Towers for the power

Thumb loop route should be finalized by early spring

UPPER THUMB —
Transmission officials say the route of the new “Thumb Loop” transmission line project will be finalized early next spring, at the latest.

“We filed the route application with the (Michigan Public Service Commission) MPSC, and they’re going through the six-month process defined in Public Act 295 for expedited connection transmission line siting for wind development,” ITC-Transmission Senior Capital Communications Specialist Joe Kirik told the Tribune.

ITC Transmission’s application for an expedited siting certificate for a transmission line is part of a process established by Michigan’s Clean Renewable and Efficient Energy Act of 2008 (Public Act 295), in effort to facilitate future wind energy development in Michigan. The law requires the creation of wind energy zones and expedites transmission siting to facilitate wind energy generation in those zones.

Following the law’s passage, the Michigan Wind Energy Resource Zone Board (WERZ Board) identi­fied four areas around the state as potential wind energy zones. The four regions the board identified as having the highest level of wind energy harvest potential included Region 4 in the Thumb, which consists of parts of Huron, Bay, Saginaw , Sanilac and Tuscola counties.

Based on the WERZ Board’s final report, the MPSC issued an order Jan. 27 accepting the board’s report and establishing Region 4 as the “primary wind energy resource zone,” and designated Region 1, which is located in Allegan County , as an additional wind energy resource zone. Prior to that order, ITC Transmission, Michigan Electric Transmission Company and Wolverine Pow­er Supply Cooperative, Inc. filed a joint report identifying the existing transmission infrastructure and the new transmission infrastructure necessary to deliver the maximum and minimum wind potential identified by the WERZ Board in each of the four regions. In that report, it was indicated extensive backbone transmission facilities would be required to support the minimum and maximum wind potential in the Thumb region.

ITC proposed creating the Thumb Loop high-voltage electric transmission line project to serve as the backbone transmission system needed to deliver wind power from the Thumb area. The proposed Thumb Loop project received approval from the Midwest Independent Transmission System Operator (Midwest ISO) on Aug. 19.

Following that approval, ITC filed an application with the MPSC requesting an expedited siting certificate to construct the Thumb Loop transmission project, which includes a new 345 kV double circuit tower line and four new substations, according to the application ITC submitted to the MPSC Aug. 30.

“ ... ITC Transmission plans the construction of a transmission line running from the southwest side of Michigan’s Thumb region in Tuscola County to the northcentral area of the Thumb in Huron County, then running south through Sanilac County and ending in St. Clair County,” ITC’s Aug. 30 application states.

Two proposed routes


There currently are two routes that have been submitted by ITC to the MPSC. The proposed route runs through the following townships: Tuscola , Denmark , Gilford, Fairgrove, Akron , Columbia , Sebewaing, Brookfield , Winsor, Oliver, Colfax, Verona , Sigel, Paris , Minden , Wheatland, Custer, Sandusky , Watertown , Washington , Buel, Fremont , Greenwood , Kenockee, Wales and Columbus , and possibly a portion of the City of Sandusky .

The alternate transmission route submitted to the MPSC runs through the following townships: Tuscola, Denmark, Juniata, Fairgrove, Almer, Columbia, Elmwood, Elkland, Grant, Sheridan, Colfax, Verona, Sigel, Bingham, Austin, Argyle, Moore, Custer, Sandusky, Watertown, Elk, Speaker, Fremont, Greenwood, Kenockee, Wales and Columbus, and possibly through the City of Sandusky.

Once the route is finalized and approved by the MPSC, ITCTransmission will contact landowners along the route and begin discussions about obtaining easements ITC needs for the line, Kirik said.

The cost, local tax revenue


Kirik said ITC estimates the Thumb Loop project will cost $510 million.

As to who will foot the bill, Midwest ISO in June filed a proposed cost allocation methodology for new transmission project with the Federal Energy Regulatory Commission (FERC). If approved, Multi Value Projects — which are transmission projects that have a regional impact and are part of a regional plan — will have a 100 percent regional allocation of costs under the proposed methodology.

Jennifer June, of the Midwest ISO, said the Thumb Loop project is considered a Multi Value Project, and if FERC approves the Multi Value Project cost allocation methodology, the cost of the Thumb Loop project will be shared across the 13 states in the Midwest ISO footprint. She said it’s expected FERC’s approval will come in mid-December.

Kirik said ITC estimates the company will pay several million dollars in property taxes in total every year for the project’s 140 miles of lines and four substations.

The amount of taxes ITC will pay begins at 100 percent of assessed value, then depreciates 3 to 4 percent a year over 15 years, he said. The amount ITC pays in taxes will stop depreciation at a minimum assessment of 50 percent.

Project timeline


The Thumb Loop most likely will be built in stages, with a final completion date of 2015, Kirik said.

“We anticipate the first segment will be built on the western side of the loop — from Tuscola to Huron (counties) — (and that) could enter into service as early as late 2013,” he said. “The remainder of it would be targeted for completion sometime in 2015.”

While the process of upgrading transmission capabilities has been expedited to facilitate renewable energy projects, so 10 percent of the state’s energy comes from renewable resources by 2015, the improved grid will be able to accommodate other sources of energy generation.

Because ITC is a federally- regulated independent transmission company, it has to be “generation and technologically neutral,” meaning it has to provide all forms of generation access to the grid, Kirik said.

“Gas, wind, solar, coal — whatever it may be — we cannot and do not discriminate based on type of generation transmission,” he said. “So it’s an open grid from our standpoint.”

The Thumb Loop project will benefit the entire area, Kirik said.

“It makes the system stronger and more reliable, and it establishes more and better connections to other parts of the grid,” he said. “ ... The higher the voltage, the more efficient the system is. We have a lot of lines in Michigan at this voltage, so it’s a very common type of line for us. Again, it helps strengthen the entire local and regional grid, which allows power to flow more freely.”
