    BACKGROUND

    India has a total installed capacity of is nearly 2, 05,340 MW as of June, 2012 plus captive

    power plant produces additional 31,500 MW of power. The break-up has been shown in the

    chart below. Power is in the concurrent list of Constitution, due to which both the Central andState laws can be implemented, however in case of any clash, the Central law shall prevail. The

    country had been achieving a growth rate of nearly 8% in the past few years but lately, the

    situation looks gloomy and a growth of even 7% seems to be very ambitious. In such times the

    notion of saving electricity is very crucial for the country, not only for economical but also

    developmental reasons. The present power system in the country is struggling to overcome

    chronic power shortages and poor power quality. With demand exceeding supply, severe peak

    (around 18%) and energy (around 12%) shortages continue to plague the sector. Shortages are

    exacerbated by inefficiencies in power generation, distribution and end-use systems. The

    inefficiencies in the end-use systems is due to irrational tariffs, technological obsolescence of

    industrial processes and equipment, lack of awareness, nascent energy services (ESCO)

    industry, and inadequate policy drivers (such as energy efficiency standards and labeling

    system, financial incentives) in India.

    The elementary problem being faced by the power sector is the poor financial conditions of the

    State DISCOMs or predecessor entities in most states. Over the years, the SEBs had been

    causing an increasingly larger drain on the State Government budgets, now the legacy

    continues with the State DISCOMs contributing to 10-15% of the state fiscal deficits adversely

    impacting much needed investments in the social sectors of health and education. The powersector is operating with very low or no returns on the equity and no contribution to future

    investments from internal resources. This results in inadequate investment in additional

    generation capacity which is likely to further exacerbate the existing gap between power

    supply and demand.

    Thus, the Indian power sector faces two fundamental and interdependent issues: inferior

    operational performance leading to poor revenue cash flow, and as a consequence, inadequate

    capital mobilization for sector expansion. Current approaches do not completely address these

    issues. Power sector plans focus exclusively on new supply and lately, to an extent, on

    improving supply efficiency and reducing T&D losses (for instance, the latter through the

    RAPDRP). A major opportunity lies in the DSM system in the country, which is yet to be utilised

    properly.The historic problems of the Indian power sector can be traced to three root issues

    unacceptably high T&D losses, large commercial losses due to poor billing, metering, collection

    and energy theft, and, low end-use efficiency of energy use specifically in agriculture. There isnow widespread agreement that restoration of the financial health of the sector can be only

    enabled by demand side initiatives. To be specific, the electricity distribution area is where the

    historic problems converge. This convergence is most felt in the agricultural sector where the

    water-energy nexus is a major root cause for the precarious financial condition of the power

    sector in India today.

    Water withdrawal is an energy intensive operation throughout the agricultural sector, with the

    result that 30-40% of Indias power consumption is used for irrigation. The irrigation pumping

    electricity use is at the heart of the subsidy issue and along with electricity theft and T&Dlosses, comprise the root cause for the sectors financial dilemma. The reasons a power utility

    in India may undertake DSM include: a) demand outstripping the capability to provide supply,

    particularly peak supply, b) improve the cash flow revenues of the utility, c) improve the quality

    and reliability of power supply, and d) mitigate the impact of rising tariffs to the subsidised

    customers. For agricultural sector particularly, utility DSM is highly beneficial because of the

    subsidized prices and high costs of supply resulting from technical and commercial losses.

    DEFINITION AND SCOPE OF REPORT

    Demand Side Management (DSM) is described as the planning, implementation and monitoring

    of utilitys activities designed to encourage customers to amend their electricity consumption

    patterns, both with respect to timing and level of electricity demand so as to help the

    customers to use electricity more efficiently. Various factors such as increasing economic

    activity and population growth are resulting in additional pressure on ever increasing power

    demand when the country is already facing power shortage. In such a scenario, DSM can

    complement supply-side strategies to help meet electric service demands by assisting utilities

    avoid or delay costly capacity additions by slowing demand growth. To promote DSM, theGovernment is continuously introducing various policies and programmes targeting different

    sectors such as appliances, buildings, industries, etc. Despite these policies, the potential

    remains largely unrealized due to various technical, financial, economic, and institutional

    barriers.

    DSM is a concept in which a power utility, such as an unbundled distribution utility, manages

    the demand for power among some or all its customers to meet its current or future needs.

    DSM is either implemented directly through utility sponsored programs or through market

    intermediaries like ESCOs. In India, DSM can be achieved through energy efficiency, which is

    the reduction of kilowatt hours (kWh) of energy consumption or demand load management,

    which is the reduction of kilowatts (kW) of power demand or the displacement of demand to

    off-peak times. In the former category are programs such as awareness generation programs,

    customer or vendor rebates for efficient equipment, etc., while the latter includes time-of-use

    tariffs, interruptible tariffs, direct load control, etc. Specific types of programs depend on the

    utility objective: peak clipping, load shifting, strategic conservation or strategic load growth.

