Decommissioning Services

With the current pressure on utilities to reduce costs, improve emissions, upgrade & diversify their fleets, and still increase shareholder value, there has been increased demands to shut down or idle large coal-fired power plants.  Doing so takes planning and smart execution to ensure success.  Enthalpy Energy Services can provide a complete turn-key solution from start to finish to our clients that includes:

•Project Management

•Decommissioning Planning and Design including navigating permit requirements, performing environmental surveys/studies, performing asset recovery studies, developing specifications, and performing engineering work

•Scope Development, Cost Estimating, and Scheduling

•Bid Evaluations for Demolition Contractors

•Construction Management including Safety and QA/QC Management

•Operations Staff Augmentation including plant operators and maintenance crews to supplement waning utility staff, clearance administration personnel, technicians and field engineers, etc.

EES’s goal is to guide our clients through the entire process from initially establishing a conceptual path forward, to performing all the pre-demolition planning, to overseeing and managing the actual decommission and demolition process. We want to make this process easy for our clients.

Decommissioning Procedure Development - Electrical and Mechanical Systems

Arizona Utility - Conventional Coal-Fired Generating Station Units 1,2,3

August 2017 - December 2019

 

Arizona Utility and owners of Station shut down the 2150 MW coal fired station located in Northern Arizona at the end of 2019.  Enthalpy Energy Services (EES) developed the decommissioning procedure packages; once executed, systems will be dead and safe for the demolition contractor to perform their work.  In general, the procedures confirm and expand on existing LOTO (tagging clearance procedures) indicating step by step procedures to shut down the plant with proper air gapping (isolation) to meet OSHA standards during the final Units outage.  The procedure packages developed reference existing drawings and include marked up drawings. The decommissioning procedures will be used with a dual purpose: to provide request for proposal (RFP) packages to qualified contractors and as a final care and custody transfer from Station to the demolition contractor performing the de-commissioning.

Coal-Fired Power Plant - Outside Areas Operational Support

Colorado Utility – Conventional Coal-Fired Generating Station

December 2019 - Present

 

As Unit 1 of Station is approaching shutdown in 2025 and Units 2 and 3 shortly thereafter, the plant is losing operations staff to other longer-term opportunities. Utility hired EES to provide Operational support as needs arise. Enthalpy-ES is currently providing support to the Water Treatment Systems, the Scrubber System, and the Coal Handling Areas, with an expectation for this service to expand to all outside areas.
