TranServ as Independent Transmission Organization (ITO) completed a Transmission Service
Request (TSR) System Impact Study (SIS). This study identified constraints to providing the
requested service that resulted in the need for both direct assignment facilities and network
upgrades. Therefore, the Facilities Study Agreement was issued.
The LG&E and KU Open Access Transmission Tariff (OATT) states that the Facilities Study will
include a good faith estimate of (i) the cost of Direct Assignment Facilities to be charged to the
Eligible Customer, (ii) the Eligible Customer’s appropriate share of the cost of any Network
Upgrades, and (iii) the time required to complete such construction and initiate the requested
service.
LG&E and KU Transmission initially performed a Facilities Study for the subject request that was
submitted to the customer in July 2015. After review of the Facilities Study report the customer
recommended an alternate solution to mitigation of the identified constraints. In accordance with
19.6 of the OATT, the Facility study was reopened. This report details the required new Facilities
and Facilities upgrades identified through evaluation of the proposed option. TranServ has
reviewed the Facilities Study results and draft Facilities Study Report from LG&E and KU and
prepared this final report in accordance with the LG&E and KU OATT.

2. Facilities Study Results from LG&E and KU
TranServ completed a TSR SIS and identified the following thermal and voltage constraints in
Table 2-1 for providing the requested transmission service for the subject request. LG&E and KU
performed a Facilities Study and determined that mitigation of the thermal and voltage constraints
can be achieved through installation of direct assignment facilities and network upgrades.

2.1 Direct Assignment Facilities
There are direct assignment facilities required at Morganfield to accommodate the installation of
a 69 kV radial circuit from the delivery point to Morganfield substation.
Table 2-2 breaks down the required projects, and provides cost estimates and anticipated inservice dates:

The cost estimate for direct assignment facilities is $1,284,000 USD.
2.2 Network Upgrades
TranServ completed a TSR SIS and identified thermal and voltage constraints for providing the
requested transmission service for the subject request. LG&E and KU performed a Facilities
Study and determined that mitigation of the thermal and voltage constraints can be achieved
through installation of network upgrades in combination with the direct assignment facilities
discussed in the section above. Table 2-4 breaks down the facilities which can be mitigated
through network upgrades. The numbers in the Mitigation column correspond to the project
descriptions in Table 2-5. Table 2-5 also includes the cost estimate for each mitigation and the
anticipated in-service date.

*Total cost of the project is estimate to be $4,500 USD. The cost of the two year advancement
is estimated to be $422 USD.
The total cost estimate for network upgrades is $6,464,420 USD. The Transmission Customer’s
share of the Network Upgrades cost is $0 USD.
2.3
Project Completion Timeframes
The time frame required for Engineering, Procurement, and Construction of the necessary
facilities is provided in the Tables 2-2 and 2-4 above. It is anticipated that the majority of the initial
projects will not be completed until 2017, which is beyond the 2015 and 2016 need dates
discussed above. The Transmission Customer’s load is currently served from a radial, which
eliminates the possibility of an operating guide. As such, the maximum load that can be served at

the Transmission Customer’s existing delivery point is approximately 31 MW (98% power factor)
during the interim period. This load level was tested assuming that the breaker on the high side
of the Morganfield 161/69 kV transformer could be in place prior to Summer 2016.
