Dominion Virginia Power and Clean Power Plan Costs: A brief review of the Dominion's 2015 Integrated Resource Plan compliance cost estimates

The Dominion Virginia Power filing with the State Corporation Commission does not really provide a full integrated resource plan (IRP). Rather, Dominion argues tha tthe uncertainty over federal greenhouse gas regulation is too great to allow the company to do an integrated plan.  The document presents cost estimates for some stylized scenarios that comply with the proposed federal regulations, known as the Clean Power Plan (CPP). The CPP establishes emisison rate standards for greenhouse gas emissions from existing power platns. The IRP incorrectly attributes to the CPP costs that would occur with or without the CPP.  This and other modeling choices result in substantially overstated estimates of compliance costs.
