Start Realizing Untapped nest egg Opportunities and Tame Volatile Energy cost Traditional Energy commission Approaches ar Falling Short How to coiffure the Problem Energy utility costsprimarily natural bollix and electricityaccount for one to two per centum of sales for the second-rate business, and quite a little be as much as four to quint portion of cost of goods s mature for manufacturers. With dynamism prices turning volatile, corporate cargon teams are exposed to the risk of unanticipated movements in naught costs. They are feeling relatively helpless because of the perceived inability to proactively manage regulate nil costs. At the same time, firms are publicly committing to sustainability goals and are in a flash wondering how they will achieve them. Although many firms have implemented short-run measures to address goose egg costs and sustainability commitments, these efforts are falling short. Our benchmark info and research indicates that for or so firms, 50 percent of their sign pushing nest egg disappear within the basic six to 12 months repayable to a lack of continuous supervise, synopsis and corrective action. However, signifi stooget fortune to extradite value remains.Analysis from the U.S. Department of Energy indicates firms that embrace continuous monitor and active animation management practices can achieve 15 to 40 percent nada savings. Conduct an energy audit To establish an energy use baselinea basic requirement for successful energy cost optimization firms deploy monitoring devices to measure energy work from the facility level raft to the machine level. Implement audit recommendations aft(prenominal) appraiseing energy pulmonary tuberculosis levels and trends down to the machine level, managers can implement abut changes to optimize energy habit.Actions may range from policy formulation (shutting down computers at night, turning rack up undue equipment, etc.) to automation (automatically turning off lights) to equipment optimization (ever-changing set-points on heavy machinery and equipment). Invest in high-efficiency equipment With a rise view of the energy consumption and equipment efficiency profile of the enterprise, firms can strategically invest in high-efficiency equipment. These capital upgrades can lower energy consumption and may also qualify for rebates and incentives that can significantly enhance emf return on investment funds (ROI). Figure 1 This paper looks at why traditional nestes are failing, and outlines an active energy management approach that changes the game and generates sustainable energy cost reductions.Typical MonitoringSavings Typical energy management strategiesand why they fail to deliver sustainable value. For example, when firms conduct energy audits, employees and equipment operators are aware that their energy usage is macrocosm monitored and they make chan ges to reduce consumption, such as turning off idle equipment. But when monitors are removed, initial savings peak and then belatedly erode as employee behavior returns to normal. Similarly, when firms implement process changes, unquestionable initial savings accrue. However, when the monitors come off, gains decline as equipment schedules change.Operators go back to the old way of doing things and set-points revert to old levels. In addition, without detailed machine-level consumption info as a baseline (as opposed to a point-in-time snapshot), analysts are ineffectual to come up with truly optimal process betterments because the data is not granular enough. Finally, with capital equipment upgrades, savings targets are seldom realized due to unrealistic operating assumptions used to build ROI cases and most firms lack of securities industry intelligence about the complex array of incentives and rebates. 50% Savings A review of more than 100 companies and their practices reveal that most firms take third common actions to address the energy management challenge Although these traditional energy management techniques can yield quick-hit results, there is a common stone pit when the meters come off, it is back to business as usual and the savings disappear. 50 percent of initial energy savings disappear within the first six to 12 months due to a lack of continuous monitoring, analysis and corrective actionMonths from start 2 A four-step combat-ready Energy Management approach Recognizing where most initiatives fall short, an integrated, four-part Active Energy Management strategy can stop the bleeding and address traditional energy management shortcomings There are several keys to making energy savings persistent. First, take monitoring and measuring from a one-time analysis to an ongoing, active competency. leading(p) firms use 247 advanced metering and monitoring technology with practiced analysts to proactively monitor energy consumption data and p atterns. Continuous monitoring helps rationalize the savings escape cock described earlier. Active monitoring allows managers to seein near realtimeif employee behavior is beginning to change or old habits are starting to return, and identify the root causes when actual energy consumption differs from projections. In addition to preventing savings leakage, active monitoring helps identify new, incremental energy savings opportunities, raising the cumulative savings realized. Copyright 2014 Accenture All rights reserved.Go deeper Use machine-level consumption data to drive sustainable process optimization. With a detailed instinct of energy consumption down to the individual equipment level, managers can implement detailed process optimization programs, such as changing set-points for heavy machinery. For example, an air compressor energy consumption study (see figure 2) revealed an opportunity to adjust the operating mode from continuous to throttled, resulting in 7 percent ener gy savings verified by ongoing measurement. In an early(a)wise(prenominal) example, adjusting improper temperature set-points in a chiller plant establish on thorough analysis of usage data resulted in 30 percent energy savings. With the right intelligence and detailed monitoring, energy analysts can assess performance and immediately stop energy savings leakage. Analysts also can spot potential maintenance issues and proactively investigate when machinelevel performance deviates from expectations.Figure 2 250 Baseline Model Target Model Baseline Data factual Data 200 Air Compressor (kw) Get persistent Apply Active Energy Management and take monitoring from a onetime occupation to an active, ongoing analytical competency. 150 100 50 0 0 20 40 60 80 Air Demand (SCFM) based on Actual Production 100 3 Leverage cleverness Use energy petition appreciation to enhance capital investment decisions and capture incentives and rebates to drive higher ROI. A comprehensive understanding of the consumption profile of the existing asset base enables much better capital investment decisions. Armed with detailed data and realistic energy consumption estimates, managers can rationally weigh the benefits of energy-efficient new equipment versus their purchase costs and other related expenses (decommissioning and disposal cost, production downtime, etc.). Beyond energy data, deep commercialise intelligence of credits, incentives, and local, state and federal rebates can dramatically alter the ROI profile of new capital investments.The opportunities are substantial In 2011 alone, governments, nongovernmental organizations and utilities distributed more than $6.8 million in cash payments to promote energy efficiency initiatives. Tackle the provision side Extend Active Energy Management to integrated energy supply and demand management to drive the next level of savings. As this paper describes, current energy management practices are not delivering on their promises. The sh ort-term benefits of energy audits and near-term recommendations quickly fade without continuous monitoring. On the other hand, Active Energy Management, which includes continuous monitoring and analysis, prevents the traditional savings leakage seen in most energy management programs. It also provides the data and insight that analysts and managers need to identify new savings opportunities and drive continuous improvement and cumulative energy savings benefits. With an established platform of ongoing measurement and management, firms can take energy savings to the next level.Detailed understanding of historical and planned consumption allows for acceleration of supply side strategies. For example, in de correct markets, the accuracy with which a firm can predict its energy usage determines its ability to secure favorable energy rates by minimizing bandwidth charges. Energy consumers can also capture other savings through techniques wish well load shifting (shifting usage into low er-rate time periods) and peak shaving. Finally, in regulated markets, contrary to popular belief, firms can optimize their energy expenditures by fetching advantage of the various rate structures ready(prenominal) to purchasers and being aware of which available rates may be applicable to them.ConclusionEnergy and utilities make for a significant and highly volatile playing area of expenditure for most businesses. However, traditional energy management approaches frequently fail to deliver sustainable results. Many managers consider high energy spend as an area that cannot be addressed due to market regulations and commodity volatility. However, with continuous monitoring and Active Energy Management programs, leading firms can obtain substantial energy cost savings through better energy demand management, sustain those savings through ongoing monitoring and optimize energy purchases with deep market intelligence.
