​Market price maps

The ISO wholesale power market prices electricity based on the cost of generating and delivering it from particular grid locations called nodes. One energy market runs the day before the energy is needed (day ahead market), while another one runs in real-time to balance last minute demand needs.


Switch between the Day-ahead, Real-time pre-dispatch and Real-time dispatch locational marginal price (LMP) maps using the drop down menu at the top of the map.  Prices are shown in megawatt-hours ($/MWh).

How to use the maps

Change between maps using the drop down menu on the top left corner of the map
