FOR IMMEDIATE RELEASE

ADA-ES SELECTS ENGINEERING, PROCUREMENT & CONSTRUCTION CONTRACTOR FOR ACTIVATED CARBON PRODUCTION FACILITY

LITTLETON, CO – November 28, 2007 – ADA-ES, Inc. (NASDAQ:ADES) announced today that it has selected BE&K Construction Company of Birmingham, Alabama to provide the engineering, procurement, and construction (EPC) work required to build ADA-ES’ first Activated Carbon (AC) production facility.

The initial tasks for which BE&K has been contracted involve a detailed review of the project’s extensive engineering and procurement activities accomplished to date, and preparation of the detailed final plans for the remainder of the EPC activities of the project. The Company expects to enter into additional contracts with BE&K for services subsequent to those being provided under this preliminary agreement.

This selection of BE&K marks a key milestone in ADA-ES’ project schedule for the development of a large-scale AC production facility, which, if completed, will be the largest AC plant built to date. The plant is being designed to maximize efficiency and produce the most cost-effective AC product for the mercury control market. ADA-ES has filed for permits to build AC plants in North Dakota and Louisiana. Permit time lines and overall business environment will dictate which site ADA-ES will choose to build first. Commercial operation of the first plant is planned for the first quarter of 2010. Credit Suisse is serving as advisor to ADA-ES on the financing necessary to build the plant.

Dr. Michael Durham, President and CEO of ADA-ES, commented, “We are very pleased to have secured a company with the depth of expertise, experience, and talent that the BE&K team brings to this project. The EPC role is critical to completing the project on schedule and on budget, and BE&K has proven these abilities on multiple projects of this scale and larger.”
