As of September 9, 2026, Google, Xcel Energy, and other utilities and clean-energy groups supported the Midcontinent Independent System Operator (MISO)’s proposed “Zero Injection Generator Interconnection Agreement,” which would create a 90-day review process for generation projects that serve large loads at the same substation and voltage level, including colocated data centers, when the generation has little or no transmission-system impact. [1] The proposal would limit eligible generation to the amount of load it serves and generally prohibit network upgrades beyond the substation, while MISO develops additional processes for large-load additions. Google supported the proposal but asked MISO to expand it to configurations where generation and load are connected through two substations. Environmental groups opposed the proposal, arguing that insufficient safeguards could shift costs to existing customers and create reliability concerns.
