Express Energy Audit (About & Benefits)

Energy Audit is a periodic exercise carried out once every 2-3 years by Industrial or Manufacturing plants depending on the plant size, Govt. regulations, plant type etc. It definitely results in Energy Conservation & Energy Efficiency for the plant by -

  1. Identifying and plugging energy leakages
  2. Adoption of new technology trends such as IIoT (Industry 4.0)
  3. Improving operational efficiencies
  4. Installing new age technical equipment and retrofits
  5. Using alternative and green sources of energy
The above is carried out in a phase-wise manner with detailed measurements, data collection, team discussions, presentation, RoI & payback calculations. Detailed Energy Audit Report is submitted with all the observed, measured and calculated data along with energy saving recommendations with a payback of typically less than 12 months and in some case more. The obvious benefit of energy audit is cost-saving which consequently results in higher profitability by cost-control.

It is observed that several times Companies or plants would just like to go for a basic check about Energy Saving and may not necessarily wish to go for a comprehensive Energy Audit in such cases an Express Energy Audit is recommended.

What is an Express Energy Audit?
It is an exercise carried out for a plant to identify energy saving potential of the plant. The audit can last for 2-5 days depending on the plant size and includes -
  1. Walk-through of the facility to for visual inspection of the plant setup and the processes.
  2. Identification of visually identifiable energy saving opportunities.
  3. Discussions with the plant team on the various challenges and opportunities.
  4. Understanding the plant energy consumption (Power, Coal, Diesel, LPG, PNG etc.).
  5. Estimating the total energy saving potential of the plant.
  6. Identifying opportunities for captive rooftop and ground-mount Solar potential in the plant with project sizing.
  7. Evaluating the energy saving measures and projects undertaken since the last detailed energy audit.
Benefits of Express Energy Audit
Express Energy Audit is beneficial to a plant in more ways than one. Few of the benefits of Express Energy Audit are -

  1. Carried out by the same team of B.E.E. Certified Energy Auditors (IIT-B alumnus) & Engineers which carry out detailed Energy Audits.
  2. Helps in continuing the momentum of Energy Optimization within the plant.
  3. 3rd party verification of a recently carried out Energy Audit or recommendations made in a detailed Energy Audit.
  4. Costs a fraction of detailed energy audit but can yield good results (Typically around 1% savings straightaway).
  5. Enables a plant to understand if a detailed energy audit would be beneficial at a particular stage or not.

Energy Audit Planning - Things to know !

Energy Audit Planning - Things to know !

About

Energy Audit is a periodic exercise carried out by Industrial plants and Commercial facilities. This exercise carried out by B.E.E. Certified Energy Auditors and Energy Experts can enable a plant to save 8% to 15% on it's Energy Bills by easy-to-implement and difficult-to-identify energy conservation and energy efficiency measures.
Energy Audit in progress

Based on our experience of 500+ Energy Audits (check out our customer list) we can say that every Industrial plant or manufacturing unit certainly has the potential to save energy. This is due to a variety of factors such as 
  1. Ageing plant equipment / machinery.
  2. Emerging and evolving technologies for better resource optimization.
  3. No dedicated plant team or cell to focus on Energy optimization matters.

Cross-domain B.E.E. Certified Energy Audit team from outside the plant (Enerco) brings in a fresh perspective along with experience of similar and varied types of plants.

Generally an Energy Audit is recommended once every 2 years depending on the size and power + energy consumption of a plant. It is also recommended that a walk-through energy audit be carried out in the plant at least once a year. An annual walk-through energy audit ensures that plant is performing at an optimum level and Energy Conservation and Energy Efficiency becomes a way of life and not just a one time activity.


Things to know at Energy Audit Planning Stage

If you are planning for Energy Audit then you should know a few things before proceeding for Energy Audit. It will help you save time, money and efforts before making the final decision.

Point 1 : Set realistic expectations
Energy saving potential exists in all types of Industrial plants in utilities, processes etc. However the saving for each plant will differ from the other due to the uniqueness of the plant in terms of sector, age, location, manpower etc.

