LCRA Transmission Services Corporation (TSC) on June 5 filed with the Public Utility Commission (PUC) of Texas an application to amend its certificate of convenience and necessity for the proposed Fayette Power Project (FPP) 345-kV Bus Tie in Fayette County, Texas.
The proposed project is a new 0.26-mile, single-circuit, 345-kV bus tie between the existing FPP substations (Yard #1 and Yard #2) located at the FPP generation facility in Fayette County, the company said. The new bus tie would modify the termination of an existing 345-kV bus tie between those two substations. The company also noted that the proposed project is located on property jointly owned by the Lower Colorado River Authority (LCRA) and the City of Austin, adjacent to the existing FPP generating units.
The bus tie associated with the proposed project and an upgrade of the existing bus tie (T405) between the Yard #1 and Yard #2 substations would result in the two yards being connected by two 1,400-foot bus ties instead of one. LCRA TSC also said that it selected single steel pole structures as the recommended structure type for the proposed project due to the space constraints within the project area.
At Yard #1, LCRA TSC said that it would reconfigure the bus work to accept an additional bus tie connection to Yard #2. LCRA TSC noted that it would install in Yard #1 two EHV “A” frame dead ends, three coupling capacitors with voltage transformers, three 345-kV surge arresters, and one control panel. In addition, LCRA TSC said that it would replace eight 345-kV switches, one control panel, and one motor operator.
At Yard #2, LCRA TSC said that it would redesign the bus work for an additional bus tie connection to Yard #1. LCRA TSC said that it would install in Yard #2 one EHV “A” frame dead end, two coupling capacitors with voltage transformers, six 345-kV surge arresters, and one control panel. LCRA TSC also said that it would replace 10 345-kV switches, one 345-kV circuit breaker, one control panel, and two motor operators. LCRA TSC noted that it would also refurbish four 345-kV circuit breakers.
According to the estimated schedule, if approved, right of way and land acquisition would begin and be completed in October; engineering and design would be completed in January 2018; material and equipment procurement would begin this month and be completed in March 2018; construction of the facilities would begin in November and be completed in May 2018; and the facilities would be energized in August 2018.
Among other things, LCRA TSC said that the estimated total cost of the transmission facilities would be about $1.2m, and about $3.7m for the substation facilities.
