Reactor Bank Circuit Switcher Upgrade Project: This project will upgrade the circuit switchers on reactor banks at the Marion, Fayetteville and Kendall substations. This project was recommended in the FY FY 2012 TSIP and is complete and available for operations. The project is in Fayette and Guadalupe counties. Relay Communication System Upgrades Project: This project will upgrade relay/scada communications at 36 substations. The upgrades to the Fort Mason and Gillespie substations are complete. The remaining substations are located in Mason and Gillespie counties. This project was recommended in the FY TSIP, and is scheduled for completion by December Spill Prevention Control and Countermeasure (SPCC) Project: This project will evaluate 103 existing substations to develop site specific engineering plm for secondary oil-spill containment. A variety of containment methods will be utilized including concrete moats, catch basins and additional gravel. This project is required to meet amended U.S. Environmental Protection Agency (EPA) regulations that require diversionary drainage controls for potential oil spills in substations. Engineering and construction are in progress. This project was approved at the February 2003 LCRA TSC Board meeting and is scheduled for completion by summer This project is located in various counties. Substation Battery and Battery Charger Upgrades Projeck This project will replace obsolete substation batteries and battery chargers at 10 substations and add battery houses to six substations. Engineering, material procurement and steel fabrication are in progress. This project was recommended in the FY TSIP and has in-service dates of June 2004 for four substations and June 2005 for the remaining six substations. This project is located in various counties. Substation Site Upgrades Project: This project consists of adding gravel, road base and fill material to 14 existing LCRA TSC substations. Preliminary engineering is in progress.
