The owner’s independent technical voice

Sonoma Creek Consulting gives power project owners, developers, utilities, and investors an independent reviewer who has built, run, and fixed the equipment being bought. Principal James C. Gilmore brings about 35 years across gas turbine generation, high-voltage substations, battery storage, solar, and wind, on EPC projects up to $215M.

Design and constructability review

Marked-up drawing sets that catch scope gaps, vendor and EPC mismatches, load calc errors, and grounding and conduit conflicts.

Power system study review

Independent review of protection coordination, short circuit, and load-flow studies before relay settings are loaded.

Construction and commissioning

Field oversight, test witnessing, punch lists, and lessons-learned logs that protect equipment and schedule.
