DER growth poses a host of new and significant challenges for the electricity system in the MISO region. These challenges span the realms of reliable operations, efficient markets and forward-looking resource planning. DERs also pose jurisdictional issues at the interface of the MISO-managed, high-voltage transmission system and state-regulated, lower-voltage distribution systems.
The current processes for existing DER such as demand response and load modifying resources may also need to evolve in the future.
Consistent with its vision to be the most reliable, value-creating RTO, MISO must continue to enable reliable operations by coordinating across the transmission and distribution interface.
