JStudebaker 4/23/ How Electricity & Natural Gas Originate & Flow Electricity Generation of electricity Interstate transmission grid Intrastate Distribution grid Natural Gas Natural gas wells Interstate transportation pipeline Intrastate Transportation Pipeline CUSTOMER USE METER POINT CUSTOMER USE METER POINT JStudebaker 4/23/

3 REGULATION IN GENERAL 1. All utilities (electricity & natural gas) are generally regulated monopolies. 2. A 'regulated monopoly' means that it - Has no regulated competition Has all customers in a protected service territory 3. Utilities are regulated in two areas - Intrastate - within a state Interstate - between states JStudebaker 4/23/ INTRASTATE REGULATION (Within the State) Intrastate regulation for electricity and natural gas utilities includes - 1. For-Profit Utilities (In business to make a profit) 2. Municipal Utilities (Are not allowed to make a profit) 3. Cooperative Utilities (Are not allowed to make a profit) JStudebaker 4/23/ WHERE DO MUNICIPAL & COOPERATIVE UTILTIES GET THE ENERGY THEY SELL? JStudebaker 4/23/

4 In general, they purchase wholesale from for-profit utilities. For-Profit Utility (electricity & natural gas) Retail Customers And users in their service territory Wholesale Customers Municipal & Cooperative Utilities Some Municipal & Cooperative utilities do generate their own energy. JStudebaker 4/23/ FOR-PROFIT UTILITIES 1. Regulated on a statewide basis by a commission or individuals appointed/elected at the state level. 2. Utilities in business for making a profit are generally owned by shareholder investors. 3. For-Profit utility regulation process: a) Public notification of intent to change/revise rates or procedures. b) Adequate notification period, generally several months notice. c) Allow input from interested customer groups (customers include actual energy users of that utility or their representatives). JStudebaker 4/23/ MUNICIPAL UTILITIES 1. Owned/operated by a city or county and generally self-regulated/self-governed. 2. Are generally presided over by a commission, or appointed or elected board members. 3. Municipal utility regulation process: a) Public notification b) Adequate notification period c) Presentation of rate request d) Allow input from interested customer groups JStudebaker 4/23/

5 COOPERATIVE UTILITIES 1. Usually serve rural areas where there may not be a large customer load base and are selfregulated. 2. Power generally is purchased wholesale from a For-Profit utility with the Cooperative utility being owned and operated by the customers it serves. 3. Cooperative utility regulation process: a) Public notification b) Adequate notification c) Presentation of rate request d) Allow input from customers JStudebaker 4/23/ The Interstate Regulation Process (between individual states) 1. The state agencies involved regulate distribution and provide the day-to-day regulatory functions of electricity & natural gas within their particular state. 2. The portion of the transaction outside of a given state s boundary is regulated by federal regulatory agencies. 3. Utilities typically use a combination of interstate (within a state) and intrastate (between states) components, and both state and federal regulation. JStudebaker 4/23/ The Intrastate Regulation Process (within the state) WHO IS RESPONSIBLE? 1. The Federal Energy Regulatory Commission (FERC) is responsible. 2. FERC regulates electricity and natural gas distribution from one state to/for another state across individual state boundaries. 3. FERC is composed of members appointed by the President. 4. FERC can be contacted at: JStudebaker 4/23/

6 FERC Responsibilities 1. Certifies small FERC power production. 2. Certifies cogeneration facilities. 3. Approves/enforces rates & charges for sale & distribution of electricity/natural gas between states. 4. Establishes & enforces oil pipeline rates, charges, and valuations. 5. Hears Dept. of Energy appeals of remedial orders and/or denials of adjustments. JStudebaker 4/23/ Steps To Reducing Electricity Costs JStudebaker 4/23/ Energy (electricity) Data Needed Energy Provider (the utility) OBTAIN Complete Tariff Schedule Individual Rate Schedule Data State Website OBTAIN Experimental Rate Tariffs Off-Tariff Schedule Data JStudebaker 4/23/

