Sheridan’s 5th Street Expansion

a real HOT spot for large Data Centers.

Sheridan’s Best Location for big electric users needing cheap juice.

As referenced within the “TMNG Global”, Infrastructure and Site Readiness Assessment for Data Center, report Sheridan’s best location for attracting a large or very large data center is just east of I-90 on 5th Street/Wyarno Road and E. Ridge Road Area.

This area, which currently has a State Of Wyoming planned facility, is within 1 & ½ mile of the Regional Power Grid Substation, has regional 230kV power lines, MDU has 230kV and 41.6kV power lines with immediate access to looped capacity potentially as high as 75 to 90mW. This area also has both ACT and CenturyLink fiber, good roads (E. Ridge Road currently being extended south), 12” high pressure looped water line and at least a 10” waste water line.  The terrain is generally flat which would make for moderately easy construction.  City Hall is ready to annex and extend utilities upon commitment of a data center client to locate.

The City and environs are currently provided with power from a regional grid over Rocky Mountain Power (RMP) and Montana Dakota Utilities (MDU) 230kV Transmission Lines (Regulated by the Western Area Power Authority – WAPA). This grid provides power via a major substation (Sheridan PP&L Sub) located just North East of I-90 and 5th Street and is comprised of at least 3 looped feeds tied into numerous power plants developing over 2,000MW of power. This network provides a substantial level of reliability. (See Exhibit 1).

Quadrant Power Grid For the city as a whole MDU has a combination of 230kV and 41.6kV transmission lines in a couple of small loops in the downtown area and a large loop surrounding the city and tying back into the Sheridan PP&L substation.  This design offers looped service to much of the local market.

Sheridan Substation | (called Sheridan PP&L Sub) is part of three (3) 230kV looped routes creating a substantially robust or reliable grid.

Current expansion plans include extension of the 41.6kV transmission line service into the Sheridan Hi-Tech Business Park and the Wrench Ranch area (See Exhibit 3).  Within this expansion are newly constructed transmission lines and substations to create a loop through the Business Park providing 10MW to 20 MW of looped or “protected” power.

Within the City of Sheridan, ACT’s core access network consisting of a 2.5 Gbps SONET Ringed network supports traditional TDM based services such as Digital Signal level 1 and 3 (DS-1/DS-3) and Optical Carrier Services at OC-3 (155.52 Mbps) and OC-12 (622.08 Mbps).  For the delivery of Ethernet services, ACT has deployed a ringed “protected”10 Gbps network for support of copper based Digital Subscriber Line (DSL) services at data rates up to 50Mbps and Fiber to the Premise (FTTP) at data rates up to 1 Gbps.  Ethernet services are delivered over Passive Optical network (PON, Active Ethernet (AE) or Carrier Ethernet equipment to the customer’s premises.  The local city-wide network can easily be augmented to provide one or more 10Gbps protected circuits or lease/IRU fiber that interconnects with ACT’s protected regional network.
