Rock Island Clean Line HVDC Transmission
The Rock Island Clean Line will deliver 3,500 MW of renewable energy from the region of Iowa, Minnesota, Nebraska and South Dakota to markets in Illinois and states further east. Power will be delivered via a 500-mile, 600 kV overhead High Voltage Direct Current (HVDC) transmission line at a cost of $1.7 billion. The Clean Line Energy team sought to study and review a wide range of alternatives consistent with all federal, state and local laws and regulations to determine suitable study corridors. Our role was to provide support for siting, permitting, public involvement and stakeholder outreach.
Our environmental review included potential impacts to residences, agricultural land, state and federal lands, recreational areas, water resources, known cultural resources, sensitive habitats and protected species. Engineering considerations, such as corridor width, clearances over man-made obstacles and the type of terrain that may be traversed, were evaluated. We are developing the potential routes for state (IA and IL) and federal permitting approval based on information obtained during the review. With the understanding that a high level of public involvement and stakeholder outreach would be needed, we crafted a strategic approach aimed at engaging resource agencies, local governments, NGOs and the public throughout the project's duration. The first round of public meetings were highly successful. We developed all public meeting and marketing materials, and arranged logistics for a total of 26 meetings.
Rock Island is expected to be placed into service by 2016.
