Project DescriptionFinancial Energy installed: 1) demand controlling equipment; and 2) sub-meters in the electrical room of this retail/warehouse complex. The owner receives one utility bill for all tenant spaces from Xcel. The objective was to: 1) properly allocate electric costs by tenant; and 2) reduce the peak electric demand costs which are 60%-65% of the electric bill. Financial Energy installed a demand controller to limit the coincident operation of the complex’s 21 RTU’s and electric water heaters. The demand limiting system monitors the building’s electric demand (kW) and automatically limits the peak demand use at the facility by cycling the RTU’s to limit coincident use. By controlling this equipment, Financial Energy is able to reduce the complex’s peak demand by about 20%. The controller is connected to a modem, allowing remote control of the demand limiting system via computer (with corresponding software) located at the property owner’s office building. This retail and warehouse complex had existing electric sub-meters installed, but the meters only measured kWh consumption not kW demand. Some tenants had multiple sub-meters and the meters had to be manually read each month. Financial Energy installed a new sub-metering system which records both kW and kWh use and billing software which produces a bill for each tenant every month. The sub-meters are connected to a modem allowing the property owner to automatically download the consumption data eliminating the need to have personnel drive to the site and manually read the sub-meters. The metering software automatically apportions the utility bill charges to each tenant, significantly simplifying the billing process. |
