ADA-ES Awarded Contract for Mercury Control System

LITTLETON, Colo.--(Business Wire)--
ADA-ES, Inc. (NASDAQ: ADES) today announced that it has been awarded a contract
to supply an Activated Carbon Injection ("ACI") system for a new coal-fired
generating unit located in the Midwestern United States that will burn low
sulfur Powder River Basin ("PRB") coal. ADA-ES expects to deliver this system to
the new generating unit by the end of the second quarter of 2010, with startup
anticipated in the first quarter of 2011 once the new coal-fired generating
facility has been completed.

Dr. Michael Durham, President & CEO of ADA-ES, commented, "This contract is part
of a new generation facility currently under construction. The current markets
for our mercury control systems and powdered activated carbon sorbents are being
driven by regulations in 18 states, new power plants being constructed, and
regulations in several Canadian provinces. Once the ACI system is up and
running, it will require a continuous supply of activated carbon to control
mercury emissions, which will be procured under a separate contract."
