Stakeholders have several lingering questions as MISO continues to draw up a “zero-injection” avenue for large loads with planned on-site generation.

Stakeholders told MISO it might have anticipated an impending cost increase for a long-range transmission project in the works in Minnesota that jumped about 43% in price to nearly $1.4 billion.

Multiple transmission owners have questioned the need behind a suggestion that MISO work more checks into its process for reviewing troubled transmission projects.

The $1.6 billion Joint Targeted Interconnection Queue transmission portfolio of SPP and MISO remains in play even though the Department of Energy has reneged on almost a half billion dollars in funding.

MISO is taking load updates and stakeholder suggestions as part of a pilot program to improve its long-term load forecasting.

The cost estimate for MISO’s 2025 Transmission Expansion Plan has fallen slightly from previous estimates to $12.36 billion.

MISO confirmed it will make a second bid to FERC to establish a temporary fast lane in its interconnection queue, this time limiting the process to 50 generation projects.

Groups of generation owners and developers have asked MISO to adopt a queue fast lane only as a last resort and employ a more limited process that involves scoring criteria to gain entry.

Stakeholders want MISO to develop a smaller, congestion-relieving transmission study after this year’s near-term congestion study focused on how best to sequence transmission outages needed for construction of long-range transmission projects.

MISO will take a breather from its long-range transmission planning over 2025 to retool the 20-year future scenarios that are the foundation of the transmission portfolios.