7 How to Understand Electricity Utility Billing Information? JStudebaker 4/23/ Know Electricity Areas to Evaluate 1. Rate (tariff designation) 2. Demand (capacity reservation needs) 3. Power Factor (efficiency of electricity usage) 4. Voltage Level (where does the utility deliver the electricity to the customer) 5. Usage (the actual energy that is consumed by a customer on a monthly basis) JStudebaker 4/23/ RATE Utility customer usage characteristics Classification including: 1. Applicable rate tariff 2. KW (demand) 3. Power factor 4. Voltage level 5. KWh (usage) JStudebaker 4/23/

8 Sample Electric Utility Monthly Billing - RATE GS-GENERAL SERVICE JStudebaker 4/23/ RATE Components of Sample Electric Utility Monthly Billing Rate Savings Potential Up to 30% What to do? GS - General Service Check for alternative rates for customers with your usage characteristics REMEMBER The Customer is always responsible for the most cost-effective applicable rate! JStudebaker 4/23/ Rate Evaluation Process 1. Look for applicable alternative rates Obtain complete electricity tariff schedule 2. Determine cost reduction potentials: Check demand levels Usage levels Hours & days worked Future facility changes or revisions 3. Evaluate applicable alternative rates for "best fit" JStudebaker 4/23/

9 2. DEMAND The peak amount of electricity/natural gas consumed in a measured interval (15/30 minute or other period). This is called Capacity Reservation Cost It has nothing to do with actual monthly consumption of energy or work accomplished. JStudebaker 4/23/ Sample Electric Utility Monthly Billing Demand (KW) DEMAND CHARGE 250 $ = $2, Total Peak Penalty 83 kw (250 kw kw) TOTAL KW 167 JStudebaker 4/23/ DEMAND Components of Sample Electric Utility Monthly Billing On this sample billing 250 kw Savings Potential 5% - 20% Measured in kw 1 kw = 1,000 Watts Definition Capacity Reservation Charge JStudebaker 4/23/

10 Electricity Demand - Cost Components Demand - "Is the rate at which electric energy is delivered to or by a system, part of a system, or a piece of equipment expressed in kilowatts (kw), kilovolt-amperes (kva), or other suitable unit at a given instant or average over a designated period of time. The primary source of demand is the customer s power-consuming equipment measured in 15/30 minute intervals. Demand charge can vary from less than $ $30.00 or more per kilowatt per month. Reduction of demand peaks can result in sizeable savings. Demand reduction does not necessarily mean reducing total demand utilized, but it can mean changing when certain pieces of equipment operate. JStudebaker 4/23/ HOW DOES DEMAND OCCUR? Demand (kva/kw) occurs as a result of multiple electrical consuming items operating during the same 15/30 minute time interval. In the following example, the customer would pay for 991 kva/kw. (assuming no other tariff provisions applied) ITEM kva/kw average over 15/30 minute period 1. Motor Motor Motor Motor Motor Lighting Lighting Lighting HVAC HVAC Office Miscellaneous 87 TOTAL 991 kva/kw JStudebaker 4/23/ Strip Chart Example of Electricity Peaks JStudebaker 4/23/

11 Steps that can assist in determining and correcting Electricity Peak Demands 1. Determine - Current peak demand and related monthly charges. 2. Contact - Utility and request the installation of a strip chart recorder in the system for at least a one-month period. 3. Analyze - Strip chart to determine if there are repetitive peak patterns: hour-to-hour, day-to-day, week-to-week. 4. Develop - Corrective actions needed to be made to correct peak demands. JStudebaker 4/23/ Demand Evaluation Process 1. Utilize utility strip chart data to determine when/where peaks occur. 2. Analyze strip chart information. 3. Take corrective action based upon utility strip chart data. JStudebaker 4/23/ POWER FACTOR 1. Power Factor is the efficiency at which electricity is consumed. (kva/kw) 2. It is the relationship between Demand (kva/kw) and Usage (kwh). 3. The higher the Demand (kw), the higher the overall cost per kwh. 4. The lower the Demand (kw), the lower the overall cost per kwh. 5. Savings potential: 5% - 15% THE CUSTOMER CONTROLS KVA/kW and kwh relationship items. The cost of the electricity they consume. JStudebaker 4/23/

