This legislation mandates that Transmission Organizations permit aggregators of retail customers to submit bids into organized wholesale electric markets. These bids would aggregate the demand flexibility of customers served by utilities that distributed more than 4 million megawatt-hours in the previous fiscal year. The bill specifies that this requirement applies notwithstanding any State law or commission prohibition on who may bid into these markets. By enabling such participation, the measure aims to integrate demand-side resources more effectively into the grid. The Federal Energy Regulatory Commission (FERC) is directed to promulgate a final rule to implement these provisions within 12 months of the bill's enactment.
