Multi-year/multi-phase project added two 4-bank 500/230 kV single phase transformers, and replaced a 230/69 kV three phase transformer. The design included a breaker and a ½ scheme for both 500 kV and 230 kV designs, adding four 500 kV breakers, 230 kV breakers and change out of 69 kV breakers and associated switches. Expansion also required new local and Florida Department of Environmental Protection (FDEP) permitting, along with new SWPPP and SPCC plans.
Designed over a dozen greenfield 69/13 kV Distribution Substations in less than six years using the customers’ unique design standards. Civil designs included local, FDEP and Florida Department Of Transportation (FDOT) permitting.
Designed a 230 kV line terminal power plant interconnect addition. The addition was in accordance with Investor Owned Utility (IOU) requirements.
Expansion design of a 230 kV six position ring connection via Transmission lines, and converting the 230 kV to a breaker and a ½ scheme. The project included installation of a second 230/69 kV transformer, expansion of a 69 kV breaker and a ½ layout, and the design for a future breaker and a ½ scheme.
Replaced three 115 kV 1200 Amp OCBs with 2000 Amp SF6 breakers. Project also included replacement of eight Gang Operated Air Break switches with new 2000 Amp switches.
Engineered Substation Construction Standards and created Manuals that included customer specific requirements for design and arrangements for 138/13 kV Distribution Substations. The Standards and Manual were subsequently expanded to include 230 kV and 345 kV structures.
Designed capacitor bank installations consisting of 34.5 kV, 69 kV, 115 kV, and 230 kV ranging from 6 MVARs through 110 MVARs. Each of the installations included back to back switching arrangements. The designs included grounded/ungrounded banks, fused/fuseless/internally-fused designs, and various switching methods.