(Others are also reading : Energy Saving = Higher Profitability)

Point 2 : Estimate the Energy Saving potential
A team can be setup to estimate the energy saving potential in the plant before actually assigning the task of Energy Audit to an expert agency. This will help in effective communication during Energy Audit and implementation post audit. An external team can also assist with this exercise through Express Energy Audit (next point).

Point 3 : Express Energy Audit - a starting point
Express Energy Audit is about a walk-through energy audit with certain basic measurements and data analysis. It lasts for a few days (2-5 days) depending on the plant size but gives a good insight into the energy saving potential of the plant and also whether a detailed energy audit would be fruitful at this stage or not. To know more about Express Energy Audit visit our site section on Express Energy Audit. Alternatively you may check out our recent blog post about Benefits of Express Energy Audit.

About Express Energy Audit


Point 4 : Brainstorming of plant people
Brainstorming sessions help in identifying improvement points within the plant before going for an energy audit. Ideally cross-functional teams work the best during such sessions.


A good starting point for Energy Audit planning is the Express Energy Audit. This exercise is recommended for a plant -
  1. Which is considering a detailed energy audit but would like to know if the detailed exercise would be useful at this stage.
  2. Which has never carried out energy audit but wants to estimate the energy saving potential.
  3. Interested in Energy Conservation and Energy Efficiency but does not know where to begin.

Energy Audit - Energy Saving Guide for Industries

Energy Audit - Energy Saving Guide for Industries 

Energy Audit certainly benefits all types of plants - irrespective of size or type or age. While the energy saving opportunities might differ., there is no doubt that energy audit does result in energy saving.

Each Industrial plant is unique and has it’s own opportunities and challenges., although there are some common areas wherein a plant could benefit from implementing most common Energy Conservation and Energy Efficiency measures. It is observed that majority of the Industrial plants (nearly 80%) can save good amount of energy by focusing on below areas. Of course these are only general guidelines and exact savings, investments, payback would be plant specific and is understood better during detailed energy audit.

1.  Compressed Air System
Observations :
a.   Manual loading and unloading
b.  Idle running
c.   Obsolete starting methods
d.  Manual intervention
e.   Leakages in Compressed Air System
f.    Maintenance

Recommendations :
a.   Automation for synchronization
b.  Adoption of advanced starting methods
c.   Arresting leakages in compressed air system
       
2.  Pumps
Observations :
a.   Efficiency deviation from design
b.  Damages to pump internals – impeller or casing
c.   Malfunctioning valves
d.  Ageing
e.   Maintenance
Recommendations :
a.   Impeller re-sizing
b.  Higher maintenance focus
c.   Replacement of ageing pumps (can payback within months)
3.  Fans & Blowers
Observations :
a.   Impeller sizing issues
b.  Obsolete control mechanisms
c.   Maintenance
d.  Throttled Dampers
e.   Efficiency deviation from design

Recommendations :
a. Automation for fan speed adjustment.
b. Repair of internal damages.
c. Higher focus on maintenance.
d. Better damper control.

It is observed that above 3 areas contribute to nearly 10% to 20% of total energy saving opportunity in a typical plant. In majority of the cases minor tweaks in operational practices can lead to huge savings i.e. zero investment recommendation with immediate payback.

Some of the cases include incorporation of newer technologies which help in better control of energy usage. In a few of the observed cases it was recommended to adopt newer technologies for improved energy performance. Any cost implications of new technologies was suitably supported with quick RoI / payback of 9-12 months. In all cases the recommendations had a payback of lesser than 24 months as is accepted by majority of the Companies.

There are other common areas within every plant which could be explored for further energy saving which are as below.

Other common areas for Energy Saving –
A. Using Rooftop Solar for captive use (significant savings)
Ø  Variety of financial models including ZERO upfront payment under BOOT / RESCO
Ø  Power cheaper than Electricity Board / DISCOM / Utility
Ø  Can result in 10% to 30% saving on Electricity Bill per month
Ø  Simple payback of 3-5 years for self-financed project which is attractive considering 20+ years of PV Solar life.

