MIG TF Charter

Examine and investigate the reliability, and market, impacts as well as the interconnection processes/procedures for Generation Units with more than one interconnection in the ERCOT Market. MIG will issue a whitepaper to WMS/ROS at their December meetings

 Goal 

MIG will issue a whitepaper to ROS/WMS containing a list of: Reliability concerns and mitigation actions, Market pros and cons, Policy/Planning issues related to the interconnection process,

for generation units with multiple interconnections in ERCOT.

For ROS/WMS Approval

Where we areAnswers to most initial questions were sent

out to WMS/ROS.Few questions still under reviewWhite paper is being developedOn Schedule for Final presentation in

December (Draft in November).

General DirectionExisting Protocols pretty well cover MIG’s today.

Some refinement/clarification will be requiredExpect that ERCOT will have the ability to direct a MIG to

a specific point during an “ERCOT emergency”Expect a MIG will be able to request a specific point of

interconnection with Notice {still being worked on but current book ends between 3 – 90 Days - (30-90 more likely)}. (Book ends will be a decision point for WMS/ROS (Dec 09)).

PCRR eligible units will be locked to Sept 99 date not only for Commercial Date, but also Generation Interconnect Node.

New Interconnects will follow SGIA guidelines, just like any other new unit (no priority).

A MIG will likely face the risk of CCN Approval for inclusion in TCOS, before the TSP will build the second point of interconnection.
