Another recently adopted change to ISO-NE energy market pricing rules will (pending FERC final approval) affect wind power projects. Today, intermittent generators like wind projects participating in ISO's energy markets can simply bid zero ($0 per MWh) and be assured of being selected and getting paid the real-time market clearing price, a practice referred to as being a "price taker." There are times, however, when the output of all projects acting as price takers would exceed the load. In such instances, ISO-NE operators do not have a clear protocol to follow and often have made dispatch decisions that are not economically optimal. Today there is a $0 price floor on the market-clearing price for energy. ISO-NE energy markets currently do not allow generators to make negative price offers. The proposal under consideration would allow the energy price to go negative, as low as -$150/MWh. This change would benefit wind generators by allowing them to enter negatively priced bids to ensure they are dispatched.
