NO, If an SC self provides 130 MW of SPIN capacity yet the calculated market requirement is only 100MW, the self-provided amount of 120 MW will be accepted for SPIN and none of the EXCESS 30 MW of capacity considered for other A/S services. Please Note if in this example the SC's SPIN obligation is calculated to be 90 MW, the over self provided portion (100MW - 90MW) = 10 MW would receive a payment. In this example there is an additional 20 MW of EXCESS above the total market requirement that "gets left on the table" which will receive no compensation. * If self provision reserves are offered in excess of the total quantity required for the total market, will the ISO take them all anyway or will the offerings be truncated and perhaps roll into a subsequent service (if offered as self provide in that service). NO, As in the above answer. The total Self provided quantity will be accepted and there would be no reduction of the preferred schedule even if this amount is ABOVE the total market requirement.
