Siting electric transmission lines across state borders has long been a challenge for the states, the federal government and utility transmission companies. Too often, the diverse interests of various stakeholders, combined with the absence of a mechanism capable of bringing different entities together, makes siting interstate electric transmission lines a difficult proposition. The compact option model provides a compromise that allows state policymakers and federal officials to work collaboratively to site lines in a timeframe that would be beneficial to all parties. If implemented, a compact can provide states a durable tool that allows collaboration across state lines and partnerships with federal agencies to ensure stakeholders’ interests are met.
