Compressed Air Best Practices - February 2009 - (Page 30) | 02/09 Focus Industry POWER PLANTS | Project #2: Demand Control BY THOMAS MORT, CEM Overview Reducing energy costs and pollution emissions involves many areas within an industrial facility. My studies have found seven key (or common) areas where low-cost, practical projects can be implemented. Combined, these projects provide savings exceeding 10% of the annual energy spend with an average payback of less than one year. This month’s article will focus on Demand Control. Electricity for most industrial facilities has two or more costs. First there is the energy cost which is measured as kilowatt hours (kWh), and then there is the demand cost measured as kilowatts (kW). Understanding the costs of these two units and also how the time of use is related is an important part of managing your energy costs. The utility term for this is Tariff Rate Schedule. Demand Control Project Objectives We can describe our demand control project as an effort to reduce the cost of energy by minimizing the use of electricity during the peak demand periods. Symptoms that can help identify the opportunity for a demand control project include: 1. 2. 3. 4. The tariff schedule shows a demand charge and energy charge The facility has equipment loads that operate less than 24 hours per day The electric load profile shows demand peaks There are equipment loads which can be interrupted for a period of greater than 15 minutes kW CO2 O Seven Key Sustainability Projects 1. Lighting 2. Demand Control 3. HVAC 4. Compressed Air 5. Metering 6. Heat Recovery 7. Project Implementation and Funding 30 www.airbestpractices.com http://www.airbestpractices.com
