Electricity Rate Cases
3
– Low Electricity Rate Case (High Energy Demand)• Low natural gas and carbon prices • More sales to recover transmission and distribution and
other relatively fixed costs
– High Electricity Rate Case (Low Energy Demand)• High natural gas and carbon prices • Lower demand means fixed costs per kwh of sales are
higher
– Mid Electricity Rate Case (Mid Energy Demand) • Mid demand, natural gas, and carbon prices
