MISO this week promised five months of additional stakeholder discussion on its Order 2222 compliance plan before it attempts a second filing with FERC to take care of the commission’s concerns.
In October, FERC ordered MISO to propose an earlier start date than its proposed 2030 date and explore the possibility of allowing DER aggregations across multiple pricing nodes. (See FERC: MISO’s 2030 Finish Date on Order 2222 Compliance not Soon Enough.)
FERC allowed MISO an extension until May 10 to hold additional discussions with stakeholders before proposing a new Order 2222 effective date and deciding whether it can handle multinodal aggregations. The conversations largely will take place in MISO DER Task Force meetings.
During a Dec. 11 DER Task Force meeting, Managing Assistant General Counsel Michael Kessler said MISO is in the process of evaluating whether multinodal aggregations might be possible within the footprint.
Kessler also said while FERC appeared to agree MISO needs its new market platform in place before it can handle offers from DER aggregations, it must land on a closer go-live date. The RTO plans to reveal a new date and its reasoning behind it to stakeholders at the April meeting of the task force.
“We’re going to have a busy run for the next few months,” said DER Task Force Chair Zac Callen, who also is an economic analyst with the Illinois Commerce Commission.
MISO’s DER Program Manager Paul Kasper said creating bidding parameters under a multinodal aggregation will be “technically intensive.” He also said MISO will need coordination with distribution utilities to answer FERC’s questions about MISO’s proposed reliability reviews for aggregations and coordination protocols between MISO, distribution utilities and aggregators.
MISO originally said it would handle a new go-live date and multinodal aggregations in a filing separate from FERC’s other, less-intensive clarifying questions on MISO’s compliance plan. However, the grid operator since decided to make a single filing to satisfy the commission’s asks.
