Turnkey services, real-time monitoring

The Signature service gives you direct access to Hydro‑Québec professionals who will help you optimize your electrical installation through proactive and preventive measures.

The Signature service analyzes and diagnoses power quality. It includes the installation of measurement tools designed for real-time data capture. This data is then analyzed and the results put toward helping you avoid recurring production losses.

What’s more, you’ll automatically be notified in real time by e-mail or cell phone of any load loss in addition to receiving weekly reports by e-mail.
