(4.2) For the purposes of paragraph 1.1 of subsection (2), the peak demand factor of a Class A market participant that is an eligible cogeneration customer but not an eligible purchase customer in respect of the adjustment period is calculated to eight decimal places using the formula, (V – V.1) / W in which, “V” has the same meaning as in subsection (4), “V.1” is, subject to subsection (4.3), the volume of electricity physically supplied into the IESO-controlled grid by one or more cogeneration facilities during the peak hours in the applicable base period, pursuant to one or more cogeneration capacity agreements between the owners or operators of cogeneration facilities and the Class A market participant, and “W” has the same meaning as in subsection (4). O. Reg. 101/25, s. 5 (3). (4.3) The following rules apply for the purposes of determining the value of “V.1” in the formula set out in subsection (4.2): 1. If the value of “V.1” is greater than the value of “V” during a peak hour, the value of “V” shall be substituted for the value of “V.1” for that peak hour. 2. If the aggregate volume of electricity physically supplied into the IESO-controlled grid by one or more cogeneration facilities during a peak hour in the applicable base period pursuant to one or more cogeneration capacity agreements between the owners or operators of cogeneration facilities and the Class A market participant exceeds the aggregate volume of electricity withdrawn during that peak hour by the load facility or facilities of that Class A market participant to which the cogeneration capacity agreements relate, that excess volume shall not be included in determining “V.1”. 3. For the purposes of determining “V.1”, a volume of electricity shall only be included if the IESO is satisfied that the same volume of electricity was generated using capacity that is not the subject of a procurement contract entered into with the IESO or a capacity auction conducted by the IESO. 4. For the purposes of determining “V.1”, the IESO shall rely on, i. the information provided in the applicable cogeneration capacity agreement provided as described in section 10.7 to the IESO by the Class A market participant, and ii. such other information as the IESO may require under section 10.8 for the purposes of this subsection. O. Reg. 101/25, s. 5 (3). (4.4) For the purposes of paragraph 1.2 of subsection (2), the peak demand factor of a Class A market participant that is an eligible purchase customer but not an eligible cogeneration customer in respect of the adjustment period is calculated to eight decimal places using the formula, (V – V.2) / W in which, “V” has the same meaning as in subsection (4), “V.2” is, subject to subsection (4.5), the volume of eligible electricity physically supplied into the IESO-controlled grid or the distribution system of a licensed distributor during the peak hours in the applicable base period pursuant to any eligible purchase agreements entered into by the Class A market participant, and “W” has the same meaning as in subsection (4). O. Reg. 101/25, s. 5 (3). (4.5) The following rules apply for the purposes of determining the value of “V.2” in the formula set out in subsection (4.4): 1. If the aggregate volume of eligible electricity physically supplied into the IESO-controlled grid or the distribution system of a licensed distributor during a peak hour pursuant to any eligible purchase agreements entered into by the Class A market participant exceeds the aggregate volume of electricity withdrawn during that peak hour by the load facility or facilities to which the eligible purchase agreement relates, that excess volume shall not be included in determining “V.2”. 2. For the purposes of determining “V.2”, a volume of electricity shall only be included if the IESO is satisfied that, i. the volume of electricity is not compensated electricity, and ii. the requirements of clause 10.13 (1) (d) have been met throughout the applicable base period. 3. If any eligible purchase agreement used to determine “V.2” is amended or restated during a base period and the volume or proportion of eligible electricity contemplated in clause 10.13 (1) (d) is changed, then, for the purposes of determining “V.2” from and after the effective date of the amendment or restatement, the lesser of the volumes or proportions from before or after the change shall be used. 4. If the value of “V.2” is greater than the value of “V” during a peak hour, the value of “V” shall be substituted for the value of “V.2” for that peak hour. 5. For the purposes of determining “V.2”, the IESO shall rely on, i. the information set out in the applicable eligible purchase agreements provided to the IESO by the Class A market participant, and ii. such other documents and information as the IESO may require under paragraph 5 of subsection 10.10 (1) for the purposes of this subsection. O. Reg. 101/25, s. 5 (3). (4.6) For the purposes of paragraph 1.3 of subsection (2), the peak demand factor of a Class A market participant that is an eligible purchase customer and an eligible cogeneration customer in respect of the adjustment period is calculated to eight decimal places using the formula, (V – (V.1 + V.3)) / W in which, “V” has the same meaning as in subsection (4), “V.1” has, subject to subsection (4.7), the same meaning as in subsection (4.2), “V.3” is, subject to subsection (4.7), the volume of eligible electricity physically supplied into the IESO-controlled grid or the distribution system of a licensed distributor during the peak hours in the applicable base period pursuant to any eligible purchase agreements entered into by the Class A market participant, and “W” has the same meaning as in subsection (4). O. Reg. 101/25, s. 5 (3). (4.7) The following rules apply for the purposes of applying the formula set out in subsection (4.6): 1. If the aggregate volume of eligible electricity physically supplied into the IESO-controlled grid or the distribution system of a licensed distributor during a peak hour pursuant to any eligible purchase agreements entered into by the Class A market participant exceeds the aggregate volume of electricity withdrawn during that peak hour by the load facility or facilities to which the eligible purchase agreement relates, that excess volume shall not be included in determining “V.3”. 