As part of its Joint System relationship with Minnkota Power Cooperative, the NMPA members have access to a diverse electric generation portfolio that includes coal, wind and hydro resources. In terms of nameplate electric generation capacity, about 55% is derived from coal, 34% from wind, 8% from hydro and 3% from other resources.
The Joint System participates in the Midcontinent Independent System Operator (MISO)

All of the Joint System’s generation and load is modeled, scheduled, dispatched and settled financially in the MISO market.
