Bentley Releases Comprehensive Engineering Design Solution to Advance GIS for Electric Utilities

Bentley Systems, Incorporated today released its comprehensive
engineering design solution to advance GIS for electric utilities.

The solution includes Bentley Electric XM and Bentley Expert
Designer XM - two new fully interoperable products built on Bentley's
next-generation geospatial technology. In addition, Bentley Electric
XM is delivered with a robust industry best practices data model for
electric utilities, along with an intuitive visual modeling editor
that can be used to modify and extend the model.

Bentley's solution for electric utilities supports new levels of
efficiency in managing electric distribution networks throughout the
plan, design, build and operate lifecycle. Enabled with configurable
business workflows, the solution helps integrate mapping, facilities
management, and design with work management and asset management
workflows. Users can optimize designs, specify all materials and labor
required to complete work requests, and have flexibility in managing
labor and materials costs, all in the context of defined business
processes.

Said Carey Mann, vice president Geospatial Solutions, for Bentley,
"By removing the inefficiencies of disparate systems from tightly
coupled business processes, Bentley's new solution represents a new
paradigm for electric utilities. For the first time, facilities
mapping, design engineering, and analytically driven estimating have
been integrated into a single work environment."

Bentley Electric XM delivers core mapping, network documentation,
facility mapping, and facility management functions. In addition, it
provides feature placement, editing, and viewing, supports directional
network trace and highlight, validates feature placement against
configurable business rules, and enables simple service delivery.

Bentley Expert Designer XM extends Bentley Electric XM to add
intelligent and optimized design and integrated estimating. It
features rapid rules-based placement of facilities, provides an
interactive catalog with drag and drop placement, automatically
assigns compatible units (standard materials and labor), and
facilitates design version and cost comparisons.

Whether graphically editing or dragging catalog items to work
points, the estimate is dynamically created as each feature is placed,
edited, or removed. Connectivity and structural attachments are
maintained, while structural and electrical analytical capabilities
support optimal pole, transformer, wire, and fuse sizing.

The Bentley Electric XM data model is extensive and supports:

-- Poles, framing standards, switch cabinets, conduits, vaults
and duct banks, and guys

-- Conducting features in the primary and secondary network

-- Maintenance inspections

-- Structural analysis

-- Guying, pole loading, sag and clearance, and cable pulling

-- Primary distribution network

-- Conductor

-- Transformers, sectionalizers, and other devices

-- Electrical analysis

-- Local flow, motor starting, and voltage flicker

-- Equipment sizing and optimization

-- Secondary distribution network

-- Street lighting

-- Service and loads

-- Load modeling and secondary wire sizing

Bentley Electric XM and Bentley Expert Designer XM are part of the
increasingly comprehensive solution offered by Bentley to operators of
electric utilities. With products to design, build, and operate power
generation plants, substations, and transmission and distribution
networks, Bentley provides a true plant-to-consumer solution.

Bentley's unique federated data management technology ensures that
engineering and business documents are integrated with information
stored in spatial databases such as Oracle 10g. It accomplishes this
all in the context of definable workflows that support established
business processes and enable collaboration among distributed
participants.
