Storage-as-transmission-only assets (SATOA)
ISO-NE is developing a process for allowing energy storage projects to be used as transmission assets.
The Market Subcommittee discussed how a storage asset solving transmission needs could also participate in the energy market.
SPP stakeholders endorsed the RTO’s latest transmission planning assessment but also withheld approval of a 345-kV, double-circuit project in West Texas.
The MISO Market Subcommittee meeting ran the gamut of storage participation, discovery of a longstanding energy pricing error and FTR underfunding.
MISO’s first rule set for storage resources functioning as transmission assets passed muster with FERC, though James Danly opposed the plan.
MISO defended its first storage-as-transmission proposal, maintaining the plan is a good interim measure while the RTO designs a permanent approach.
MISO is mounting a third attempt to gain FERC approval to overhaul the cost allocation design for economic transmission projects after previous rejections.
Two market efficiency projects approved by MISO face continued obstacles, while two others slated for inclusion in MTEP 19 must wait longer for approval.
About 200 people attended the Energy Storage Association's annual Policy Forum at the National Press Club in D.C.
MISO’s first storage-as-transmission proposal has drawn protests saying the plan gives transmission owners an unfair advantage in developing the resources.
