3 Business Energy Efficiency Customer s View Roy M. Palk, Esq. August 29, 2012
4 Presentation Segments 1. Overview of Business Energy Use 2. Retail Billing Components 3. Usage Management Techniques 4. Renewable Energy Credits (RECs) 5. Energy Efficiency Standards 6. Net Metering 7. Monitoring and Verifying Results 8. Summary
5 Overview of Business Energy Use Manufacturing Industry Sector Examples (By NAICS Codes) Energy Intensive Manufacturing: Metals, Paper, Chemicals, Petroleum Non-Intensive Manufacturing: Electronics, components, appliances Balance of Manufacturing Sectors: Apparel, Printing, Wood products, Misc. Mfg.
6 Key Terms Related to C&I Energy Consumption Energy Intensity - the quantity of energy required per unit output or activity, so that using less energy to produce a product reduces the intensity Energy Efficiency - improves when a given level of service is provided with reduced amounts of energy inputs or services are enhanced for a given amount of energy input
7 Retail Billing Components 1. Demand total amount of power consumed within a given time frame, e.g. 15 minutes (related to capacity investment) 2. Energy KWH consumed 3. Facilities Charge May be related to dedicated facilities invested by the utility to serve a particular load
8 Retail Billing Components - Continued 4.Minimum Bill a monthly amount billed to the customer to cover the fixed costs of the utility such as when a location is not in production 5. Other Charges Taxes, Environmental Surcharges, Fuel Adjustment Charges, etc.
9 Usage Management Techniques 1. Practices depend on the type and schedule of production 2. Staging to control the demand (see time interval reference above) 3. Power Factor Correction (capacitors and PF corrected motors) 4. Waste heat recovery, self generation 5. Renegotiating Power Contracts to fit changed production schedules
10 Research Incentives 1. Federal and State Tax Incentives cfm 2. Renewable energy credits (create and sell of purchase to offset emissions) 3. Net Metering
11 Energy Efficiency Standards 1. Check state, federal and industry standards/requirements for new equipment installations ASHRAE 90.1 for commercial heating and air conditioning 2. The Energy Policy and Conservation Act (EPCA) established Federal energy conservation standards for commercial heating, air conditioning, and water heater equipment (in re to number 1 above)
12 Monitoring and Verifying Results 1. Performance Contracting split benefit approach 2. Identifying particularly large users of energy with in a facility and installing controls 3. Virtually real-time dashboard monitoring 4. Controlling energy demand against the utility s tariff, TOU demand and energy tariffs
13 Summary 1. Energy intensity is lessening while energy efficiency is increasing due to a slower economy and better equipment. (EIA) 2. A shift in new power generation, resulting in higher power costs, will place more emphasis on energy efficiency.
