Conservation Cells & StrategiesConservation Cells & StrategiesConservation Cells & StrategiesConservation Cells & Strategies

SummarySummarySummarySummary

Under the Energy conservation Act, all thermal power plants falling under Designated

Consumers category is to nominate or appoint certified energy manager apart from setting

up an energy management cell.

Detailed survey was carried out by circulating the questionnaire to all designated

consumers of thermal power plants to obtain the status on the following:

• Establishment of energy efficiency cells

• Engaging of certified energy managers

• Roles and responsibilities

• Organizational structure pertaining to energy conservation cell

• Present status of procedures to measure energy efficiency

The responses received were analysed and tabulated. The following gives the brief

summary of the survey report.

a) Response:

Responses from 34 different types of power plants are received. Most of the responses

(65%) are pertaining to coal fired units. The cumulative installed capacity of the responded

plants is about 19820 MW. More response is received from southern region (i.e., about

49%).

b) Energy Management Policy:

Energy management policy provides foundation for successful energy management and

formalises the top management support.

Only one third of the plants have declared energy management policy. This indicates need

for such effective energy management policy. The observed missing points in the policies

are accountability, energy saving targets, monitoring and review, training, criteria for

investment on energy conservation, etc.




Date 08.01.2008


c) Energy Conservation Cell

About 60% of the thermal power plants (20 out of 34 plants) have energy conservation cell

and in majority of the cases (16 out of 20 plants) energy conservation activity additional

responsibility to the existing functions.

The staff strength of energy conservation cell varies from one to eight. In most of the

cases there is no representation from vital departments, which can provide effective inputs

for EC cell operation.

It is also observed that, the features of energy conservation cell pertaining to functions,

meetings, strategies, and finances are not clearly defined by many plants.

d) Energy Manager Nomination

Fourteen plants out of 34 have nominated energy managers. Twelve of fourteen nominated

energy mangers are certified by the Bureau of Energy Efficiency. The roles and

responsibilities are not clearly defined in most of the cases and these need to be defined

based on the EC Act.

e) Energy Accounting & Monitoring (EAM)

More than 76% plants have energy accounting and monitoring system, how ever this

responsibility is carried out by different departments, only in 14 cases out of 26 (i.e, 41%),

EAM is responsibility of energy cell.

It is also observed that though 20 of plants have EC cell, only 14 EC cell are engaged in

Energy Accounting and Monitoring.

f) Present status of procedures frequency to measure efficiency and energy performance

The energy efficiency and energy performance monitoring of boilers and turbines is carried

out by 62% of the plants. How ever the monitoring frequency is varied from plant to plant.

It is also observed that still 38% of plants do not carryout this exercise.

In case of auxiliaries, about 47% of the plants do not carryout this task and some of the

plants (about 12%) mentioned that this is activity is carried out during the energy audit.




Date 08.01.2008


g) Constraints

The major constraints listed by the respondents are pertaining to technical aspects. The

other constraints include instruments availability, manpower, training, finances, etc.

h) Way forward

In view of the observations and findings derived from the survey, it is essential to draw the

most preferred energy conservation strategy, which includes options suited for Indian

scenario.

1.1.1.1. IntroductionIntroductionIntroductionIntroduction

Under the Energy conservation Act, all thermal power plants falling under Designated

Consumers category needs to take up specified activities. One important activity for

Designated Consumer is to nominate or appoint energy manager possessing certified

energy manager certification from Bureau of Energy Efficiency (BEE) apart from setting up

an energy management cell.

The energy manager and energy cell occupies an important position in the organisation.

Energy manager will be the focal point of all the activities pertaining to energy

management in the organization. Energy manager will have certain mandatory duties &

responsibilities to fulfil the EC act requirements by the designated consumer. The energy

manager is expected to:

• Play key role in the framing and formulation of corporate energy management policy

• Develop an energy management action plan for the thermal power plant

• Furnish information relating to energy consumption to the BEE and State level

Designated Agency (SDA)

• Implement the recommendations of the accredited energy auditor

• Review and monitor of energy consumption.

• Reduce the energy consumption / set new targets

• Bring awareness on energy efficient technologies with in the plant

• Several other functions.

In view of the above, a survey of thermal power plants was under taken to review the

following:

• Establishment of energy conservation cells and organization structure

• To what extent certified energy managers hired/ nominated

• Roles and responsibilities of energy cells / energy managers

• Energy accounting and monitoring systems

• Energy efficiency and performance monitoring systems

In some of the cases, the policy is attached and it is not merely energy management policy.

