SPP continues to accrue multimillion-dollar settlements from its market-to-market (M2M) process with MISO following the one-time anomaly during the February winter storm.
“We’ve moved on from February,” SPP’s Jack Williamson told the Seams Advisory Group during its conference call Thursday.
Williamson said SPP recorded $13.25 million in M2M settlements from its seams neighbor in April, pushing its total to $146.63 million since the two RTOs began the process in March 2014. The settlements have been in SPP’s favor eight of the last nine months, interrupted only by MISO’s record $51.49 million haul in February.
SPP has totaled $30.34 million in settlements over the two months since.
Temporary and permanent flowgates were binding for 2,331 hours during April, 750 more hours than the previous month. Three flowgates, two north and east of Kansas City, accounted for $8.66 million of SPP’s positive settlements.
The grid operators exchange M2M settlements for redispatch based on the non-monitoring RTO’s market flow in relation to firm flow entitlements. The settlements have been in SPP’s favor 17 of the last 19 months and 56 times in the process’s 74 months.
Joint Queue Study Discusses Cost Allocation
Senior Interregional Coordinator Clint Savoy told the group that the SPP and MISO staffers involved in the RTOs’ joint targeted interconnection queue study have completed an initial draft of potential transmission solutions and a cost/benefit analysis.
Next up: cost-allocation discussions.
Savoy declined to say whether the team has identified any projects so far. He encouraged stakeholders to participate in the team’s next scheduled meeting on July 7.
SPP and MISO leadership have tasked staff with identifying “comprehensive, cost-effective and efficient” upgrade projects, with a focus on projects near their seam that support both organizations’ interconnection processes. (See MISO, SPP to Conduct Targeted Transmission Study.)
Savoy also said SPP has reached an emergency energy transactions agreement with Xcel Energy’s Public Service Company of Colorado. He said the agreement is similar to those SPP already has with MISO and Canada’s SaskPower.
Under the agreement, a party must be in a Level 2 or higher energy emergency alert and must formally request the transfer. The final settlement will include an energy portion and a transmission charge.
