Challenge

A utility client will be bringing various plant units offline. The units will be decommissioned and retired. The plant is a coal-based power plant with an air quality control system (AQCS) consisting of a selective catalytic reactor (SCR) and wet flue gas desulfurization system (FGD) to control emissions. The units have a total net generating capacity of 1,135 MW with the oldest unit having been in service since 1959.

Solution

Valdes Architecture & Engineering (Valdes) developed the initial scope of the project and obtained capital project budget approval. The site is also home to a generating station and site bulk material handling facility. Valdes has identified and is executing projects to modify all interdependent systems that are required to ensure the uninterrupted operation of the remaining assets. Valdes has assembled a project team consisting of plant personnel, corporate personnel, and third-party vendors to support the decommissioning effort. The project team has developed a plan to bring the units to a safe and stable long-term shutdown condition in preparation for the future demolition of the site. The plan also considers all environmental, financial, and legal requirements associated with taking the units out of service. Valdes is developing and controlling the budget and schedule for the project as well as providing engineering support as required.

Impact

Valdes is actively developing managing and monitoring budgets, schedules, and work packages to ensure all the client objectives are satisfied. Valdes is the sole point of contact and accountability for all aspects of the decommissioning.
