– Reminders below to involve business in building bids and offers

ERCOT• So QSE BUSINESS INVOLVEMENT IS CRITICAL for reasonable pricing and business

activities

– All QSEs (with and without Load and Resources)- • May submit a limited amount of DAM Energy Only Offers and DAM Energy Bids

that do not represent actual Resources or Loads (virtual bids and offers)

• QSEs can only bid/offer up to 50MW total (later becomes 500MW)

• It is important that the submitted bids be reasonably priced for producing appropriate prices and results.
