  2. Reload PFV • Concern that need to be addressed: • The RC need to have an option in PFV to allow gradual reload of markets and non markets during TLR level 3 , 4 or 5 events. • Without the option of a gradual reload in PFV, a reload situation without capping the net impact of markets and non markets could cause an unexpected sudden increase of the real time loading of the flow gate above the SOL that was not anticipated by the RC and could not have been anticipated by the RC. • The RC doesn’t know how much economic dispatch potential of markets and non-markets was temporary re-dispatched during a TLR level 3, 4 or 5 event to resolve the congestion and maintain the flow gate loading below limit.

  5. Reload PFV • Solution • PFV software allows the RC to set a max flow Target for a reload situation. (see example previous slide) • In that situation the Markets and Non-Markets will still get a net GTL Target that is higher than their current hour net GTL impact. The Target will be based on their current impacts calculated from real time plus a calculated reload value. • The reload value will be allocated to the GTL of Markets and non-Markets based on their >5% FWD impact. For TLR level 3 based on the Non Firm >5% FWD GTL impacts and for TLR Level 5 based on all >5% FWD GTL impacts. • Full reload without Targets for Markets and Non Markets will only occur if a TLR level 1 or 0 is issued.
