Marriott Selects Constellation Energy to Provide Load Response, Automated Curtailment and Energy Management Capabilities
Program Will Improve Energy Efficiency and Savings in More Than 250
Marriott Properties Across the United States
Constellation Energy (NYSE: CEG) and Marriott International, Inc. (NYSE:
MAR) today announced
an agreement to develop over 23 megawatts of load response
capability across more than 250 Marriott-managed hotel properties in the
mid-Atlantic, New England, New York, Texas and California. Load response
is the reduction of electrical consumption in response to high wholesale
electricity prices, system resource capacity needs or system reliability
response program is designed to improve energy efficiency and reduce
electricity costs at Marriott properties, while ensuring guest comfort
through expanded building automation capability and customized load
"Marriott International sees this program as a direct link to our global sustainability
efforts," said Robert Bahl, vice president of engineering and facilities
for Marriott International, Americas. "In addition to load response, the
associated automation of this program will help to dramatically improve
the energy efficiency of our hotels, saving an estimated 1.2 million
kilowatt-hours of electricity annually."
As part of the agreement, Marriott will leverage Constellation Energy's
VirtuWattTM energy management system in concert with existing
building automation to track electricity usage, bid directly into demand
response markets and automate load curtailment strategies. Marriott
properties may elect to receive financing through Constellation Energy's
load response program to defray the upfront cost of demand response
related equipment upgrades, as well as take advantage of load-based
utility incentives in markets where available.
"Constellation Energy worked with us and our partners for more than a
year to develop a load response program and a customized technology
solution platform to complement our specific business objectives and
diverse portfolio of hotels," said Douglas Rath, energy director for
Marriott International, Americas. "By leveraging Marriott's existing
building controls systems, vendor relationships, utility and
Constellation Energy incentive opportunities, we are able to expand our
automation capabilities, increase facility efficiency, drive
participation in load response programs and accelerate Marriott's
In 2010, Constellation Energy and Marriott conducted a load response
analysis and pilot at 17 Marriott properties, which identified
technology requirements and laid the groundwork for this national scope
load response program.
"Constellation Energy is a longtime partner with Marriott on energy
procurement, and together we've created a load response program that is
a coherent driver within Marriott's overall energy management strategy,"
said Gary Fromer, senior vice president, demand response, for
Constellation Energy. "Providing properties access to real-time usage
data and responsive automation capability will allow Marriott to
maximize energy market revenue and savings opportunities, and in a
challenging economic climate, do so with the most efficient use of
Through a partnership with Automated Logic Corporation (ALC),
Constellation Energy will implement indirect load control at Marriott
properties where ALC systems are installed. Constellation Energy's
VirtuWatt platform will enable Marriott properties with other brands of
automation to implement pre-set curtailment scenarios for building
systems such as generation, pumping and HVAC, based on load shortages,
electricity usage or real-time pricing. A groundbreaking interface
provides facility operators an intuitive web-based interface for
selecting specific curtailment scenarios on an as needed basis to match
daily business demands. VirtuWatt also provides Marriott International
with a centralized system for load control at multiple sites, an
enterprise-view of electricity usage and data grouped by independent
system operator or regional transmission organizations.