(Check out : How Solar Energy can boost your Company's Profits)

B. Replacing lighting with higher efficiency lights (miniscule savings)
Ø  Newer and evolving technologies such as LED, Sky lamp etc.
Ø  Can result in 1% to 2% saving on Electricity Bill per month.
Ø  Simple payback is less than 1 year for majority of the replacements.


Conclusion
Energy Audit is a highly customized exercise carried out for plants and can result in SEC (Specific Energy Consumption) reduction of anywhere between 2% to 7%. The actual saving depends on a variety of factors but overall it is almost always possible to identify areas for energy saving.
The savings can have a huge impact on a plant’s revenue and profitability based on the actual cost composition in overall plant manufacturing. 

With ever-rising grid tariffs, cost of basic energy (coal, oil, gas etc.) it definitely makes a strong business case for a plant to carry out Energy Audit. For plants which have never carried out energy audit there could be shocking revelations on this front. For plants which periodically carry out energy audit, this exercise helps in identifying niche areas for energy saving as well as keeping up the momentum.

While major energy saving lies in the process specific to a particular unit, the utilities present a generic energy saving opportunity for a plant. These energy saving opportunities are basically “low-hanging” fruits that can be used to capitalize on energy optimization by any plant – irrespective of it’s process or age or composition. By adopting few simple methods as outlined in the observations in the previous section, a plant can certainly expect to save some amount of energy., which is a welcome positive step. With additional measures the energy saving initiative could be taken up further.

Moreover a detailed energy audit reveals far more opportunities which can have a significant impact on a Company’s profit margins. Many companies are waking up to this fact and are adopting energy saving measures as a Company wide policy and not just as a one-time exercise. ISO 50001 is another step in that direction which indicates how well a Company is using it’s energy resources. Customers are satisfied in more than 90% of the cases wherein Energy Audit was carried out for the 1st time. Majority of these customers have vowed to carry out frequent and periodic energy audit to ensure maximum benefits and for maintaining continual momentum for energy saving within the plant.

Energy Audit - Is it the right time for your plant?

Energy Audit - Is it the right time for your plant?

Energy Audit is a periodic exercise undertaken by a plant to assess it's energy consumption and identify opportunities for Energy Conservation and Energy Efficiency. It also helps a plant personnel in modernizing the plant inline with new technology solutions.

The question is why is it periodic and not a one-time activity. The answer lies in the dynamic nature of manufacturing industry - both internal and external. With the advancement in technology there are better and more energy efficient ways to carry out the same activity. For eg. use of higher efficiency equipment such as Compressors or motors or Boilers. By use of contemporary solutions a company could ensure more bang for the buck. A plant which stays in the status quo mode with the belief that it's performing at it's best would soon witness oblivion.

Additionally a plant undergoes modifications over a period of time which may impact it's energy balance thereby presenting newer opportunities for deployment of Energy Efficiency practices. Modifications may include enhancement of capacity, new product addition, introduction of new equipment or replacement of old or worn out equipment etc.

Increasing competition from the Global and new Local competitors should be one of the major driving forces to achieve optimum energy levels. It is no surprise that plants across the Globe are striving to achieve optimum cost of production to stay ahead of the competition. Energy is indeed one of the most expensive resources which can significantly impact the production cost - both positively and negatively. Energy Efficiency and Energy Conservation should be viewed as a strategic tool to achieve competitive edge.

To understand if this is the right time for your plant to go for Energy Audit we have prepared a check-list. The answers to this checklist would give you a fair idea if Energy Audit is recommended for your plant or not. This is particularly important if you are expecting significant energy saving from the Energy Audit. There are cases wherein a plant carries out Energy Audit to cross-check or verify their correctness of operations as well.

If you are still not sure, you may go for EXPRESS Energy Audit. More details about the same can be found in our blog post - Express Energy Audit and it's benefits.

