Closure of Supercritical Coal Power Plant

Project Approach

One of DECARB’s subject matter experts managed the closure a three-unit, 1,650 MW supercritical coal power plant in PJM.

Closure activities encompassed plant operations, commercial operations in the PJM market, deactivation planning and execution, shuttered plant O&M and environmental requirements, demolition analysis, and site preparation for a 1,000 MW natural gas-fueled combined cycle development project to be constructed on the existing coal pile.

Details included:

Plant shut down scope and timing planning

• Pre-and-post staffing plans
• Regulatory and RTO notifications
• End-state of closure: cold and dark, permanent closure, demolition
• Sequencing: shut down of operations, environmental containment, security, power requirements
• Monetization opportunities: inventory, equipment, coal stockpile
• Setting environmental remediation requirements: asbestos, PCBs, soil contamination, coal pile

Closure plan execution

• Competitive procurement of remediation functions for Decontamination and Demolition
• Evacuation of materials from all tanks, silos, mills, etc.
• Removal and disposal of all hazardous wastes – chemicals, solvents, asbestos, mercury, POLs, etc.
• Removal of underground storage tanks
• Ash landfill closure

Site repurposing preparation

• Negotiation of land option/purchase agreement with developer
• Management of interconnection agreement process
• Negotiation of natural gas, water, and EPC contracts
• Obtained all required air and water discharge permits
• Combined cycle plant was developed into a shovel-ready state
