What is EMIS?
Electrical watt-hour or similar submeters have long been available as a means for the facility owner/operator to measure energy usage within their facility. Under regulated tariff structures, the information obtained from a submeter may not, however, be used to bill for electricity. Information from the meter was typically manually read directly from the meter face. The use of microprocessor-driven meters that utilize data capture and storage has also been available, but due principally to reasons of cost, have been limited to heavy industrial use where the quantity of energy metered, relative to the per-point cost, has been acceptable. For the smaller facility, the cost of such systems has been out of reach. The advent of powerful, but low cost, digital meters coupled with low cost database and software platforms connected within the facility through optical, hardwire or wireless means, and between facilities through hardwire, wireless or Internet is the basis of present-generation EM