The some of the missing points (observed) in the policies are:

• Who is accountable for energy management?

• What are energy savings targets (quantitatively) are?

• How monitoring, review and report on progress will take place?

• Staffing and training to support the policy

• How energy policy will be integrated into wider business processes?

• Criteria for energy management investment

• Energy efficiency aspects into new capital investments

Energy management policy provides the foundation for successful energy management. It

formalizes top management's support. It is targeted to articulate the organization's

commitment to energy efficiency for employees, shareholders, the community and other

stakeholders.

A formal written energy policy acts both as:

• A public expression of the organization's commitment to energy conservation and




Date 08.01.2008


environmental protection

• A working document to guide the energy management practices and provides

continuity

It is in the company's best interest that support for energy management is expressed in a

formal written declaration of commitment accompanied by a set of stated objectives, an

action plan for achieving them, and a clear specification of responsibilities.

Typical format of an Energy Policy should contain

• Declaration of top management's commitment and senior and middle management's

involvement in energy management.

• Statement of policy

• Statement of objectives indicating the reduction in specific energy consumption,

separated into short and long-term goals

Actions to be included in energy management policy are:

• Have the CEO or head of the organization officially issue the policy

• Involve key people in policy development to ensure cooperation

• Tailor the policy to the organization's culture

• Make it understandable to employees and public alike

• Consider the skills and abilities of management and employees

• Include detail that covers day-to-day operations

• Communicate the policy to all employees, and encourage them to get involved

Guideline to make well written energy management policy –

Source: Energy management handbook, by Wayne C. Turner, Steve Doty

A well-written energy policy that has been authorised by management is as good as

the proverbial licence to steal. It provides the energy manager with the authority to

be involved in business planning, new facility location and planning, the selection of

production equipment, purchase of measuring equipment, energy reporting and

training- things that are sometimes difficult to do.

If plant already has an energy policy, chances are that it too long and cumbersome.

To be effective, the policy should be short-two pages at most. Many people confuse

the policy with a procedures manual. It should be bare bones, but contain the




Date 08.01.2008


following items as a minimum;

• Objectives: This can contain the standard motherhood and flag statements

about energy, but the most important is that the organisation will incorporate

energy efficiency into facilities and new equipment, with emphasis on life

cycle cost analysis rather than lowest initial cost.

• Accountability: This should establish the organisational structure and the

authority for the energy manager, coordinators, and any committees or task

group.

• Reporting: Without authority from top management, it is often difficult for

the energy manager to require others within the organisation to comply with

reporting requirements necessary to properly managed energy. The policy is

the place to establish this. It also provides a legitimate reason for requesting

funds for instrumentation to measure energy usage.

• Training: If training requirements are established in the policy, it is again

easier to include this in budgets. It should include training at all levels within

the organisations

Many companies, rather that a comprehensive policy encompassing all the features

described about, choose to go with a simpler policy statement.

Twenty power plants (i.e., 59% of respondents) have already established EC cells, which

indicates that several plants (41%) are yet to establish EC cell.

Another observation is that only 11 plants have declared energy management policy, which

indicates that the nominated energy cells need to work out on energy management policy.

From filled in questionnaires, it is also observed that CEA guidelines CEA guidelines CEA guidelines CEA guidelines have helped in setting

up energy conservation cell.

Energy conservation cell is headed by the energy manager and energy conservation is

either exclusive or additional responsibility.




Date 08.01.2008


The response indicates that, by and large energy conservation is additional responsibility.

Only in four plants out of 20 energy conservation cells have Energy conservation as

exclusive responsibility.

The following (Figure 4-2) gives the break up of the of plants where EC cell is established

4.1.64.1.64.1.64.1.6 Energy Accounting and monitoring Energy Accounting and monitoring Energy Accounting and monitoring Energy Accounting and monitoring

Most of the plants (75%) have energy accounting and monitoring systems. The feed back

indicates the energy accounting and monitoring is carried out by different type of

departments such as:

• Energy cells

• Operation and maintenance department

• Electrical department

• Statistics department

• Planning department

The following (Figure 4-4) gives the status of energy accounting and monitoring

procedures in the responded power plants.

