity for the productivity of our business customers.

We make reliable power delivery a top priority. On these pages, we explain power quality and reliability 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 power quality and reliability. We will also identify possible solutions to help relieve undesired events.

What does 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).
