Over View of TNEB

The Tamil Nadu Electricity Board (TNEB) is a statutory body formed on 01.07.1957 under the Electricity Supply Act, 1948 as a successor to the erstwhile Electricity Department of the Government of Madras.

Generation

Starting with the modest installed capacity of 156 MW (Mega Watt) with annual gross generation plus purchase of 630 MU (Million Units) at the dawn of independence, the TNEB has grown by leaps and bounds with generating capacity of 7203 MW as on 31.3.2000 comprising 2970 MW from four Thermal Stations, 130 MW from two Gas Turbine Stations, 1995 MW from 32 Hydro Stations, 19 MW from Wind Farms and 1893 MW as Tamil Nadu’s share from Central Generating Stations. Generation from privately owned wind farms is 751.38 MW and TNEB’s wind farm generation is 19.355 MW. The Board’s gross generation during the year 1999-2000 was 38,313 MU. The total energy consumption during the same year was 30,090 MU.

Transmission

The transmission wing of the TNEB is headed by Chief Engineer/ Transmission at Chennai - 2, with 5 circles headed by SEs/GCC at Chennai, Salem, Coimbatore, Trichy and Madurai. Click Here For an Overview of Transmission Wing

Distribution

TNEB has 133.30 lakh consumers. The distribution network comprises 1,36,883 circuit kilometers of extra high tension (above 33 KV) and high tension (11 KV to 33 KV) lines, 4,15,000 circuit kilometers of low tension lines, 876 substations, 1,29,554 distribution transformers besides other assets.

The State continues to be in the forefront in the field of rural electrification in the country. As on 31.03.2000, all the 15,822 inhabitant villages have been electrified. In addition, 16,79,000 agricultural pumpsets and 15.19 lakh huts have been given electric supply. The role of Tamil Nadu Electricity Board in improving the economy of the State of Tamil Nadu by extensive electrification of the villages, large scale energisation of agricultural pumpsets and extension of electricity services to poor/backward and downtrodden sections of the society, in addition to extension of supply to large number of industries has been well recognised.

Staff of TNEB will be on call 24 hours, 7 days a week to respond to service emergencies. Fuse off call centres have been established in Chennai and Coimbatore and equipped with wireless sets in order to respond with the least delay. A control room manned round the clock also functions at the headquarters to register complaints.

Our commitment to excellence would include a continuous effort to modernise and upgrade not only our tools, plants and machinery but also our most valuable performing assets viz. our human resources.

Service Standards

We are committed to render the highest standards of service to you. This charter sets out the standards for the various services so as to improve our service to you. It is worth mentioning that these service levels are our maximum response times for important aspects of your electricity service, and that we aim to beat these standards every time we can.

Supply Break Down

Even with the best will in the world, faults will sometimes occur in our electricity networks and you may be without supply. If this happens, please let us know immediately. We’ll do everything possible to restore your supply quickly. Our aim is to restore supply within one hour in the case of EHT/HT supply in Chennai or 3 hours in mofussil areas. For failure of supply in pillar boxes or transformer structures causing interruption of supply to a group of LT service connections, we’ll restore supply in 2 hours in both Chennai and mofussil areas. The response time will be 3 hours in Chennai and 6 hours in other areas for individual consumers.

If you lose supply but notice that your neighbours still have power, the first thing to do is to check your own fuses and trip switch. If they are in order, then it could be that the EB fuse has failed. Please contact us immediately. We’ll call on you, free of charge.

When the distribution transformer which feeds your premises fail, we’ll replace it within 24 hours in Chennai or 48 hours in mofussil areas. In the case of very short supply interruptions and interruptions arising from network faults, we’ll make every effort to minimize the inconvenience to you.

In exceptional cases, such as cyclones or floods we cannot offer these standards. But we’ll always do everything we can to restore supply as soon as possible

Planned Supply Interruption

In our efforts to supply the best possible service, we often have to work on our distribution network to improve it or to connect new consumers. This may result in interruption of your electricity supply. When such interruption is necessary, we’ll inform you in advance by publishing it in newspapers.

Billing and Accounting

Should you have any query on billing or accounting, please contact the Revenue Branch of the Division concerned on all working days between 10.30 a.m. and 5.00 p.m. We’ll be able to give solution across the table in most of the cases. For cases where further investigation needs to be made, we’ll contact our field officers and send you the reply.

