FERC Order 1000 

The Federal Energy Regulatory Commission’s (FERC) new rule mandates how public utility transmission providers plan for and allocate the costs of new projects on a regional and interregional basis.  Order 1000 builds upon Order 890, which required transmission planning based on open, transparent and coordinated processes.

Key Planning Requirements

Order 1000 seeks to ensure more efficient and cost-effective regional planning and interregional coordination, a major step forward in advancing transmission planning. The order requires that:

  • Public utility transmission providers participate in a regional transmission planning process to produce regional plans.
  • Local and regional transmission planning processes consider state and federal public policy requirements.
  • Public utility transmission providers coordinate with neighboring regions to determine whether more efficient or cost‐effective solutions are available for their transmission needs.

Key Cost Allocation Requirements

The order establishes cost allocation principles for new regional and interregional transmission facilities included in regional plans.  The principles ensure that allocated costs are “roughly commensurate” with estimated benefits. Order 1000 allows different allocation methods for different types of transmission facilities.  It also allows allocation of costs to a neighboring region only if the other region agrees.

Transmission Developer Qualification and Selection

To promote competition in regional transmission planning, Order 1000 requires the removal of federal rights of first refusal from Commission-approved tariffs and agreements for new transmission facilities.