12 Sample Electric Utility Monthly Billing - Power Factor Power Factor 60% (167 kw 278 kva) Actual billing Demand 90% (250 kw 278 kva) DEMAND CHARGE 250 $ = $2, TOTAL KW 167 TOTAL KVA 278 JStudebaker 4/23/ Power Factor Cost for this Example Power Factor sample billing cost: 250 kw Billed (90% x 278 kva) 167 kw Actual 83 kw Penalty (83 kw x $ per kw = $ penalty) OR 16% OF TOTAL COST JStudebaker 4/23/ Power Factor Calculation Details Utility provided peak kva Customer utilized peak demand in kw 278 kva 167 kw Power factor in this example would be: 60% (167 kw 278 kva = 60%) JStudebaker 4/23/

13 Power Factor Evaluation Process 1. Determine Power Factor cost 2. Consider correction capacitors 3. Calculate cost vs. savings 4. Make decision based upon cost / savings rationale JStudebaker 4/23/ VOLTAGE LEVEL 1. Voltage level is determined by the location of the billing meter point in the electrical distribution system from the utility to the customer. 2. Generally the lower the meter point voltage level, the more expensive is the incremental usage (kwh) cost to the customer. 3. Savings potential: 1% - 3% Typical Voltage Levels Secondary volts or less Primary - over 440 volts JStudebaker 4/23/ Sample Electric Utility Monthly Billing - Voltage Level SECONDARY VOLTAGE 220 VOLTS JStudebaker 4/23/

14 Increasing Voltage Level Evaluation Process Utility s transmission lines Most customer s end use 128,000; 69,000; 4,100 volts 440, 220, 110 volts What to do if a customer is served at Secondary Voltage level and if tariff schedule provides for Primary Voltage discounts? 1. Have utility company calculate annual savings of switching from Secondary to Primary Voltage levels. 2. The most economical method to convert to Primary Voltage - a) Determine savings potential b) Consider transformer lease c) Consider transformer purchase d) Calculate savings opportunity JStudebaker 4/23/ ELECTRICITY USAGE (kwh) 1. In an electricity monthly billing, the only item that provides value for the customer is the Usage (kwh) utilized. 2. All other components - Demand, Power Factor, Voltage Level, etc. - while required, do not in themselves provide any actual Usage benefits. 3. Usage is probably one of the most difficult items to reduce but its reduction will provide probably the most ongoing value of any single billing component. 4. Savings potential: 3% - 10% Usage (kwh) = Connected load X hours of use (1) kwh = (1,000) Watts for (1) hour JStudebaker 4/23/ Sample Electric Utility Monthly Billing - Usage (kwh) ENERGY CHARGE $ = $2, (Including Fuel Cost Adjustment) TOTAL KWH JStudebaker 4/23/

15 Usage - Sample Billing Analysis $2, kwh Charge = 50.7% of total electric cost: $4, Where is the other 49.3% Customer Charge $21.64 Demand Charge $2, Total $2, USAGE CHARGE $2, % 50.7% JStudebaker 4/23/ USAGE EVALUATION PROCESS 1. Analyze facility to determine kwh reduction potential 2. Consider energy-efficient equipment 3. Evaluate - a) Project design criteria b) Heating system efficiencies c) Motor size & efficiency d) Electronic ballasts e) Occupancy sensors JStudebaker 4/23/ Steps To Reducing Natural Gas Costs JStudebaker 4/23/

16 Billing Data Needed 1. Utility name 2. Account number 3. Facility address 4. Billing period 5. Rate 6. Gas units used 7. If transportation a) bank status b) actual usage 8. Actual billings JStudebaker 4/23/ Potential Cost Reduction Items 1. Rate appropriateness 2. Type of service 3. Usage variables JStudebaker 4/23/ Starting Points to Reduce Natural Gas Costs 1. Analyze billing history 2. Evaluate usage patterns 3. Identify large variables JStudebaker 4/23/

