Baltic Sea Offshore Grid Presentation by Taavi Veskimägi, CEO of Elering AS In Fingrid Current 10.3.2020.

1. Baltic Sea Offshore Grid

2. • Electricity and gas transmission
system operator with the primary
task of ensuring a high-quality
energy supply to Estonian
consumers.
• Electricity and gas network consists
internal transmission network and
cross boarder interconnectors
• Elering ensures conditions for well-
functioning, efficient and
transparent electricity market

4. Baltic Sea Offshore
Grid Initiative
WHY?
• Regional energy sector have to be fully decarbonised
and the Baltic Sea wind plays a key role;
• Many studies (Flex4RES, BEMIP Study of Baltic Offshore
Wind ) have shown if we are acting together it makes
energy transition faster and cheaper for all nations.
• converter-based production (onshore and offshore)
brings instability, we need a stronger and more
connected power system
WHAT?
• The dual purpose, simultaneously as interconnectors
between markets and interconnection points for wind
farms.

5. Baltic Sea Wind potential
STUDY ON BALTIC OFFSHORE WIND ENERGY COOPERATION UNDER BEMIP
Summary of identified potential offshore wind
capacity in the BEMIP member countries
Ambitious scenario
reflecting an achievable
pathway
12.7 GW in 2030
32.1 GW in 2050
6.5 GW in 2030
17 GW in 2050.
2020 expected level of 2.5 GW
Offshore wind power in the Baltic Sea Area
Low deployment scenario

6. • Converter-based production
(onshore and offshore) speed is
clearly progressive
21TWh 2016 70 TWh 2022
• The location of these
investments creates an energy
surplus that cannot entirely be
conveyed to consumption
centres
• Baltic Sea Offshore Grid is part
of the solution
• The energy system of the future
must cope with greater flexibility
so we need a stronger and more
connected power system
• „Zero-cost“ energy enables
sector coupling e.g power to X
(gas, heat)

7. Grid cost is lower in the cooperation scenarios than in the
National Policy scenario.
STUDY ON BALTIC OFFSHORE WIND ENERGY COOPERATION UNDER BEMIP
• additional interconnector capacity provided alternative export routes for the power
surplus thus reducing the overall costs related to congestion.
• with coordination, offshore capacity is installed closer to areas where additional
capacity is needed
Annualised social welfare costs of redispatch and grid upgrades across the BEMIP region

8. Baltic Sea Offshore Grid
Initiative
To start a dialogue „How to prepare grid connections for offshore
wind generation“
• Political Declaration on Offshore Energy cooperation
between Baltic Sea Countries (at least Baltic-Nordic countries)
• Highlight Baltic Sea Offshore Grid Initiative in revised BEMIP
• Baltic Sea Offshore Grid Initiative to conduct pre-feasibility
studies for a joint offshore power network
• Governments should commit TSO-s to take a driver seat,
TSO-s have the skills, existing cooperation network and the
capabilities; Next TYNDP 2022 (not single project based but
integral part of Baltic Sea region power system)
• Highlight the BEMIP region in the EU Offshore Wind Strategy
• With the help of EU (e.g Just Transition Mechanism, CEF etc)

9. Thank you!
