Given the load and resource diversity between MISO South and the rest of MISO and the lack of transmission ties currently, that transmission expansion should provide large net benefits. [...] MISO’s LRTP analysis accounts for some of this benefit by quantifying the value of regional transmission for reducing the risk of loss of load from localized correlated generation failures during periods of extreme weather,47 though the value is likely far greater for interregional transmission because of the larger weather and climate diversity between MISO and PJM. [...] Analyses by the Brattle Group and others have confirmed the benefits of proactive multi-value transmission planning, rather than the current reactive approach to upgrading transmission through the generator interconnection process, including in MISO and PJM.57 It is also essential for transmission planning to account for the multiple types of transmission benefits, as only accounting for a few cat. [...] Another potential starting point for synchronized generation and transmission planning is to identify high-quality renewable energy resource zones and then plan transmission to access them, building on the success of the MISO MVP and ERCOT CREZ studies, and more recently the renewable energy zones being developed as part of the Illinois Renewable Energy Access Plan (REAP) process. [...] MISO and PJM and their states and stakeholders should begin discussions to develop a workable cost allocation mechanism to pay for interregional transmission, likely informed by the distribution of benefits identified in the planning studies proposed later in this paper, and which should reflect the full range of transmission benefits discussed previously.
