Capacity optimization between Estonia - Latvia Ingrid Arus Electricity Market Development Manager Elering OĂœ

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