Meter Accuracy



If you think your energy meter is reading incorrectly, please contact us. We’ll replace the meter within 15 days of payment of challenge test in Chennai. For other places, it will be 30 days. We’ll revise the bills for the past period and adjust the excess amount, if any, in future bills, if the meter is found to be defective after test.

When we find that your energy meter is defective, we’ll replace it within 30 days in Chennai and 60 days in other places.

When the energy meter is burnt due to some reason or the other, we’ll replace it within 30 days.

Re-Connecting Supply

In some instances, we reluctantly have to withdraw supply for non payment of electricity charges. Once you have paid the bill along with arrears, if any, we’ll reconnect supply on the same day or the next day.

5. General Conditions For Captive Power Generation :

A. For Any Capacity :

(i) The energy generated from captive power plant has to be consumed by the owner himself scheme is operative only when Government declares power cut on consumption on electricity and quota to individual consumers is fixed by TNEB.

When a consumer uses power, out of his captive power generation and as a result



saves part (or full) energy in units out of the quota fixed to him for a particular month, he can bank such saved energy with TNEB in his account. When the energy saved out of the quota is higher than that generated by captive power, for any particular month, then banking shall be limited to the units generated by captive power generator.

The banking period is one year from 1st October to the next 30th September. The energy banked during a particular banking period shall have to be drawn during banking period or during the succeeding year banking period. For example, the energy banked from the 1st October, 1997 to the 30th September 1998 shall have to be drawn during any part of the years from 1st October, 1997 to 30th September, 1999. The balance of energy not drawn upto 30th September, 1999 out of the energy banked during the period from 1st October, 1997 to 30th September, 1998 shall automatically gets lapsed on 30th September, 1999 to TNEB.

(v) Wheeling shall be 15% in terms of energy wheeled in units irrespective of voltage or distance.

(vi) The cost of interfacing lines, switchgear, metering and protection arrangement shall have to be borne by the owner of captive power generators, but the work will be executed by TNEB on Deposit contribution Work basis.

(vii) When the owner of the captive power generator happens to be a consumer and when the power fed to the TNEB grid is less than 2 MVA, dedicated line from the location of the captive power generator to near by TNEB substation will not be required. The service line itself will cater to the need to export the power to the TNEB grid.

(viii) When the owner of the captive power generator happens to be a consumer and when the power fed to the TNEB Grid is more than 2 MVA, then a dedicated feeder to a nearby substation will be required. If already the consumer is availing himself of supply through a dedicated feeder and if the capacity of the feeder is adequate to carry the quantum of export of power, then the sance feeder can be used for export of power and no additional installation is required.

(ix) In case the dedicated feeder is not adequate to carry the power exported, then the existing dedicated feeder has to be strengthened or a new line has to be erected.

(x) For a non-consumer (user) the new interfacing line of appropriate capacity and voltage shall be at his cost and will be executed by TNEB.

8. Metering Arrangements :

In addition to the existing metering arrangements available for the service, separate electronic tri-vector meter with TOD provision will be provided for measurement of balance exported power.

9. Location of The Export Meter :

(a) Where a dedicated feeder is available

(i) If the balance energy is only for wheeling, the export meter will be at Captive Power Generation end. If the balance energy is partly for wheeling and partly for sale to Tamil Nadu Electricity Board, then the Captive Power Plant Owner may opt to have the Export meter either at Tamil Nadu Electricity Board’s receiving end or at Captive Power Generation end.

(ii) If the balance energy is only for sale to TNEB, the export meter will be at TNEB’s receiving end. For surplus power upto 2 MVA, where there is no dedicated feeder the export meter will be at Captive Power Generation end along with import meter.



(b) In cases where a dedicated line is not available, the export meter will be at Captive Power Generation end whether the power is wheeled or sold to TNEB.

(c) When the owner of Captive Power Generation is not a consumer, the export meter will be at TNEB’s receiving end and a reverse power relay will be connected so as to prevent drawal of power from TNEB Grid by the Captive Power Generation whenever there is no generation.

(d) The cost of providing the above metering arrangement shall be borne by the owner of the Captive Power Generators.

