Section 410.190  Meter Tests Requested by Customer

 

a)         Upon customer request, the entity providing metering service to that customer shall test the customer's meter within 30 days after receiving the request, unless the customer agrees to a later time. The meter test shall be performed between 7 a.m. and 4 p.m. Monday through Friday, excluding holidays, unless some other time is agreed upon by the entity and the customer.  The test shall be performed at the meter installation location and in the customer's presence, unless the customer gives consent for the meter to be removed and/or tested outside the customer's presence.

 

b)         If the customer's meter has been tested at the request of another entity or customer while in service at the same location within the past 6 months, the entity may provide the results of that test in reply to the customer's request in lieu of the test specified in subsection (a).

 

c)         An entity shall not require any payment from the customer for a meter test, unless a test has been performed on that meter at that customer's request within the previous 12 months, or information has been provided as in subsection (b) within the past 6 months. In such cases, the customer shall be required to pay $40 to the entity.  The entity shall refund the $40 deposit to the customer if the entity finds that the meter over-registers by more than 2%.

 

d)         Commission referee tests

 

1)         Upon written application to the Commission by any customer, the entity providing metering service shall test the customer's meter within 30 days after receiving notice of the written request from a Commission representative, unless the customer agrees to a later time. The application for a Commission referee test shall be accompanied by a fee of $20. The entity shall conduct this test under the supervision of a representative of the Commission.

 

2)         On receipt of the request from a customer, a Commission representative shall notify the entity. After the entity has received notice that application has been made for a referee test, the entity shall not disturb the meter in any way, unless the customer or the Commission gives written permission for the meter to be removed.

 

3)         The entity shall furnish to the Commission's representative such assistance as may be required to make the test. The Commission shall make a written report of the results of the test to the customer within 30 days after the test.

 

4)         If upon test the meter is found to over-register by more than 2%, the entity shall reimburse the customer the amount paid to the Commission for the test. The entity shall also make any necessary metering data adjustment.

 

e)         No entity shall be required to perform more than 2 tests of the same meter installed at the same location at customer request within a 12 month period, unless a Commission referee test is requested. After a Commission referee test, the entity shall not be required to test the same meter for a period of at least 12 months.

 

Section 410.195  Meter Tests Requested by Entity

 

a)         Upon another interested entity's request, the entity providing metering service shall test the meter within 30 days after receiving the request, unless the requesting entity agrees to a later time. The meter test shall be performed between 7 a.m. and 4 p.m. Monday through Friday, excluding holidays, unless some other time is agreed upon by the entities.  The test shall be performed at the meter installation location and in the presence of a representative of the requesting entity, unless the requesting entity gives consent for the meter to be removed and/or tested without the representative's presence.

 

b)         If the meter has been tested at the request of another party while in service at the same location within the past 6 months, the entity may provide the results of that test in reply to the entity's request in lieu of the test specified in subsection (a).

 

c)         Meter tests requested by other entities may be performed at any time agreeable to both entities if the customer's electrical service will not be interrupted by the test. If the customer's electrical service will be interrupted by the test, the testing entity or requesting entity shall obtain permission from the affected customer to interrupt the service before the test is performed.

 

d)         The entity requesting the meter test shall be required to pay the actual cost (not to exceed $250) of performing the test to the entity performing the test. The entity performing the test shall refund the payment to the other entity if the meter over-registers by more than 2%.  No entity shall induce a customer to request a meter test on behalf of that entity to avoid paying the actual cost of the meter test.

 

e)         The entity providing metering service shall not be required to provide more than 1 test on the same meter at the same location more than once every 3 years at the request of another entity, unless the other entity requests a Commission referee test.

 

f)         If an entity requests a Commission referee test, the requesting entity shall pay $20 to the Commission and the actual cost (not to exceed $250) of the test to the entity providing metering service. If the meter over-registers by more than 2%, the entity providing metering service shall refund both fees to the requesting entity and make any necessary meter data adjustment. The entity providing metering service shall not be required to provide a Commission referee test on the same meter at the same location more than once every 12 months.

SUBPART C: CUSTOMER INFORMATION

 

Section 410.200  Corrections and Adjustments for Meter Error

 

a)         Whenever any test made by any entity or by the Commission shows a meter to have an average error of more than 2%, a correction of the metering data shall be determined by the entity providing metering service and that correction shall be conveyed within 3 business days to the customer and to other entities involved in billing the customer.

