FERC Notice of Proposed Rulemaking onTransmission Planning and Cost Allocation Dani Bennett Progress Energy 3
Purpose of the NOPR • FERC proposes to require the regions to develop transmission plans and cost allocation methods that consider the benefits of new transmission facilities, including reliability, economics, and complying with state or federal laws or regulations (e.g. public policy). • FERC also proposes to require each pair of neighboring regions to coordinate transmission planning and cost allocation. 4
Cost Allocation • Each region to propose its own cost allocation method • FERC would not require a one size fits all method for allocating costs of transmission facilities • Development of cost allocation proposals must start at the regional level • If region can’t decide on a cost allocation method, then FERC would decide based on the record 5
Cost Allocation Principles • Regions would develop cost allocation methods based on the following principles: • Costs allocated “roughly commensurate” with estimated benefits • No involuntary allocation of costs to those receiving no benefit • Benefit-to-cost thresholds must not be excessive • No allocation of costs to other regions except pursuant to agreements • Cost allocation methods and identification of beneficiaries must be transparent • Different allocation methods could apply to different types of transmission facilities 6
Benefits Regions would be required to consider benefits including reliability, economics, and enabling compliance with existing laws or regulations that may drive transmission needs. The proposal would not prevent regions from considering other public policy objectives. If a state has a law establishing a renewable electricity standard, then a region must consider transmission needs driven by that law. 7
Who Gets to Build • Removal of federal rights of first refusal from FERC jurisdictional tariffs and agreements; but no preemption of states • Encourage competition and new entrants 8
Merchants • Merchant transmission developers may continue to negotiate cost recovery from specific customers • Must comply with all relevant reliability requirements 9
Coordination Between Regions • Evaluate benefits of transmission lines that begin in one region and end in a second region. • Identify method(s) for allocating the cost of lines that the regions decide are mutually beneficial. 10
Timeline • Comments are due on September 29, 2010 • Regional compliance filings are due 6 months after final rule promulgated • Interregional transmission planning agreements and interregional cost allocation compliance filings are due 12 months after final rule promulgated 11