17 Natural Gas Categories Firm Service If any natural gas is available other than for a few exceptions, the customer will receive their needs. Natural gas purchased from a local distribution company (LDC) and has highest priority of delivery. Firm service is most expensive. Interruptible Service The customer pays less for this class of natural gas service but may have their supply curtailed. Natural gas is provided to customers who can accommodate service interruption on short notice - generally in peak-load seasons or situations. Interruptible service is less expensive. JStudebaker 4/23/ FIRM Tariff Natural Gas "Firm Tariff Natural Gas" - refers to natural gas normally purchased from the Local Distribution Company (LDC) - gas utility. "Tariff" - refers to a published volume of rate schedules, general terms and conditions under which product or service will be supplies. JStudebaker 4/23/ Facts About Firm & Interruptible Natural Gas FIRM SERVICE is not 100% non-interruptible INTERRUPTIBLE SERVICE may not be 100% interruptible. JStudebaker 4/23/

18 Natural Gas Interruption History 1. How many 2. How long 3. When 4. Where 5. Future JStudebaker 4/23/ Items to Consider - Natural Gas Interruptible Service Combine Firm and Interruptible services Onsite backup JStudebaker 4/23/ Natural Gas Usage Varies by - Hour Day Week Month JStudebaker 4/23/

19 Controlling Natural Gas Costs $ $ $ 1. Monitor actual usage 2. Determine reasons for variations 3. Minimize variations JStudebaker 4/23/ The Utility Commodity Deregulation Process JStudebaker 4/23/ What is "Utility Deregulation"? 1. Utilities involved - Electricity Natural Gas What part of the tariff rate is affected? COMMODITY ONLY (Usage) JStudebaker 4/23/

20 How Deregulation Works 1. Changes the commodity portion of the utility bill to a non-utility provider. 2. Requires the customer to arrange for commodity purchases. DEREGULATION DOES NOT ASSURE The lowest energy cost The most efficient energy use JStudebaker 4/23/ Commodity Information 1. Commodity cost is generally 50-70% of total utility bill. 2. Commodity purchases from non-utility providers will not guarantee reduced utility costs. JStudebaker 4/23/ Non-Utility Supplied Electricity & Natural Gas The Process JStudebaker 4/23/

21 Non-Utility Supplied Electricity & Natural Gas Information With the advent of energy deregulation, the opportunity for customers to purchase directly from a third party with the local utility delivering the energy to their facilities has become a reality. Who Sells This Energy? 1. Brokers 2. Marketers 3. Producers JStudebaker 4/23/ Electricity & Natural Gas Brokers 1. Most market-supplied energy is not sold by producers but by parties known as "Brokers". (aka Marketers) 2. Brokers do not take or assume title to the energy that they market. JStudebaker 4/23/ Electricity & Natural Gas Marketers 1. Marketers differ from Brokers in that they do take title to the energy they sell to the customer. 2. A marketer takes title to the energy but generally does not have or own production resources. JStudebaker 4/23/

22 Electricity & Natural Gas Producers 1. Producers have title to and also own production resources. 2. Producers are the original owners of the energy and are responsible for getting the energy to the electricity transmission grid or the natural gas distribution pipeline. JStudebaker 4/23/ Differences Between Electricity & Natural Gas Suppliers BROKERS Do not have title to or own energy production resources. MARKETERS Have title to but do not own energy production resources. PRODUCERS Have title to and own energy production resources. JStudebaker 4/23/ Deregulation in Michigan??? JStudebaker 4/23/

JStudebaker 4/23/ What is the Future of Energy Costs? 1. Higher costs overall. 2. More rate categories. 3. More frequent rate changes. 4. More interruptible energy. 5. Less firm energy. 6. More user involvement in energy cost pricing and usage factors. JStudebaker 4/23/

27 Energy Availability Now and in the Future JStudebaker 4/23/ IS ENERGY AVAILABILE NOW? YES! For All Customer Classes Residential Commercial Industrial Customers JStudebaker 4/23/ WILL ENERGY BE AVAILABILE IN 2-5 YEARS? YES - generally At Increased Cost for all Customer Classes Residential Commercial Industrial Customers JStudebaker 4/23/

28 WILL ENERGY BE AVAILABILE IN 5 YEARS +? YES - probably For All Customer Classes - BUT Firm - generally only residential customers Non-Firm - commercial & industrial customers JStudebaker 4/23/ Think about these questions: 1. How does alternative energy impact what has been discussed? 2. What is the standard unit of measurement for all forms of energy? 3. Do you think there will be more or less utility deregulation in the future? JStudebaker 4/23/ Thank you for your attendance!