In any case it would be worthwhile for you to get this FREE analysis done. Simply send a mail to info@econserve.in and we will guide you to the next steps.

Does Energy Audit really save energy?


Energy Audit is the first step towards Energy Conservation & Energy Efficiency. In fact Energy Audit itself may consist of 3 steps i.e. Preliminary Analysis, Walk-through Energy Audit (aka Express Energy Audit) and Detailed or Comprehensive Energy Audit.

The steps may sometimes be combined but some Companies may skip a step or in some cases combine them as well. Express Energy Audit is used by Companies to only estimate the potential energy saving in the plant. Although finding out visible areas of savings are possible through Express Energy Audit. With regards to Detailed Energy Audit., it definitely digs in deeper to identify all possible energy saving opportunities within the plant. A well-documented report with recommendations backed by data is the outcome of detailed Energy Audit. Do visit our website to know more about each type of Energy Audit.

There are definite reasons that Energy Audit is not viewed as a wholesome exercise by many. The variety of reasons are at operational level as well as based on past experience by a few of the decision makers who have been involved in previous such exercises -

  1. Misconception that Energy Audit in itself would save a lot of Energy.
  2. Energy Audit being carried out by inexperienced and incompetent teams.
  3. Recommendation implementations not taking place resulting in no conclusive outcome of Energy Audit.
  4. Recommendation implementations not approved despite good savings potential.

Etc. Etc.

[Can Solar Energy Projects work across India?]

With various factors considered it is sensible to assume that an Energy Audit in itself will not save significant energy. Although Energy Audit itself does save some energy and the savings can be in the range of 6-8% achieved by changing certain operational parameters, visible areas of saving by bench-marking, ergonomic factors, enhanced awareness etc.. In case of purely Electrical Energy Audit the savings can be on the higher side of range band through the Energy Audit itself. To achieve significant saving retrofits and equipment replacements are needed as per the recommendations mentioned in the Energy Audit Report. However to obtain appropriate recommendations for operational changes, retrofits and replacements inline with the process and operational requirements is what Energy Audit is all about.

In a nutshell Energy Audit is the first crucial step in the direction of Energy Conservation & Energy Efficiency Project. If carried out in a systematic approach by experts in this field - energy saving can be expected as an outcome of the exercise. The other outcome of course is the report which lists out the recommendations. With ever-rising Energy Costs it is imperative for Industrial Plants to carry out periodic Energy Audit and implement the solution as well to achieve greater results.

Energy Conservation Project generally follows the below cycle -

Energy Audit, Energy Conservation, Energy Efficiency


[Is Solar Energy really afforable?]

Another interesting point is about measuring the savings and if savings have actually been achieved in a plant after an Energy Audit. In general a comparative analysis of energy consumption before and after audit will not reveal true results as energy consumption generally is not constant for any given plant due to seasonal changes, market demand for the product (being manufactured), internal factors etc. Specific Energy Consumption is the term which is used to denote the Energy required or Energy invested (Electricity, Coal, Diesel, Fuel etc.) in producing one unit of a product. With a setup having more than one product the SEC for each of the product needs to be calculated and will give a true indication whether an Energy Conservation and Energy Efficiency has been achieved or not.

With an aim to reduce Specific Energy Consumption an Energy Audit should not be carried out in isolation but should be looked at as part of an overall Energy Conservation Project and hence Specific Energy Consumption (SEC) or Specific Power Consumption (SPC) should be closely monitored as an ongoing practice to achieve good results. It is known fact that energy saving is not a destination but a journey.

Updates of Oct 2019
Based on our past experience a Company can save anywhere between 5% to 12% on Energy Bills. This includes - Electricity Bill, Fuel Bill (Diesel, F.O., Coal, LPG etc.). For a typical plant this could mean savings of 2% to 5% on it's production costs.

