The purpose of this Request for Proposal (RFP) is to solicit sealed proposals to establish a contract through competitive negotiation with the Joint Legislative Audit and Review Commission (JLARC) for the purchase of consulting and analytical services related to the impact of data centers on energy infrastructure, carbon emissions, costs, and customer rates in Virginia. JLARC staff intend to select one or more contractor(s) with expertise in (i) modelling utility-scale energy grid infrastructure and its associated costs and carbon emissions, and (ii) performing cost of service studies of energy utilities to identify potential rate subsidization. The selected contractor(s) will work with JLARC staff and the Weldon Cooper Center for Public Service (WCC), which is developing energy use and peak load forecasts.
