A round-up of news from the SPP Markets and Operations Policy Committee on July 14 and 15.

SPP's Z2 credit project, years in development and the source of much member frustration, is on track to be completed in 2016.

SPP members approved four over-budget transmission projects and sent three others back to the drawing board amid widespread criticism of the process used to estimate project costs.

SPP will change the way it calculates offer caps for generators under market mitigation in a “design approach” approved last week by the MOPC.