 

b)         When a meter is found to have an average error of more than 2%, the entity providing metering service shall determine the metering data correction using the actual percentage of error as determined by the test, not the difference between the allowable error and the error found as a result of a test.

 

c)         If the meter is found to run faster than allowable, the entity providing metering service shall determine the correction to the metering data for that meter. In determining the correction it shall be presumed, unless demonstrated otherwise, that the inaccuracy has existed for a period of 2 years. This period of presumed inaccuracy shall not exceed the time for which records of the current customer's usage exist.

 

d)         If the meter is found to be slower than allowable, the entity providing metering service shall determine the correction to the metering data for that meter. In determining the correction, it shall be presumed, unless demonstrated otherwise, that the inaccuracy has existed for a period of 1 year prior to the test for small commercial and residential customers and 2 years prior to the test for all other customers.

 

e)         In the case of a non-registering meter that has been read during the period of non-registration, the entity providing metering service shall not determine a correction to metering data for estimated consumption extending over more than twice the regular interval between readings.

 

f)         No corrections to metering data for meter error shall extend beyond the in-service date of the meter discovered to be in error, nor shall any correction be required to extend beyond the date upon which the current customer first occupied the premises at which the error is discovered.

 

g)         Whenever an entity or the Commission's representative finds that a service watt-hour meter, while in service, exhibits creep, the entity shall make an estimate of the registration caused by the creep during the period as specified under subsection (c) and shall make a corresponding correction in the metering data.

 

h)         Billing adjustments

 

1)         For electric utilities. Any correction to metering data for over-registration shall be accompanied by an adjustment to customer billing by any electric utility that rendered service that is affected during the period of adjustment. Corrections made to metering data for under-registration may be accompanied by an adjustment to a customer's billing. However, if an electric utility is providing metering service, in no case shall an adjustment to a customer's billing be made for under-registration if all testing and accuracy requirements of this Part have not been met.

 

2)         For entities other than electric utilities. Any correction to metering data made by any entity other than an electric utility and all records relating to the adjustment of the customer's billing or charges shall be retained for at least 2 years.

 

i)          Provisions of this Section do not apply to situations in which the customer's wires, meters or other service equipment have been tampered with and the customer enjoyed the benefit of the tampering.

 

Section 410.210  Information to Customers

 

a)         Bills rendered to retail customers for service shall clearly show at least the following:

 

1)         The date of the meter reading, the number of days in the billing period, the energy used, the meter constant if applicable, the type of service rendered, a complete description of the service or rate classification under which the customer receives service, and the type of reading that was used in the bill calculation (such as actual, estimated or customer reading), and, for meters for which beginning and ending meter readings are used as billing determinants, the reading of the meter at the beginning and the reading of the meter at the end of the period for which the bill is rendered.

 

2)         In the event that a bill rendered to retail customers is not based on usage derived from meter readings, the bill must indicate the period of time for which the bill is rendered, the type of service rendered, and a complete description of the service or rate classification under which the customer receives service.

 

3)         The total amount of the bill and, when applicable, the following portions that make it up, listed vertically for easy readability:

 

A)        the monthly customer charge or portion thereof;

 

B)        the demand charges;

 

C)        the cost of energy detailed by the energy used and the price per unit for each change in the unit price;

 

D)        the cost of fuel adjustment;

 

E)        any other applicable adjustments (other charges not under categories of charges but relating to services, energy, or other programs provided to customers by the entity);

 

F)         State tax;

 

G)        municipal tax;

 

H)        infrastructure maintenance fee;

 

I)         transition charge; and

5)         Definitions or explanations of any abbreviations and technical words used on the bill.

 

6)         The name and the toll-free telephone number of each service provider whose services to the customer appear on the bill.

 

7)         The average use per day for the period over which the bill is rendered and for the comparable period one year earlier, and an indication of the difference in temperatures between the two periods.  If this information is not available for a customer, the bill shall so state.

 

b)         Each entity, upon request by a customer, shall transmit at a minimum a statement of the actual consumption of energy by the customer at the customer's present billing address for each billing period during the immediately preceding 12-month period for which that customer was receiving service.

 

c)         All electric utilities shall have on file with the Commission a proposed tariff under Section 9-201 of the Act [220 ILCS 5/9-201] that contains a bill form complying with the requirements of subsection (a). By June 15, 2001, all billings shall comply with the requirements of subsection (a).

