Clean Line strives to develop the Plains & Eastern Clean Line in a manner that is fair to affected Oklahoma landowners and respectful of their property rights. Clean Line has attempted to contact affected landowners in Oklahoma to inform them of the project, seek input and request their voluntary permission to perform ongoing studies and field surveys that support environmental and permitting requirements. Clean Line representatives are available to answer questions and address concerns.  Please contact us, and we will respond promptly.

Development of a major infrastructure project requires coordination and review among several entities. The Department of Energy (DOE), in coordination with the Southwestern Power Administration, has completed an extensive environmental review of the Plains & Eastern Clean Line pursuant to the National Environmental Policy Act (NEPA). Numerous Oklahoma state agencies gave input on the routing of the project and the NEPA process, including the Oklahoma Department of Wildlife Conservation, Oklahoma Tourism and Recreation Department and Oklahoma Department of Transportation.

On October 28, 2011, the Oklahoma Corporation Commission (OCC) approved Plains and Eastern Clean Line LLC’s request to conduct business as a public utility in Oklahoma.  As an Oklahoma public utility, Clean Line can construct, own, and operate electric transmission lines within the state.  To learn more about the filing, please click here.

Frequently Asked Questions

How will this project benefit Oklahoma?

The project will bring significant economic development, by creating the opportunity for thousands of construction jobs and hundreds of operations jobs to build and maintain the transmission line and wind farms. The Plains & Eastern Clean Line will also make possible billions of dollars of investments in new clean energy projects that could not otherwise be built due to the limitations of the existing electric transmission grid.

Local communities will benefit from increased revenues from both the transmission line infrastructure and supporting wind farms. According to the U.S. Department of Energy’s Final Environmental Impact Statement, in the first year of operation, Clean Line will pay an estimated $13 million in ad valorem taxes to Oklahoma counties and rural communities where the electric transmission project is located. Payments would continue to be made annually for as long as the line is in service and would support local schools and other community services. In addition to these payments, Clean Line has also committed to pay more than $3 million in voluntary infrastructure payments to counties in Oklahoma.

Clean Line estimates it will make over $35 million in payments to Oklahoma landowners for easements, structure payments and other compensation.  Landowners will be able to continue farming the land within the easement and may use the property in other ways that are compatible with the electric transmission line. 

In addition, businesses like Pelco Structural and Siemens that are involved in the wind energy and transmission supply chains will see increased demand for their products and services as a result of the construction of the project and associated wind farms.

Citizens across the region will benefit from cleaner air as a result of the new wind energy enabled by the Plains & Eastern Clean Line project, as that energy will displace more polluting forms of electric generation.

Will this affect my electric bill?

It is not likely that utilities in Oklahoma will buy wind power from the Plains & Eastern Clean Line as they are so close to strong wind resources and do not need to use the Plains & Eastern Clean Line to access affordable clean energy. Because of this, based on current regulations we do not see any costs from our project being borne by Oklahoma rate payers.

Will the Plains & Eastern Clean Line reduce property values?

Every landowner’s property is different, and without knowing all the specifics it is difficult to say definitively what impact, if any, the proposed transmission line would have on a property.  However, the relationship between transmission lines and property values has been the subject of systematic research for nearly 50 years. Clean Line commissioned Tom Priestly to perform a review of this body of research. His review concluded that these studies show that being close to electric transmission lines can have little or no negative long-term effects on residential property values, with average impacts ranging from no effect on value to a decrease in value of up to 10 percent. To see a full copy of the report, please click here. All that said, landowners will be compensated for 100% of the fee value of the land in which the easement area is located and will receive additional payments if they have structures on their land.

When will Clean Line be in the field conducting surveys?

Beginning in May 2016, Clean Line will conduct field surveys for the Plains & Eastern Clean Line transmission project with a focus on the identification of aquatic, biological, and cultural resources.  Multiple contractors and subcontractors will be working across the project area in Oklahoma, Arkansas and Tennessee to support this effort. Land agents for Plains & Eastern are contacting landowners to obtain survey permission, provide notification of survey activities, and answer questions.  Clean Line is only surveying parcels where voluntary, written survey consent was granted. Clean Line will reach out to landowners in advance to notify them of the survey activities.

If you have any questions about the project or the surveys Clean Line is conducting, please call one of our project representatives toll-free at (877) 573-2851 or email us at info@plainsandeasterncleanline.com.
