Over the coming months two major public service transmission lines will be installed across Pope county. One is a high voltage direct current (HVDC) electric transmission line from the panhandle of Oklahoma to Memphis, Tennessee. The other is a pipeline to move oil from Cushing, Oklahoma to Memphis. One will contribute to a clean energy future, the other will contribute to global warming. Both will, to the point of law suits, incense landowners along the rights of way.
Cushing Oklahoma, because of location and historical precedent, is the major hub for oil pipelines in the United States. It also happens to have the largest oil storage tank farm in the world. The Diamond pipeline will move 200 thousand barrels of light sweet crude per day to a Valero refinery in Memphis. To get a sense of just how much oil that is, if the pipeline were diverted it could fill the Dallas Cowboys stadium in less than a day. If the oil were all converted to gasoline, it could fill the tanks of half a million cars a day.
Opposition to this 900 million dollar project comes from landowners who would rather not have a 25 to 150 foot wide strip of land which must be maintained as an open space – no forestation or permanent structures in the right of way. The pipeline is also opposed by environmental groups who would rather not have more crude oil turned in to fuel which ultimately contributes to global warming.
The panhandle region of both Texas and Oklahoma have some of the best wind resources in the country. Wind speeds average near 20 miles per hour. It is a problem however as there is no market for all the potential wind energy in the area, hence the need for transmission lines to take what energy could be generated elsewhere. Most practical is transmission to the east across Arkansas to a distribution hub in Memphis. This will allow for clean renewable energy to replace energy from coal fired power plants across the Tennessee Valley Authority power grid. It also will require a 150 or so foot right of way.
The HVDC transmission line will carry 4,000 Megawatts of direct current electricity about 700 miles start to finish. Power poles are 150 feet tall and spaced 5 to the mile. This power line is like a super highway for electrons with very limited access. The only “drop-off” point planned currently is an off ramp near Atkins. This will allow 500 Megawatts of power to flow into the local grid.
Like the oil pipeline, land owners are opposing the HVDC line. The nation’s preeminent environmental group, the Sierra Club, is supporting it.
Both project require regulatory oversight which allows the use of eminent domain to secure the rights of way. The process is different for the projects. The oil pipeline has been approved by the Arkansas Public Service Commission (APSC) even though the Pipeline will provide no direct benefit to Arkansas. Apparently pipelines get a legal pass, not afforded to the electric transmission lines.
Because the initial HVDC line had no direct benefit to Arkansas, it was denied legal status by the APSC and therefore is seeking federal oversight. By partnering with the Department of Energy Clean line will gain federal right of eminent domain.