 

d)         As mandated by Section 8-302 of the Act [220 ILCS 5/8-302], whenever a customer for whom an electric utility provides metering service provides the utility with a written request asking the meter reader to leave a card showing these meter readings and dates, the electric utility shall have its meter reader leave a card showing these meter readings and dates.

 

e)         Each electric utility shall disclose to each of its customers information about the customer's service in a clear and concise manner. The disclosure shall contain the following minimum requirements:

 

1)         A description of the rates or charges for the rate classification under which the customer receives service;

 

2)         An identification and explanation of optional or experimental rates or classifications available to customers; and

 

3)         An identification and explanation of all charges that are not related to costs incurred in service and the supply of energy to that customer.

2)         To all affected customers in the event of a change in overall rate levels. The disclosure statement shall be transmitted, at a minimum, within the second complete billing cycle after the rates become effective following the issuance of a final order in any rate proceeding. If the disclosure is sent during a period in which proration occurs, a statement such as the following shall be incorporated in the text:

 

            "This summary is being sent during a period in which proration occurs. Proration occurs when part of your bill is charged on old rates and part of your bill is charged on new rates. If an attempt is made to calculate your bill using this rate summary, your calculation will not yield the proper billing amount for this billing period, but will do so in subsequent months. We recommend that you retain this summary for future reference in computing proper billing amounts."

 

h)         Each ARES shall provide to all residential and small commercial customers, at least annually, a disclosure statement with the following information:

 

1)         the average monthly prices; and

 

2)         the terms and conditions of the products and services sold to the customer.

 

i)          At least annually, each electric utility shall provide to small commercial and residential customers an identification and explanation of optional or experimental rates or classifications available to the customer.

SUBPART D: ELECTRIC SERVICE STANDARDS

 

Section 410.300  Voltage Regulation

 

a)         Standard voltage. Each entity supplying electrical energy for general use shall adopt a standard service voltage of 120 volts (when measured phase to neutral) and shall maintain the service voltage within the allowable variations from that value at all times.

 

b)         Allowable voltage variations. For service rendered at the standard service voltage, voltage variations as measured at any customer's point of delivery shall not exceed a maximum of 127 volts nor fall below a minimum of 113 volts for periods longer than two minutes in each instance.  For service rendered at voltages other than the standard voltage value, voltage variations as measured at any customer's point of delivery shall not exceed 10% above or below the service voltage for a longer period than two minutes in each instance.

 

c)         Variations of voltage in excess of those specified above shall not be considered a violation of this Section if caused:

 

1)         by operations of a retail customer in violation of an agreement with or the rules of the entity;

 

2)         by the operation of apparatus on a retail customer's premises that results in large inrush currents;

 

3)         by infrequent and unavoidable fluctuations of short duration due to system operation; or

 

4)         by acts of nature or other situations beyond the entity's control.

 

Section 410.310  Voltage Surveys  

 

a)         Each entity shall make voltage surveys of its system to keep itself informed regarding the character of the service being furnished from the system. Such surveys may be made by recording instruments, analytical methods, or a combination of these methods.

 

b)         All charts or readings taken or analyses made in voltage surveys shall be retained for at least 5 years and kept  in a systematic manner. The entity shall record the date, hour and place of the test, distance from the transformers, size of transformers, the instruments used, and the name of the persons making the test.

 

c)         For use in making voltage surveys, each entity shall provide portable recording voltmeters. These instruments shall be of a type and range suited to the voltage supplied.

 

d)         Each entity shall install and maintain recording voltmeters on its system to indicate the adequacy of voltage control methods and equipment.

 

Section 410.320  Standard Frequency

 

Each entity that supplies alternating current for use by retail customers in this State shall operate its equipment in a manner that the frequency of the alternating current maintained by the operation of the interconnected transmission systems is not degraded as a result of any action or lack of action on the part of the entity.

 

Section 410.330  Service Connections

 

An entity providing distribution services shall furnish and install without charge a service connection of reasonable length from the distribution system to the point of delivery on the customer's property, unless otherwise provided for in the utilities' tariffs.

SUBPART E: EXTENSION OF LINES

 

Section 410.400  Application of Subpart E

 

This Subpart shall not apply to applicants for auxiliary, standby or temporary service.  Each entity providing distribution services shall file line extension provisions with the Commission that set forth conditions and terms for provision of auxiliary, standby, or temporary service.

