Calculating the Financial Benefits of an Energy Efficiency Project: The Building Owner's and Invester's PerspectiveWatson, J. K. (Energy Systems Laboratory (http://esl.tamu.edu), May 1985)[more][less]
Abstract: In an era of high cost and heavy competition for capital, third-party financing of energy-related projects is a potentially attractive alternative to more conventional internal funding. To judge the applicability of outside funding to a particular project, facility owners and potential third party investors need to know how to evaluate the costs and benefits involved. The purpose of this paper is to present such an evaluation, using data taken from a real project.

Abstract: Conservation is the foundation of California's energy policy and the largest single source of the state's 'new energy supply'. Our goal is to use economic market forces and government programs to direct energy Investments away from our current dependence on oil. In making our investments, we have given energy efficiency the highest preference, followed by cogeneration and renewable energy supplies. Conventional power supplies come last, and only when absolutely necessary because they are costly, they pose environmental risks, and require long lead times. These priorities guide investment decisions by utilities, state and local governments, and the state's business community. Their combined efforts have cooled energy demand significantly, shattering the conventional wisdom that economic growth and energy demand are inextricably linked. While the Gross State Product has grown 35% faster than the national average in the past five years, there has been a 10% drop in natural gas use in California. Today, growth in electricity demand in the state has dropped to less than 1/3 the rate anticipated in 1974, eliminating the need for $60 billion in new plant expenditures by the strapped utility industry.

Abstract: This paper describes the California Energy Commission’s (Commission) energy policies and programs that save energy and money for California’s manufacturing and food processing industries to help retain businesses in-state and reduce greenhouse gases through decreased energy use. The Commission’s objective is to achieve 2 trillion British Thermal Units (Btu) per year in energy savings for California industry by the year 2010. These energy savings will come from implementation of projects that are a direct result of plant assessments conducted by the Commission, and from improved skills of industrial equipment operators attending United States Department of Energy (DOE)-funded industrial BestPractices workshops conducted by the Commission in partnership with industry and the state’s utilities. In addition to energy and cost savings for California’s industrial sector, this program will also reduce direct carbon dioxide emissions from industrial processes by over 110,500 tons each year.

Abstract: Increasing fuel costs have forced industry to look at ways to conserve energy. Preheating combustion air by utilizing the wasted heat in the flue gas can result in significant fuel savings. The attractiveness of the payback figures have prompted many companies to venture into heat recovery projects without due consideration of the many factors involved. Many of these efforts have rendered less desirable results than expected. Heat recovery in the form of recuperation should be considered as only one aspect of a total furnace system. Other factors, such as furnace design, burner turndown, furnace atmosphere, pressure control and the combustion system, will all interrelate to influence efficiency and the successfulness of the installation. National Forge Company has had considerable experience in high temperature heat recovery and the paper will discuss how these other design parameters must be considered to make the installation a success.

Abstract: A good energy accounting system can be a very helpful management tool, offering flexibility to respond quickly to those factors that impact energy usage. It also has the potential of providing an early warning about problems that could be very costly if they are not identified quickly. Also, an energy accounting system can be used as a budgeting tool and as a system to evaluate energy saving devices and services. One very important benefit of an effective energy accounting system is that it offers a method to justify energy costs to management and, possibly, some creative financing alternatives. It can also make it easier to monitor pilot projects to determine the overall benefit before they are implemented throughout the company. This paper briefly describes some of the issues that must be reviewed in developing an energy ccounting system. Also, it discusses some of the applications of an energy accounting system in justifying expenditures and troubleshooting energy usage variances.

Abstract: Industrial Energy Conservation in Canada is organized and promoted through a voluntary program that is administered by industry. Industry is divided into fifteen sectors, each of which is represented by a Voluntary Task Force. Information exchange, goal setting and progress reporting are carried on through these Task Forces which are staffed with industrial volunteers and representatives from the major trade associations. Inter-industry liaison is accomplished via a Coordinating Committee comprised of the individual Task Force Chairmen and representatives of the federal government. While the program has been in existence only since 1976, impressive gains have already been made and targets have been set for 1980 and 1985. The strength of the program lies in its candid cooperation between industry and government. There has, to date, been no need or advantage to implementing a government mandated program for industrial energy conservation in Canada.

