Powerful Terms Amp = the number of electrons moving along a conductor path Voltage = the force at which energy flows Watt = one AMP at a pressure of one VOLT (Watts = Volts X Amps) Kilowatt (kw) = 1,000 Watts Megawatt (MW) = 1,000,000 Watts =1,000 kw

Powerful Terms Demand = rate of energy consumption Kilowatt Hour = quantity of energy Load Factor = relationship between quantity and maximum rate of energy used Power Factor = ratio of true power to total power

What Information is Needed? BASIC (minimum) Peak Demand Energy Consumption Hours of Operation Delivery Voltage MORE REFINED (detail) Load Characteristics Type of Equipment Employed Power Quality Requirements Power Factor

Why We Need It? General (minimum) In-Service Date Determine Available Capacity Measure Impact on System Picture Demands on system Planning for Growth Detailed (great to have) Upstream Impact Downstream Impact Anticipate System Demands MOST OF ALL TIME!!

NATURAL GAS TERMS BTU (British Thermal Unit) = Heat needed to raise 1 lb. of water 1 F under constant pressure Volume = Basic unit is cubic feet or therms Pressure = Basic unit is PSIG (Pounds/inch²) or PSIG (Pounds/inch²Gauge) Demand (Load) = rate of gas consumption

NATURAL GAS TERMS 1 cubic foot (cf) = 1,027 Btu 100 cubic feet (1 ccf) = 1 Therm (approximate) 1,000 cubic feet (1 Mcf) = 1,027,000 Btu (1 MMBtu) 1,000 cubic feet (1Mcf) = 1 Dekatherm (10 therms) 1 million (1,000,000) cubic feet (1Mmcf) = 1,027,000,000 Btu 1 billion (1,000,000,000) cubic feet (1Bcf) = 1.027 trillion Btu
