In October, ERCOT proposed a new Planning Guide Revision Request (PGRR-120), introducing implications for generator interconnections to its transmission grid. The proposed changes prevent generators from interconnecting if doing so would result in the generator being radial to a series capacitor under N-1 contingency conditions.
What Does This Mean for Developers?
If approved, PGRR-120 will require developers to carefully evaluate their interconnection points, paying particular attention to the placement of series capacitors in the grid.
ERCOT has proposed that these changes aren’t effective until after April 1, 2025, giving developers with in-process interconnection requests or modifications time to proceed under the existing rules and offering a temporary window for projects already underway.