Abstract: Industrial facilities universally struggle with escalating energy costs. EnerNOC will demonstrate how commercial, industrial, and institutional end-users can capitalize on their existing assets—at no cost and no risk. Demand response, the voluntary reduction of electric demand in response to grid instability, provides financial incentives to participating facilities that agree to conserve energy. With demand response, facilities also receive advance notice of potential blackouts and can proactively protect their equipment and machinery from sudden losses of power. A detailed case study, focusing on a sample industrial customer’s participation in demand response, will support the presentation.

Abstract: Energy Management and Reporting Systems (EMRS) have proven effective in reducing powerhouse cost. These cost reductions are provided through effective management of equipment operation, fuel allocation, combustion optimization, and generation management by a real time closed loop control system. A recent finding is that the application of consistent operating rules across all operating shifts increases reliability and the reduction of unscheduled outages. This paper presents an automated calculation methodology to identify and capture those savings.

Abstract: In this paper, we analyze and update our estimates of CHP's potential for U.S. manufacturers. Typical efficiencies of available CHP technologies are used to estimate their energy use and carbon emissions. In calculating the baseline against which CHP is compared, we take into account efficiency improvements in both the industrial sector and in the electricity-producing sector. We find that manufacturers save energy and reduce their carbon emissions substantially if they replace all retiring boilers stocks and new additions to the stock (from 1994 to 2010), with existing cost-effective CHP technologies. Carbon equivalent (=12/44 carbon dioxide) emissions would be reduced by up to 70 million metric tons of carbon (MtC) per year in 2010, (18%-30% manufacturer's projected emissions), and energy use reduced by up to 7 Exajoule (EJ). These estimates also take into account growth in manufacturing, as forecast by AEO-98, and expected improvements in CHP, boilers, and electric generating technologies. However, without policy innovation, actual CHP installed by U.S. manufacturers will likely fall far short of our estimates.

Abstract: Over the past century, fossil fuel consumption has added carbon dioxide to the atmosphere at rapidly increasing rates. The prospect of further acceleration of this rate by turning from petroleum to coal has alarmed climatologists because of possible catastrophic long term effects on world climate. An alternative to discharging carbon dioxide into the atmosphere is to find new uses. One possible use is in 'Biofactories'. Biofactories may be achieved by exploiting two new developing technologies: Solar (Photosynthesis) energy, and genetic engineering. Some exciting new developments in genetic engineering will be touched on together with established bio-engineering-aquaculture, hydroponics, yeast, pharmaceutical production, fermentation, single cell protein, etc. A 'bio-factory' will be described, with a feed stream of carbon dioxide, water, nutrients containing sulfur, nitrogen, phosphorus and trace elements, and living culture interacting with light under controlled conditions to yield food and raw materials. Candidate products will be suggested and a few of the problems anticipated. Engineering and logistic requirements will be outlined and the economic impact assessed.

Abstract: WOW Energies was issued Patent 6,857,268 B2 on Feb 22, 2005 titled “CASCADING CLOSED LOOP CYCLE (CCLC) and Patent 7,096,665 B2 on August 29, 2006 titled “CASCADING CLOSED LOOP CYCLE POWER GENERATION”. These patented technologies are collectively marketed as WOWGen®. The WOW Energies patents represent the production of efficient power from low, medium and high temperature heat generated from the combustion of fuels; heat from renewable energy sources such as solar and geothermal heat; or waste heat sources. Waste heat sources can be in the form of exhaust stack flue gases; waste heat from vented steam or steam discharged from steam turbines; hot water; hot oils or combined waste heat sources. A major advantage of the WOWGen® power plant is the ability to produce power without the use, consumption or contamination of valuable water resources. Production of power from waste heat and renewable energy sources is the most viable path to energy independence from foreign oil and reduced emissions from the combustion of fossil fuels. The WOWGen® power plant inherently reduces emissions and Greenhouse Gases (GHG) by producing power from waste heat without consuming fuel, thus increasing the overall energy efficiency of any industrial plant or power generation facility. The presentation will focus on the technology and provide case studies of its application.

