Eolian · Direct response
Eolian sought clarification that generation located electrically close to a large load could qualify for permanent limited service if it could constrain grid withdrawals over the long term. FERC dismissed the request because the preliminary order was not final.
Eolian request and FERC discussion (unpaginated)Commissioner David LaCerte · Direct response
LaCerte supported the order as a way to identify gaps in large-load tariffs. He expected a timely response with evidence about the region’s own rules, not a final nationwide tariff imposed in June.
