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