The major observations are:




Date 08.01.2008


• About 75% of the plants (26 out of 34 plants) are having energy accounting and

monitoring procedures in place

• Though 20 plants of 34 plants (59%) have energy cells, only 14 plants (41%) have

engaged energy cells in energy accounting and monitoring, which indicates, energy

cell are not very active in all plants.

• It is also observed that other departments are looking after energy accounting and

monitoring, though Energy cell are created in the plant.

The list of the plants along with department name looking after energy accounting and

monitoring is given in Annexure VI.

4.24.24.24.2 Energy AuditEnergy AuditEnergy AuditEnergy Audit

The survey indicates (Figure 4-5) that, only 18 plants (out of 34) have carried out energy

audit during the last three years, which indicates huge gap in implementing energy

management programs since energy audit is essential.

out, which indicates need for introduction of such practices

• The frequency of efficiency evaluation vary from daily to once a year

• It is also observed that online systems are also being used to measure efficiency and

energy performance

• About 38% of the plants monitor boiler performance on monthly basis

• Plants are following heat loss method to evaluate boiler efficiency

• There is a request to CEA from one plant to set up procedures and practices for

efficiency evaluation

• In one case, it is mentioned that “no set procedures have been defined so far to

measure the efficiency/ energy performance” which indicate necessity to set up

procedures and practices.

4.44.44.44.4 Constrains Constrains Constrains Constrains

Many plants have listed technical/operational and maintenance constraints instead of

listing constrains related to implementation of energy conservation measures. These

constrains are classified in to the following categories

4.4.14.4.14.4.14.4.1 Technical / expertise related constrains Technical / expertise related constrains Technical / expertise related constrains Technical / expertise related constrains

• Units are being considered for the renovation and modernization

• Complex layout of common auxiliaries and difficult to quantify unit wise share of

energy consumption.

• Poor response of external agencies as stations are located in remote area

• As there is no separate Energy cell formed, and operations department monitors the

plant performance on a daily basis and highlights any significant deviations, to initiate

concrete action by other departments. By forming an energy cell with proper resource

allocation, the energy conservation efforts can be stepped up further.

• Residual life of the plant is the main constrains to implement the major and high

cost Energy Conservation Projects

• Inadequate proactive maintenance

• Unpredicted generation requirement from grid. The Plant output varies based on

load requirement from grid.




Date 08.01.2008


• Low Level of generation for very longer periods

• Delayed overhaul of units

• As no energy conservation measures have been set up to effective implementation

of the same is not feasible.

• For modification in critical equipments one has to wait for annual shut down

• Plant load pattern is not uniform throughout the day and year opportunity to utilize

waste heat recovery is not available.

• There is no exclusive department for Energy Conservation

• Since machines are old and refurbishment is in progress hence after that

conservation measures will be made

4.4.24.4.24.4.24.4.2 InstrumentsInstrumentsInstrumentsInstruments

• The necessary instruments required are not available

• Lack of latest instruments required for the work are not available

• Comprehensive and accurate instrumentation is the main constraint for

implementing energy conservation measures

• Individual equipment does not have energy meter for calculating energy

consumption separately.

• Adequate Equipments & Instrumentations

4.4.34.4.34.4.34.4.3 Training / Manpower Training / Manpower Training / Manpower Training / Manpower

• Shortage of Skilled man power

• Training of personnel of the EC cell is required to make the cell efficient and

effective

• Man Power Shortage

• Inadequate awareness regarding energy saving potential among stakeholders

• Lack of man power (i.e energy conservation cell has been vested with additional

responsibility apart from their regular works)




Date 08.01.2008


• Shortage of manpower due to Mass retirements

• Shortage of Trained / Experience manpower exclusively for energy conservation cell

4.4.44.4.44.4.44.4.4 OthersOthersOthersOthers

• Financial crisis

• Power crisis

• Adequate Finance

• Only short term/without finance measures has been implemented

List of constraints based on plant wise are given in Annexure X. It can be seen that

though there are several technical constrains (which are mostly case specific), the major

constraints in implementing the energy conservation are related to man power,

training, instrumentation apart from mobilizing the finances for implementation

4.54.54.54.5 Summary and Conclusion Summary and Conclusion Summary and Conclusion Summary and Conclusion

The report has highlighted the present status on the energy management in the thermal

power plants, which indicates several gaps. There is need to workout for the energy

management strategy, which include the following:

• Energy management policy

• Establishment of energy conservation cell and designing of appropriate structures

along with functions and strategies of energy conservation cells

• Energy managers nomination – defining the roles and responsibilities
