     to energy market signals for seamless demand response participation

Business Wire

BALTIMORE -- December 10, 2012

Constellation, a business unit of Exelon, today announced the nationwide
launch of VirtuWatt™ Link, the first web service application to facilitate
automated load response program participation. VirtuWatt™ Link allows a
facility’s existing automation system to manage load curtailment automatically
based upon energy market signals and pre-set scenarios -- without the
installation of redundant or proprietary building controls hardware.

By reducing the upfront cost associated with load response automation,
VirtuWatt™ Link enables a broader range of facility types and sizes to
participate in a wider array of energy market programs. VirtuWatt™ Link is an
extension of Constellation’s VirtuWatt™ energy management platform, which
allows commercial and industrial customers to easily monitor energy usage in
real time and schedule load curtailments for load response programs.

“VirtuWatt™ Link provides a leap forward for our customers and building
automation vendors in making facilities behave intelligently, by efficiently
connecting existing automation infrastructure to energy market signals,” said
Gary Fromer, senior vice president, load response for Constellation. “This
nexus of market access, intelligence and surgical action enables commercial,
industrial and institutional power users to be proactive and strategic about
how and when electricity is used, without compromising business operations or
requiring wholesale replacement of existing controls infrastructure.”

Companies that offer a wide variety of energy management and automation
solutions, from customer-specific to broad-in-scope, are teaming with
Constellation to implement VirtuWatt™ Link as a pre-integrated, value-add
option.

During the beta release of the solution, Trane, a leading provider of energy
efficiency HVAC systems, building and contracting services, parts support and
advanced control, created a VirtuWatt™ Link adapter for its Tracer™ and TIS
platforms, which is now live and supporting load response programs at Trane’s
Texas facilities.

Vedero Software, a software provider of automated demand response services for
office complexes, schools, hospitals and datacenters, has integrated the
VirtuWatt™ Link product with its cloud-based energy and load management
platform.

“VirtuWatt™ has enabled us to deliver a reliable, seamless, end-to-end
solution for our customers, while reducing complexity and costs associated
with demand response signals,” said Joe Pollard, CEO of Vedero Software.
“Constellation is certainly demonstrating leadership by allowing both channel
partners and customers to benefit from a lower cost of implementation and
better access to energy markets.”

VirtuWatt™ Link provides comprehensive load response and security services,
including: authentication access control, ISO event dispatch notification and
acknowledgement and utility meter usage data. VirtuWatt™ Link can be
integrated to any energy management or controls system that utilizes web
services. Its architecture is designed to seamlessly handle demand response
market signals and energy data from utilities and independent system operators
(ISOs), and is built to accommodate developing demand response protocol
standards, such as OpenADR 2.0.

On December 13, 2012, at 2 p.m. EST, Constellation’s VirtuWatt™ and VirtuWatt™
Link will be the focus of an energy management webinar hosted by Environmental
Leader. Click here for registration details.
