MISO South regulators publicly opposed a postage stamp cost allocation design, potentially setting the stage for a showdown as MISO prepares for a third long-range transmission portfolio.
FERC has allowed MISO to use a separate-but-equal postage stamp rate divided between MISO Midwest and MISO South for some of its major transmission buildout.
MISO revealed that it will use the cost allocation devised for 2011's Multi-Value Project portfolio for its long-term transmission plan.
State commission staff from MISO South questioned MISO's long-range transmission plan at an Entergy State Regional Committee meeting.
The postage-stamp cost allocation method for long-term transmission projects might be coming back in vogue in MISO.
A settlement between PJM and transmission owners over the procedure for cost allocation of major projects is receiving criticism from stakeholders.
FERC ordered settlement procedures to determine cost allocation for PJM transmission projects of 500 kV or more that were approved before February 2013.
PJM says its FERC Order 1000-compliant hybrid cost allocation for regional transmission projects won't be in jeopardy following a federal appellate court ruling last week.
