A greenfield substation, delivered on plan
An electric cooperative is building a new 115 kV substation, plus the transmission and distribution work around it, to serve fast-growing load. They needed one firm keeping design, procurement, and construction moving as a single program. Our team serves as the owner’s program manager and engineer.
WHAT WE CARRY
- Master schedule across substation, transmission, and distribution
- Procurement of the power transformer, relay panels, reclosers, and switches
- Coordination of the design, protection, geotechnical, survey, and construction firms
- Monthly cost control the board can read in one page
- Commissioning plan through energization
The board sees where every dollar and every week stands, reconciled to the penny, every month.
WHERE IT STANDS
Foundations are in, steel is standing, and the transformer sets this fall. The program is tracking to an energization target of year end.
BOTTOM LINE
- A client needed a substation built without surprises.
- Our team runs the program like the money is our own.
Ten feeders, eight breakers, zero surprises
A public utility district built a new 115 to 12.47 kV substation with an 8-position ring bus and ten feeder getaways. Our team provided the owner’s commissioning: relay testing, design review, drafting, and the troubleshooting that keeps an energization date honest.
RELAY AND CT TESTING
We wrote the relay test plans, then performed relay testing, logic verification, and current transformer testing at every position.
DESIGN REVIEW
Acting as the client’s engineer, we reviewed and corrected relay design submittals, calculations, time-current coordination, logic packages, and controller settings before they reached the field.
On a ring bus, one unverified interlock does not cause an outage. It causes a sequence of them.
COMMISSIONING
We developed and ran commissioning procedures for batteries, breakers, LTCs, logic schemes, SCADA, and the power transformers, through energization.
BOTTOM LINE
- A client needed a complex substation proven before it carried load.
- Our team tested every trip path and signed our name to the results.
