Transmission Transmission AssessmentAssessment
Loadings increasing$$ and weather are the driversMore curtailments requiredNot designed for current levels and directions of transfersMost planning is short termMargins are thin

Few Few Transmission Transmission AdditionsAdditions
Only 7,500 miles plannedMost additions driven by need to connect new generatorsNo significant improvement to long-distance transfersLess weight place on reliability in justifying transmission

Previous Previous RecommendationsRecommendations
Reasonable time frames and deadlinesClear decision criteria, need standards, and rules for cost recoveryEarly involvement of landowners, public, and regulatorsOne-stop siting and certification processCriteria for preferred sites - corridorsRegional or federal siting authority

Maintaining Maintaining TransmissionTransmissionas an Optionas an Option
Must change how transmission is certified and sited
Recognize multi-state nature and benefits of transmission in siting and certification processesRegional siting authorities?Role for RTOs?Federal role in siting?
Unless processes changed, major transmission will simply not be developed!

The ChallengeThe ChallengeConcerted and cooperative effort to reform siting processesAll know what has to be doneUnless processes are fixed, will continue to work around congestion and constraints
