50Hertz – one of the greenest grids worldwide Wind generation penetration level (ratio of installed wind capacity to total generation capacity)
Source: Alstom Grid/U.S. Department of Energy 2011
50Hertz is among the global leaders in system integration of RES. 7
TSOs are the backbone of a secure energy supply Responsibilities for society Our four core activities:
1. Transmission grid operator (On- and Offshore) 2. System operator 3. Market facilitator 4. ‘Trustee’ for renewable energies (RE) and combined heat-processes
Systemsecurity
Integration of Renewables
EU Market Development
The TSOs and especially 50Hertz play a key role for German society. 8

The current RE capacity of ~21 GW is expected to more than double within 10 years. 10
The 50Hertz-area is characterized by strong RE generation and low load Electricity generation [TWh] Generation surplus
Centers of demand
-14%
Renewable generation
+27% Demand surplus
Main grid construction projects
50Hertz is particularly affected by the challenges resulting from volatile RES. 11
Our understanding of 100% RES integration
• Stable and secure grid connection and operation (SoS) • Growing transport capacities (Grid extension/ enforcement) • Public acceptance/ awareness of RES and grid enforcement
• Short-term enhancement of storage capacities • R&D efforts for transmission technologies and long term energy transformation • Well-trained personnel
• Stable legal and regulatory framework
50Hertz is fully committed to realizing the ‘energy transformation’. 12

Strategies for successful RE grid integration Effectiveness Short-term
Grid management
• Ancillary services for balancing • International grid control cooperation • European real-time warning system • Improvement of RE forecasting • Data exchange with distribution level • Demand response
Long-term
Framework improvement
• Legal and regulatory conditions • Market development • Skill-building and talent recruitment
Infrastructure development
• Domestic grid extension • Upgrade of existing assets • Offshore grid development • Interconnectors to neighbors • European grid planning
Future topics
• HVDC overlay grid • Storage technologies • New transmission technologies • Smart grids
50Hertz is active in all areas to enable an energy system based on RES. 14
System security interventions according to German energy legislation Possible remedial actions in a sample case of unexpectedly strong wind generation* § 13(1) EnWG
Grid-related actions
§11 EEG / § 13(2) EnWG
RES curtailment
Market-related actions
E.g.
E.g.
E.g.
• loop flows
•
•
Local curtailment
•
Curtailment in entire control area
• voltage level • control power
Redispatch and countertrading
•
Cross-border redispatch
•
Load management of large consumers
•
Curtailment of conventional plants up to technical minimum
RES curtailment only when all other interventions have been insufficient. 15
German grid control cooperation is gradually extended to neighboring countries Objectives • Avoid counter-activation of reserves • Mutual exchange of reserves • Optimized procurement and operation of reserves Energinet.dk

In the medium and long term grid development is crucial for a successful energy transformation approx. 30 GW
approx. 25 GW
approx. 3.6 GW approx. 3.6 GW approx. 4.8 GW
Demand centres
•
Particularly the existing north-south routes are already today at full capacity during strong winds
•
Until 2020: Approx. 50-60 GW new RES production vs. 12 GW new transport capacity
Increase of congestions cannot be avoided with the currently implemented projects.

The German grid development plan foresees a DC overlay-grid Objectives •
Support North-South/ Northeast-Southwest flows
•
Supply Southern Germany
•
Stabilization of the AC grid
•
Extension possibilities in North-South and East-West-directions
Key figures •
Total investments approx. €20 bill.

Timeline: operational from 2022
LEITSZENARIO B 2022
19
Upcoming issues in the context of the German energy transformation • Follow-up model of RES-support scheme with stronger focus on market integration of RES • Higher involvement of RES in system security and system services, increased data exchange in real time • No further disconnection between grid development and RE development • Increasing public acceptance, compensation possibilities for municipalities • Network extension is expensive but costs only ~5% of the annual volume of ‘EEG’ funding (about €14.1 billion in 2012) • Social acceptability of increasing costs Foreign countries observe how Germany deals with these challenges. 20

Atlantic Wind Connection (AWC)
•
10 year plan to build a 350 mile subsea HVDC transmission system off mid-Atlantic states (Multi-terminal HVDC VSC)
•
Project purpose:
to serve as an efficient collector of AC power from offshore wind farms; to relieve transmission congestion on the eastern AC grid; to improve regional system reliability.
•
Up to 7,000 MW wind production, 2,000 MW interconnector for 4 states