The range of energy saving is based on our past experience of 300+ Energy Audits and is based on practically implementable solutions. We are in the process of documenting energy savings achieved through energy audit assignments by preparation of a Comprehensive Report with data for a variety of Industries. For now you might find it useful to download our Energy Audit Case-Study for a recent assignment. The customer was able to save 10% Energy and consequently 2.5% on production costs.

Download the Energy Audit Case-Study to know more about details of the Energy Audit, our approach, findings, recommendations etc. for this plant.

If you are planning for Energy Audit, there are certain things that you should be aware of. Why not check our blog post on the subject - Energy Audit planning - things to know !

New Age Industrial Energy Audit

Conventionally Energy Audit has been more about Demand Side Management i.e. improvement on Load Side to result in Energy Conservation and enhance Energy Efficiency of the Plant or Facility. However with recent developments and interest in Captive Power Generation Energy - Industrial Audit will not and should not only focus on Demand Side Management but also on Power Generation especially from Green Sources like Solar Energy.

In general Energy Audit as a concept has been more concerned with improvements in existing setup and also a part of it including in retrofits which in most likely scenarios will be additional equipment being installed or replacing outdated plant equipment. There is an interesting shift especially by the Industries in exploring the option for Captive Power generation especially through Green Energy Sources such as Solar Energy.

[Suggested Read - Is Solar Energy really Affordable?]

Industrial Clients are now interested in a more holistic approach to the Energy Solutions and hence look at possible alternative energy. It also makes lot of Commercial Sense to have a Power Portfolio with the right kind of Power Mix. It is quite evident that in such a scenario - Photo Voltaic Solar will play a crucial role in Captive Power Generation thereby reducing some dependence on Grid Power - in whatever small way possible.

Referring to the context in Indian Industries an Energy Audit should adopt a very systematic approach. Primary purpose of Energy Audit is to explore areas and opportunities for Energy Conservation and Energy  Efficiency. However an Energy Audit in itself may save Energy as mentioned in the recent post (Does Energy Audit really save Energy?). Energy Audit should primarily consist of :
  • Detailed understanding and study of existing system and setup and devising ways and means to reduce Specific Power Consumption.
  • Analysis of Power Consumption Trend and suggesting measures for improvement in the same and stabilizing the consumption.
  • Identifying the Present Power Portfolio and Designing the Ideal Power Mix.
  • Exploring possibility of Greener and More Efficient Fuel Alternatives.
  • Identifying Opportunities for Renewable Power Sources - based on Geography.
  • Follow Up visits to ensure that Recommendations schedule is adhered to.
  • Training Session to create awareness regarding Emerging Technologies in Renewtech and EE & EC.
Etc.

From an Industrial point of view Energy Audits should look at more of a comprehensive approach than just as a starting point of reducing Production Cost. Energy Audit Checklist generally forms a good basis for Energy Auditors to carry out Energy Audit.

In the Global context Industries are focusing more on reducing their carbon footprint - necessitated by Governing Environmental Laws. Strict enforcement of such laws postulates that Industrial Energy Audit goes a step beyond the conventional approach and adopts newer technologies for not only Demand Side Management but also for Green Power Generation.

With increased environmental awareness the pressure on Industries is mounting to reduce their Carbon footprint by adopting Greener Methods wherever possible. In such as Scenario Energy Audit would play a crucial role in offering Industries a Comprehensive Approach towards a Greener Plant. Most Frequently asked Questions on Solar Energy can be found on our Post - Solar Energy FAQs.

Industrial Energy Audit - A Perspective

Energy Audit is a very important periodic exercise carried out with the objective of achieving Energy Conservation and improving Energy Efficiency - mainly for Industrial Plants and Commercial Facilities. Some States have a mandate for Energy Audit to be carried out by designated Industries once every 2-3 years. Why is Energy Audit so important and why have a mandate in place for something so useful is a flummoxing question.

