MISO's 'zero injection' fast-track proposal gains major backers
Utility Dive Surfaced Read the original
The Midcontinent Independent System Operator has proposed a ‘zero injection’ fast-track process that would expedite interconnection reviews for generating projects serving large loads through the same substation, including co-located loads such as data centers paired with on-site generation. The proposal has drawn backing from Google, Xcel Energy and other stakeholders. It remains a proposal pending review, with implications for the Federal Energy Regulatory Commission given MISO’s multi-state footprint. The measured effect so far is industry support rather than an approved rule change.

Why interconnection queues are the bottleneck
Generator interconnection studies in the Midcontinent Independent System Operator (MISO) footprint, which spans 15 US states and Manitoba, routinely take years because every new project is assessed for its impact on the shared transmission system, creating a persistent backlog. Data center operators seeking co-located, behind-the-meter generation to power large loads have pushed grid operators to distinguish projects that inject no power onto the grid from conventional generators, arguing the former pose negligible reliability risk and should not face the same multi-year review. MISO’s proposal would create a Zero-Injection Generator Interconnection Agreement offering a 90-day review for such projects, a structural change stakeholders are still debating before any filing with the Federal Energy Regulatory Commission.
What an operator should do
Transmission planners and interconnection queue managers at MISO-footprint utilities should evaluate how a zero-injection carve-out would affect queue prioritization and study timelines for co-located large-load projects, since faster-tracked reviews change the sequencing of capacity and network upgrade obligations. Utilities negotiating large-load interconnection agreements, particularly for data center customers proposing on-site generation, should engage now in the stakeholder process to shape eligibility criteria and cost-allocation treatment before any filing reaches the Federal Energy Regulatory Commission. Resource planning and regulatory affairs functions should jointly assess whether this shifts risk toward faster but less thoroughly studied interconnections.
Constraints
The proposal must still clear MISO’s stakeholder approval process and any subsequent filing at the Federal Energy Regulatory Commission before it can be implemented, and its reliability implications for shared substations under fast-tracked review have not yet been tested in practice.
