2016/631 - Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators
Commission Regulation (EU) 2016/631 establishes a network code detailing requirements for the grid connection of power-generating facilities within the European Union. It aims to promote the completion of a fully interconnected internal energy market, enhancing security of energy supply, competitiveness, and consumer benefits. The regulation sets harmonized technical standards for different types of power-generating modules-ranging from basic to advanced capabilities-to ensure operational security, facilitate integration of renewable energy sources, and enable efficient network use. It recognizes regional variances in synchronous electricity systems and allows for national discretion, including derogations where justified. The regulation also mandates effective cooperation between power-generating facility owners and system operators, focusing on dynamic response capabilities during system disturbances and contingency events. Compliance mechanisms and information exchange protocols are established to support stable and secure system operation throughout interconnected transmission and distribution networks. Overall, the code fosters non-discrimination and transparency, contributing to a level playing field and cross-border electricity trade in the EU.
Purpose
Commission Regulation (EU) 2016/631 establishes a network code setting out harmonised technical requirements for the grid connection of power-generating modules across the European Union. The regulation aims to:
- Ensure system security and stability in the interconnected electricity grid.
- Facilitate integration of renewable energy sources (RES).
- Promote fair competition and efficient operation within the internal electricity market.
- Enable transparent and non-discriminatory use of power-generating facilities’ capabilities by system operators.
- Support Union-wide electricity trade by establishing a clear framework for grid connection.
By defining technical and operational standards, the regulation contributes to the swift completion and reliable functioning of an interconnected and integrated European energy market.
Key obligations
Technical requirements for grid connection: The regulation categorises power-generating modules into types A, B, C, and D with increasing levels of technical and operational requirements reflecting their capacity and impact on the system. Requirements cover capabilities such as fault-ride-through, frequency and voltage tolerance, dynamic response, and control interfaces.
System operators’ responsibilities: Transmission system operators (TSOs) and distribution system operators (DSOs) must make use of the capabilities of power-generating modules in a transparent, non-discriminatory manner, with appropriate coordination across regions and synchronous areas.
Power-generating facility owners’ duties: Owners must provide technical documentation (Power-Generating Module Documents - PGMDs) demonstrating compliance with the relevant criteria before connection approval.
Compliance and testing: Operators should implement proportionate compliance testing regimes to ensure ongoing security and stability of system operation.
Regional and synchronous area considerations: Requirements should reflect regional specificities within synchronous areas to account for differences in network characteristics, generation mix, and protection schemes.
Derogations procedure: The regulation allows for exceptions under strict conditions to address local network stability issues or disproportionate cost impacts, subject to approval by regulatory authorities.
Information exchange: Continuous, real-time data exchange between system operators and power-generating facilities is mandated to maintain system state awareness and facilitate operational instructions.
Ancillary services: Larger and more advanced types of power-generating modules are expected to provide ancillary services such as reactive power support, inertia, and frequency control, essential for system security and reliable supply.
Affected products and actors
Power-generating facilities: This includes synchronous power-generating modules, power park modules (such as wind or solar parks), and offshore power park modules connected to the interconnected transmission and distribution networks.
Power-generating facility owners: Natural or legal persons owning facilities that convert primary energy to electricity.
System operators: Transmission system operators (TSOs), distribution system operators (DSOs), including closed distribution system operators (CDSOs), responsible for network management and ensuring compliance with the connection requirements.
Regulatory authorities: National or regional bodies tasked with approving methodologies, tariffs, and connection terms, and authorising any permissible derogations.
Equipment and technologies: Generators at various voltage levels impacting the network, including conventional synchronous machines and renewable-based non-synchronous units.
Implementation timeline
The regulation primarily applies to new power-generating facilities connecting to the grid after the regulation’s entry into force in 2016.
Existing power-generating modules already connected or at advanced planning stages are generally exempt unless significant modernization occurs or a regulatory decision deems new requirements necessary based on system needs and cost-benefit analyses.
National regulatory authorities and system operators are responsible for applying the rules and establishing compliance and testing processes within their jurisdictional timelines following the regulation’s adoption.
The regulation supplements Regulation (EC) No 714/2009 and forms an integral part of the EU’s regulatory framework for electricity markets, with continuous coordination expected to ensure harmonisation and updates aligned with evolving system requirements.
This directive applies to power-generating facilities connected to the interconnected electricity system within the European Union. It covers synchronous power-generating modules, power park modules, and offshore power park modules. The directive establishes minimum technical design and operational requirements for grid connection to ensure system security, facilitate integration of renewable energy sources, support fair competition in the internal electricity market, and enable Union-wide electricity trade. The scope includes new generating facilities, taking into account regional specificities and differences between transmission and distribution systems. Existing generating modules are generally excluded unless substantially modernized or subject to regulatory decisions. Different generator types and voltage levels are covered with tailored requirements for dynamic response, system operator control, and ancillary services to maintain stable and efficient operation of the interconnected electricity system.

The purpose of this document is to provide technical guidance for tests on generating units and interface protection to evaluate their electrical characteristics.
NOTE 1 Mechanical issues are taken into account as far as they influence the electrical characteristics.
The evaluation results are intended to be used to demonstrate conformity of generating units to technical requirements for grid connection. In this context the evaluation results can also be used as part of a certification programme.
NOTE 2 Besides the type test results of the generating unit all additional elements for connection to the grid (e.g. transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant.
The requirements to be evaluated are covered in the following standardization documents:
– EN 50549 1:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 1: connection to a LV distribution network - Generating plants up to and including Type B
– EN 50549 2:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 2: Connection to a MV distribution network - Generating plants up to and including Type B
If grid connection requirements are dealt with in other documents or for other generating module types, where no specific testing procedure is provided, testing methods of this document can be used if applicable.
This document provides evaluation criteria for the conformity assessment of generating units with respect to the abovementioned standardization documents, based on type testing. However, some requirements are applicable on the generating plant level. The assessment of the conformity to these plant requirements are out of the scope of this document. Nevertheless, this document may be used to show the capabilities of a generating unit to be used in a plant.
As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects of the above-mentioned standardization documents, typically when a requirement is evaluated on a plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered.
This document recognizes the existence of specific technical test requirements within several member states that must be complied with.

Frequently Asked Questions
An EU Regulation is a binding legislative act that must be applied in its entirety across the European Union. Unlike directives, regulations do not need to be transposed into national law and are directly applicable in all member states. Regulations are used when uniform application across all EU countries is essential.
Regulation 2016/631 covers "Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators". There are 20 standards associated with this regulation.
Harmonized standards under 2016/631 are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of 2016/631, facilitating CE marking and free movement within the European Economic Area.