Abstract: Bristol-Myers Squibb Worldwide Beauty Care Group has adopted a methodology that is reaping benefits throughout the company. The underlying principle in cascading goals and objectives is that every employee is accountable for achieving any corporate goals and objectives from the business level to the individual level. This cascading process encompasses the business unit, operations group, facility, and department levels. The institutionalization of goals and objectives is demonstrated by integrating goals that used to be associated with a specific area (e.g., energy, environment, health, or safety) with basic business metrics and thus ensuring action by everyone. Performance is monitored at every level and incentives exist at every level. The cascading methodology has been a paradigm shift and quite successful for the Worldwide Beauty Care Group, Worldwide Clairol, of the Bristol-Myers Squibb company.

Abstract: In 1977, TI purchased a 158,000 SF, single story building which was designed and built prior to the 1973 energy crises and, hence, has no built in energy conservation. This paper addresses the principal retrofit measures taken at this calculator & home computer assembly plant. They are: 1. A roof spray system; 2. Reduction of illumination levels and the use of more efficient luminaries; 3. Chilled water temperatures in the 52 F to 55 F range with condenser water temperatures near the cooling tower designed approach; 4. Installation of a programmed controller with signals sent over existing power lines to control times on and off of exhaust fans, lighting, DX A/C units, etc.; 5. Substitution of energy efficient electrical motors for the original motors where cost justified; 6. Reduction of the volume of air circulated and minimization of fresh air intake; 7. 'Free' cooling from the latent heat of evaporation of spray nozzles used to keep a high plant humidity; and S. Heating incoming water for PCB washers with the 150 F washer effluent. The implementation of these energy conservation measures resulted in a continuing lower KW demand and KW-hr usage during a four-year period when manufacturing levels were steadily increasing.

Abstract: In today' s equipment market more and more projects are turning toward existing equipment to justify a project. New equipment's delivery time and/or capital cost can keep a good project "grounded". In the turbomachinery industry, a few companies have developed the expertise to identify candidates of existing machines that can be adopted for many new applications. These companies can inspect, modify, recondition and rerate the equipment as needed, which helps bring in a project within budget and on time. This paper is the history of such an application. The delivery schedule requirements and limited capital made the project feasible only through the technology of reapplying existing machines to a new service. The project involves a plant that extracts landfill gas and converts it to diesel fuel, naphtha and a high grade of wax. The plant requires a steam turbine generator set to produce electrical power for its base load operation. This paper covers the history of how the turbine, gear and generator were selected, along with the highlights of the engineering work required to insure the mechanical operation of the string of equipment.

Abstract: Much has been written about the advantages and disadvantages of high efficiency electric motors. For a given motor application it is possible to find literature that enables a plant engineer to make an informed choice between a standard efficiency and a high efficiency motor; however, few plant engineers have the time to perform a detailed analysis for each motor in their facility. A technique is needed to reduce the analysis to manageable proportions. This paper looks at efforts to identify high efficiency electric motor applications at two manufacturing facilities. It describes a technique that was used to assemble available data in a form that helped prioritize motors in terms of suitability for retrofit with high efficiency models. The technique addresses the problems of limited time and missing data, and suggests ways for quickly filling in data gaps. The motors in the studies spanned a range of 7.5 to 250 hp. The prioritization was performed primarily on the basis of simple payback. The study results are of potential interest to persons interested in the overall applicability of high efficiency motors in manufacturing.

Abstract: This paper describes the results of a survey and evaluation of plant-specific information on industrial cogeneration. The study was performed as part of a project sponsored by the Electric Power Research Institute to evaluate Dual Energy Use Systems (DEUS). The purpose of this project was to evaluate site specific data on DEUS from the utility perspective, identify promising candidates, and define R&D opportunities. The first major task in this DEUS project was a survey of industrial cogeneration sites to identify the technoeconomic and institutional factors affecting the success of cogeneration systems in industry. Sites were selected based on a mix of industry types, geographic location, type of cogeneration system, generating capacity, age of plant and other characteristics. Site-specific surveys were conducted and supplemented by information from secondary sources such as FERC and DOE statistical data systems. This paper presents information on 17 cogeneration facilities. Also presented is information on the perspectives of the relevant utilities.