2. If any volume of electricity in “V.3” is also a volume of electricity in “V.1” during a peak hour, that volume shall not be included in determining the “V.3” for that peak hour. 3. If any eligible purchase agreement used to determine “V.3” is amended or restated during a base period and the volume or proportion of eligible electricity contemplated in clause 10.13 (1) (d) is changed, then, for the purposes of determining “V.3” from and after the effective date of the amendment or restatement, the lesser of the volumes or proportions from before or after the change shall be used. 4. If the value of the sum of “V.1” and “V.3” is greater than the value of “V” during a peak hour, the value of “V” shall be substituted for the value of the sum of “V.1” and “V.3” for that peak hour. 5. For the purposes of determining “V.3”, a volume of electricity shall only be included if the IESO is satisfied that, i. the volume of electricity is not compensated electricity, and ii. the requirements of clause 10.13 (1) (d) have been met throughout the applicable base period. 6. For the purposes of determining “V.3”, the IESO shall rely on, i. the information set out in the applicable eligible purchase agreements provided to the IESO by the Class A market participant, and ii. such other documents and information as the IESO may require under paragraph 5 of subsection 10.10 (1) for the purposes of this subsection.

If the transferee is a Class A market participant on the effective date, the IESO shall allocate to the transferee the amount determined by multiplying, i. the global adjustment for the month, ii. the transferee’s peak demand factor, as calculated on the effective date, and iii. the ratio of the number of days remaining in the month, including the effective date, to the total number of days in the month. 2. If subsection 8.1 (6) applies, the IESO shall allocate to the transferor, in addition to any amount allocated to them under subparagraph 1 iii of subsection 11 (2), the amount determined by multiplying, i. the global adjustment for the month, ii. the transferor’s peak demand factor, as calculated on the effective date, and iii. the ratio of the number of days remaining in the month, including the effective date, to the total number of days in the month. O. Reg. 257/22, s. 17. Adjustments by licensed distributors re Class B consumers 16. (1) This section applies to adjustments to be made by licensed distributors under subsection 25.33 (2) of the Act with respect to Class B consumers. O. Reg. 398/10, s. 6. (1.1) In this section, “low-volume consumer” means a low-volume consumer as defined in section 56 of the Ontario Energy Board Act, 1998; “specified Class B rate” means the Class B rate estimated or finally determined by the IESO that is used for the month by the licensed distributor in accordance with this section in respect of the Class B consumer. O. Reg. 311/13, s. 2 (1); O. Reg. 116/23, s. 5 (1). (2) In determining an adjustment under this section, a licensed distributor shall use, (a) the first estimate of the Class B rate for the month made by the IESO and published no later than the last business day of the previous month; (b) the second estimate of the Class B rate for the month made by the IESO and published no later than the last business day of the month; or (c) the Class B rate for the month as finally determined by the IESO. O. Reg. 398/10, s. 6. (3) If a licensed distributor chooses to use the estimate of a Class B rate described in clause (2) (a) or (b) in determining the amount to be allocated for a month to the account of a Class B consumer, it must do the following: 1. Use the same Class B rate in respect of all Class B consumers who are included in the same consumer class in an order issued by the Board under subsection 78 (2) of the Ontario Energy Board Act, 1998. 2. Establish and maintain, in accordance with any protocols established by the Board, such variance accounts as may be necessary to record all differences arising by reason of using the estimate of the Class B rate instead of the actual Class B rate as finally determined by the IESO. O. Reg. 398/10, s. 6. (4) Every licensed distributor shall make adjustments with respect to its Class B consumers who are not low-volume consumers in accordance with the following rules: 1. For each Class B consumer whose electricity use is measured by an interval meter and who is neither a regulated consumer nor a consumer who has a contract with a retailer who uses retailer-consolidated billing, the licensed distributor shall, i. for each month in the Class B consumer’s billing period, multiply the specified Class B rate for that month by the volume of electricity that was distributed to the Class B consumer by the licensed distributor in that month and subtract, in the case of a Class B consumer that is an electricity storage facility, the volume of electricity, if any, that was conveyed into the distribution system of the licensed distributor by the Class B consumer in that month, multiplied by the specified Class B rate for that month, ii. add the monthly amounts determined under subparagraph i for the billing period, and iii. adjust the invoice that the licensed distributor issues to the Class B consumer for the billing period by giving a credit for the amount determined under subparagraph ii if the amount is negative or by adding the amount determined under subparagraph ii as an additional charge if the amount is positive. 