Advanced Control Systems and ESRI Partner For Integrated Utility Smart Grid Solutions

TAMPA, Fla., Jan. 22, 2008 (PRIME NEWSWIRE) -- Advanced Control Systems, Inc.
(ACS), a leading provider of smart grid automation and system solutions to
global utilities, and ESRI, the world's leading developer of geographic
information systems software, announced jointly today here at DistribuTECH that
ACS has joined the ESRI partner program.

The companies will work together to expand the available integration between
their products in support of emerging smart grid market requirements for
increasingly tighter integration between geospatial and real-time smart grid
systems.

"With the entire electric utility industry focusing on smart grid solutions now,
we welcome our partnership with Advanced Control Systems and look forward to
delivering real value to our mutual customers through the relationship," said
Bill Meehan, PE, director of utility solutions for ESRI.

ACS plans call for improved integration that supports incremental model changes
to ACS system network topology directly from the ESRI geodatabase. Utility
companies will then have tools to automatically synchronize, without the need
for cumbersome intermediate files and processes, changes between geographic data
in ESRI applications and the real-time database and network feeder models that
support ACS smart grid systems including feeder automation, substation
automation, and distribution management system applications.

"We look forward to our partnership with ESRI so we can tightly integrate smart
grid solutions with GIS and deliver added value to current and prospective
customers alike," said Jeff Smith, director of marketing and alliances ACS.
