Compensation for distributors, unit sub-meter providers and the IESO
 3. (1) The Board shall, as often as is necessary and no less frequently than annually, calculate the amount of the charge to be collected by the IESO under subsection (2) for each kilowatt hour of electricity that is withdrawn from the IESO-controlled grid, as determined in accordance with the market rules, for use by consumers in Ontario, or that is supplied by embedded generators for use by consumers in Ontario, so that the total amount forecast to be collected is equal to the sum of the total amount of rate assistance to be provided and OESP administrative costs. (2) The IESO shall collect the charge calculated by the Board under subsection (1) from market participants and any other person who, with the approval of the IESO, withdraws electricity from the IESO-controlled grid for use by consumers in Ontario. (3) For the purposes of subsection (2), the amount that the IESO shall collect from each market participant and any other person contemplated in that subsection shall be based on the total of, (a) the net volume of electricity withdrawn by the market participant or other person from the IESO-controlled grid during the month; and (b) if the market participant is a licensed distributor, the sum of, (i) the total volume of electricity supplied by embedded generators during the month to the market participant, adjusted for losses as required by the Retail Settlement Code, and (ii) the total volume of electricity supplied by embedded generators during the month to all embedded distributors for whom the market participant is the host distributor, adjusted for losses as required by the Retail Settlement Code. (4) Each month, the IESO shall pay distributors, unit sub-meter providers and any other persons or entities that are entitled to compensation under subsection 79.2 (9) of the Act the compensation to which they are entitled under that subsection, and shall retain for itself the compensation to which it is entitled under that subsection. (5) In any year or other period for which the Board calculates the charge under subsection (1), if the amount collected under subsection (2) is greater or less than the sum of the total amount of rate assistance provided and the OESP administrative costs, the excess or shortfall shall be considered by the Board in calculating the amount of the charge that is to be collected under subsection (2) for a subsequent period or periods. (6) For the purpose of calculating the amount referred to in subsection (1), (a) at least 60 days before the end of each calendar year the IESO shall submit to the Board, (i) a forecast of the number of net kilowatt hours of electricity that are expected to be withdrawn from the IESO-controlled grid, as determined in accordance with the market rules, for use by consumers within Ontario during the IESO’s next fiscal year, (ii) a forecast of the total volume of electricity that is expected to be supplied to distributors and embedded distributors by embedded generators, and (iii) documentation supporting the forecasts referred to in subclauses (i) and (ii), and (b) before the expiry of a period specified by the Board, the IESO shall submit to the Board any other information the Board may require for the purposes of this Regulation, in the form specified by the Board.
