Fossil Plant Services

This is a challenging time to own and operate fossil-fired power plants. The majority of fossil units are over 25 years old, and many were originally designed for baseload duty: today, they're being run hard to meet new financial expectations, and that — combined with limited financial resources, reduced maintenance budgets, staff reductions, and fewer, shorter outages — makes managing these plants a difficult challenge. The industry faces other tough challenges as well: newer fossil units, operated at unprecedented high temperatures and pressures, raise major operation and maintenance issues inevitably associated with advanced designs and materials.

Structural Integrity Associates, Inc. (SI) is more than ready to help its clients meet the new challenges that face both older and newer fossil plants. SI has provided support and engineering services to the fossil power industry for more than 25 years, and has transformed that formidable experience and expertise into an integrated, multidisciplinary approach that combines engineering analysis, advanced nondestructive examination, materials evaluation, repair technologies, and data management to attain the best possible solutions for fossil plant owners and operators.
