IEC TS 62600-201:2025 establishes a system for analysing and reporting, through estimation or direct measurement, the theoretical tidal current energy resource in oceanic areas including estuaries (to the limit of tidal influence) that can be suitable for the installation of one or more TECs. It is intended to be applied at various stages of project life cycle to provide suitably accurate estimates of the tidal resource to enable the arrays’ projected annual energy production to be calculated at each TEC location in conjunction with IEC TS 62600-200.
The purpose of this document is to provide a uniform methodology that will ensure consistency and accuracy in the estimation, measurement, characterization and analysis of the theoretical tidal current resource at sites that could be suitable for the installation of individual or arrays of Tidal Energy Converters (TECs), together with defining a standardised methodology with which this resource can be described and reported. Application of the estimation, measurement and analysis techniques recommended in this document will ensure that resource assessment is undertaken in a consistent and accurate manner. This document presents techniques that are expected to provide fair and suitably accurate results that can be replicated by others.
This document describes only the aspects of the resource required to calculate AEP and assess its uncertainty; e.g. it does not describe aspects of the resource required to evaluate design loads or to satisfy environmental regulations. Furthermore, this document is not intended to cover every eventuality that can be relevant for any particular project. Therefore, this document assumes that the user has access to, and reviews, other relevant IEC documentation before undertaking work (e.g. surveys and modelling) which could also satisfy other requirements.

This document is concerned with the assessment of fish survival in pumping stations and hydropower plants, defined as the fraction of fish that passes an installation without significant injury. It does not concern indirect consequences of such installations, usually included in the notions ‘fish safety’ or ‘fish-friendliness’, like avoidance of fish affecting migration, behavioural changes, injury during attempted upstream passage, temporary stunning of fish resulting in potential predation, or depleted oxygen levels.
This document applies to pumps and turbines in pumping stations and hydropower plants that operate in or between bodies of surface water, in rivers, in streams or estuaries containing resident and/or migratory fish stocks. Installations include centrifugal pumps (radial type, mixed-flow type, axial type), Archimedes screws, and water turbines (Francis type, Kaplan type, Bulb type, Straflo type, etc.).
The following methods to assess fish survival are described:
— Survival tests involving the paired release of live fish, introduced in batches of test and control fish upstream and downstream of an installation, and the subsequent recapture in full-flow collection nets. The method is applicable to survival tests in the field and in a laboratory environment. (Clause 6);
— A validated model-based computational method consisting of a blade encounter model and correlations that quantify the biological response to blade strike (Clause 7).
The computational method can be used to scale results from laboratory fish survival tests to full-scale installations operating under different conditions (Clause 8).
The survival tests and computational method can also be applied to open-water turbines, with the caveats mentioned in Annex C.
The results of a survival test or a computed estimation can be compared with a presumed maximum sustainable mortality rate for a given fish population at the site of a pumping station or hydropower plant. However, this document does not define these maximum rates allowing to label a machine as “fish-friendly”, nor does it describe a method for determining such a maximum.
This document offers an integrated method to assess fish survival in pumping stations and hydropower plants by fish survival tests and model-based calculations. It allows (non-)government environmental agencies to evaluate the impact on resident and migratory fish stocks in a uniform manner. Thus the document will help to support the preservation of fish populations and reverse the trend of declining migratory fish stocks. Pump and turbine manufacturers will benefit from the document as it sets uniform and clear criteria for fish survival assessment. Further, the physical model that underlies the computational method in the document, may serve as a tool for new product development. To academia and research institutions, this document represents the baseline of shared understanding. It will serve as an incentive for further research in an effort to fill the omissions and to improve on existing assessment methods.

This document covers the arrangements for model acceptance tests to be performed on hydraulic turbines, storage pumps and pump-turbines to determine if the main hydraulic performance contract guarantees (see 4.2) have been satisfied. It contains the rules governing test conduct and prescribes measures to be taken if any phase of the tests is disputed. The main objectives of this document are: - to define the terms and quantities used; - to specify methods of testing and of measuring the quantities involved, in order to ascertain the hydraulic performance of the model; - to specify the methods of computation of results and of comparison with guarantees; - to determine if the contract guarantees that fall within the scope of this document have been fulfilled; - to define the extent, content and structure of the final report. The guarantees can be given in one of the following ways: - guarantees for prototype hydraulic performance, computed from model test results considering scale effects; - guarantees for model hydraulic performance. Moreover, additional performance data (see 4.4) can be needed for the design or the operation of the prototype of the hydraulic machine. Contrary to the requirements of Clauses 4 to 6 related to main hydraulic performance, the information of these additional data given in Clause 7 is considered only as recommendation or guidance to the user (see 7.1). It is particularly recommended that model acceptance tests be performed if the expected field conditions for acceptance tests (see IEC 60041:1991) would not allow the verification of guarantees given for the prototype machine. A transposition method taking into account the model and prototype wall surface roughness for the performance conversion on pump-turbines, Francis turbines, and axial machines is described in IEC 62097. This method requires model and prototype surface roughness data and is takes into account the shift in nED, QED and PED factors for determining the transposition of efficiency between model and prototype. However, in the case of Francis machines with semispiral casing and axial machines, the transposition method has not been fully validated due to a lack of data. In addition, IEC 62097 does not apply to storage pumps, Pelton turbines, and Dériaz. Therefore, for these and otherwise specifically agreed upon cases where hydraulically smooth flow conditions are assumed on the model and the prototype, the transposition formula and procedure given in Annex D and Annex I can be applied. Applications and limitations of both this document and IEC 62097 transposition methods are discussed in Annex E. The method for performance conversion from model to prototype needs to be clearly defined in the main hydraulic performance contract.

IEC TS 62600-202:2022 specifies the development stages of Tidal Energy Converters up to the pre-prototype scale (Stages 1 to 3). It includes the hydraulic laboratory test programs, where environmental conditions are controlled so they can be scheduled, and the first scaled system open-water trials, where combinations of tidal currents, wind and waves occur naturally and the programs are adjusted and flexible to accommodate these conditions. This document describes the minimum test programs that form the basis of a structured technology development schedule. For each testing campaign, the prerequisites, goals and minimum test plans are specified. This document addresses:
a: Planning an experimental program, including a design statement, technical drawings, selection of scale and facility based on physical laws, site data and other inputs; b: Device representation and characterization, including the physical device model, power-take-off components, foundation and mooring arrangements where appropriate; c: Energy resource and environment characterization, concerning either the tank testing facility or the open-water deployment site, depending on the stage of development; d: Specification of explicit test goals, including power conversion performance and device loads.

IEC 62364:2019 is available as IEC 62364:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62364:2019 gives guidelines for: a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites; b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site; c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems; d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings; e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers; f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life. It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues. It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation. Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydro-abrasive erosion resistant coatings can also be damaged locally by impact of large solids. It is beyond the scope of this document to address these issues. This document focuses mainly on hydroelectric powerplant equipment. Certain portions can also be applicable to other hydraulic machines. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the formula for TBO in Pelton reference model has been modified; b) the formula for calculating sampling interval has been modified; c) the chapter in hydro-abrasive erosion resistant coatings has been substantially modified; d) the annex with test data for hydro-abrasive erosion resistant materials has been removed; e) a simplified hydro-abrasive erosion evaluation has been added.
