Price Point Determination for Fuel Switching

Answer 7

Point of Use

Question 8

This charge covers the utility’s fuel cost and their operating and maintenance costs

Answer 8

Energy Charge

Question 9

This charge is based on peak power used by the customer in the month

Answer 9

Demand Charge

Question 10

For high spike in demand Billed, the price does this and stays that way for a certain amount of months. varies from 50-100%

Answer 10

Demand Ratchet Clause

Question 11

= actual demand * (o.8/PF)

Collection of inefficiency

Answer 11

Power Factor Adjustment/ Power Factor Adjusted Demand

Question 12

This factor means that electrical capacity is not being used very effectively.

Answer 12

Low power factor

Question 13

= Minimum power factor required by the utility

measured power factor during that month

Answer 13

Billed demand

Question 14

Utilities use __ __ __ to compensate for the variance in fuel costs

Answer 14

Fuel adjustment charges

Question 15

This is an additional cost if you get your power from facilities that are located in areas that allow for choice of generatiom. You are paying for the last mile infrastructure

Answer 15

Generation Costs

Question 16

recovery of payments made by the utility for capaicty, net of revenues received by the utility for capacity sales

Answer 16

Capacity Costs

Question 17

How to calculate an electrical bill?

Answer 17

1. Calculate the demand charge and if you have ratchet you will have to use whatever kW is highest
2. calculate the generation costs (kWh - distribution and generation)
3. Add customer charges
4. Add those together and add tax rate

Question 18

This charge is for facilities who receive electric power at approximately 13.8kV vs smaller facilities receive a voltage level of approximately 480 volts

Answer 18

Primary vs secondary voltage charges

2-3% reduction in monthly charges if you take a primary volts

Question 19

amount over and under a contracted amount of kWh/Therm usage a customer can use before another pricing mechanism is employed

Answer 19

Bandwidth

Question 20

Costs that show up on your gas/electric bill that were not locked down the day you sign the contract. These charges may include capacity charges, renewable energy charges, etc.

Answer 20

Pass Thru

Question 21

Contract terms and conditions automatically renew

Answer 21

Evergreen Clause

Question 22

provides an opportunity for consumers to play a significant role in the reliability and operation of the electric grid by reducing usage during peak periods to time-based rates

Answer 22

Demand Response

Question 23

The basic measure of a facility’s energy performance and provides the statement of the number of Btu’s of energy used annually per square foot of conditioned space. kBtu/year/ft^2

Answer 23

Energy Use Index

Question 24

The basic measure of a facility’s energy costs and provides the statement of the number dollar paid annually for energy sources per square foot of conditioned space. $/ft^2 per year

Answer 24

Energy Cost Index