As a matter of fact every Industrial Plant or a Commercial Facility - however efficiently run will have scope for Energy Saving. There are various reasons for the same -

  1. Dynamic Changes - every plant / facility undergoes some changes (expansion / addition / removal) over a period of time and the overall energy consumption and trends may change because of this.
  2. Emergence of Advanced Technology Equipment and Retrofit which save significant energy due to efficient running.
  3. Critical Assessment including Advanced Thermography for Thermal Energy Audit and Power Quality Check (especially for Harmonics) for Electrical Energy Audit.
  4. Not having a dedicated Energy Cell to monitor and report Energy usage and suggest corrective actions for the same. Many Industrial Plants still rely on Production or Maintenance Teams for the same. Energy Cell is especially recommended for Industrial Plants and specifically for Energy-intensive Industries.
  5. Ageing of Equipment.
  6. Lack of awareness regarding energy saving potential of the plant or about Energy Audit in general with specific plant related inputs.
  7. Not undergoing an Energy Audit. Even for the plants having a dedicated Energy Cell or a Energy Manager - an Energy Audit will prove fruitful. This is because an Energy Audit from a vendor brings in experts from diverse Industries who are dedicated towards achieving results in this domain.
  8. Plant People focus on their primary responsibility. For instance a department HOD may focus only on the domain maintenance and improvements in the particular domain which maybe viewed in isolation. An Energy Audit looks at holistic picture to suggest improvements in the plant.
  9. Although plant people are highly capable there might be times that simpler measures such as operational efficiency may be overlooked- which may deteriorate over a period of time.
  10. Improper maintenance for short-term gains.
  11. Cross-Industrial and Cross-Domain Experience which may not be found within any single plant but may certainly be found in a single Service Provider.
So why despite the ever-rising running costs and Energy Costs are Indian Industries not carrying out Energy Audit on a bigger scale? The answers could be many but the primary reason is the Myths surrounding the Audit. For instance many consider Energy Audit to be the Energy Saver exerciser without any further investment. However the fact remains that Energy Audit is the first step in the direction of Energy Optimization of a Plant. The exercise begins with initial visit or collection of data in the Energy Audit Questionnaire. The Questionnaire is generally filled up by the Plant team and submitted back to the Service Provider / Energy Auditor. On receiving the same the Service Provider proceeds with preparing a Comprehensive and Customized Scope of Work for the Plant. The primary objective of Energy Audit is to explore potential areas for Energy Conservation and Energy Efficiency including the ones which require No Investment. So in some sense Energy Audit in itself can also save energy. Although there are recommendations in the Energy Audit Report which indicate retrofits which require investment. However with the due care that the Investments are justified.

It has also been observed that in some few cases Energy Audit is carried out by inexperienced and un-certified engineers who may have no previous experience in this. This impacts the overall outcome and may not actually meet the primary objective of Energy Audit. In such cases an Organizations which are not satisfied with the past Energy Audit are discouraged from carrying out future Energy Audits as well. As a practice Organizations should duly check the experience and expertise of the Vendor. In general Energy Audit is carried out of Electrical and Thermal Utilities and as such a similar Industry experience may prove to be beneficial but may not be deemed necessary. This is because more or less the composition of Electrical and Thermal Utilities remain the same - irrespective of the type of Industry. If however a Process Audit needs to be done then a Domain expert can add value to the exercise.

Energy Audit is the beginning of Energy Saving in a plant and is recommended for almost all the Industries - irrespective of size and type. In the Indian Context Energy Audit has a special role to play as India faces tremendous power shortage (about 10% Peak Deficit) and also the potential for Energy Conservation is estimated at a mind-boggling 25,000 MW.

It may be worthwhile to mention that the exercise bears results for Industries having either a load of above 400 kVA or good Steam Consumption & Boilers. In case a Plant or Facility has both - then a periodic Energy Audit is highly recommended. The frequency of audit may differ from plant to plant and is typically once in 2 years for detailed energy audit. In addition to this a walk-through audit twice a year ensures that Recommendations are implemented and momentum is kept strong. This also ensures that Energy Conservation and Energy Efficiency becomes a way of life in the plant and taps the potentials at grass-root level.