    Reductions in energy demand and consumption at the end users premises can free up

    electricity generation, transmission and distribution capacity at a fraction of the costs requiredto provide new capacity. The cost of saved energy has been estimated to be as low as 10% of

    the cost of added capacity for some DSM measures. In addition to avoided and deferred

    capacity costs, support for energy efficiency at its customers installations brings a utility into

    closer contact with its clients, often resulting in better service, and allowing a more efficient

    future planning process.

    This report aims at understanding the Demand Side Management (DSM) actions taken by the

    utility that influence the quantity or patterns of use of energy consumed by end users, such as

    actions targeting reduction of peak demand or reduction of energy consumed during periodswhen energy-supply systems are constrained. While, Peak demand management does not

    necessarily decrease total energy consumption but could be expected to reduce the need for

    investments in networks and/or power plants, the strategic conservation would lead to

    reduced energy consumption. Given the acute power shortage in the country and the recent

    collapse of the grid, it is imperative that the DSM program is carried out in a better and a more

    all-encompassing way than it is being done presently, we shall take a look at a couple of efforts

    that had been taken globally to arrest the rising inefficiencies in power transmission and

    distribution from the government as well as the consumers perspective. This is to bring to

    notice what all various kinds of measures that can be undertaken by the powergeneration/transmission/distribution/regulation institutions in the country for proper

    implementation of the DSM techniques.

    The benefits from the DSM initiatives are numerous and continue well ahead even when the

    initiatives are consciously stopped:

    Reductions in customer energy bills

    Reductions in the need for new power plant, transmission and distribution

    networks

    Stimulation of economic development

    Creation of long-term jobs due to new innovations and technologies. Increases in the competitiveness of local enterprises.

    Reduction in air pollution

    Reduced dependency on foreign energy sources.

    Reductions in peak power prices for electricity.

    EXISTING SITUATION AND

    PROJECTIONS

    For long electricity has been considered as a public good instead of a commodity, the first task at handthus becomes, acceptance of the underlying assumption that electricity should be viewed as a

    commodity instead of a public good, the principle stated above is equally applicable to electricity.

    When consumers do not see the real cost of electricity in their power bills, they over consume energy,

    and that misdirects excessive capital and fuel resources to the power sector. This is especially true

    during peak periods, when the cost of producing electricity is much higher than during the off-peak

    periods, largely because electricity cannot be stored in large quantities economically due to

    technological reasons.

    DSM is an umbrella term that includes several different load shape objectives, including load

    management (LM), energy efficiency (EE) and electrification. The load curve can be changed if DSMmeasures are followed, the diagram below shows what can be done through DSM initiatives.

    DSM in the Agricultural SectorThe agriculture sector in India uses 85% of the available fresh water. However, on-farm

    irrigation efficiency is only 20-50%. The other 50-80% is wasted. Combining these data indicate

    that the agricultural sector in India is wasting from about one half of the countrys total fresh

    water supply.

    On the energy front there are inefficiencies as well. The agricultural sector, on the average,

    accounts for about 30% of the total electricity consumption in India. The figure is somewhat

    higher in the agricultural states like AP, Gujarat, MP, UP, Karnataka, Haryana, etc. where

    agricultural electricity use is between 35-45%. However from a revenue perspective, the sale

    of this electricity amounts to no more than 5-10% of the state electricity boards revenues. The

    reason for this perverse state of financial affairs is the adoption of flat rate pricing for

    agricultural power. Under this system, when a farmer pays a fixed price per horse power per

    month for electricity, or what is termed as a flat-rate system, the marginal cost of pumping

    water is zero. This leads to energy wastages, over pumping and inefficient selection of crops.

    Moreover flat rate pumping masks the true cost of power to farmers. When unreliability is

    factored in, most farmers incur costs of Rs. 2-3/unit more than what typical urban dwellers

    pay. From a political-economic perspective, the flat rate structure enables the state to give the

    impression of providing subsidized power to the rural voting population whether or not thatpopulation actually receives the intended subsidy.

    Summing up, the tariff structure and the poor combination of technology and management are

    responsible for water loss, unsustainable exploitation of ground water and the high energy

    losses associated with the distribution and end-use of electricity in irrigation water pumping.

    Board of Energy EfficiencyIn the year 2001, the Energy Conservation Act, 2001 was passed which led to the set-up of the BEE

    (Bureau of Energy Efficiency), whose tasks were to make the following a mandate:

    Standards and labelling for appliances

    Energy Conservation Building Codes

    Energy consumption norms for Designated Consumers

    Certification and accreditation of energy auditors and energy managers

    for incandescent bulbs in households.

