SACRAMENTO, Calif.and ST. JOHNSBURY, Vt., Dec.19, 2013 /PRNewswire/
--GridSense Inc., an Acorn Energy company (NASDAQ:ACFN), announced today the
completion of the sale of its BushingIQ^® product line to WEIDMANN Diagnostic
Solutions Inc. (a subsidiary of WICOR Holding AG).

BushingIQ^® measures a transformer's bushing insulation power factor
continuously, under load and in all weather conditions directly on the
bushing. It also provides accurate and early indication of incipient bushing
failure. It not only determines internal insulation integrity, but also
identifies external issues that can affect performance, such as
pollution-related surface contamination.

"The BushingIQ^® product line is an excellent fit for WEIDMANN'S growing
portfolio of power transformer monitoring systems. Bushings are a major cause
of catastrophic transformer failure and should be a part of an overall
monitoring strategy for large power and sub-station class assets. We believe
the BushingIQ^® technology is the best available in the industry and we look
forward to continued success with the product line," said Jeff Goolgasian,
President of WEIDMANN Diagnostic Solutions Inc..

"Divesting BushingIQ^® allows GridSense to streamline its manufacturing
operations and concentrate on our core suite of products aimed primarily at
the distribution transformer segment. This transaction is a true benefit for
both organizations," stated Joe Musanti, President of GridSense.

WEIDMANN will directly produce the product under the InsuLogix® B brand name
and assumes all warranty, customer and technical support activities for
installed units.
