Emergency and Standby Power

Hurricane Sandy reinforced the critical nature of the supply of power to critical facilities. Entities such as municipal offices, sewage treatment and water supply facilities, gas stations and supermarkets all rely on power to function. The loss of utility power without a reliable backup generator system can cause normally available services to be lost for extended periods of time.

Experience & People

D&B’s extensive design and construction management experience with emergency and standby power systems includes the design of generator systems ranging in capacity from 15kw to 1.5MW.

In addition to our Electrical Engineering staff, D&B has mechanical, structural and civil engineers experienced with fuel storage and pumping systems, concrete foundations and site work. D&B also routinely prepares generator set submittal drawings for Fire Marshal review and approval.


D&B understands that each generator installation is unique and requires comprehensive evaluation of:

  • Generator set kw & alternator requirements
  • Generator set location, which includes facilitating installation with respect to integration with the existing electrical system
  • Generator set elevation with respect to flooding potential
  • Fuel type – diesel, natural gas, liquid propane, dual fuel
  • Fuel tank alternatives for diesel generators – above grade, below grade or sub-base
  • Fuel tank capacity
  • Outdoor generators: Enclosure type, including sound attenuation

During the design phase, D&B also provides:

  • Natural gas generators: Utility coordination for gas service, including pressure requirements
  • Diesel generators: Fuel leakage and level monitoring systems
  • Automatic transfer switch & electrical distribution design to integrate the generator into the existing electrical system
  • Permitting
  • Preparation of Fire Marshal submittal drawings
  • Construction cost estimate

Construction management services provided by D&B for generator set installations include the following:

  • Review of shop drawing submittals
  • Construction inspection
  • Shop witness testing of generators
  • On-site load bank testing
  • O&M manual review
  • Automatic transfer switch setup
