This Nodal Protocol Revision Request (NPRR) eliminates the requirement that Qualified Scheduling Entities (QSEs) representing Wind-powered Generation Resources (WGRs) must provide a 7-day forecast in their COP. Instead, for hours 49-168, QSEs representing WGRs shall, using their best estimate enter a High Sustained Limit which may be based on the wind power profile as published on the ERCOT website.
The market has already determined that a single forecast provided by ERCOT is more reliable than individual forecasts developed and submitted by each WGR. This is evidenced by ERCOT’s provision of the Short Term Wind-Power Forecast (STWPF) and the requirement that QSE’s representing WGRs must use this forecast in their COP for hours 1-48. It is not in the best interest of the market to require each WGR to develop a 7-day forecast. Such forecasts would be inherently unreliable and would also vary widely across WGRs.
