Created Equal
Much more than
a simple 3D CAD
rendering, digital
twins can signifi cantly
advance operational
performance.

A digital twin is a
computer simulation
of a physical
system or piece of
equipment that can
be used throughout
the life of a facility.
TO PROVIDE VALUE to the operating capability of
a power plant, a digital twin must include physics and
empirical-based modeling, product design information,
operational data, and failure-based mechanisms.
More than just a visual representation of an asset, a
digital twin can provide the actionable data necessary
to prevent failures, along with analysis and design
information needed for prognostic decision making.
Today, a digital twin is commonly defi ned as a

process. It's designed to detect, prevent, or predict the
overall state of a system or piece of equipment within
its lifecycle. While this broad defi nition may suffi ce at
a high level, it doesn't defi ne the specifi c characteristics
that make one digital twin more valuable than another.
In reality, a digital twin is a computer simulation of a
physical system or piece of equipment that can be used
throughout the life of the facility. As such, it should
