The Federal Energy Regulatory Commission granted October 11 additional time for electricity transmission owners and regional organizations to file compliance plans to Order 1000, a historic rulemaking aimed at building long-distance transmission lines and promoting renewable generation. The transmission planning and cost allocation rule would require more regional planning for building transmission; would require transmission owners to take into account public policy goals like renewable generation targets; would eliminate preferences for incumbent utilities; and would spread the costs of new transmission lines across more customers and states. Industry stakeholders have challenged the rule in federal court, contending that the commission has exceeded its authority under the Federal Power Act.
