Bass Creek Substation Bass Creek Substation, Janesville, WI Replacement of an existing 69kV Substation Project Scope: Replace an existing (2) line 69kV substation with a 69/138kV substation consisting of (2) 69kV lines, (2) 138kV lines, (1) 100 MVA 69/138kV transformer with oil containment, and a new 24’ X 36’ control building. The existing equipment was removed and the site was re-graded and enlarged. Special environmental consideration was given to an adjacent wetland area and creek. The substation equipment footprint had to be compressed as much as possible and a retention pond installed to capture storm water runoff. Major savings to the client were realized by utilizing spare equipment from various other client substations. This required extra research and confirmation that the used equipment met the requirements of the new substation and in the case of the reused steel structures, was properly modified to fit the new use. Realtime provided all engineering for the substation including; grading, grounding grid, raceways, foundations, steel structures, bus, equipment specification including a 24’ X 36’ control building, and protection and control.

Staff Substation Staff Substation, Cambria, WI New Greenfield 138kV Switching Station

Project Scope: Realtime Engineers’ involvement began with finalizing the transmission company’s Facilities Study and Exhibits within the pending generation interconnection agreement. The substation was a greenfield site, ultimately consisting of a ring bus arrangement. It is initially to be operated with (3) 138kV lines, with future expansion to (6) 138kV lines. The station will serve as a system tie between a wind farm and the local utility’s transmission grid. After about two years of planning and design, the new 138kV switchyard is into construction with an in service date of May 2011. Our original scope was to design a three termination straight bus, looping an existing transmission line through the bus and providing a tap to an adjacent wind farm collector station. Around the time of this design’s completion, our scope changed to designing a ring bus arrangement. Realtime expanded the design and completed the design package within schedule to meet the original in service date. Changing gears and incorporating the ring bus design into the construction issue saved the client about $460,000 in overall project cost. Realtime provided all engineering for the switchyard including; grading, grounding grid, raceways, foundations, steel structures, bus, equipment specification including a 24’ X 36’ control building, and protection and control. Realtime also provided the line loop-through scoping, design engineering, procurement support, and construction support for two new 90’ steel corner poles within existing ROW. We closed our work by providing new records for creation of a newly designated line. Some interesting challenges included: Coordinating efforts with the generation owner for a single, common and jointly beneficial ground grid system of the switch station and the collector substation. Also, designing an integrated SCADA communications system that satisfied the requirements of multiple Utility stakeholders. Design Completion Date: March 2011 Client: American Transmission Company Client Commentary: “… this job was done with very little confusion, minor rework, and overall a design job well done. You (Realtime) always have a quick/correct answer to the field questions and concerns… definitely made my job easier than normal. Thanks!”

500kV - 502 Junction Substation 502 Junction Substation, Mount Morris, PA New Greenfield 500kV Substation Project Scope: Realtime engineered this 500kV greenfield substation, consisting of (4) 500kV lines, designed with future expansion to (6) 500kV lines and future transformation to 138kV. This design required the movement of over 2 million cubic yards of materials, as well as removal of over 80 feet of mountain top, for the ultimate substation layout. Realtime was responsible for the engineering of the (4) line terminal 500kV switchyard, which consisted of (8) 500kV breakers installed in a double breaker-double bus configuration. Space was included for installation of a fifth and sixth 500kV line terminal, also with a double breaker-double bus configuration. The substation was also graded for the future 500/138kV step-down transformation and 138kV facilities. An approximate 40’ x 120’ metal control building was installed to house the substation electrical controls, metering, and communications equipment. The building also houses the 125VDC storage battery and charger, and is climate controlled, complete with well and septic facilities. A 52’ x 32’ maintenance building was designed and installed, as well as a separate 16’ x 24’ emergency generator building. Realtime also engineered a new SCADA system which has been installed. Additional scope included the design of a new family of 500kV steel structures, for use by the client, as standards for future projects. This project invested over three years of planning and design, and the new 500kV switchyard step down Substation for Trans-Allegheny Interstate Line Company (TrAILCo) at 502 Junction is in-service. All substation engineering, except site and grading, were performed by Realtime for 502 Junction.

138kV- Rated – Transmission Line Relocation Wausau, Wisconsin

U.S. Highway 51 & South 29 Line Relocation A Wisconsin Public Service Corporation 34.5KV distribution line needed to be relocated as a result of a Wisconsin Department of Transportation highway interchange project. Incorporating a future upgrade to 138kV, Realtime engineered five new steel-pole structures to accommodate the newly constructed overpasses. Project Scope: Realtime performed the following tasks:

• Preliminary and final design of the line alignment, structures and foundations • Coordination with the Wisconsin Department of Transportation and

Wisconsin Public Service Corporation • Steel-pole structure design and specifications • Soils investigation specifications and subcontractor coordination • Drilled-pier foundation design and construction specifications • Line construction specification • Construction documentation including PLSCADD files • Field support to construction contractors • Final project close-out

Design Challenges & Solutions: Long transmission line spans and clearance requirements over new highway overpasses lead to custom poles ranging in heights up to 115 feet. Poor soil conditions resulted in deep, large-diameter drilled-pier foundations. Total Constructed Cost Approximately: $2 million Client: Wisconsin Public Service Corporation

69kV – Manitowoc Public Utilities Transmission Line Relocation 69kV – Line Relocation for Power Plant Expansion Realtime engineering the relocation of a 69kV transmission line at municipal power plant under extremely adverse space constraints. Project Scope: Realtime engineered the following:

• Five new steel poles on foundations • Provided structural analysis • Provided soil borings and surveying • 69kV line was designed to 138kV standards • Realtime provided specifications for all of the new equipment and poles, as well

as, construction specifications for the new line Design Challenges & Solutions: This relocation project involved an already highly congested utility area, which included a complete coal-fired power plant and storm water-sewage treatment plant, bordering Lake Michigan’s shoreline. The design area was squeezed on a prohibitively narrow strip of land, adjoining these two facilities and the lakeshore. Adverse space constraints included maintaining access requirements for semi-truck traffic and railroad traffic in and out of the coal-fired plant on a narrow, tight-fitting strip of land. Design requirements included accommodating for multi-ton loads of coal and material to be driven on soil directly adjacent to the transmission line poles’ foundations. Due to the lakeshore, soil borings and geotechnical requirements were significantly more challenging. As a result of the complexities of the plant expansion, systems coordination between contractors working on the plant build-out, substation re-design, and the additional line requirements necessitated stringent communications among all stakeholders. The combination of designing in a physically congested, high-trafficked area, while meeting aggressive timeframes and budget constraints, allowed Realtime the opportunity to provide valuable design solutions to our client. Total Constructed Cost Approximately: $650,000 Client: Manitowoc Public Utilities
