European Framework

The energy policy of the European Union has set as a priority the achievement of an integrated European Energy Market, which will offer a more cost-effective and competitive electricity system, enhanced security and cross-border solidarity by integrating a greater share of Renewable Energy Sources.

The roadmap to this European energy integration requires both the development of the necessary interconnections aiming at the unrestricted electricity flow from low-price areas to higher-price areas, which will contribute to the reduction of energy costs through price convergence, and the harmonisation of rules and policies of the individual energy markets of all EU member states.

The Third Energy EU package, known as Clean Energy Package, approved in 2019, proposes an adaptation of a new European enegy policy framework, to facilitate the transition away from fossils fuels towards cleaner energy. The Electricity Regulation (EC) 714/2009 was revised in order to become more flexible and adjust to the new commercial reality. The Clean Energy Package sets, among others, a new EU target for 2030 by reaching the percentage of 32% for Renewable Enrgy Sources in the EU’s energy mix. The Clean Energy Package consists of the following Regulatory Framework:

The new electricity market design is intended to better fit the future electricity markets, which will be characterised by more variable and decentralised production, an increased interdependence between cross-border systems and opportunities for consumers to participate in the market through demand response, aggregation, self-generation, smart metering and storage.

Europe’s cross-border electricity networks are operated according to rules that help govern the work of operators and determine how access to electricity is given to users across the EU. In the past, these grid operation and trading rules were drawn up nationally. As electricity is increasingly interconnected between countries, the EU-wide rules effectively manage these electricity flows in the internal energy market. These rules, known as network codes or guidelines, are legally binding European Commission implementing Regulations. They govern all cross-border electricity market transactions and system operations alongside the Regulation on conditions for accessing the network for cross-border electricity exchanges, according to the Regulation (EU) 2009/714.

 

 

The Network Codes are distinguished as follows:

The Connection Codes consist of:

  1. Regulation (EU) 2016/631 (‘RfG’) sets out detailed rules related to the connection of, principally, new power generating installations to national electricity networks.
  2. Regulation (EU) 2016/1388  (‘DCC’)sets out detailed rules related to the connection of, principally, new demand facilities to national electricity networks.
  3. Regulation (EU) 2016/1447 (‘HVDC’) sets out detailed rules related to the connection of, principally, new high-voltage direct current systems to national electricity networks.

For more information on the Connection Codes please visit the website of ENTSO-E.

The System Operation Codes consist of:

  1. Regulation (EU) 2017/1485  (‘SoGL’) which establishes a framework for the maintenance of the secure operation of the interconnected transmission system in real time,
  2. Regulation (EU) 2017/2196  (‘ER’) which sets down rules related to the management of the electricity transmission system in emergency, blackout and restoration states. The main objective of the relevant rules is to bring the system back to its normal state.

The Market Codes consist of:

  1. Regulation (ΕU) 2015/1222 (‘CACM’) governs the establishment of cross-border EU electricity markets in the day-ahead and intraday timeframes, as well as methods for the calculation of interconnection capacity.
  2. Regulation (EU) 2016/1719 (‘FCA’) establishes a framework for the calculation and allocation of interconnection capacity, and for cross-border trading, in forward markets (i.e. timeframes longer than day-ahead).
  3. Regulation (EU) 2017/2195 (‘EBGL’) sets down rules on the operation of balancing markets, i.e. those markets that transmission system operators (TSOs) use to procure energy and capacity to keep the system in balance in real time. The objectives of the guideline include increasing the opportunities for cross-border trading and the efficiency of balancing markets.
