  2. Is an emergency power system necessary? • Emergency • Life Safety • Legally Required • Smoke Fans • Sump Pumps • Wastewater • Optional Standby • Data Center • Risk Assessment • Mild Inconvenience to $15M for 37 seconds

  3. What are the most common standby generator set sizes? • 1000W to 2MW Diesel • 1000W to 1,250KW Natural Gas 1000W = 1KW 1000KW = 1MW 1000KW enough for about 750 homes Over 60 Years Serving California

  4. What’s involved in an emergency power system? • Generator Set • Diesel is the most common fuel source • Natural Gas in some applications • Automatic Transfer Switch 40-4,000 Amps • 3 Pole vs. 4 Pole • Isolation Bypass • Fuel System • Main Tank/Day Tank • Sub-Base Fuel Tank • Paralleling System

  5. How big does my generator set need to be ? • Actual sizing should be done, or at least verified, by a registered professional engineer • Sizing depends on the loads you plan on taking on • Size and number of motors • Lighting Loads • Computer and or UPS Loads • Elevators • How much of the facility is to be carried by the system • Are you taking on the whole building or just various emergency circuits? • Is the generator to take on all of the loads at once or will the loads be “stepped”?

  6. What are the emissions issues? • Noise • Very municipality oriented • Check with your local noise ordinances • Exhaust • Bay Area Air Quality Management District (BAAQMD) • BACT • 6.9 g/hphr Nox • .01(49) g/hphr particulates • Risk Asessment After treatment may be necessary

  7. How much fuel can I store? • 60-100,000 Gallons+ depending on your application • Very municipality oriented • Conflicts within municipality • Vaulted tanks are helpful • Sub-Base tanks must be UL142 listed and Dual Walled with various necessary options • Try to avoid underground storage tanks • Large sets can burn more than 100 gph

  8. How much does a system cost? • Diesel systems cost between $300-500/KW • Best suited for standby • Natural gas systems cost $400-800/KW • Best suited for cogeneration • Gas turbines $1000+/KW • Only feasible for large scale applications

  9. What is required to maintain my system? • Weekly checks • Physical check • Leak Check • Fluids check • Temperature check • Battery check • Weekly Test • Run to no load target temperature. Not necessary to test any longer than that • May be limited by BAAQMD • Quarterly or Yearly Load Test • Test records may be necessary
