About Midcontinent Independent System Operator Inc.
Midcontinent Independent System Operator Inc. (doing business as Miso), a tax-exempt non-profit organization headquartered in Carmel, Indiana, operates as a federal grant recipient focused on electric grid operations, resilience, and uncertainty management, with recent work centered on cooperative agreements with the Department of Energy's Office of Energy Efficiency and Renewable Energy rather than federal contracting. Miso holds no federal contracts as a prime contractor, and its federal footprint consists almost entirely of grant work (97% of recent awards) rather than competitive procurement.
Miso's grant portfolio centers on grid modernization and renewable energy integration. The vendor is the prime recipient of a cooperative agreement from EERE (awarded October 2024, completion March 2026) to build an operations uncertainty platform addressing variability and uncertainty management in large electric grids. In its sub-recipient role, Miso supports grid resilience and innovation through a subaward from the Department of Commerce Minnesota on the JTIQ project and provides system-operator input on grid services and performance metrics to GE Vernova Operations LLC on a renewable energy integration subaward. A third sub-award from Georgia Tech Research Corp (awarded September 2021) positioned Miso as a subject-matter partner on the Risk-Aware Market Clearing project, which applies machine learning and stochastic optimization to MISO's day-ahead forward reliability assessment, look-ahead commitment, and real-time security-constrained economic dispatch challenges.
The source data shows significant historical award volume (101 total awards spanning 2003 to present) but the majority reflects real-property lease and rental agreements with GSA Public Buildings Service (93 awards under NAICS 531311, Lessors of Nonresidential Buildings), which dominate the award count but carry minimal combined potential value ($310 thousand). Recent federal engagement (2024–2025) has shifted to energy-sector grant work with EERE and Commerce, representing Miso's substantive federal market position. Combined potential value across all awards is $746 thousand, though obligated dollars total $20.1 million, signaling that older lease agreements carried far larger realized commitments than current potential values indicate.
