Report
Summary
The contract amendment with SRP is for design and construction services for installation of a 69kV bus divider breaker and associated equipment for the Tres Rios Substation at the 91st Avenue Wastewater Treatment Plant for the Water Services Department. This substation does not currently meet SRP standards for isolated redundancy and is at risk of experiencing power failure which would result in a complete plant shutdown. SRP responsibilities under this contract include installation of a new 69kV bus driver breaker including the purchase of equipment, design and construction. The additional divider breaker will split the 69kV bus into two segments to provide relay protection per SRP standards for adequate redundancy and protection for the 69kV system.
Contract Term
The original contract term is for five years with one automatic one-year renewal effective Oct. 2, 2014, through Oct. 2, 2020.
Financial Impact
Funding for this amendment in the amount of $1,341,525 is available in the Water Services Department's Capital Improvement Program budget.
