MISO said it will salvage two to-do items from its effort a few years ago to better link up interconnection trends with annual transmission planning.

Presenters at a special two-day meeting of the Planning Advisory Committee advised MISO to consider recommending 765 kV and HVDC transmission lines.

FERC on Tuesday accepted a MISO tariff filing, promising to annually update an unforced capacity-to-intermediate seasonal accredited capacity ratio.

SPP and MISO plan to draft a white paper on rate pancaking and unreserved use, two issues that bedevil utilities along the RTOs’ seam.

MISO will evaluate through the end of the year how it can measure and encourage six generating attributes that it says are necessary to its system operations.

MISO said that a sloped demand curve applied to its recent seasonal auction would have boosted summer clearing prices as much as sixfold.

MISO this week said it will likely operate with almost no firm generating capacity to spare to manage typical summertime peaks.

MISO executives said the capacity market still needs fixing, warning that the surplus gained from last week’s auction is fleeting without long-term changes.

MISO still doesn’t have enough justification to institute a minimum capacity obligation, FERC decided last week.

MISO players weighed the RTO’s recent moves to fortify resource adequacy, including seasonal capacity, accreditation approaches a downward-sloping demand curve.
