General Description

Summary East Point Collector Substation will be designed and built to collect roughly 50MW of PV solar power

located in upstate New York and transmit to a nearby 69kV interconnection point. The 110’ x 144’

substation yard will consist of two (2) incoming 34.5kV collector line feeders, each with circuit breaker

protection feeding onto the substation bus and through a 69-34.5kV Power Transformer with associated

69kV high voltage circuit breaker, disconnect switches, instrument transformers and revenue metering.

AC Station Service

Design Criteria The AC station service system shall be sized to accommodate all new and known future substation AC

power requirements. AC Station service will be established from two independent sources.

The Primary station service will originate from the 34.5kV bus and feed a single phase 25kVA

transformer. A 240/120V grounded-wye, 1 phase, 3 wire secondary will be derived and used as the

Primary station service.

The Alternate station service will originate from a nearby distribution line or emergency generator and

will be selected during the detailed design process.

An automatic transfer switch (ATS) will be installed and fed from the two independent station service

sources.

Substation Lighting

Design Criteria All interior building and exterior yard lighting will be designed per NextEra Energy or applicable

industry standard. Outdoor Yard lighting designed to a 2.4 foot-candle average, and will be building

wall, and pole structure mounted. Light fixture maintenance can be accomplished with equipment / bus

in service by qualified personnel.

Materials • Building Entry Light, Wallpack, 70W, HPS, with Full Visor

o Lithonia TWA-70S

• Floodlight, 250W, HPS

o Lithonia TFLU-250S

Direct Stroke Protection

Design Criteria A three (3) 60ft. lightning mast will be utilized for the direct stroke protection. The analysis of then

lightning protection for the substation yard will employ IEEE-998 “Rolling Sphere method” for the

69kV voltage level and “Fixed Angle method” for the voltages below 69kV.

Grounding

Design Criteria

The fault current that will be used for grounding system design will be based on 20 kA. IEEE-80

Standard current split factor will be used to determine the return ground current.




Page 8 of 8

Subgrade Grounding A 4/0 (19 strand) copperweld conductor will be installed 18” below finish yard grade. The 4/0

conductor will be arranged throughout the yard in an overlapping rectangular grid pattern, extending 3

feet beyond the fenceline (including gate swing radius), with 20 foot by 20 foot spacing as determined

by design software. The grid spacing will be closer in the proximity of electrical equipment, and will be

connected at all conductor intersections. Two (2) steel copper clad ground rods ¾” x 10’, with threaded

couplings will be installed as dictated by design software and client standards throughout the yard area

connected to the 4/0 grid, to enhance the grid system’s effectiveness, by penetrating into stable & lower

resistivity unfrozen soil layers. The sub-grade ground grid connectors will be the “Hyground irreversible

compression system” type - as manufactured by Burndy. All group operated airswitch mechanisms will

have personnel protection mats below grade (installed with 4” of crushed stone cover) at each operating

mechanism location. This protection mat will be connected to the operating handle, and to the ground

grid to maximize personnel protection from touch potentials. Connected pigtails (4/0 ) extending from

the subgrade grid to the base of equipment structures, and stands will bond all above grade facilities.

The below grade grounding conductor will loop around yard structures. The substation yard finish grade

will consist of a 4 inch layer of coarse crushed rock (3,000 OHM-meter), which is considered for safe

yard step and touch potentials.

Structure & Equipment Grounding Ground grid pigtails will connect to the base of structure legs using bronze bolted or copper compression

clamps as required at each leg for single and double leg structures, or at diagonally opposite legs for four

leg structures and stands. Bronze mechanical connectors will also support jacketed 4/0 copper

conductor to be run along structures and stands for grounding of equipment casings, surge arresters,

ground switches, and overhead shield wires.

Where aluminum structures are used, bolted connections will be used and connections will be plated to

accept copper conductors. Copper conductors shall be covered in solid dielectric insulation to avoid

dissimilar metal corrosion from the contact of aluminum and copper.

All above grade equipment will be properly bonded to the station ground grid using a continuous

conductor path.

Fence Grounding The substation perimeter fence posts will be bonded using 4/0 copperweld pigtails from the station

ground grid at regular intervals, and where each overhead transmission phase conductor (if applicable)

crosses the fenceline with bolted bronze pipe-type mechanical connectors. Fence corner and gate posts

shall be bonded directly to a ground rod. Gate frames and top rails will be bonded with 1/0 stranded

copper, with the gate frame using a high strand 600V welding cable for maximum flexibility.

Grounding of the chain-link fence, barbs, and bottom tension wire will be completed with a #2 stranded

bare copper conductor and tinned bronze split bolt mechanical connectors.
