Utilities face massive changes

The landscape changes almost daily

Diverse energy sources impact
traditional operations

Utility organizations must rethink
business models

Safety, reliability, and grid resilience
must be maintained

Going digital can transform
your business

The pace of change varies
regionally, but PROGRESS
CONTINUES WORLDWIDE

DISRUPTION in the Utility Industry

Bentley’s mission is to provide INNOVATIVE SOFTWARE AND SERVICES for the enterprises and professionals
who DESIGN, BUILD, AND OPERATE the world’s infrastructure –
sustaining the global economy and environment for IMPROVED QUALITY OF LIFE.

EXECUTIVE SUMMARY
“…Even though load and DER reside “behind-
the-meter” the modeling for each of these
respective network elements requires a
different set of data.
As the penetration level of DER increases, the
classical transmission model of distribution
system load (netted generation and load) is
not valid; the unique characteristics of DER
must be modeled separately….”
