Capacity optimization designed model
for SESAM
Capacity optimization designed model
for SESAM
Instead of one bidding area, four bidding areas are
implemented
Imports and exports from Latvia and imports from Russia
Capacity auctioned in implicit way for importers and
exporters
Curtailment leads to pro-rata cut in bid volumes
automatically
In pro-rata curtailment, the larger the bidded quantity is,
the more volume the bids get as compared to bids with
smaller quantities
Capacity optimization designed model
for SESAM
As EIC issuing authority, EIC codes must be appointed
for these areas by Elering
Elering must send capacities to SESAM for the
ESTLINK import/export areas using these EIC codes
Flows resulting from the price calculation will be
reported by ETSO ESS scheduling XML messages. Flows
are reported between ESTLINK and the 3 import/export
Areas
Importers and exporters of electricity must also be
appointed EIC codes by Elering
EIC codes are per party/area and not per trading
account
Capacity Optimization method
Cross-border
capacity limits
for PX Trade
(XB max)
NPS SESAM
Cross-border bids
(NPS)
All cross-border import and export bids
are accepted for spot-price calculation
Bids to PX Trade
Imp < XB max (import)
Exp < XB max (export)
Bid- cutting until
Imp = XB max (import) and
Exp = XB max (export)
Accepted cross-border bids
for spot-price calculation
NO
YES
