COGENERATION and HYDROELECTRIC

ArcSine Engineering has extensive experience in planning and design of cogeneration and hydroelectric facilities. Planning includes feasibility studies with electric (and thermal, if applicable) load analysis, conceptual design, economic analysis, and optimal system selection. Design work includes power distribution, instrumentation and controls, lighting, and peripheral systems. Both planning and design efforts include coordination with the serving gas and electric utility. We also perform services during construction including submittal reviews, coordination with contractors, inspection, and assistance with startup. Following is a partial list of ArcSine projects.

Performed electrical design, including short-circuit calculations and coordination of protective devices, and assisted with startup of a 12-megawatt synchronous generator project in Chester, California.

• SANTA ROSA COGENERATION PROJECT

Field investigation, analysis, and conceptual design of a 60-kilowatt plus 30-kilowatt cogeneration system to feed community center electrical loads and heat a public swimming pool and domestic water.

• ENTERPRISE HIGH SCHOOL COGENERATION PROJECT

Field investigation, analysis, and conceptual design of a 60-kilowatt cogeneration system to feed school electrical loads and heat the swimming pool. To minimize extensive connection provisions particular to the serving electric utility, the system included a dual-rated cogeneration unit and special controls.

• SHASTA HIGH SCHOOL COGENERATION PROJECT

Field investigation, analysis, and conceptual design of a cogeneration system to serve a high school campus with seven independent electric services.

• SEWARD HYDROELECTRIC PROJECT

Performed preliminary electrical design for a 25-kilowatt induction generator project for the City of Seward, Alaska.

• BOULDER CREEK HYDROELECTRIC PROJECT

Performed the electrical design for a 320-kilowatt synchronous generator hydroelectric project in Pablo, Montana.

• BAILEY CREEK HYDROELECTRIC PROJECT

Performed electrical design for a 720-kilowatt synchronous generator project in Manton, California.

• WINCHESTER HYDROELECTRIC PROJECT

Prepared detailed performance specifications for two 750-kilowatt induction generators for a project in Roseburg, Oregon.

• ARBUCKLE MOUNTAIN HYDROELECTRIC PROJECT

Performed preliminary electrical design of a 350-kilowatt synchronous generator project in Platina, California.

• McMILLAN HYDROELECTRIC PROJECT

Performed the electrical design for a project in Round Mountain, California, utilizing a 160-kilowatt synchronous generator plus several smaller induction generators.
