Xcel cuts Hiawatha substation artwork by half to reduce costs

-->
Midtown Greenway Coalition offers alternatives that would prioritize trail users, but Xcel is proceeding with reduction



by Tesha M. Christensen

The new 3.25-acre Xcel substation at Hiawatha and 28th Ave. will no longer be screened on all sides by angled aluminum mesh walls.
Instead, Xcel is cutting back the amount of artwork on the facility by about half, a move that the Midtown Greenway Coalition says will negatively affect trail users.
“The last minute change to the substation design was a surprise and very disappointing,” said Midtown Greenway Coalition Executive Director Soren Jensen. “We were excited about the original design, which was approved by a citizen advisory group convened by Xcel. That original design had artwork wrapping almost entirely around the substation.”
When the design for the new substation was released in 2012, it garnered praise for being a unique and creative structure. The design was of a translucent cube that would glow yellow at night, complementing the blue-lit Sabo Bridge nearby. The plan was to have all four walls composed of extruded metal, a metal mesh surface that is semi-transparent. The metal would be given an anodized finish to color it. Additional color would come from lighting.
The advisory work group pushing designers to be creative included representatives from Xcel Energy, the city of Minneapolis, Hennepin County and community organizations. The group met for four months and conducted several open houses, working to develop a substation design that would be technically feasible and aesthetically pleasing, according to Xcel representative Patti Nystuen.
After the group met, an engineering and budget analysis was completed. The designs filed with the Minnesota Public Utilities Commission had reduced and re-engineered screening on both the Hiawatha substation, as well as the one on Oakland Ave. and 29th St.
“These revisions were necessary to meet safety and budget concerns of the original designs,” said Nystuen. The Minnesota Public Utilities Commission approved a substation screening budget for both substations of $1.3 million.
“Xcel Energy tried to keep the integrity of the originally presented design with as much of the wall as possible on all sides,” said Nystuen.
She added, “Xcel Energy feels that the current wall design respects the guiding principles established through the advisory work group and respects the interest of the participating parties in the group’s process.”
The Midtown Greenway Coalition disagrees.
“The new design, which was not approved by the citizen group, reduces the artwork almost in half.  As a result, it now looks more like a half-hearted attempt to screen an ugly substation,” said Jensen.
Xcel has received 77 comments from citizens regarding the change. All but two asked that the artwork wrap around the north/northeast corner of the substation.
“We are disappointed that Xcel appears to be ignoring public comments, and is proceeding with the new design, which greatly reduces the proposed art wall around the substation,” stated Jensen.
The Midtown Greenway Coalition is requesting that the advisory work group be reconvened by the Minnesota Public Utilities Commission to review the design.
The Coalition has proposed a number of alternatives that would not increase the project cost, but would provide artwork on the east and north sides. This would screen the substation from trail users, who come closer to the substation than drivers on Hiawatha do.
Jensen stated, “Since the substation is mostly impacting the Midtown Greenway, the priority should be protecting the Greenway viewshed and minimizing the aesthetic impact to the trail.”
Site work at the Hiawatha location behind Target has begun, and the project will be complete in 2014.

Longfellow’s newest landmark: the Hiawatha substation

The graffiti-resistent walls of the new Hiawatha substation, located behind the Target building near the intersection of 28th and Hiawatha, will be illuminated yellow at night. The walls will be composed of extruded metal, a metal mesh surface that is semi-transparent. The metal will be given an anodized finish to color it and additional color will come from lighting. “This system is unique for this type of application,” said Xcel Energy’s Transmission Project Manager Joe Samuel. The substation will be complete in 2014. To follow the project, go to www.hiawathaproject.com.



Xcel releases ‘creative and unique’ substation design

by Tesha M. Christensen

Xcel’s new 3.25-acre substation at 28th and Hiawatha will be more than a concrete box surrounded by a chain link fence. Instead, a translucent cube will glow yellow at night, complementing the blue-lit Sabo Bridge nearby.
According to Xcel Energy’s Transmission Project Manager Joe Samuel, the community input Xcel has received regarding the design has been positive, as people consider it to be “a creative and unique substation design.”
The final design is the result of a collaborative process between designers, Xcel staff, and community members, noted Samuel. “The advisory group of the community really challenged the team to come up with a creative design,” observed Sanuel. Architectural Alliance developed the design schematics for the walls that will surround the new substations.
These walls will be composed of extruded metal, a metal mesh surface that is semi-transparent. The metal will be given an anodized finish to color it. Additional color will come from lighting. “This system is unique for this type of application,” said Samuel.
“I think the design is better than the standard substations found in most locations,” said Spencer Agnew of the Longfellow Community Council (LCC) who served on the advisory work group. “Time will tell whether or not it will be a positive for the neighborhood, but it is an improvement over what could have been there.”
“Our hope is to meet the needs of the community and provide a landmark feature,” said Samuel.
The substation designs will be submitted to the Minnesota Public Utilities Commission in August. The commission will have 60 days, including a public comment period, to reach a decision on the plan, which is expected in October.
ROAD CLOSURES, TRAIL DETOURS EXPECTED
The Hiawatha substation is one of two being built over the next two years by Xcel that will link a new 115kV underground transmission line. It will run for 1.5 miles down 28th Street E (an option labeled Route D during the regulatory process). The other, smaller substation will be placed at the northwest corner of Oakland Ave. S. and 29th Street.
According to Xcel, revitalization in south Minneapolis, and particularly the Midtown District, has strained the electrical supply. “The focus of this project is reliability,” stated Samuel. The Hiawatha Project will bolster existing capacity infrastructure.
The underground transmission line will be placed in a concrete duct system which will require the placement of cable vaults with manhole access every 1,500 feet and at any change in direction of the route. In July, Xcel began installing underground electrical duct systems for the electric distribution system on Portland Avenue between the Midtown Greenway and 27th Street. This work, which will be done in September, has resulted in some traffic and bicycle lane closures as well as parking restrictions. Construction of the transmission lines will be complete in the fall of 2013. During that time, there will be road closures and detours on 28th Street.
When the project is done, Xcel Energy will restore the excavated area on 28th Street with bituminous patch. The city of Minneapolis may also sealcoat or mill and overlay 28th Street in 2014.
Site work at the Hiawatha location behind Target has begun, and the project will be complete in 2014. This construction will have limited impact to traffic on the adjacent roadways.
According to Agnew, the bike trails around the Hiawatha substation will remain open during the construction; however, at times the trail will be temporarily rerouted by 10 to 20 feet.
The trees planted in the area by local residents during Arbor Day events will be removed. “Xcel says they cannot be transplanted due to possible soil contamination on the site,” said Agnew. Underground wires, rail spurs and adjacent land ownership at the site will prevent some forms of landscaping from occurring near the substation site, but what is done will be consistent with the Midtown Greenway landscaping plan. Xcel is also in discussions with adjacent landowners about the possibility of installing trees on their property.
One of the requests made by the LCC was that the substation be graffiti-resistant.  The Xcel design team feels that this design accomplishes that.
COST TO BE SPREAD OUT
The $55 million to $60 million cost of this project will be spread among Xcel’s entire five-state customer base instead of just local customers.
Xcel supported the ruling made by the Minnesota Public Utilities Commission on June 28. If Minneapolis ratepayers had shouldered the costs alone, and the project was paid for within three years, it could have led to utility bill increases of $2.83 a month, according to company estimates submitted to the PUC.