    Standards & Labelling Scheme targets high energy end use equipment and appliances to

    lay down minimum energy performance standards.

    Energy Conservation Building Code (ECBC) sets minimum energy performance standards

    for new commercial buildings.

    Agricultural and Municipal DSM targeting replacement of inefficient pump-sets, street

    CRITICAL ANALYSIS OF ISSUES

    The way forward is clear; Government should begin their liberalization program by focusing on

    pricing reform. People in all countries do respond to price signals. It is also to be kept in mind

    that the restructuring and commercialization activities of the utilities should be designed tomaximize the opportunity of sending cost-reflective price signals to customers and there should

    be a premium on price stability over economic efficiency.

    Large DSM expenditures on energy efficiency and conservation programs were resulting in

    revenue losses to the utilities. These concerns were justified, since DSM spending was lowering

    sales but the utilities had to cover their fixed costs regardless of the amount of electricity that

    was sold. Several decoupling mechanisms were devised to make the utilities whole by

    ensuring that they would recover their revenue requirement regardless of the amount of

    power sold. In other words, recognizing that utilities had large fixed costs, the mechanismswould ensure that sufficient revenues would be collected to cover these fixed costs, even if

    sales went down.

    CRITICAL ISSUES FOR INDIA

    Actual savings often fall short of projections, creating a credibility problem for new

    programs.

    Free riders often join the program and are paid incentives even though they would have

    taken the same actions (e.g., purchase an efficient light bulb or air conditioner) even inthe absence of the program.

    Program costs often exceed expectations, rendering the programs cost-ineffective.

    Utilities will not implement DSM programs without an assurance of cost recovery, the

    availability of sales-revenue decoupling mechanisms and financial incentives for

    shareholders.

    In many situations, standards for appliances (STAR Rating) and building codes (Green

    Buildings) may be the cheapest way to achieve long term efficiency gains.

    PARAMETERS TO BE CONSIDERED

    Targeting customer groups for a Phased Implementation

    Differentiating quotas and establishing criteria for differentiation among industrial

    customers

    Trading quotas in the marketplace

    Establishing quotas for distribution utilities

    Nature of incentives and penaltiesshould threat of disconnection be used to enforce

    quotas?

    and objectives.

    Management response, under emergency to curb the shortage of power. Thus this was when

    they undertook these measures.

    A traditional air-conditioner functions by absorbing heat from the room and expelling it into

    the environment. It uses more power when the outdoor temperature is high (say, 45-49

    degrees centigrade) and less when the outdoor temperature is lower (for instance, in

    September or October).

    This effect is put to use by new geothermal based air-conditioning systems to enhance

    efficiencies of traditional AC systems by more than 60%. The geothermal based system makes

    use of the ground (or the soil) to generate cooling for the air-conditioning equipment

    throughout the year, thus saving energy required for operating ACs. In fact, a geothermal

    system can help cut your power bill by as much as 80%.

    CLOSED CIRCUIT SOLAR WATER HEATERS

    In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above

    the solar collectors on the roof. No pumping is required as the hot water naturally rises into the

    tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground- or

    floor-mounted and is below the level of the collectors; a circulating pump moves water or heat

    transfer fluid between the tank and the collectors. This reduces the energy consumed from

    geysers.

    CONCLUSION/RECOMMENDATIONS The Governments, including the Ministry of Energy and appropriate Electricity Regulatory

    Commissions, should reform rate design, encouraging consumers to shift their usage to less

    expensive periods. They should reform the rate level, encouraging consumer to use less

    electricity if initially rates were lower than average costs, as they are in most developing

    economies. DSM programs should employ market pull strategies. It is important to create a

    self-sustaining process involving all members of the value chain, including the equipment

    manufacturer, wholesaler, retailer, installation and maintenance contractors and the end use

    customer. This process helps to transform the market infrastructure and is often referred to asmarket transformation.

    We felt that the Demand Side Management involves actions at the level of consumers which

    would ultimately depend upon numerous factors. These recommendations therefore focus on

    the necessary regulatory interventions which have to be primarily in the areas of appropriate

    pricing of electricity and enabling regulatory framework for consumer-utilities partnership.

    Operational issues should be responsibility of the utilities.

    The Forum of Regulators should organize training courses in the area of DSM forcapacity building of the personnel of the SERCs, the staff of DSM, Cells of the utilities in

    which the representatives of the State Governments may also be invited.

    The SERCs could also consider giving a slightly higher return on equity for the

    investments made towards DSM measures.

    The Bureau of Energy Efficiency (BEE) must follow-up with its various programs that

    have been launched and check the status of the same. BEE needs to be given more

    teeth.

    same.

    Since energy savings from S&L products are market transformation related , it is
