Turbines & Legislation
The implementation processes of EU policies relevant for turbine manufactures are complex, divers, technical and specific. EUTurbines is monitoring the implementation of EU regulations and decisions and is equally following up on the implantation of Directives that are incorporated into national law by EU countries. EUTurbines pays specific attention to the technical realization and national implementation, concerning the following topics:
Grid Code is a technical specification, which defines the parameters a facility connected to a public electric network has to meet to ensure the safe and secure functioning of the electric system. The most relevant codes for EUTurbines are the Requirements for Generators (RfG) Code, and, to a lesser extent, the Emergency and Restoration and the High Voltage Direct Current (HVDC) Codes. Since the adoption of the codes, EUTurbines activities are mainly focused on their (national) implementation as well as standardization, including (1) Activities within the European Stakeholders Committees (ESCs) of the European Agency for the Cooperation of Energy Regulators (ACER), (2) Development of Implementation Guidance Documents (IGDs) in the ENTSO-E Framework and (3) Revision of standards to adapt them to the latest requirements in the framework of CENELEC.
Gas Quality: Wobbe Index Parameters - Standard EN 16726 – Hydrogen
The European discussion of “Gas Quality” has different dimensions. CEN has been mandated by the Commission to define a EU-wide Wobbe Index (or regional ranges) and to come with a proposal, which would be included in a revised EN 16726 (Gas Infrastructure - Quality of Gas - Group H). The CEN Sector Forum Gas WG identified several scenarios, whose impact to the entire value chain should be assessed. Another increasingly important area is the hydrogen content in natural gas pipelines. In a system where “renewable gas” from excess renewable electricity will be increasingly used and incorporated into the gas pipeline, it is a topic that will be very important for gas turbines manufacturers in the future.
EUTurbines stresses the need to ensure that the discussion on gas quality related matters are conducted in a way that keeps turbine products in the market with a reasonable investment of time and money to adapt to standards. Therefore, EUTurbines experts are active within the CEN Sector Forum Gas WG meetings. EUTurbines also participated in the CEN workshop on hydrogen and is getting more involved in this specific topic and related discussions.
Emission Regulation: Industrial Emission Directive (IED) and the Large Combustion Plants Best Available Techniques
Reference Document (LCP BREF)
The LCP BREF, under the IED, deals with emissions from combustion installations with a rated thermal input exceeding 50 MW. All kinds of conventional power plants used for mechanical power and heat generation are covered in this work. The LCP BREF deﬁnes new standards for BATs and ELVs for large combustion plants. After 5 years, the revision process of the existing BREF reached its end when after the discussion in the IED Article 75 Committee, the BAT Conclusions were published in the EU’s Official Journal in 2017. The revised limit values are applicable for new plants since their publication. In the case of existing plants, Member States have 4 years to ensure compliance with the new values at national level.
For EUTurbines, it is important to recognise the changing role of gas-fired power plants – from baseload to back-up generation, guaranteeing the stability of the grid with an increased share of variable renewable energy sources. This new role has an impact on the way power plants are operated, influencing, at the same time, their emissions. Following the adoption of the BAT conclusions, EUTurbines calls for a consistent, harmonized implementation in the EU Member States without additional national requirements.
