Coal Asset Valuation Tool (CAVT)

Jump to the download form

Synapse’s Coal Asset Valuation Tool (CAVT) is a spreadsheet-based database and model that analyzes the future economic viability of coal units. Now on version 6.0, CAVT estimates the costs for individual coal units to comply with environmental regulations and compares these costs to electricity market prices. It aggregates publicly available data (such as capacity, generated power, and heat rate) on non-cogenerating coal units and combines this with publicly available cost methodologies to calculate the cost of complying with environmental regulations. The calculated future cost of each coal unit is compared to the estimated future cost of wholesale market purchases to determine future economic viability on a unit-by-unit basis.

Even without environmental controls, many existing coal plants are currently uneconomic when compared to other market purchases. Once the costs of these controls are taken into account, the economics of these plants worsen. Figure 1 compares the future economics of coal units that are slated for retirement and coal units that are currently not announced to retire. While this figure does account for operating and capital costs of likely environmental retrofits such as scrubbers, baghouses, cooling towers, effluent limitations, and ash remediation, this figure does not include costs associated with carbon dioxide, such as the type that might be imposed by the Clean Power Plan. Even without these additional carbon costs, few coal plants are economic compared to market purchases on a forward-going basis.

Note: Each “x” and “o” represents a single coal unit, operating at an average historical capacity factor. If units are in the blue area, they are economic compared to current market conditions. If units are in the orange area, they are non-economic, and should be retired. Units in the grey area may or may not be economic.