10. Wheeling Rules :

Prior approval of Chairman, TNEB has to be obtained for wheeling of power.Wheeling will be done to any service (H.T. or L.T) in Tamil Nadu with a fixed wheeling charge at 15% in terms of energy in units irrespective of the distance and voltage of the service for which wheeling is done. For sale of power, if the meter is at Captive Power Generation end, then 2% of the energy fed will be deducted for the loss in the interfacing line. The units of energy wheeled will be adjusted in the service for which wheeling is done as follows :-

(i) If the tariff of the service to which wheeling of energy is H.T. Tariff-I, the wheeled units will be directly adjusted.

(ii) If the tariff rate for the energy of the wheeled service is higher than that of H.T.Tariff-I, the adjustment will be at H.T. Tariff-I rate. The difference in rates will be charged to the consumer for the units wheeled.

(iii) (iii) If the tariff rate of energy of the wheeled service is lower than that of H.T. Tariff-I, then the wheeled units will be directly adjusted.

11. Pricing Of The Balance Power Sold To TNEB :

(i) The pricing for the Captive Power Generation is only single part, i.e. rate for units alone.

(ii) The rate for FIRM Power is at normal rate and the rate for INFIRM Power is at 75% of the normal rate.

(iii) FIRM Power means quantity of power in units committed by the owner of the Captive Generation to be sold to Tamil Nadu Electricity Board annually.

(iv) INFIRM power means quantity of power in units sold to TNEB, without any commitment or the entire quantity of power in units sold to TNEB, in case the commitment is not fulfilled.

(v) The rate for firm power for the year 1998-99 will be Rs.2.25 (Rupees Two and paise twenty five only). For the next 9 years there will be an increase of 5% (five percent) every year on the previous year rate. From 1-4-2008, the rate will be fixed after review.

12. Billing Methods



(i) Separate billing will be carried out for export and import of power by the Captive Power Generation. Import power will be billed according to the Tariff notifications of Government of Tamil Nadu from time to time.

(ii) Export billing will be done for the units exported as follows :-

(a) For Firm Power :

Annual commitment of firm power is for the twelve billing months from April to March. The monthly proportionate units will be worked out based on the annual commitment. The energy in terms of units fed into the grid for sale to TNEB during any billing month shall be between 5% and 11.66% of the annual commitment of power in terms of units except for the forced and planned shut down periods of the Captive Generations. If the export of power in any billing month is less than the proportionate monthly commitment, billing for that month will be done at infirm power rate. If the export is equal or in excess of the proportionate monthly commitment, billing for that month will be done at firm power rate. If the total export for 12 billing months from April to March is equal or in excess of the annual commitment, entire power will be billed under firm rate and the difference in billing at infirm rate already done will be revised in the March bill. If the total power sold during the year is below the annual commitment, the rate for infirm power will be charged in the same proportion of the shortfall in the units supplied as the proportion of shortfall in the commitment.

Example :

Committed Power : 100 unitsSupplied Power : 90 unitsShortfall in commitment : 10%

Out of 90 units supplied, only 10% of 90 units (i.e. 9 units) will be billed as infirm power and the balance (81 units) as firm power. Any consequent adjustment that may be necessary, shall be made in the bills for the month of March and, if necessary, in subsequent months.

(B) Infirm Power Will Always Be Billed At Infirm Power Rate :

13. Payment

(i) If the import bill amount is higher than the export bill amount the consumer has to pay the difference within the due date prescribed under Tariff Notifications. If the above amount is not paid within the date, the supply in the line will be cut off until he pays the amount with BPSC. No export or import of power is allowed during the cut off period.

(ii) If the export bill amount is higher, the difference will be paid by TNEB within the due date as per PPA.

14. Banking Facility Under Power Feed Scheme :

There is no banking facility under Power Feed Scheme for non-power cut period.



Accounts will be closed every month except for cases where wheeling is done to the service in other distribution circles for which one more month is allowed for adjustment.

During power cut periods, banking facility is allowed for 3 months. Banked energy should be withdrawn before the end of third succeeding month. For example, energy banked upto 31st March should be withdrawn before 30th of June of the same year. Energy not withdrawn during the above period will automatically lapse. Wheeling from banked energy to sister concerns is also permissible on the same condition.

The banking commission is 2% on the entire banked energy in terms of units.

15. General :

(i) Power export to TNEB will be at 0.9 Power Factor. If the average Power Factor of the export meter is below 0.9 penal levy will be made in the bill amount as prescribed in Tariff notifications for H.T. Services.

