Power Generation

Power generation facilities must comply with evolving air emissions monitoring regulations. These include the Environmental Protection Agency’s 40 CFR Part 75, Part 60, and Part 63 requirements, as well as state and local air mandates. In addition, they face demands for costs savings and efficiency, often with a shrinking staff. ESC Spectrum’s Continuous Emissions Monitoring System (CEMS) solutions, including industry-leading Data Acquisition Systems (DAS) plus a wide variety of DAS and CEM systems, hardware, and services, are tailor-made to help power generation plants meet their challenges.
