Large Power – Coal Bed Methane

Coal bed methane members requiring 50 kVa or more of transformer capacity are charged under Large Power CBM rates. The rate is not applicable to CBM compression loads with individual motors of 1,000 or more horsepower.

The basic charge for secondary delivery is $100 per month and $135 per month for primary delivery. A demand charge of $3.00 per kilowatt hour is applied for the first 50 kilowatts and $7.00 per kilowatt for additional usage. An energy charge of $0.04920 for first 200 kWh per month, per kilowatt hour of billing demand with excess kWh at $0.02920.

A billing demand is derived and power factor adjustment is applied.

CBM members also provide funding for new CBM-related substations, transmission lines and system improvements through a $0.005 per kilowatt hour charge. Additional charges may be applied under PRECorp’s line extension policy.

Example: 50,000 kWh     100 kW

200 x 100 Kw = 20,000 kWh x 0.04920

50,000 – 20,000 = 30,000 at 0.02920
