(a)Why was TB Flats II dependent on Q0542 and why wasn't TB Flats I also dependent on Q0542?What is the significance of the fact that TB Flats II is dependent on Q0542 (240 MW wind projects)? (b)According to the Interconnection Queue,Q0542 has been suspended.Why would TB Flats be dependent on a project that has been suspended? (c)Is Q0542 the same project that is referred to in Mr.Link's testimony at line 126,in which capacity in Eastern Wyoming was set aside for?Why would this have been necessary if the projects have been suspended? (d)For projects that have been suspended,how long does the Company have to reserve capacity for those projects in studies such as this?Please explain. Response to OCS Data Request 15.11 (a)Both the Q0707 and Q0708 (TB Flats I and TB Flats II)system impact study (SIS) reports dated February 8,2018,list Q0542 as a higher priority request that was considered in the report in Appendix 1.This means those SIS reports assumed Q0542 was in-service. (b)The interconnection agreement suspension provision allows an interconnection customer to request suspension of all work associated with the construction and installation of the facilities required to secure interconnection service for up to three years.Suspensions are therefore not indefinite,and PacifiCorp transmission cannot assume suspension will lead to termination.Rather,interconnection customers are pennitted to come out of suspension and continue with their interconnection,and PacifiCorp transmission must honor those rights,as well as the associated timing, which includes considering the projects in-service for purposes of the interconnection studies of projects with higher queue numbers. (c)Yes.See subpart (b)above. (d)See subpart (b)above.
