CARMEL, Ind. — MISO is proposing a biennial review to reduce its “parking lot” list of improvement suggestions, although some stakeholders are putting up resistance.

“We’d like to make sure that good ideas don’t go to the parking lot to linger indeterminately,” Laura Rauch, senior director of transmission planning, said during a Market Subcommittee meeting Thursday

MISO’s parking lot contains improvement ideas submitted to MISO through its issues-submission process. It has become a graveyard of shelved ideas, with some stakeholders complaining that their recommendations remain unaddressed. (See MISO Pledges Review of On-hold Stakeholder Ideas.)

The grid operator said it will clean up the parking lot and eliminate nearly 20 suggestions. In some cases, staff doesn’t have a record of the stakeholder that originally submitted the idea or its full description.

The grid operator said it will use “active,” “inactive,” and “closed” to label the idea list. “Closed” means MISO has no current plans to address the idea and i will fall off the list. Staff will work with stakeholders with inactive projects and determine their feasibility every two years.

Rauch pointed to a suggestion creating a universal resource participation model that has spent years in the parking lot. MISO doesn’t distinguish market participation models by intermittency, energy storage and demand response, leading Rauch to term the suggestion “aspirational” and suggest it should be closed. Stakeholders could always revive the idea by submitting it again to the RTO.

Rauch also said there’s some redundancy among the improvement recommendations.

“To me, this seems like another way MISO isn’t allowing stakeholders to decide when an item doesn’t need attention,” Clean Grid Alliance’s Natalie McIntire said.

Independent Market Monitor David Patton took umbrage with MISO’s move to close his suggestion that a virtual spread product be created in the day-ahead market. It would allow participants to specify the maximum congestion between two points they are willing to pay in a virtual transaction.

Rauch said in this case, staff last delivered a presentation on a virtual spread product in 2012. She said MISO has no plans to address the issue.

Xcel Energy’s Kari Hassler said she was concerned that the grid operator would put recommendations on the chopping block before it has completed its new market platform, which has been billed as being able to host more complex market products.

“We have a lot of projects that are pushed back and waiting in the wings until” MISO’s new market platform is finished, Hassler said.

MISO plans to roll out its day-ahead market on the new, modular market platform next year.