 

Section 410.410  Extension Provisions

 

a)         If an extension of a entity's distribution system is necessary in order to serve an applicant or group of applicants, the entity providing distribution services, upon written request for service by the applicants, shall make the necessary line extension. The line extension shall be made along a street, highway or other right-of-way to the nearest point adjacent to the point of delivery for the applicants. The applicant or group of applicants must agree to the provisions of this Section before the line extension is made.

 

1)         The entity providing distribution services may file a line extension provision in conjunction with its rate schedule. If the entity providing distribution services files a line extension provision, that provision shall be worded so that the applicant will have a choice of obtaining the extension under the provision or obtaining the extension under subsections (b) and (c). If the line extension provision is permitted to become effective by the Commission, then the applicant may proceed under the line extension provision or under subsections (b) and (c).

 

2)         Alternatively, the filed line extension provision may be in lieu of subsections (b) and (c) instead of an option; however, if the entity providing distribution services files a line extension provision in lieu of subsections (b) and (c), the line extension provision shall not become effective unless the entity providing distribution services demonstrates that the line extension provision is generally more favorable to applicants than the provisions of subsections (b) and (c). After specific action by the Commission by order, the line extension provision shall become effective.

 

b)         Free extensions

 

1)         If an extension of the entity's distribution system is necessary in order to serve an applicant or a group of applicants, the entity shall extend its line without charge for each applicant along the street, highway or other available right of way to the nearest point adjacent to the premises of the applicants, upon written request for service. If the entity believes the cost of providing the extension is excessive, the entity may file a request with the Commission for a modification of this requirement for a specific extension. The line extension furnished without charge shall be the cost equivalent of up to 250 feet of single-phase overhead line per customer and shall include any necessary delivery voltage transformer and its associated protective devices for each customer. No free extension shall be made from existing lines on which refunds are due from previous deposits. If a refund is due from a previous deposit, any further extension shall be made only upon the applicant making a deposit equal to the full estimated cost of the required additional extension.

 

2)         If all or part of a line extension is made on existing poles and costs less than the cost of constructing the free extension described in subsection (b)(1), the entity shall not charge for the extension.

 

c)         Extension in excess of the free limit

 

1)         If the cost of the line extension is greater than that allowed in subsection (b), the entity shall make the line extension and shall own, maintain, and replace the line extension upon agreement by the applicant or group of applicants to deposit with the entity an amount under the original or any subsequent extension, equal to the estimated cost of the extension above the free limits.

 

2)         The cost of extensions in excess of the free limit, and any resulting deposits, shall be allocated among customers based on their respective share of the length of the line extension. Deposits will be refundable based on changed circumstances or shared use for a period of ten years from the date the line extension is placed in service.

 

3)         In no case shall a refund exceed the original deposit.

 

4)         If the premises of a customer are so located that they could be served by extending a parallel separate line at less cost than the amount of deposit that would be required from them for connection to the existing extension, the customer shall not be required to deposit in excess of the estimated cost of the separate line.  The customer shall not share in any refunds so long as the deposit remains less than that of other depositors on the line extension.

 

5)         Combining of rural service. For the purposes of determination of the deposits and refunds, a farm applicant whose premises include a number of buildings such as barns, employees' houses, etc., for which electric service is desired may qualify as a single applicant, provided the farm applicant constructs the necessary facilities required to supply the various buildings from a mutually agreed upon point conveniently located near the entity's lines. This shall not be construed as including electric service to buildings occupied by a tenant who leases land or conducts a business separate from that of the land owner.

 

6)         In the event an option is available for a line extension to a group of applicants, the decision of the majority of the applicants will determine which option is implemented.

 

7)         Determination of deposit. The distance of the electrical equipment installation from the available primary or secondary circuit that is nearest to the route that normally would be used in making the extension that is on available right-of-way shall be considered in determining whether an applicant is entitled to a free extension, and the cost of extending this circuit shall be used as the basis in determining the amount of deposit necessary in case the extension is above the free limit.

 

d)         Commission review. If the extension is of such length and the prospective business that may be developed by it is so meager as to make it doubtful whether the business from the extension would ever pay a fair compensation for its investment, operation, maintenance and replacement, or for other substantial reasons is unwarranted, the fact shall be reported to the Commission for investigation and determination as to the reasonableness of the extension.