(ii) Individual PPA shall be executed with TNEB for purchase of power by TNEB. Prior permission has to be obtained from TNEB for wheeling. The Power Purchase Agreement will be for a period of 15 years or the expected useful life of the plant whichever is less.

(iii) All metering arrangements and protection system will be tested annually by TNEB and defect if any will be set right on cost basis. The cost of annual testing of the metering and protection system, to be charged to the consumer will be as follows :

(b) For those who are under Banking Scheme alone Rs.1500/- per annum.

(c) For those who are under Power Feed Scheme Rs.3000/-

These charges will be included in the monthly bill for that month in which the testing was carried out.

16. In case, the Tamil Nadu Electricity Board is not purchasing the balance Power i.e, firm power committed by the owner of the captive power plant due to reasons other than force-majeure conditions, then the owner of the captive plant will be allowed to wheel the quantum of power that is not purchased by the Tamil Nadu Electricity Board out of the annual commitment by the captive power plant owner to third parties with certain conditions imposed by Tamil Nadu Electricity Board. The rate charged by the captive power plant operator for such third party sales shall not be less than the tariff charged by Tamil Nadu Electricity Board to that class of consumers.

17. In case of disputes, these will be settled by mutual discussion.

18. Without prejudice to other rights of the Board and the Government of Tamil Nadu, the Board and Government have the right to relax, modify or delete any of the above policy guideline on Captive Power Generation at any time.

2.0 Electrical Safety

A Downed Power Line Electric Safety in Home Beware the Substation<O:P</O:P Coping with a Power Outage<O:P</O:P

2.1. Downed Power Line

No matter how well our Electricity Board is prepared, downed power lines cannot be avoided. Trees can fall, taking several lines down with them. A vehicle could spin out and break a pole bringing down several lines. If a downed power line is spotted, stay away from it. Immediately call at the emergency numbers of TNEB. They will repair it and restore power as quickly as possible if it is Rain or shine, day or night.



2.2. Electric Safety in Home

Please Don't Go Near the Water.

Not with the hair dryer, power tools, the radio, toaster or any appliance. This can be used in the kitchen, bathroom, laundry room or work shed.

Can’t be taken for granted, and it's easy to forget that water and electricity must never mix.

So appliances should not be used when you're in the bathtub or shower, or let an electric cord trail near the kitchen sink or anywhere in the laundry room or garage where water might collect.

Look around you. Make sure it's safe to go near the water. Just a few seconds of caution can make a big difference.

Make Home Safe for Children

When babies start crawling, they love to get around and investigate everything.

Childproof your home against electrical hazards. Outlets are fascinating to babies. Keep them from sticking anything into outlets by installing plastic protective caps.

When bathing your child, make sure all nearby appliances are unplugged. Electricity and water can be a deadly combination. Make sure electrical cords aren't frayed or cracked. Keep them out of the reach of wet hands and mouths.

Curiosity in a baby is a wonderful thing...so keep it safe.

2.3 Beware the Sub-Station & Transmission Lines

Be careful to avoid electrical sub-stations. The sub-station is the place where huge amounts of electricity are reduced to lower voltage and distributed to homes.

The fence surrounding the substation has barbed wire on top and a sign warning: "DANGER -- HIGH VOLTAGE" The sign is there for safety. Stay clear of it.

Similarly avoid such sign warning in Poles, Towers and Structures.



2.4 Coping with a Power Outage

TNEB strives to keep the power on for every home and business in our service territory; however, unexpected conditions can cause a temporary power outage.

2.4.1 If the power goes off...

Confirm the outage by first checking lights and appliances in other rooms. If you still have power in some areas, most likely a fuse has blown or a circuit breaker has opened. This could be a warning of overloaded wiring or a defective appliance. If all lights are off, check to see if neighbors' lights are also off. This will help to determine how widespread the outage is.

Call the EB to report the outage at the nearest telephone numbers. Outage is recorded on each reporting. This information, along with information received from other members, is entered into the Register, which when compiles the information and summarizes the outage pattern. This summarization helps our personnel to pinpoint the trouble areas, which will then allow to efficiently dispatch the repair crews.

Protect the appliances by turning off all large appliances that come on automatically. Make sure to shut off the water heater, air conditioner, water pump, and refrigerator. This will prevent overloading electrical circuits when power is restored. Disconnect all sensitive appliances such as VCRs, Audio record Players, Computers, TVs, Microwave ovens, etc., to avoid damage from lighting or a power surge. Turn off any appliances, which were operated before the power outage occurred.