2. For each Class B consumer whose electricity use is not measured by an interval meter and who is neither a regulated consumer nor a consumer who has a contract with a retailer who uses retailer-consolidated billing, the licensed distributor shall, i. determine a weighted average rate applicable to the consumer’s billing period, based on the specified Class B rate for each month in the billing period and the hourly net system load shape determined in accordance with the Retail Settlement Code for each month in the billing period, ii. multiply the weighted average rate determined under subparagraph i by the volume of electricity that was distributed to the Class B consumer during the billing period and subtract, in the case of a Class B consumer that is an electricity storage facility, the volume of electricity, if any, that was conveyed into the distribution system of the licensed distributor by the Class B consumer during the billing period, multiplied by the weighted average rate, and iii. adjust the invoice that the licensed distributor issues to the Class B consumer for the billing period by giving a credit for the amount determined under subparagraph ii if the amount is negative or by adding the amount determined under subparagraph ii as an additional charge if the amount is positive. 3. For each Class B consumer whose electricity use is measured by an interval meter and who has a contract with a retailer who uses retailer-consolidated billing, the licensed distributor shall, i. for each month in the Class B consumer’s billing period, multiply the specified Class B rate for that month by the volume of electricity that was distributed to the Class B consumer by the licensed distributor in that month and subtract, in the case of a Class B consumer that is an electricity storage facility, the volume of electricity, if any, that was conveyed into the distribution system of the licensed distributor by the Class B consumer in that month, multiplied by the specified Class B rate for that month, ii. add the monthly amounts determined under subparagraph i for the billing period, and iii. adjust the accounts between the licensed distributor and the retailer with whom the Class B consumer has a contract by giving a credit for the amount determined under subparagraph ii if the amount is negative or by adding the amount determined under subparagraph ii as an additional charge if the amount is positive. 4. For each Class B consumer whose electricity use is not measured by an interval meter and who has a contract with a retailer who uses retailer-consolidated billing, the licensed distributor shall, i. determine a weighted average rate applicable to the consumer’s billing period, based on the specified Class B rate for each month in the billing period and the hourly net system load shape determined in accordance with the Retail Settlement Code for each month in the billing period, ii. multiply the weighted average rate determined under subparagraph i by the volume of electricity that was distributed to the Class B consumer during the billing period and subtract, in the case of a Class B consumer that is an electricity storage facility, the volume of electricity, if any, that was conveyed into the distribution system of the licensed distributor by the Class B consumer during the billing period, multiplied by the weighted average rate, and iii. adjust the accounts between the licensed distributor and the retailer with whom the Class B consumer has a contract by giving a credit for the amount determined under subparagraph ii if the amount is negative or by adding the amount determined under subparagraph ii as an additional charge if the amount is positive. O. Reg. 398/10, s. 6; O. Reg. 311/13, s. 2 (2); O. Reg. 516/17, s. 5. (4.1) Every licensed distributor shall make adjustments with respect to its Class B consumers who are low-volume consumers in accordance with the following rules: 1. For each Class B low-volume consumer, the licensed distributor shall make adjustments in accordance with the rules set out in subsection (4), except that, wherever those rules require the licensed distributor to use the volume of electricity in determining the amount of the adjustment, the licensed distributor shall use the volume of electricity exclusive of the volume for total losses, as defined in the Retail Settlement Code, that is attributed to the consumer. 2. For each Class B low-volume consumer, the licensed distributor shall make separate adjustments in accordance with subsection (4.2) regarding the volume of total losses, as defined in the Retail Settlement Code, that is attributed to the consumer. O. Reg. 311/13, s. 2 (3).

(4.2) Every licensed distributor shall make separate adjustments described in paragraph 2 of subsection (4.1) with respect to its Class B consumers who are low-volume consumers in accordance with the following rules: 1. For each Class B low-volume consumer whose electricity use is measured by an interval meter and who is neither a regulated consumer nor a consumer who has a contract with a retailer who uses retailer-consolidated billing, the licensed distributor shall, i. for each month in the Class B low-volume consumer’s billing period, multiply the specified Class B rate for that month by the volume of total losses, as defined in the Retail Settlement Code, that is attributed to the consumer for that month, ii. add the monthly amounts determined under subparagraph i for the billing period, and iii. adjust the invoice that the licensed distributor issues to the Class B low-volume consumer for the billing period by giving a credit for the amount determined under subparagraph ii if the amount is negative or by adding the amount determined under subparagraph ii as an additional charge if the amount is positive. 2.
