Midcontinent Independent System Operator (MISO)
OMS and MISO
A relatively low turnout of constructed capacity in recent years could deepen a potential 1-GW capacity deficit in summer 2025 to more than 14 GW by summer 2029, MISO and OMS revealed in a five-year projection.
MISO and SPP
Two years after announcing its $1.8 billion Joint Targeted Interconnection Queue transmission portfolio with SPP, MISO is putting final touches on FERC filings to make it happen.
Fagen, Inc.
The proceedings will look into the practice by MISO, PJM, SPP and ISO-NE of allowing transmission owners to self-fund network upgrades needed to bring generation online, saying the practice may amount to favoring TOs over interconnection customers.
SPP
SPP’s Board of Directors has added its approval to a proposed tariff revision that establishes a cost-allocation framework for projects in the JTIQ with MISO.
Xcel Energy
FERC authorized an exception to MISO’s interconnection rights transfer process, allowing two Xcel Energy subsidiaries to cooperate on a replacement of a coal-fired plant with a solar farm.
Entergy
MISO’s 2024 Transmission Expansion Plan increased slightly in cost to $5.8 billion while the Southern Renewable Energy Association requested MISO explore an alternative to an Entergy Texas reliability project.
Dynegy
Nearly a decade after the MISO capacity auction in which Dynegy was found to have manipulated clearing prices, FERC has directed hearing and settlement procedures in the case.
National Grid Renewables
MISO said new queue entries must wait while it takes another swing at imposing an annual megawatt cap on its interconnection queue.
Entergy
FERC ruled that MISO can apply new settlement practices to generators physically disconnected from the grid during extensive transmission outages triggered by extreme events.

MISO said a riskier operating environment means it needs a more nuanced approach to its regulation reserve requirements.