If the outage appears to be for an extended period of time -- open the freezer and refrigerator as little as possible. Food will stay fresh longer if the doors are not opened. A full freezer will keep food frozen for 24 to 48 hours.

If you use a standby generator, be sure it has been installed and wire properly with a double-throw switch. This will prevent electricity from flowing to the outside lines and possibly injuring you, your neighbors or utility crews.

2.4.2 Plan ahead and be Prepared…

Always keep an alternate source of light on hand such as a flashlight with extra batteries, candles with matches, or a kerosene, propane, or oil lamp with the appropriate fuel

Keep emergency food and related items on hand such as nonperishable foods that require no cooking, canned fruit, powdered milk, peanut butter and crackers



2.4.3 When the Power Comes back on...

When the power first comes back on, turn on only the most essential appliances and wait 10-15 minutes before reconnecting the others

Check food supplies for signs of spoilage. Don't take a chance on food you are not sure about. It is better to throw it away and be safe than to keep it and be sorry.

Before switching back to the normal heat/cool setting, check the outdoor unit to assure it is free from brush or leaves.

2.4.4 TNEB 's Restoration Plan

Our restoration plan is to make repairs that will restore service to the most members in the least amount of time. The power must be restored in the sequence shown below because individual services cannot receive electricity until all previous steps are completed.

Restoration Steps:

(a) Transmission lines -- these supply power to one or more substations, and could cause an outage for several lakhs of consumers.

(b) Sub-Stations -- depending on the location, a substation outage could affect over a lakh of consumers.

(c) Main Feeders -- each feeder serves a portion of thousands of consumers or a lot of Distribution Transformers from each substation.

(d) Distribution Transformers / Pillar Boxes -- these serve smallergroups of consumers from the main feeders.

(e) Individual Services -- these are lines / cables that serve single residences / sites.

3.0 Conservation of Energy in Home

3.1 Lighting

Turn off lights in empty rooms.

Use fluorescent lights when possible.

Reduce high wattage bulbs where less light is needed.



3.2 Kitchen Appliances:

3.2.1 Refrigerator:

Open refrigerator door only when necessary. Know what you are looking for before opening the freezer or refrigerator door.

To keep your refrigerator running efficiently clean the refrigerator coils. Vacuum or dust the cooling coils on the bottom or back regularly. Make sure these coils are at least four inches from the wall so that the coils can have room to breathe. In addition, do not place your refrigerator near any heat source such as your oven, heat vent, etc.

Adjustable shelves can help you use space efficiently. Special storage compartments keep meats, fruits and vegetables at the right temperature.

Cover all food before putting in refrigerator.

Check door seal yearly to be sure it seals tightly.

3.2.2 Oven, Microwave and small appliances:

Use pots that fit the range cooking unit; cover pans and use little water. Keep range top clean and reflectors shiny.

Cook many foods in the oven at the same time or make extra portions for future meals. Arrange dishes in oven for good air flow. Don't line racks with foil.

Use small appliances and microwave as much as possible. Microwaves, electric frying pans, toaster ovens and outdoor grills are often quicker and more economical to use than an electric range.

Serve cold cuts and salads for a change. Automatic cleaning systems help keep ovens clean and efficient. Use self-

cleaning system while oven is still hot from baking.

Don't preheat oven unless recipe calls for it. Keep oven door closed during baking.

Defrost foods in refrigerator whenever possible. Quick defrosting can save valuable time but uses energy.

Keep microwave clean so all the heat is concentrated on the food, not the spills.



3.2.3 Utility Room Appliances

Wash full loads; but never overload.

Clean lint filter on dryer after use.

Iron a number of items at one time while iron is hot.

Line dry clothes when possible.

Remove clothes that need ironing from dryer when damp.

Adjustable water levels can save money on water use.

Locate washer near the water heater to minimize heat loss through pipes.

Presoak heavily soiled laundry when possible.

Dry two loads in a row to use the heat still in the dryer from the first load.

3.2.4 Water Heating

Lower water heater temperature to around 120 degrees if you don't have a dishwasher.

Use warm water wash and cold water rinse when laundering.

Fill bathtub only 1/4 full when bathing. Take quick showers instead of baths to save water.

Add insulation to an older water heater to save energy and money.

Wash dishes in a full sink, not under running water.
